I live on a farm in Piedmont NC, and use a solar photovoltaic array to provide the most critical electrical needs for my house. I use a Trace inverter/charger of 2,500 watts per leg to produce 120/240 volt 60 Hz power identical to what comes from the overhead pole line.

This particular inverter is designed to work with a 24 volt battery array; the batteries I use are actually 12 volt batteries, wired in series-parallel to provide 24 volts, 5600 amp-hours.

This system provides enough power to run all the lights, the refrigerator, this laptop and one other computer, music system. Two circulating fans, microwave oven, and the circulating pumps for a hot-water heat system embedded in the concrete floor slab.

The fans, pumps, and refrigerator are special energy-efficient models specially designed for solar electric systems.

This system was very expensive to build, and it will take 20 years at the present electric rates to pay for itself. It is very likely that electric costs will go ‘way up, which will shorten the payback time. The main benefit for me is the sense of independence and flexibility.

I don’t try to run air conditioners, shop tools, kitchen appliances, or a washer and dryer off the solar plant. I run these when I have to, and pay the bill. In the kitchen I have a gas range and a wood fired cookstove with a hot water tank.

Thus I have several optional ways of providing for most needs. The Trace inverter/charger automatically charges the batteries from the utility lines if the batteries get low, and the utility power is off, it will automatically start the backup generator and charge the batteries off that. I would have to have five (5) consecutive days of dark clouds and rain to make that happen.

You can find out all about how to do this on the internet. Most states have some kind of Alternate Energy information center that will provide you information related to local sources and requirements. Also, you can search for “solar electric system” on the internet and find tons of sites selling the components and sources of information.

Good luck!

Yes you could switch to a huge generator. The cost of operation would be more than the 10 cents per kilowatt the electric company charges. Check your local laws. You may be able to build a windmill. Any unused electricity is sold back to the electric company at their rates of 10 cents per kilowatt. You can also look into solar cells.

Both of these methods have high start up costs. Be sure and find out from the companies what they consider the time to be to start seeing results.

In the mean time there are many things you can do first. Reinsulate your attack to 12 inches of blow in insulation. Insulate your floor if you are on a crawl space. Caulk every where you can think of. Install double or triple plan vynal windows. Put electrical heat reducing fans on your attick. Get an electronic thermistat. And program it to different tempertures duing the day and night. Shut vents and doors in rooms you do not use. See in you can get foam insulation for your walls. By doing most of this you should lower your energy costs by 30% or more.

At 60 degrees latitude (north or south), and averaged over a year, the solar energy level is about 50% to 55% of the level at the equator. That’s not counting the effects of clouds.

A lot of the thermal energy at high latitudes comes in on wind and water movement; I guess you could say that is also a very indirect solar energy.

admin answers:

First, its all a guess but the sun will continue to shine for about another 2-4 billion years. So for all practical purposes, its eternal.
Solar energy depends on sunshine, one disadvantage is cloudy, overcast, rainy, snow etc. Days. No sunshine, no real energy. Another difficulty is converting solar energy, solar panels generate direct current (DC) and this has to be converted to AC current to run appliances, etc. In your house. In order to store solar energy, batteries are required, so the DC current from the solar panels can charge the batteries, and then the DC current must be converted to AC.
Solar panels are not cheap but the price is coming down. They also don’t last forever and can be damaged by hail, etc.
The good news is, solar energy is clean, not pollution except for the manufacture of the panels and for the moment, sunshine is still free.

Hi M A,

I’ll share with you some material provided by Dan Martin which I found very handy and very interesting:

“The one EV car I currently have (have 2 vehicles that run on hydrogen also) I converted from a vw bug and is free to charge. As I live completely off the grid all my electricity comes from solar panels and 2 wind generators, which I also built.

However I did charge up at Costco in Carlsbad California (I actually only drove up there to fill up) if I remember right it was around $2.00

Not sure if you’re interesting in doing it yourself, but I’d be willing to walk you step by step threw the conversion. I’ve converted 3 of my own cars (a datsun truck, ford ban, and a vw bug) and a few for neighbors. I’ve also converted cars to run on hydrogen, ethanol and biodiesel, by far EV is the easiest.

