The Working of Solar Panels for Energy
Photovoltaic modules are becoming very popular these days as they are very efficient and simple to use. Electricity is produced by these solar panels when sunlight is converted into energy. Silicons in the solar cells convert photons into electrons. When the photons from sunlight hit the solar cells, the silicons absorb the energy displacing electrons. The electrons are attracted to a magnetic field. This magnetic field is created by metal contacts that are charged positively and negatively and found above and at the base of the solar cells. This produces DC electricity or direct current. The DC power is converted to AC or alternating current with the help of an inverter. The AC power helps to run all electrical appliances at home. This is how a photovoltaic solar panel produces electricity.
The Modern Solar Panel Technology
The advancements made in solar panel know-how are commendable. The fact that these panels have become affordable is because of extensive research and growth in this field. It is important to note that whatever developments are made now, the use of photovoltaic modules will continue as the main component in the future. Different types of photovoltaic panels that are more efficient and cheaper are being developed.
Another area of research and development is in the concentration technology. Specific equipment is employed for using a greater quantity of sunlight instead of using only the sunlight that falls on the solar panels. With all this progress, it is definite that solar power should be used by all not only to save on power but also for clean energy.
What you should know before Installing Solar Panels
A solar panel will work even in places with less sunlight as the photovoltaic cells are efficient enough to produce a steady flow of power. Before installing check if your roof is strong enough to hold the equipment. According to the USDE or U.S Department of Energy, for solar power to be lucrative, 40% of your power requirement should be met.
Whether for home or office use, one solar panels is insufficient to meet your energy requirements. To regulate the electricity, a good control panel is also required. If you opt for an off-grid system, rechargeable batteries are needed to store power. The U.S Federal government encourages residents to go for solar power by providing subsidies for installation or some other incentive.
