Solar power system absorbs the sunlight and then converts it into electricity that we can use. Every second, the sun sends about 42 trillion kilocalories of energy to the Earth. If we could convert 100% of this solar energy into electricity, we could create one year’s worth of power for the entire planet in a single hour.
There is chance of the end of reserves of fossil fuels such as petroleum and coal which are under earth crust. Moreover this burning of fossil fuels contribute to global warming, green house effect and climate change. So the use of solar energy is the better option and also renewable and green energy.
In contrast, as long as the sun exists, we can harness its energy here on Earth; and because solar power emits no carbon dioxide, it is an effective solution to natural resource depletion and climate change — problems that are becoming more serious every year.
We can convert the solar energy directly to the electricity with the help of solar cells. Every day the sunlight hits our roof’s solar panel with photons. The solar panel converts those photons into electrons of direct current ("DC") electricity. The electrons flow out of the solar panel and into an inverter and other electrical safety devices. The inverter converts that "DC" power (commonly used in batteries) into alternating current or "AC" power. AC power is the kind of electrical that your television, computer, and toasters use when plugged into the wall outlet.
There is a meter which tracks how much energy your solar power system generates. Any solar energy that you do not use simultaneous with production will go back into the electrical grid through the meter. In some situation when the day is cloudy then you can consume the electricity normally through grid.
From all the benefits of solar power system the most important is it is absolutely renewable source of energy. And the thing is it is available in every corner of world and every day. We cannot run out from this source of energy as from other source of energy.
Since your energy needs would be meet by electricity created by Solar power system then your bills will drop. How much you will save depends on the size of your Solar power system. Moreover, not only will you be saving on the electricity bill, but if you generate more electricity than you use, the surplus will be exported back to the grid and you will receive bonus payments for that amount which would be greatly beneficial to you.
Solar power system does not require much maintenance. Only we have to keep it clean. Cleaning it couple of times will do the job. Generally, most reliable Solar power system manufacturers give 20-25 years of warranty.
We know that the majority of homeowners choose to go solar because it makes good sense from a financial point of view. That being said, the environmental benefits are also clearly worth mentioning.
The U.S. places second in the world in annual carbon dioxide emissions at 17.9%, right behind China. You can go a long way in lowering your carbon footprint by replacing utility power with clean electricity from solar panels.