If you’re interested here’s what it would entitle…

– The engine compartment is first cleaned out of any gasoline components.
– Electric components are then installed in exchange.
– A battery bank is built and incorporated.
– Existing starter and driving systems are connected.
– Turn the key, step on the gas pedal sending more energy to the electric motor, & thus more power to the drive system, which in return creates more speed, more acceleration.
– The system has normal automotive top speeds and acceleration, typical to the vehicle your modifying. If your top speed was 85 mph and your acceleration was 1 mile per min, then this will be what your left with after the conversion.

The methods are extremely simple, making the process possible for anyone, everyone, ANYWHERE.

Typical tools, hardware & supplies are used, making access to parts available for all.

Electric Conversions can be easily accomplished in ANY model vehicle, even tractors, Generators, types of machinery, etc.

Project lengths range from 1 day to 1 month.
If you’re interested I wrote a guide on it which is available at www agua-luna com

My last EV conversion ran me about $1400. Everything is available online. I have a how to do it yourself guide available at www agua-luna com that will walk you step by step through the process. If you have ANY questions feel free to contact me through the site. Here’s a list of what you’d need…

Advanced DC Motor
The motor is an 8″ Advanced DC series-wound motor. It weighs 107 pounds and is rated at 68 peak horsepower. These motors are available in several sizes.

Adaptor plate
The adaptor plate mates the motor to the transmission. It is constructed of 1/2 inch aluminum and is pre-drilled with bolt hole patterns for both the motor and transmission. An aluminum spacer is also used for proper spacing between the shafts of the transmission and motor. Adaptor plates are available for many cars.

DC Motor Controller
The controller regulates current going to the motor. It is a solid-state device that uses a pulse width modulator (PWM) that sends short bursts of current to the motor at a rate of 15 kHz. Controllers are available from both Curtis and DCP.

Potbox (Potentiometer)
The potbox is a 5K ohm throttle between the controller and the accelerator, similar to the way a sewing machine pedal works. The potbox’s lever arm is attached to the existing accelerator cable.

Main Contactor
An electric relay that serves the same purpose as the ignition switch in a gas car. When the key is turned to the start position, the contactor closes the circuit to allow current to flow to the controller.

Circuit Breaker
A safety device that shuts down power for servicing or during an emergency. The circuit breaker is installed under the hood and can be switched both off and on from the drivers seat with an extension or cable.

Main Fuse
The main fuse protect the system from high voltage spikes. A fuse should be installed at each battery box or group of batteries.

Shunt
A shunt is placed in series within the wiring as a means to connect meters. Shunts are available in different sizes for both high and low power configurations.

Charger interlock
A relay that keeps the circuit open so nobody will inadvertantly drive off with the charge cord plugged into the car.

DC/DC Converter
The DC/DC converter is similar in function to a gas car’s alternator. It charges the 12 volt accessory battery by chopping voltage from the main battery pack down to 13.5 volts.

If you think wind and solar are free, or even cost competitive, you have not done the most rudimentary homework.

Wind is typically 3x the cost of coal fired power. It is unreliable; when the wind does not blow, you have to have a conventional power plant to back it up. The average output is about 20% of the installed capacity, so you have to build 5x as many wind generators as you supposedly need. When the wind is less than about 30 knots, the wind farm puts out less than full power, so you have to run the backup power station to take up the difference; but then it is operating at part capacity, so its fuel consumption and emissions per KWH generated are higher. Wind farms are low-intensity, meaning that they take up a lot of land for a given power output. One state figured out that to meet the state’s ‘20% renewable’ energy mandate with wind power, they would have to cover 1/5 of the arable land in the state with windmills. The neighbors don’t like them and the noise, especially at night. Even with the tiny percentage of the US power consumption we now get from wind (a few percent), the wind farms are killing 440,000 birds a year, and no one knows how many bats. The wind farm at Altamont Pass, CA (east of Oakland) is killing endangered golden eagles at over twice the rate that the population can sustain.

Solar has similar problems, and is even more expensive.

Probably because of years of big oil propaganda. I know I look a conspiracy theory nut saying this, but just look at some of these answers. Its sad. If they worked better, we would be using them. We aren’t using them, therefore they must not be better?? Are you kidding me? Do you know how much money oil companies spend lobbying not to spend grants on renewable energy research, or other forms of energy in general? Car companies and other industries that rely on fossil fuels like coal, natural gas, etc… Do this as well. They make too much money as it is, of course they dont want change.

