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.
