If after installing solar panels you find that you are producing more energy than you need, you can sell the extra energy that you produce back to the electric company. This method will help you recoup the cost of your solar energy system's installation and parts. Additionally, after you have recovered your costs, you will be making a profit.
It is important to know that about the two main types of photo-voltaic solar panels. The less expensive types are the poly-crystalline panels, but they also are less effective than the mono-crystalline panels. You should invest in a very efficient solar energy system if that is something you can afford.
Do not let a salesperson pressure you into purchasing solar panels. A solar energy system is an important investment and you should take the time to compare your different options. If a vendor feels the need to pressure you, they might not be confident about the quality of their products.
Many solar systems require little or no maintenance to operate smoothly throughout the year, but you should have them service occasionally. Dirt, leaves and dust can accumulate and reduce the amount of power that your system can produce. Have a licensed installer come out regularly to preform maintenance on your system.
If you have a pool, don't even think of heating it any other way than solar! This is easily the most efficient use of solar power there is and it will save you a bundle. Solar heating systems cost about the same or less than conventional systems and basically operate themselves so stop wasting your money doing it the old-fashioned way!