We could make a lot of progress on renewable energy sources and ways to package it/store it if our government (and corporations) cared at all about anything more than money. General it they constantly say it isn’t an issue, and that global warming is fake, and that there is no alternative. We are the US for Pete’s sake. If it doesnt exist yet, then we should be making it happen. But no. We are controlled by greedy fat bastards

Solar panels currently being manufactured, have a design life of 20+ years.

Home-size wind turbines have a wide range of design lives. The turbine life is influenced by conditions of use — high winds, ice on the blades, etc.

I would recommend that you purchase your home-scale wind turbine from a seller who offers a guarantee to repair or replace the unit if it fails under normal use. A 5-year or 10-year guarantee period would be ideal.

You could supplement battery charging with a small wind charger and photovoltiac panels.

Many people are not using solar energy for their daily need, probably for 3 main reasons:

1. Lack of awareness
2. Cost of installation
3. Breaking off from the grid electricity or Integration to the grid electricity

Until lately, most people are not fully aware of the enormous energy that could be directly tapped from the Sun. It’s still costly to obtain the pvcs for collecting the sun rays to covert to energy and where most areas are connected by grid system, how does a standalone electricity generator blend.

This is a very important question!

I am a big fan of Dr. Jack Edwards from the university of Colorado. In 1997 he wrote a paper titled “Crude Oil and Alternate Energy Production Forecasts for the 21st Century; The End of the Hydrocarbon Era” Jack was an optimist and formerly in charge of Shell’s Research Centre in Houston. I will read some of his key predictions on “Peak Oil”.
Conventional Light Oil – 2025 All Oil – 2035 All Natural Gas – 2035 All Coal – 2040. Conventional Oil Peaks at about 38 Billion Barrels per year globally and tails out at 9 Billion Barrels by 2100. All other energies from fossil fuels face the same basic fate by 2100 as a percentage of Peak (9/38=23.6%) by 2100. The reasons for the decline vary, some are supply based, some are economics based and some are environmental (coal). He estimates that at Peak Oil that Nuclear will be about 5 Billion Barrels Equivalent or roughly 6% of total supply (I believe the actual current figure is about 8%). He shows Nuclear expanding to about 15 Billion Barrels or roughly 16% of total supply by 2100. The interesting fact is that by 2100 we will HAVE to obtain 35 Billion Barrels or about 37% of Energy from Solar, wind and Geothermal. Currently we obtain less than 3% from these sources!
None of Jack’s thinking revolved around such things as “cap and trade” and its chilling effect on the supply curve!If NA is ever going to achieve the substitution of the fossil fuel supplies with the alternatives, we will require that ALL sources of fossil fuels be exploited fully. Otherwise we will neither have the energy nor the economy to reach a 12 fold increase in solar, wind or geothermal let alone the substitution of another 22% of the energy supplied by coal! Theadagee of “it takes money to make money” is true and can be stated as “it takes energy to make energy”.

The Nuclear Industry will be essential in meeting energy demand, however the rush to meet the lofty goals of substitution will require absolutely enormous quantities of Capital and has the potential to create a catastrophic environmental and security quagmire! I am most afraid if the fact that there are environmental approvals (Nuclear) pending in my country, that in my technical opinion, are a catastrophe waiting to happen! Nuclear has a vital role to play, however when these kinds of $$$ are involved, big corruption and big mistakes are also in abundance. When I was in University, I learned that the Geotechnical aspects of Nuclear site selection were paramount in the decision tree. In reality economics are paramount and the Geotechnical safety issues are out 10th out of the top 10 considerations. Politics is the #1 consideration.

I fear for the long term economy of North America. There are going to be very major changes on the horizon, however it is possible to accomplish energy security but at a huge cost. The biggest risks relate to the economic uncertainty that current geopolitical movements such as “global warming” are causing. While these uncertainties exist…Capital will do nothing! This will make the problem deeper and broader, and the economy will continue to suffer.

Solar Panels In Cold Climates
By Anna on November 26, 2008

Contrary to popular belief, you do not need to live in a hot climate in order to benefit from clean renewable energy sources such as solar power. In fact solar panels convert sunlight into electricity more effectively in colder temperatures…………………………..This phenomenon is due to the fact that the colder a material is, the better it will conduct electricity. Therefore, solar panels will produce less electricity in a hot climate than in a cold climate given that the amount of sunlight is equal. It is true that colder climates tend to have less sunlight than hotter climates, but the reduced availability of sunlight is offset by the increased efficiency of solar panels in colder temperature.

