Solar Energy Facts - Why Solar Energy
When we are speaking about solar energy facts, people usually ask some questions. Here is the list of some frequently asked questions and the answers to this questions.
Why Solar Energy?
We all know that the cost of electricity, oil, natural gas, oil and wood are on constant rise. On a continuous basis we should ask ourselves whether our household budget can stand this constant and raising costs?
Each investment is connected with some money spending and yet there is not the end, despite investments, from day to day, year after year we pay electricity, natural gas, wood.
Of course with solar systems we must make some investments, but it is minimal compared to the others. How? So all investments are at the beginning of installation of the solar system and all ends here. We use them for the next 20, 30, 50 years or better to say forever without extra expends.
They are very small and tom some systems they even don’t exist. For systems who need to be maintained it is average of 1% per annum of the total cost of the system.
Where the solar systems can be used?
Solar systems can be used at any place on earth. Of course they are mostly used in places where it has the most sunny days, yet there are systems that are effective in cold areas.
Are they effective when it is cloudy, and when there is no sun?
Yes, this system is designed to need a little light to be efficient. Of course with the strength of the sun and the light is more even, so then the system is more effective.
Can rain, snow or wind become a problem for the solar system?
As for rain and wind the answer is certainly not. In winter especially in cold regions where snow falls in large quantities solar systems work very efficiently. How? Due to geometric position and the material of the collectors snow stays on them for a very short time.
What happens when there is no sun?
Through the day there is enough sun so hot water that is not consumed during the day can be spent at night.
So this solar energy facts speak enough for itself as the facts that solar energy is free, clean, unlimited and no one on earth has the opportunity to control it.
