Your Questions About Solar Energy Calculator
Lizzie asks…
Is it possible to use solar panels from calculators and make a super solar panel?
I was doing a project how I want to change my school. I came with an idea to use solar energy, but solar panels are expensive. That got me to another idea. Is it possible to take those tiny solar panels from old calculators schools don’t use anymore, and connect that with lets say a million more calc panels. That way, you can create one big panel. Could this be possible? Why or why not?
admin answers:
That might be more expensive than a big solar panel. Unless all these calculators are already there and being thrown out.
In theory, you should be able to do it. But you’d need a LOT of those little guys. More than you think. Say you want a 1 by 1 meter solar panel. Each little solar panel is like 3 cm by 2/3 cm. That means that you’d need about 5000 calculators to do it.
Also, you’d lose some efficiency with all the cables, as that is a lot of cable to go through before reaching the end of the circuit.
You should be able to get about 1 kW per day out of that if you live in a somewhat sunny area, and the solar panels you use aren’t too old.
That’s all very rough math using off the top of my head numbers, so I could be off by an order of magnitude XD
If you have the calculators, then it should be a pretty neat school project though.
Helen asks…
How solar energy in converted into electricity and stored? what is that electrons or chips and batteries?
The so-called panels consist of some chips?what are those chips?Solar power stored in some Batteries.What are those batteries? Whether these panels can be manufactured in a small set up like any other Village Industries.OR How the heat generated by the solar energy can be transmitted to a copper coil and generate heat in it?
admin answers:
Solar or light can be converted into current and batteries can be made at a smaller scale. Example is, small calculators are powered by solar cells.
As for as construction of those batteries they are made of smaller cells and then smaller cells are joint with other smaller cells to make little large cells. Its very expensive to make them on commercial level thats why we are addicted to oil.
Cheap things sometimes don’t come cheap.

The Different Types Of Solar Power Battery Chargers
The issue of solar power is becoming one of quickly increasing popularity, and the topic of solar power battery chargers is of great overall significance to this subject. There are many different types of solar power battery chargers available and knowing and understanding each of the separate types is truly crucial and essential in order to understand the solar power process as a whole.
What Are The Different Types Of Solar Power Battery Chargers Available?
The most common types of solar power battery chargers are: automotive solar power battery chargers, PDA solar power battery chargers, 12 volt solar power battery chargers, and travel solar power battery chargers.
An automated solar battery power charger is the superior product for anyone’s automotive needs, as it is a compact car charger which allows you to simply plug the device into the cigarette lighter of the car and will charge the car battery through this. This solar battery charger allows you to start your car quickly and easily even after leaving it for a lengthy period of time and, as well, it will actually prolong the life of the car battery and keep the overall level of the car battery constant.
The PDA solar battery chargers are typically made with high density single-crystalline solar cells, and each unit includes a solar panel that will charge your PDA within hours. The basic qualities of the typical PDA solar battery charger are: unbreakable solar panel, relatively inexpensive, lightweight design, will charge in the car window, will not damage your batteries and has a built in charge regulator, and will be able to charge any batteries under the standard 60 watt light bulb.
As for the 12 volt solar battery chargers, these offer an incredibly affordable and reasonable solution to the providing of power to any 12 volt battery system, and each battery typically includes a built in circuit in order to prevent any battery discharge as well to prolong the actual life of the used batteries. Typically there is no assembly required with this form of solar powered battery charger, and it is used to keep 12 volt and 6 volt batteries up to charge.
Travel solar battery chargers are chargers which are specifically designed to charge AA batteries, and which typically have a built in battery box which allows for the insertion of up to four batteries.

