Michael Davis, an astronomer from Arizona, has found an inexpensive way to produce electricity that can be used to power a home. He found some damaged and blemished solar cells on eBay, and decided to use them to construct his own solar panels.

Most of us understand the benefits of using the sun to produce electricity. Sunlight is available for free and there is less harm to the environment. Up until now, the main stumbling block has been the cost of solar panels which contain electricity-producing photovoltaic (PV) cells.

In searching for a source of PV cells, Michael found some on eBay that were damaged or blemished. Here is what he learned when he used them to construct his own solar-powered electric generator:

* Less then perfect cells can still perform efficiently.

* They are just a fraction of the cost of new cells.

* They can be purchased on eBay or from other sources.

How To Construct A Solar Panel

If you are handy with tools, you can construct your own solar-powered generator following these basic steps:

1. Determine Your Requirements

First, decide whether you want enough electricity for your entire home or just a few appliance. I would suggest starting with a small system and expanding it over time.

2. Locate And Purchase Photovoltaic Cells

eBay is a good source for used or blemished cells, but you might also ask the cell manufacturers or contractors that install panels if they have used or damaged units. Be aware that all PV cells are not alike and have different performance ratings

3. Solder The Cells Together

The cells must all be connected together. They may have tabs that simplify this or you will have to wire them together. You will likely need to do some soldering.

4. Construct Panels To Hold The Cells.

Depending on the size of your system, a single panel may be all you need, but you’ll likely need several. They must be large enough to hold your cell assembly, but hopefully not so large that you can’t carry them up to your roof, or wherever you will be mounting them. Panels can be connected together to form a system of virtually unlimited capacity.

5. Assemble, Test, And Mount The Panels

Assemble your solar panel by placing the PV cells inside the panel box. Run wires out through holes in the box. It’s best to cover the unit with Plexiglas. Then test the electrical output in sunlight.

6. Mount The Panels

Select a location for your panels that is never in the shade. If you live north of the equator, face the panels southward. If installed on the roof, make sure they are flashed properly to avoid roof leaks.

7.Hook Your Panels Up To Your House Wiring.

To complete your project, you’ll need to run wires from your panels to your home’s electrical system. Here are some additional items you will need:

* Inverter – this device converts power from DC to AC

* Emergency shut-off switches

* System monitor and Battery back-up (optional)

You can start out small and expand your solar power system over time. If you generate excess power, you can even sell it to the local power company and start seeing a profit.
