Okay, so you have taken the biggest step of all and gotten yourself some equipment and gotten some technical know-how and you think you are ready to go into the world to and become a solar installer, installing solar home heating for other home owners who have discovered the awesome benefits of having solar panels installed in their homes. This is however easier said than done. But just before you head out onto people’s roofs and start tapping the solar energy converting it to DC electricity, there are some common mistakes that you should be aware of, that many other installer have made before you.
True, solar panels often lose their efficiency as it gets hotter. Another fact that is also true is that solar thermal collectors make use of water heated from the sun to use in the house. Now you probably are thinking that you could use the water to cool off the solar panels and it would then be used to provide hot water right? No, wrong.
No one can blame you though for thinking that. Many learning about solar panels and solar energy also made this wrong conclusion. The math does not just add up. For your hot water to be sufficient for use to wash dishes and for showering, it should leave the tank at 120 degrees Fahrenheit. This is to mean that it should leave the solar panels at 130 degrees and the panels should be at 150degrees. This number are far off from the optimal temperatures of many PV solar brands at 77 degrees. As a result, you will either be showering or washing your dishes with cold water, or you will have to wait for a very long time to get the numbers from the inefficient panels.
Ii will just install a small stand-alone system that will power one or two things such as the refrigerator and the air conditioning.
Well the truth is, the refrigerator and the AC are one of the largest energy users in a home. A small system that is not connected to the grid will struggle just to power one of the consistently. If you are going to install a small stand-alone system, you should use it to power small electrical such as the lighting fixtures, the TV and the computers. Ideally, there is nothing wrong with having a small system, but tying it to the grid can help you power those large equipment and still maintain consistency.
It looks like the competition is charging an awfully high price. I just checked on the prices and they are way lower than you would expect.
It is true that the prices of the solar panels in the past few years have dropped tremendously. The installation costs however have only dropped slightly. This is because there are lots of other materials that you will require for the installation. Taking into consideration all these costs, your price will not fall far from what the competition is charging. And while you cannot work with inferior equipment, be sure that you do your math right before you make a quote.