A good example of this principle in action is the Photovoltaic Solar Power Plant in Colorado, near Alamosa. It is home to one of the largest photovoltaic solar plants currently operating in the United States.

I hope the above is informative…

I understand your objective Richard, but would sincerely recommend that you re-consider how you should go about achieving it.

I don’t recommend 12v batteries for your project and certainly don’t recommend using anything less than first quality batteries – you can still find them at low prices.

A better storage solution is deep cycle 6volt batteries. The 6v batteries will do a much better job, last longer, allow a deeper discharge and a higher number of re-charge cycles.

You want your batteries to be the same size, type and age to work together best. I use 4- 6v batteries in my RV along with a single solar panel and can stay out in the desert for days without ever having to fire up my generator.

Here’s a link to a great article on the subject:

admin answers:

Big Business is beginning to look at global warming through eyes blinded by dollar signs. Climate change is replacing tech and bio tech as the major investment theme of the future. Wall Street’s analysts are devising ways to cash in on weather.

Discussions have changed to talk of what a 1-degree rise each year in temperature would do to profits. Global warming is becoming a major market-moving force that represents a generational shift likely to influence how people invest for decades. The world’s biggest financial services firms are investing massive amounts of time and brainpower trying to pinpoint what stocks and sectors will benefit or be hurt by Global warming.

There are at least 74 companies in 18 countries that can profit from changing weather patterns. Global warming will change world economy. There is a company in California which manages the largest pension plan in America that has committed $800 M to invest in clean technology. At this time 90% of global warming is the result of human activity.

Temperatures around the globe could raise 2 to 12 degrees Fahrenheit by 2100. This will result in more intense heat waves, stronger tropical storms and a rise in sea levels that will swamp low-lying cities and farmland. When I was boating through rice fields in India last summer I wondered how these people would survive even a few inches rise in water. Most of the farmers live at sea level.

Corn will be used to create ethanol. If corn is used to provide even 10% of the nation’s automotive needs, it would use 35% of America’s corn crop. Since 25% of all food prices are affected by the cost of corn, we could face a corn vs. Food situation. Farm leftovers can be used to create cellulosic ethanol for fuel. Farm equipment companies should do well because farmers will be rethinking harvesting techniques. They will also retool their machines for the new fuels. Monsanto is working on creating more drought resistant crops.

Energy conversion devices and sun power are becoming buzz words. Windmills. Fuel cells. Solar panels. Several companies are developing types of clean solar panels with the hope of rivalling oil and coal, deemed “dirty” fuels. Eco technology is still too mature to make a lot of money. Solar will only create a tenth of the world’s energy. Technology that makes dirty energy sources like coal and oil cleaner. There will be more money made on the dirty stuff. Nuclear power generators are also on the rise. The new nuclear energy is much cleaner and produces no carbon.

Ethanol, hydrogen, clean diesel, bio diesel fuels hold promise for the future. Hybrid cars are the way of the future. The major car manufacturers are working on increased efficiency. Investing in hybrid vehicles and components and batteries etc will be good investments.

The insurance industry will change incredibly. So many energy and utility companies will all have to face different challenges due to the effects of weather. Suddenly they realize climate and profits are closely related. Investors will start to lean more toward green investments.

I also think security and protection companies might do well because the displacement of people and shortages could result in an increase in crime.

The world’s demand for energy is accelerating as China and India grow. Heavy construction and engineering companies that build power plants will do well. The smart ones will build ecologically sensitive plants will steal market share. They will find ways to make plants more efficient and cleaner. One technology, clean coal, puts devices in smokestacks that pull the carbon out of the exhaust and plow it back into the soil.

After Hurricane Katrina, folks are rethinking the option of coastal real estate. People will develop an aversion to locations on the water and severe-weather-prone areas. People will flee Florida for the Smokey Mountains for example. This covers Georgia, Tennessee and North Carolina. This is already happening. Also the high insurance premiums for living near the water affect property values.

Small parts and components that go into everything from washers and dryers to fighter jets and elevators could play a gigantic factor in curbing energy use. We already have the technology to reduce the world’s power use by 30% overnight. About 11% of the savings could be achieved with efficient electric motors inside washing machines, conveyor belts and other motors that use half the energy of older technology. Another 11% could be saved in transportation using hybrids. The last 8% can be saved with energy-efficient fluorescent bulbs. Currently businesses that focus on energy efficiency are already becoming more profitable.