Your Questions About Solar Generators For The Home
Linda asks…
What solar equipment is necessary to power a steam generator for a home steam bath?
The generator I have is rated at 12 KW, requires 220V and 33Amp service to heat a room of 500 cubic feet. The power is only needed periodically and for short periods of time, 30 – 60 minutes a day. (on a rare occasion, twice a day.) How do I plan, organize and calculate the required equipment?
admin answers:
You want to power it with Photovoltaic panels?
Or are you asking about passive solar pre-heaters?
If you are going to buy Photovoltaic panels, just call up a install firm and get some. There is a 30% tax credit for them now even. But why you are specifically tying the PV panels into your sauna is just confusing. It would sure make for an expensive sauna.
Sandy asks…
easiest way to quiet down a portable generator?
I am looking to run a generator to power my mobile home when my solar and wind generators aren’t making enough power. I usually park in semi suburban areas and the last time I ran my generator for a prolonged period I got a noise complaint and had to move at 3am [not so fun] what are some ways to quiet down the generator while its running?
admin answers:
I had the same issue with an air compressor. I built a wooden enclosure with a small fan to bring cool air into the box. It has worked fine for over twenty years! But for your problem:
Find a cardboard box that will fit comfortably, upside down, over the generator. If that is not enough, glue some fiberglass insulation inside the cardboard box. That will decrease the decibels sufficiently. Otherwise, you will need to build a wooden enclosure with fiberglass insulation inside.
Good Luck

Lizzie asks…
What would your two weapons of choice be if your town was being attacked by zombies?
I would carry a double barrel shotgun with unlimited shotgun bullets and a chainsaw?
Also your the soul survivor so where would you go.
admin answers:
I’d find an industrial 2,000 watt laser, and power it with deep-cycle marine ni-cad batteries inside my armored track-vehicle. When they attack at night, I’d have plenty of spare power to slice them from any range. Wind or weather have no effect on aiming and there is not much noise. Daytime hoards would be easy to repel.
The shotgun is a satisfying tool for blowin’ zombie heads apart. But it gets hot with constant use and ammunition is heavy. It takes time to reload.
A laser can always keep cutting ‘em down.
Batteries have mass, but the energy that they store has almost no mass. The laser’s energy supply could be recharged indefinitely, which means I wouldn’t have to risk trips into urban areas to commandeer ammo.
Also, guns are noisy, and so, always give away your position. Zombies are slow, but when there’s a bunch of ’em, I want every tactical advantage.
A laser in the ultra-violet range is invisible, so unless Zombie-vision mutates to see in those ranges, they would not know where the blasts are coming from. They’d just see their zombie pals’ heads exploding for no reason. Even if they could see in ultraviolet ranges, laser blasts are short, and at the speed of light, the source would be impossible to locate. A Laser would not make noise to reveal my high-tech sniper-position.
Sure, capacitors and engines make some noise, but that could be easily muffled, especially in a heavily armored vehicle. If I forgot to recharge my batteries, or something malfunctioned, the vehicle itself could be a formidable weapon. I’d just escape by driving over them in crowds or individually, doing my best to crush their zombie-brains to oblivion on the way!
As the sole survivor, I’d drive to an unpopulated area with a flowing stream, woods (so I could rebuild with simple tools like a chainsaw) and fertile land for growing crops. Also, the chainsaw could be an effective ancillary weapon in case some random zombies were able to sneak up on me while I was building my log-fortress.
I have built log homes before. They can be very strong, weather proof, and I believe zombie-proof with a few modifications. Building cabins by yourself is hard work, so one of the first things I’d do after the major conflicts were over, is commandeer some heavy equipment like bulldozers, graders and back-hoes. Of course I’d have to also get a large stockpile of gasoline, kerosene and oil to fuel and maintain them. I figure that would be pretty easy in a post-apocalyptic America. There would be plenty of gas-stations left unattended, lots of tool stores, and probably giant building supply stores with pre-made materials! I have always wanted to buy an entire Lowes or Home Depot! Man, this is starting to sound like fun!
I like the Catskills, so if the initial attacks came from New York, that would be a good choice. But I also like Vermont, and the rolling mountains of the southern USA.
I would prefer a hillside or small mountain with a south-facing exposure. That way I could build a solar array to capture solar energy. Living near a fast flowing stream would allow a water-powered mill and generator, and the uphill walk would be harder for those slow-moving zombies that accidentally discovered my location. Having redundant energy sources seems like a sensible idea.
Another benefit of locating in the south: red neck zombies are even slower and stupider than regular zombies. That makes them easier targets. Plus, it would just be so much fun to shoot red neck zombies!
Zombies tend to congregate in urban areas, since it is a more target-rich environment. If a few remaining stragglers stumble (literally) on to my property, then I’d have plenty of time to see them, and cut ’em down with the laser from my mountainside fortress or from inside my mobile laser vehicle. A little action now and then would keep me from getting bored.
No zombie-movie has ever made it clear exactly what causes zombie-ism, but the method of contamination is always the same: contact with zombies. We never know whether zombie-ism is caused by a virus, a bacteria or some biological experiment cooked up in a government laboratory.
I wouldn’t take any chances. I’d leave the rotting corpses of zombies far away in the in remote small towns, out in the sun to bake until they were bone dry. That way, any potential infection possibility would be practically nil. If there were too many, I’d put on a haz-mat suit and bulldoze them into huge piles, then torch ’em with gasoline. Even the undead can’t walk or do much harm if their muscles are cooked off the bone, their bones are crushed to powder and their brains are vaporized.
Ahhh… I can see it now…
My impenetrable mountain fortress… A windmill, a water wheel, solar panels galore, fertile fields for raising food, and in the distance, the decomposing corpses of red-neck bible-toting zombies. Just me, an invincible sodium laser, and an armored track vehicle. Sweet!
Mark asks…
physics geniuses please help: In the generation of electricity is permanant magnetic material neccessary?
That is I know induction is the cutting of magnetic field lines with a coil of wires, but the plants don’t use iron lodestone like the examples in textbooks do they?
They must use electromagnets. But then the question is how does the current from the electromagnet originate? I suppose you could use a battery?
In a nutshell, please answer the following questions.
1) Is permanant magnet material neccessary to generate electric current?
2) is permanant magnetic material present in the generators one would buy from home depot or something?
3) and do coal powered power plants use permanant magnets to form the current that runs the electromagnets that spin within the massive generators?
admin answers:
1. No. Solar Power.
2. Yes. When you use a rotary method(wind turbine, gas engine, hydro turbine) to generate electricity, there has to be an existing magnetic field.
3. Yes.

