Your Questions About Solar Energy Generators For Sale

Chris asks…

how much solor energy would be needed to run a air conditioner?

admin answers:

Far more than you can afford.

A 3 ton central air conditioner draws about 7,500 watts. The sun doesn’t shine all the time, indeed you typically get less than 8 hours of usable sunshine for photovoltaics so you have to generate three times the power that you need in order to run the air conditioner around the clock so that’s 22,500 watts. Inverters are inefficient and are more inefficient the bigger they get to the point where motor generators are used with large sale DC to AC conversion, however most solar systems use an inverter so you’ll likely to have 60% efficiency therefore it’s 37,500 watts that’s needed. Air conditioners are ideally sized to meet the cooling demands as closely as possible as a short duty cycle results in high humidity so let’s say it has an 80% duty cycle, that brings the requirements to 30,000 watts. A solar cell costs $1.20 a watt to manufacture in China and $2 a watt to manufacture in the US but by the time a system is installed, it would likely be $5 per watt so your solar panels would cost $150,000. Oh, and you won’t have enough roof space facing the Sun.

If you do want solar powered air conditioning, your best bet would be evacuated tube solar thermal panels running an absorption air conditioner. But this won’t be cheap either and it will probably still require natural gas as a backup source of heat and it would mean completely replacing your air-conditioner.

Sandy asks…

Advice for building a solar generator?

We are moving to a remote location without any electricity, and would like to produce our own. We have read that it is pretty easy to set up solar power, and there are ready-made solar generators for sale. If we build our own, how many solar panels would we need to comfortably power a small cabin, and what other materials will we need to set it up? About how much will this all cost?

admin answers:

A solar electric system consist of in simplest terms a panel, charge controller, battery, and a load “lights, radio, etc”. This system can be expanded on.
The first item you need to consider is the loads, what do you want them to be. How much energy do they consume per hour and how many hours a day are they used. The next is the voltage of the items 12volt dc, 24 volts dc, 120 volts ac. In general 120 volt ac itmes are easier to obtain but in general less effeciant but also have longer life spans then the 12 and 24 volt dc versions.
Example we use 1 light bulb that consumes 20 watts at 12 volt for 4 hours a day. This buld would need 20*4=80 watts of energy per day. Next lets say you had 5 of these light bulbs and they were all used the same amount every day, you would need 80*5=400 watts to run these lights. Next lets say you want 2 days of reserve enegy incase it rains or something 400 *2=800 watts.
These 2 figures help give us the panel and battery size. Lets look at the panels first. We determind we needed 400 watts per day. Look around on the interent and you will find a chart with hours a day of sun light for your area. Lets say your area get 2.5 hours of direct sun per day in the worst time of year you would need 400/2.5=160 watts of panels.
The next figure is the 800 watts of battery. You never want to discharge your battery more than 40% this will reduce your battery life. So lets do the math again. (800/40)*100=2000
Now lets assume your battery back is 12 volts 2000/12=167 amp hour back.
So your system would consist now of 160 watts of solar panels 167 amp 12 volt battery bank a charge controller mounting system for the panels, box for the batteries, and an small fuse or breaker panel to protect all the equipment.
This would be a very simple system but if you wanted to add tv’s radios computer etc. You need to do the load calcs on them add them all together and do the math. Don’t just go out and buy a system someone off the internet sales you it may not be right for what you need.
Something else you will need to see the sun most of the day no shading of the panels. Good luck solar is great.

Your Questions About Solar Energy Calculator

Helen asks…

Can you get solar energy from a household lamp ?

Can you get solar energy from a household lamp?

admin answers:

Jordan is technically correct. But if you mean to ask if light from a lamp can produce electricity in a solar cell, then yes it can. But the amount of power the solar cell would produce is always less than the power needed to make the lamp shine, so there is no point in doing it. Except possibly for using a hand held calculator that has a solar cell on it and no battery. The light from the lamp will be enough to power such a calculator.

Charles asks…

How do you determine sun angle to apply in passive solar design?

I’m trying to self-educate myself in principle of passive solar construction. I have a basic understanding of the principle behind it:
-Capture winter sun
-Block out Summer sun
-Thermal mass to store energy
-southernly facing within 15 degrees of true south

My question is, how do you determine/calculate the sun angle to accomodate the principle. I can do a sun angle calculator but I don’t know how to interepret and apply the output: for example:
how would I determine the angles winter & sun angles ( picture: http://www.spartansaving.com/solarenergy/passive-solar-heating/) based off of information received:

Lat/Long: 37.05N / 94.51W
Altitude Angle: -17.73
Azimuth Angle: -74.22
Clock time: 6:00am
Solar time: 5:38am
Hour Angle: -95.43
Declination: -22.97
Equation of time: -0.06
Sunrise: 7:28am
Sunset: 5:15pm

**the above is just an example of a given day***

Now that I have the data for that one day, how would I use those figures to determine the winter & summer critical sun angles?

I understand thats just any day and I think I would need the figures for for the beginning and end of the solistices to get a span, but what do those figures above tell me?

How would I use them to draw a diagram (like the link provided) for any given location to ensure enough glass would capture the maximum amount of sunlight in winter but determine enough overhand to block the sun?

THANKS IN ADVANCE!!

admin answers:

The basic critical angle is 90 degrees minus your latitude. The sun angle will vary +/- about 23 degrees from this.
I found that I put an awning above my 2-story south windows which was just wide enough to completely block the sun at the summer solstice. This gave a varying amount of insolation throughout the year without the hassle of tracking.

