Solar panels use photovoltaic cells (solar cells) to convert sunlight into electricity. According to the National Renewable Energy Laboratory (NREL), the PV effect was discovered in 1954 when scientists at Bell Telephone discovered that silicon (an element found in sand) created an electrical charge when exposed to sunlight.
Solar panel cells usually consist of monocrystilline or polycrystalline cells. Monocrystilline cells are typically part of more expensive panels and convert more sunlight into electricity than polycrystalline cells. Spending a little more on your solar panel can pay off in the long run.
Sunshine is a solar panel's best friend. All you need are sun rays and the electricity will begin to flow. Since the amount of sunlight varies around the world, it is essential to know many hours of good peak hours of sunlight your area receives. That's why position is key when mounting panels on the roof. If positioned in a good location (during the winter or summer months), you should have no problems. Many governments are now offering solar panel rebates to help individuals who invest in solar power.
Modern-day living seems to go hand and hand with electricity. Solar panels produce no greenhouse emissions, so they assist in slowing down global warming. It's a great way to utilize clean renewable energy. At a time where everyone is opting to go green to conserve planet Earth, you can rest assured that by using solar panels you would greatly help to reduce your carbon footprint.
The world need more clean energy resources. In remote locations of the world, people can use solar panels to supply solar energy to places where electricity is scarce. Since the maintenance is low, a simple wipe down is all they really need to prevent buildup of dust and grime. If more people and governments all over the world begin to invest in the use of solar panels, the Earth would begin to become a much cleaner planet.
