Building solar panels is a relatively simple matter because solar cells are modular. They are also quite small. Solar cells that are used in residential solar panels is about twice the size of a bar coaster or about four times the size of a playing card. You can fit your hands around one quite easily.
You begin building solar panels by connecting these cells in series and then connecting panels to one another. Then all that is left is to connect the solar panel array to batteries and an inverter to power your house.
Solar cells or photovoltaic cells, as we'll call them here, convert solar energy into electric energy. Now, you knew that but in order to understand the way building solar panels works, you need to know how the electricity is made.
Photons of light strike the semiconductor material on the cell's surface, usually silicon, and in so doing knock an electron loose. There are two types of silicon used to make a cell. They are both mixed with other elements which change their polarity. One type is negatively charged because it is mixed with phosphorous and the other is positively charged because it is mixed with boron. By putting together layers of silicon with different electrical charges, the incoming photons have an easier time of loosening up an electron and sending it looking for place to go.
The cells are engineered so that the electrons can only go in one direction and that direction is 'out.' So, each cell is designed to add their exiting electrons to the flow of electrons and with enough cells and enough solar energy, you have an electrical current you can work with.
See, building solar panels is not difficult but it is precise. The channels that absorb the electrons in each cell are lined up with every other channel in their particular group by means of a connecting tab, solder and flux. Once the cells are connected, a surface layer of glass, plastic or laminate (or a some combination) is layed over the top to protect them, all the moisture is removed (to avoid condensation which would interfere with the panel's efficiency) and the panels are placed into position and connected.
From there, it is a simple matter of hooking up the solar array to your house's electrical condition. In my mind, it goes without saying that you should hire a professional to do this. If you insist on doing it yourself, I believe you still need a certified electrician to examine it to insure your work is up to code. In the event of an adverse electrical event (fire), you would want your house to be up to code and in keeping with the provisions of your home owner's insurance policy. will answer an questions you might have on how to put together your own solar panels for home use.