Why Use A Solar Power Battery?
Solar power is known to provide a number of benefits out of which one is energy. The main reason why solar energy is pursued is for the protection of the environment. Today, our earth is faced with drastic circumstances due to pollution, which is caused by every single one of us in one form of the other.
Take batteries for example, from the type that you use in your flash light to those used to run a car, they all pollute our earth. Choosing solar power battery is one way in which you can help prevent pollution.
Helpful Information On Solar Power Battery
In order to get the right solar power kit to charge your batteries you must determine how much energy the size and energy required by these.
Different types of batteries require different temperature in which they can be charges such as lead-acid batteries, which at 40 degrees F will provide about 75% of its capacity and at 0 degrees F just 50%. Amp hours are used to measure the storage capacity and the amount of energy a battery can hold.
A solar power battery will be able to hold and provide energy for the amount of time it is not exposed to the sun and in cloudy conditions as well.
There are two types of solar power battery wiring used in order to produce energy for the same and they are parallel wiring and series wiring. Series wiring increases the volts and the parallel wiring increases the amps.
Solar Power Benefits
Whether you use a solar power battery or you have a whole solar powered home you can only benefit from this source of energy. It is environmentally friendly and cost effective in the long run.
Millions have turned to solar powered products from household appliances to cars that have solar powered batteries. It is important that we acknowledge the importance of switching to more environmentally friendly products, which will in turn provide us with a healthier planet.
Even though solar power has been used for centuries and without which life would not be possible on earth we have not used it to its fullest capacity. An expensive investment even if you are just going to use solar power batteries but definitely worth it in the long run not only for yourself but for generations to come as well.
Conclusion
Even the smallest changes such as using solar power battery will help in preventing pollution and making the earth a better place to live in. This itself should be reason enough to make anyone start using solar powered appliances today.

The most common website I encounter is DIY solar panels. The claim is that “for under 200 dollars you too can build your own solar panel and save thousands” I do not dispute the validity of that claim. I do take issue with what they don’t say. There are some building code violations to say the least. I have posted a blog on this very issue, and will continue to do so on a weekly basis. It is my goal to bring clarity to the cyber solar world. Check out my post “To build or not to build that is the question” at http://www.solarmandan.com.