The wealthier nations are in better condition to deal with these things. It is the poorer nations that will have serious difficulties. Holland could just disappear. A great deal of landmass will also be lost, which will drive up the cost of real estate everywhere.

That is how America sees the future according to Global Warming. In its usual entrepreneurial way, Americans see the silver lining of this problem as an opportunity for positive change and innovative growth.

No. Air drag is one of the chief components in auto efficiency. What you describe would increase air drag.
As far as the solar part goes most cars have about 12 square feet of surface in the sun when the car is in the sun. 12 square feet can produce 900 watts. In four hours that would be 2700 Watt hours. A gallon of gasoline is about 37,000 Watt hours. What means is is that it is going to take over 100 days to produce the energy of one gallon of gasoline and everything has to be perfect.

I came accross a new, proven and tested home made wind power system and solar power system which eliminates our electricity bills.

They already are, the Honda FCX and Toyota FCHV are both available for lease in some areas. The price for either car is probably prohibitively expensive which is why they’re only for lease, the fuel cell itself is very costly.

Right now, the hydrogen fuel cell is a poor idea for cars for the simple reason that it always requires more energy to separate it from whatever it’s bonded to than you can get back out by utilizing it. There are ways to make it more efficient but it’s still a losing proposition. As an energy storage medium it’s not efficient enough. Until we can use it in a fusion reactor it’s not likely to become our energy source whether it’s reformed from natural gas, made via electrolysis or by catalyzing metals. It’s just more efficient to use the energy directly instead of making the hydrogen and then either burning it or using it in a fuel cell.

Batteries or capacitors are better means of storing electricity and that electricity can be produced using a variety of renewable sources – with smart investment we could change to renewable power generation and electric cars within a few years.

I could be proven wrong of course, Honda is going ahead with it’s plans for the CVX and Toyota is doing the same. I do like the possibility of home charging and you can use the generator to power your home in the event of a power outage, as long as you continue to get natural gas supplied. But natural gas reformed into hydrogen isn’t terribly efficient and still relies on the fossil fuel model with associated problems.

If you use a high-efficiency method like QSI Nano claims to have developed and pair it with solar thermal tech then you may have a winner. This is even more true if the work by the Weizmann Institute proves practical, see http://www.greencarcongress.com/2009/04/weizmann-institute-scientists-demonstrate-novel-approach-for-splitting-water-into-hydrogen-and-oxyge.html#comments

Solar cells are used in electricity supply. In addition solar batteries can also be used which could store power generated from the sun and discharge the power as needed(through an inverter).

They’re called Amorphous silicon cells. They’re about 7% efficient.

Not unless you can figure out a way to produce a semi-conductor at home. Basically a solar cell (photovoltaic cell) is a couple of layers of silicon P type and N type. Electrons become excited when light quanta penetrates into the P layer. The excited electrons move to the N type and (very oversimplified) create electricity.

I doubt you would have the facilities to create the materials at home.

admin answers:

TV, lights and small appliances, yes. Washer, maybe. Dryer, not likely unless it’s gas – consider a clothesline. Electric range or oven, no. Hot tub, no unless it’s converted to a gas heater.

The raw panels are about $3-8 per watt. So for 6Kw figure about $18k for the panels. The charger/inverter and batteries, figure $2-3k more. Figure about $30k including the installation.

You might also consider a generator. The off-grid houses I’ve seen tend to have them, even if they have batteries too. Add $3k for that.

Do you have a creek? Consider small-scale hydro too.

What a bunch of crap. It really shows how corrupt our legislators are when they’ll only support the bailout bill if there are some goodies for their own causes. I wonder how many of them actually thought it was a bad idea but decided it was a good way to get what they wanted.

