Solar power is simply the conversion of light energy into electrical energy using devices attached with special materials like silicon.

Man has been late in harnessing the light energy from the radiant sun, a repository of unfathomable power. But nature has been using it for millions of years. Each of leaf of shrub, herb, or tree is a form of solar cell, producing energy for them to grow. This energy production is completed through a chemical process known as photosynthesis. This is the best example of free solar energy.

Then there are real solar panels that one can get almost free. One can get such free solar panels just for asking, for many institutions want to get rid of slightly degraded ones that can be used in households for free. Even though the panels are slightly degraded, these would work fine. Moreover, photovoltaic (PV) panels are not the only type of solar energy.

Solar heating can be set up with glass, cardboard, or wood and insulation. Free glass is available everywhere in the U.S. These can be used to make solar ovens, solar hot water heaters, and hot air heaters.

To build a solar oven costs only $9, which includes $5 for clamps and $4 for the black paint. This is a rugged way of enjoying free solar panel power. One can enjoy rebates and discounts being offered by companies selling solar products. Ordering items in bulk and allying with friends and partners would further reduce costs.

One has to tap all ideas to get the best use at cheapest price. The very idea of solar energy is to utilize the suns energy, which is available for free.
