Make Your Own Solar Cell For Less

Probably the most expensive item is the solar cells; otherwise everything else can be purchased at your local hardware store. Many hardware stores also carry solar cells but you may be able to get a better deal by purchasing these online.

It is important to calculate the amount of power you want to generate. While it is recommended that you only build one panel to start with, once you have the knack of it you can quickly build more panels to produce more power.

Generally about 36 cells will produce 60 watts of power, though different cells may produce different amounts of solar power. Make sure you calculate the size of the solar panel needed to power the items or appliances you want.

Basically the solar panel is a very shallow box that will hold all of the solar cells in place. The depth of the box should be about 3/4ths of an inch deep and there should also be vent holes and holes for the wiring to run through. It is important to securely mount your cells and make sure they are properly wired together before permanently mounting them in the box. The sheet of glass is important as this protects the solar cells from the elements and will make your solar panel last longer.

Possibly the most time consuming step is soldering all of the cells together. All of the cells must be interconnected and both the cells and wires need to be mounted into place using screws and caulk. You also should test everything before you put the glass cover on and it is important to include a block diode so the panel does not automatically discharge at night. Make sure to place your panel is a spot that gets plenty of sun but will not get in the way.

Besides making your own panels you also need to think about what you want to do with the excess energy you will produce. Many times those that use solar power will not use all of the energy that they make. They can have their solar system connected to the main electrical grid and receive electrical credits for the energy they feed into the system.

A second option is to hook up your panel to batteries that you charge with the extra energy. This way you can still run off of your own system at night and during times of low light.