Solar energy can be produced from solar radiation. Sunlight travels through the upper parts of the earth’s atmosphere. Once this sunlight reaches the surface of the earth, it must be captured so it can be turned into an usable energy source. At the earth’s surface, it is called infrared radiation where it is captured through the aid of photovoltaic or solar cells.Once captured, the sunlight is absorbed into these photovoltaic/solar cells. These photovoltaic/solar cells are then used to convert the sun’s energy into electrical energy. These cells are non-mechanical devices that are made from silicon alloys. Most of the solar collectors resemble black, flat boxes that sit on building rooftops. In the most common design, pipes in the box carry liquids that transfer the heat from the box into the building. This heated liquid then heats the water in a tank or is passed through radiators to heat the air. Below are the common usage of Solar Energy:

Residential

The number of PV installations on buildings connected to the electricity grid has grown in recent years. Government subsidy programs (particularly in Germany and Japan) and green pricing policies of utilities or electricity service providers have stimulated demand. Demand is also driven by the desire of individuals or companies to obtain their electricity from a clean, non-polluting, renewable source. These consumers are usually willing to pay only a small premium for renewable energy. Increasingly, the incentive is an attractive financial return on the investment through the sale of solar electricity at premium feed-in tariff rates.

In solar systems connected to the electricity grid, the PV system supplies electricity to the building, and any daytime excess may be exported to the grid. Batteries are not required because the grid supplies any extra demand. However, to be independent of the grid supply, battery storage is needed to provide power at night.

Holiday or vacation homes without access to the electricity grid can use solar systems more cost-effectively than if the grid was extended to reach the location. Remote homes in sunny locations can obtain reliable electricity to meet basic needs with a simple system comprising of a PV panel, a rechargeable battery to store the energy captured during daylight hours, a regulator (or charge controller), and the necessary wiring and switches. Such systems are often called solar home systems (SHS).

Commercial

On an office building, roof areas can be covered with glass PV modules, which can be semi-transparent to provide shaded light. On a factory or warehouse, large roof areas are the best location for solar modules. If the roof is flat, then arrays can be mounted using techniques that do not breach the weatherproofed roof membrane. Also, skylights can be partially covered with PV.

The vertical walls of office buildings provide several opportunities for PV incorporation, as well as sunshades or balconies incorporating a PV system. Sunshades may have the PV system mounted externally to the building, or have PV cells specially mounted between glass sheets comprising the window.

Industrial

For many years, solar energy has been the power supply choice for industrial applications, especially where power is required at remote locations. Because solar systems are highly reliable and require little maintenance, they are ideal in distant or isolated places.

Solar energy is also frequently used for transportation signaling, such as offshore navigation buoys, lighthouses, aircraft warning light structures, and increasingly in road traffic warning signals. Solar is used to power environmental monitoring equipment and corrosion protection systems for pipelines, well-heads, bridges, and other structures. For larger electrical loads, it can be cost-effective to configure a hybrid power system that links the PV with a small diesel generator.

Remote Applications

Remote buildings, such as schools, community halls, and clinics, can benefit from solar energy. In developing regions, central power plants can provide electricity to homes via a local wired network, or act as a battery charging station where members of the community can bring batteries to be recharged.

PV systems can be used to pump water in remote areas as part of a portable water supply system. Specialized solar water pumps are designed for submersible use or to float on open water. Large-scale desalination plants can also be PV powered using an array of PV modules with battery storage.

PV systems are sometimes best configured with a small diesel generator in order to meet heavy power requirements in off-grid locations. With a small diesel generator, the PV system does not have to be sized to cope with the worst sunlight conditions during the year. The diesel generator can provide back-up power that is minimized during the sunniest part of the year by the PV system. This keeps fuel and maintenance costs low.

Petrol? 🙂
You can’t use a fossil-fuel-burning generator in space because it would cost a huge amount to transport the fuel and the oxygen to burn it from earth. Also you would have to get rid of all the heat, which is not easy in a vacuum.

The ISS uses solar panels to provide all its electrical power. The panels are only illuminated half the time of course; when it is on the night side of earth they generate no electricity so the station runs off rechargeable battery packs during this time.
The total power available at any time is 110KW.

Yes, because at a high altitude, the sunlight would pass through a thinner atmosphere . This means that the atmosphere would scattered less energy away.

Simple answer, you need a multi-input grid-tie inverter.
My dad has one on his DC solar array. It can accept between 50 and 270 volts DC which is good for solar because he can wire them in series to add the voltage rather than parallel adding amperage which requires larger wires… Etc.
There are permanent magnet alternators you can order online that will produce pure A/C with no voltage limitation so you can control the output voltage via rpm governance. You could set things up to produce 120v A/C and tie directly in. You still need a grid tie device to protect your equipment and the grid.

