Solar Energy

In simple terms, and as the name suggests, solar energy is the energy produced by the earth's closest star, the sun. The sun creates energy through a thermonuclear process, which produces both heat and electromagnetic radiation in the form of visible light, infrared light, and ultra-violet (UV) radiation.

Only a fraction of that radiation reaches the earth, the rest goes into space, but it is more than enough to provide all of our power needs several times over. Solar energy can be used in two different ways: as a heat source and as an electrical source. The process of converting the sun’s energy into electricity is called photovoltaic (PV).

How Solar Works

Solar systems work when sunlight strikes a solar photovoltaic module (called a solar panel, or PV panel) and excites electrons trapped in the silicon solar cell. The electrons exit through wires on the back of the solar panel and enter your house through your circuit breaker and electric meter. Since solar system has no moving parts, and no mechanical wear and tear, it will last for many years with only minimal maintenance.

The following illustrates how solar works on your rooftop.

Benefits

The impacts of global warming have led to an emergence of public awareness about the importance of renewable energy. The solar energy is reasonably predictable throughout the year. Solar PV produces electricity directly from sun rays and provides numerous environmental benefits for our next generation. Please check out the Government Incentives session for economic benefits.