Ken asks…

zombie survival?

what would you do if the world was taken over by zombies, and why?

admin answers:

Gather up people and fortify a position in orange county.

About 2-3 years into zpaw we move north to Idaho or something, a climate more suitable for farming and a area more remote.

I’ll distribute my guns (there’s 3)- my dad will take my shotgun, I’ll take the SKS and my bro will take the .22lr. I have at least 1000 rounds of each, so there should be no problem defending ourselves.

We group at Irvine High School, a small task force will weld all exterior doors shut, another force will weld bars over every window. The third will block all gated entrances by first chaining them shut, except for the back one.

Once this is done, I take 5 people with me, the SKS and shotgun. The rest will remain at the citadel with the .22lr, where they are very safe.

My little group will go into the chaos and get food, water, and some very nesscary supplies. Guns are needed because by this point people will be fighting over food and water. We pull up in front of Ralphs, One remains in the van with a bat and a machete. I lead with the shotgun hidden under my jacket (stock cut off), three people behind me grab shopping carts to fill up, the bring up the rear is another friend with the SKS in plain sight.

If we meet armed resistance, we open fire and leave trail of dead bodies. First is to grab is fresh produce and food, then bottled water.

We go back to the citadel to off load our supplies, then head off o big 5 sporting goods. Its a sporting store with guns, we break the crappy wooden lock bar with a crowbar and grab all the guns, ammo, and camping supplies, head back to the van, drive forward some and take some more food from the nearby albertsons.

Again, off load at the citadel and give out our newly acquired long guns to everyone. I trade in my shotgun for a 10/22 rifle, and off we go, another trip to the gun store. We head up Tustin Ave, now packed with cars, so we drive on the sidewalk. First to a storage place, we we trade in the van for a large truck. Then up to Fowler’s guns, which should be empty of people and very well locked up. We borrow a car someone’s car left on the road and drive it into the store front, go inside and grab every gun, ammo, and cleaning/reloading they got. Same for Turner’s outdoorsman. At Army-Navy We take all the camping things they have.

And on the way back take a second truck and go to home deport / lowes (whatever it is) and get some building materials, generators, fuel, BBq machines, solar panels, tools and more stuff. Then we head back to the citadel.

With our newly acquired weapons, ammo, tools and materials, we first park the truck in the gated autoshop area, Which we first reinforce with additional barricades and steel. Then we offload everything. Everyone can now get their gun or choice, plenty of ammo, take a room to sleep in.

During week 1 we set up patrols, which will patrol the roof tops and shoot any zombies we see, we set up the kitchen, the BBq machines we picked up cooks the meat we got form stores (packed in dry ice), bread, fresh produce and milk is also around to consume first.
The generators and lugged to the amphitheater area, set up.
The locker rooms are ventilated and cleaned, prepped to store the guns and ammo we have, including any fuel and dangerous things.
The aquatics center has the pools drained and filled with fresh water (thats 4 Olympic pools)

Week 2
we break up the cement in the quad to make room form farmland
we clear surrounding neighborhoods and salvage for additional supplies, tools, or materials.

After that, we continue living for a couple years, get good at farming and independence, then move to Idaho with electric cars (no gas worries) and set up a new walled city there.

Your Questions About Solar Energy Generator Suppliers

James asks…

what are solar energy converters?

i need to do a presentation on solar energy converter…can someone please suggest me a site where i can look for matter related to the topic….

admin answers:

Abstract
A solar energy converter includes: a light-concentrating instrument; an electron emitter in an insulated vacuum vessel, emitting electrons in a vacuum as a temperature rises by sunlight; an electron accelerator within the light-concentrating instrument; a cathode on a surface of the electron emitter opposite to a surface which is irradiated by sunlight, and electrically connected with the electron emitter; an electric field supplier having a positive terminal and a negative terminal; and an electron collector in the vacuum vessel, collecting the emitted electrons flying from the electron emitter toward the electron accelerator; wherein the electron accelerator is connected with the positive terminal and the cathode is connected with the negative terminal to generate an electric field, and the electron collector is used as a negative generator electrode and the cathode is used as a positive generator electrode in which the collected electrons migrate to the electron emitter to generate electricity.

Sandy asks…

what are the main european power stations?

admin answers:

The EU use various sorts of power, ranging from fossil fuels to renewable energy: coal, gas, solar thermal, hydro, wind, nuclear.

If you want the names of a few major power companies…

RWE npower is one of the UK’s leading electricity generators. Its parent company, RWE is one of the leading international utility companies. The company provides customers with electricity, gas and water as well as services related to these products. The company’s core markets are Germany, the UK and Continental Europe.

There are other national energy supply companies such as Eon in Germany and Gaz de France. There is also the power supplier E.ON UK.

In addition, EDF already has a significant presence in the UK energy market with its purchase of London Energy, Seeboard Energy and SWEB Energy. The company operates 58 atomic reactors in France and is expected to be among those firms bidding to build the new nuclear plants.

The E.U. Already imports half of its energy. By 2030 that figure is set to rise to 70 percent. While Europe has managed to reduce its dependence on oil since the crises of the 1970s, imports still account for three quarters of oil consumption and are expected to approach 90 percent by 2030. In Europe, natural gas is expected to be the largest energy source after oil, but before coal and lignite. Already 15 percent of electricity comes from gas power stations.

At present, nuclear power generates 35 percent of electricity within the E.U. The popular alternative to coal for electricity generation is natural gas. Already 15 percent of electricity comes from gas power stations, and this is expected to rise to 40 percent by 2030.