Now the issue you will come into with an alternator generator is no control mechanism to compensate for load. Electrical generation is directly proportional to torque. If you put a heavy load on the system, it will become harder to turn which could slow down your rpms and in turn lower your voltage.

For this reason, alternators are typically used to charge battery banks which connect to an inverter.
You could wire a lot of batteries in series to get a higher voltage capacity and just rectify the A/C before it hits the batteries. Then you get a buffer allowing your alternators to have a range of output voltage which will give leeway for rpm fluctuation. And since the batteries will be a predictable load you really should have no trouble maintaining a steady speed.

Now I am guessing that you must have your driving force figured out. Generally speaking there is a direct conversion of horsepower to watts. 1 hp of torque will produce about 750 watts of power at top efficiency.
Steady water flow in a well designed system can easily exceed 40 hp in a single turbine which could drive several alternators. Steam is another good alternate fuel source. Solar concentration is often used to produce heavy steam generation. The trick is tuning the focus to achieve about 550 degrees or so, to get saturated steam. The down side is you only produce when the sun is out. I have an idea for combining these two concepts together. Use heavy solar concentration to turn the lower water pool into steam to lift it back to the top, while also condensing it through a turbine at the top. It’s a question of, how much sunlight will it take to move enough water that you have a nightlong supply running back down?
Seems like a major undertaking. It’s quite difficult to direct sunlight from a large array at a low position. Much easier to target the top of a tower.
Anyways, finely polished metal is the best way to reflect the most energy. I’m interested in building a smaller closes loop system for potentially scaling up. I’m wondering how high I can get the water via steam, and how many turbine stages it can fall through… In theory I can heat that steam continuously for hundreds and even thousands of feet of rise. Rocky Mountains are a good place to try that…
This kind of system could be ideal for property where there is ground water available but no naturally flowing surface water. You could even incorporate a distillery and fish pond, irrigation, etc.

I can’t divulge my ultimate experiment that this ties to. I think I figured out a way to store energy even better than batteries and raised water tanks.

It makes a big difference where you are located, what resources are available, if you are working with new construction or renovating old existing work.

In general, any path to energy independence is going to start with conservation. With heating and hot water this may mean point of use heaters, insulation, heating surfaces instead of the air (radiant heating costs less in operation) ventilation instead of air conditioning, earth tubes etc. Start to satisfy your existing 100% of current energy demands you may be able to achieve 20 to 30% with conservation techniques.

We feel warmer if surfaces are warmed than if only the air is warmed. It is more efficient as the surface temps can be 10 deg lower than we would normally heat the air. Radiant heating in floors and sometimes walls works well with both solar thermal panels and geothermal as a heat source.

In new construction a masonry stove (not cast iron) can be a very efficient use of wood. It may be lit once per day to a very high heat. The balance of the day and night the massive masonry structure radiates heat to the dwelling.

Geothermal, ground source heat pump applications are a kind of alternative form of heating conservation. It saves heating costs but still requires some energy. It does not yet supply more than it requires.

Solar thermal is 60 to 80% efficient vs photovoltaic which is only about 8 to 22% for the homeowner. There is some speculation that solar thermal plus a stirling generator may be several times cheaper than photovoltaic panels for producing electricity. ($1/ watt vs photovoltaic $5/watt.) Heat is also easier to store than electricity. So store heat to make electricity. Solar thermal comes in several designs for residences. In new designs it is in passive solar heating. For both new designs and retrofits a solar sun room may provide additional heat. Solar thermal systems can active or passive. Active systems have pumps. Solar thermal panels can be flat plate or vacuum tube collectors water based collectors or air collectors that have no liquids in them. Solar thermal energy can be used for heat, hot water, air conditioning and to generate electricity with a mid temp range stirling engine/generator.

It also would be possible in more rural settings to generate your own natural gas with a bio digester. It would however require massive amounts of bio fuel. However if the supply exists it is certainly a possibility.

While wind turbines are a possibility for electrical energy there is the duel problem of having power when you need it. First the wind must be blowing with sufficient strength and secondly there needs to be some type of energy strorage capacity. This storage shoud have deep cycle capacity. Heating water or a phase change material may be one option. Chemical storage may be another (hydrogen) Pumped hydro may be practical in some locations. There is some discussion of using compressed air for storage. This might give a byproduct of heat that could be used to some benefit. Otherwise we are left with batteries.
