Solar panels silently convert light into electricity. They have no moving parts,
require little maintenance and are designed to last for many years. Solar panels
use the “photovoltaic effect”, discovered by Edmund Becquerel in 1839, to
produce electricity directly from sunlight. Solar panels work best in direct
sunshine, but they also work well even on cloudy days.
Solar panels can supply a substantial proportion of the electricity needs of a
typical household. They are often mounted on the roof or on the ground and
connected to the local electric utility, either supplying all the power directly to the
home or pumping the excess back to the utility. Apart from reducing your utility
electricity bill homeowners can often sell any surplus electricity directly back to
the utility at an attractive rate.
Solar panels are also used for commercial applications ranging from large-scale
power plants to small family-run businesses. The applications are almost
endless, but each has the same idea in mind: harnessing the power of the sun to
make clean, affordable electricity. 
Solar Energy is about the future as well as the present. With unlimited potential, Solar Energy is a clean, efficient, and sustainable form of renewable energy. But Solar
Energy is also a sound financial decision. With Solar panels powering your home, you'll see this every month when your electricity bill arrives. Finally, Solar Energy is a
green decision - you'll feel good knowing that you will leave the world a greener, better place for your children.
Today, the worldwide demand for solar photovoltaic (PV) energy is greater than supply. It is one of the fastest growing forms of renewable energy. As manufacturing
becomes more efficient, the cost of PV systems continues to drop. Prices have reduced 25 fold over the last 20 years.
Commercially, even electrical utilities are looking to Solar for a more stable cost structure. Research has shown that solar can even be effective in Northern climates. In
California, electricity rates are increasing at a rate of 6.7% per year. Solar provides a hedge against future rate hikes. And in many countries, you can sell your surplus
electricity back to the utility, generating a credit on your bill.
Not only is solar affordable, it is even more economical when you consider the alternative: the high costs of fossil fuel pollution and global warming. In recent opinion
polls, solar energy scored higher than all other forms of energy when participants were asked what type of energy is best for future generations. Photovoltaic systems
produce electric power with no carbon dioxide (CO2) emissions. The Carbon emission offset is calculated at approximately 7.5 tons of CO2 over the twenty-five year
guaranteed life of one PV module
All in all, solar photovoltaic energy generation has a very bright future indeed.
