The different materials used to make solar panels frame materials. Backing materials are a key component in the design of a solar panel. Their main function is to. The silicon used to make the vast majority of today s photovoltaic cells is abundant but a silicon based solar cell requires a lot of energy input in its manufacturing process said.

Afterward i took the panel outside in the sun to test the voltage current of the whole panel to make sure i was getting 18 volts and 3 5 amps in an open circuit and short circuit. The manufacturingprocess purifying the silicon making single crystal silicon making silicon wafers doping placing electrical contacts the anti reflective coating encapsulating the cell. This is also seen in part 7 and part 8 of the video. Even ten years ago this study said it takes about 2 years of energy generation to pay back the energy used to make the solar panel.

If you had one polycrystalline and one monocrystalline solar panel both rated 220 watt they would generate the same amount of electricity but the one made of monocrystalline silicon would take up less space. In 1956 gordon pearson darryl chapin and cal fuller first used silicon to produce a solar cell achieving a much improved efficiency of 4 and introducing silicon as a key material in solar energy production. Then it makes energy with no energy cost at all for the rest of its life. So a solar panel will make many times more energy than it takes to make it.

Here are the common parts of a solar panel. Monocrystalline solar panels are slightly more expensive but also slightly more space efficient. To help give the inside of the solar panel a nicer look i used 2 strips of wiremold and ran the wires inside those. The solar panels themselves are the key elements of a solar power system.

The components of a home solar power system include.
