BENEFITS/CONTRIBUTION

Environmental Benefits: As PV generates electricity from light, PV produces no air pollution or hazardous waste. It doesn't require liquid or gaseous fuel to be transported or combusted.Economic and Social Benefits: Sunlight is free and abundant. Photovoltaic systems allows to generate electricity and store it for use when needed. It frees  from uncertainties and foreign oil dependence. This energy source is free, clean and highly reliable. PV systems are long-lasting and require little maintenance. The benefits of Photovoltaics far outweigh the initial cost the systems.

Solar cells make absolutely no noise at all. They do not make a single peep while extracting useful energy from the sun. On the other hand, the giant machines utilized for pumping oil are extremely noisy and therefore very impractical. Solar energy creates absolutely no pollution. This is perhaps the most important advantage that makes solar energy so much more practical than oil. Oil burning releases harmful greenhouses gases, carcinogens and carbon dioxide into the precious air. Very little maintenance is required to keep solar cells running. There are no moving parts in a solar cell, which makes it impossible to really hurt them. Solar cells tend to last a good long time with only an annual cleaning to worry about. Solar panels and solar lighting may seem quite expensive at first purchase it, but in the long run use will find that saving quite a great deal of money. After all, it does not cost anything to harness the power of the sun. Unfortunately, paying for oil is an expensive prospect and the cost is still rising consistently. Solar powered panels and products are typically extremely easy to install. Wires, cords and power sources are not needed at all, making this an easy prospect to employ. Solar power technology is improving consistently over time, as people begin to understand all of the benefits offered by this incredible technology. As our oil reserves decline, it is important to turn to alternative sources for energy. Solar energy is a completely renewable resource.

Combined photovoltaic and thermoelectric source are an almost miraculous way of producing electricity directly from sun without concern for energy supply or environment harm.