Ruth asks…
How much does it cost to put solar panels on a house? ?
I want to be more green and if I get the panels will I still have a regular electric bill?
admin answers:
Yes, and no.
My cottage is primarily solar powered. However, we’re only there on weekends, and we’re only powering a small fridge (the biggest power draw, by far), televisions, stereos, lights, a water pump, and that kind of thing. For the more powerful items (vacuum cleaner, air conditioner, power tools, washer and dryer) we use a gasoline generator. Our water heater and stove are propane.
We have an array of seven solar panels, and two battery banks.
Obviously, we don’t have utility bills for our cottage.
We will soon replace the solar panels with more efficient ones. Currently, there are 85W panels on sale for $500 CAD. We will buy as many of those as we can afford. We recently had to replace one battery bank.
At home, we currently have a geothermal heating/cooling system. That cuts our energy use for heating and cooling quite a bit. That’s reflected on our utility bill. (Because we’re not in the city, we have our own well, plus a septic tank. So, our only utility bill is for electric.)
My husband and I have discussed it many times and, based on our experience with our cottage, we don’t think we’ll try to do a “whole home” solar system.
Typical estimates for panels, batteries, inverters, etc., to run a typical city home are in the $17,000 range. But with our cottage experience, we know that the real monkey wrench with solar power is STORING that power. And we’ve had more battery problems than we anticipated. Once the batteries are no longer holding charge well, they have to be replaced…and they’re expensive….and heavy…and have to be disposed of as hazardous waste. Our cheapest batteries are probably $200 each. We also use more expensive / bigger 6V batteries. We may even, one day, switch to the huge, very expensive 2Vs.
In any event, I find that the best way (for us) to incorporate solar power into our urban home will likely be panels which will provide power when the sun is shining, but still be on the grid for night time, bad weather, and times of excess power use. That will eliminate the expense and problems of batteries and power storage (and limiting power use, so as not to run down the batteries).
In some places, the excess power you create with solar panels can be put back into the grid, and the local power utility company will pay you for it.
So, for me, based on my experience, that’s what I think I’d do, when it comes time to outfit our home with solar panels. Using only solar power for the bulk of our living at the cottage is great, but we do have to be mindful of how much we’re using. Once the stored power drops below a certain point, the inverters won’t work, and you have to either go without power, or turn on the gas generator. I wouldn’t want that hassle at home.

Solar Power Air Conditioner: Past And Present
The need to utilize solar energy is being thoroughly appreciated by innovators, so much so, that now their inventions become almost paradoxical. What else, but paradoxical, would you call an invention like the solar power air conditioner? It is a device that cools down the heat generated by solar energy falling on earth, while itself working by absorbing this very heat energy. What surprises more, perhaps, is the fact that the idea of cooling rooms and living places with solar energy is anything but new.
The Romans’ Ancient Solar Power Air Conditioner
It evokes wonder to know that the Romans, in their acme of civilization, used a natural form of air conditioning or ventilation. They used to dig a trench just leading from their house to about 100 200 yards in a straight line away from the house. A pipe and chimney were fitted in it such that the heated air in the chimney would rise, drawing air through the cool pipe. The pipe, which was underground, cooled the air to the temperature of the earth. This cool air was let to circulate through the house to keep its temperature lower than outside.
Modern Solar Power Air Conditioner
With the development of Direct Absorption (DFA) in Japan in the 1960s, solar cooling technology took off. In 2004, BROAD Air Conditioning Co. Ltd. provided an American customer with the first solar power air conditioner. It has worked exceptionally well. Today, it is possible to cool down the heat generated by the sun by means of battery-powered air conditioners such that the battery is charged by solar energy. The solar modules charge the battery during the day, when the sun is high, while the solar power air conditioner can be used anytime.
Direct Cool Air Conditioning Inc. has created its own energy efficient DC Airco units. These solar air conditioners consume less than half power requirement of an AC input system. They are good cooling devices for small houses and cottages, industrial buildings telecommunication cabinets etc. A couple of these air conditioners can be used to cool a larger structure. Since the units operate on low voltage (2448 DC) batteries, they are ideal for replacing expensive external generators. These cooling units are available as wall-mounted devices.
Advantages of DC Airco Solar Conditioners
DC Airco Solar Conditioners consume less power and provide greater cooling. They can be used anywhere in the world because they are not frequency dependent. They do not require Genset for power supply, and do not need an inverter.
