What are solar panels made up of?
I mean like bread is made of wheat, what are solar panels made up of?
How are they manufactured?
Sam Deane answers:
Hey Zeus, I have to assume you are talking about the solar electric, or photovoltiac type of panel, they are the most common and are used to make electricity directly from the sun. They are made up of basically 3 things, pure silicone, sliced in thin slices from solid ingots, acrylic for the glass covering, and aluminum for the frames. The thin silicone slices, or “wafers,” are doped in two different chemicals, boron and phosphorous. When the two different wafers are glued together with a conductive epoxy, and put in the sun, the incoming photons from the sun strike the wafers and force electrons from one wafer onto the other. This is referred to as the, “photovoltiac effect,” and it creates 1/2 of a volt between the two wafers. By connecting a suitable number of these pairs of wafers together, we can generate any voltage we need by simply putting the panel in the sun. Take care Zeus, Rudydoo

My nine year old is doing a project for school and needs to know what household objects can you use for a solar panel?

Donna asks…
What are solar panels made of and what are there advantages and disadvantages?
Sam Deane answers:
They’re made of wafers of crystalline silicon, and attached wires.
They make pollution free electricity.
Dis- not so good under cloudy skies, expensive.
Maria asks…
what are solar panels made off?
This is not a question of how they are made, but the actual materials they are made with and how do you dispose of solar panels that are no longer usable? Are they dangerous to dispose, do they breakdown easily?
I am especially curious about polymer solar panels. Because I know polymer is plastic, and plastic is usually made of oil so wouldn’t that make polymer solar panels not environmentally friendly?
Please enlighten me, I’m really curious.
Sam Deane answers:
How to make a solar generator from scratch is less expensive but more labour intensive. You will need raw copper sheeting and it is available at hardware stores and then a heat source. The copper must be heated for at least a half hour for a chemical reaction that produces copper oxide. When the copper sheeting is cold you combine it with another non-oxidized copper sheet of the same size. You then add a salt-water solution and then all the components is enclosed in a durable glass panel. You have a low voltage panel now. It depends on how much power you want on the number of panels you will have to make.
