6 Common Mistakes Solar PV Installers Make


Comly Wilson, Associate with CleanEdison, a solar installation training provider, offers her tips to remedy 6 common mistakes solar PV installers make when setting up new Solar Mistakes Fotolia_Marco2811photovoltaic systems. 

Okay, so you’ve got some equipment, you’ve got some know-how and you are ready to get out there and become a solar installer. Sounds easy enough, I mean everyone is talking about it, right? Well yes, but before you start going onto people’s roofs and drawing high-voltage DC electricity from the sun, you should know the common mistakes that others (many others) have made before you. This is by no means a list of all the questions you will have, or problems you will run into, but it should help dispel some misconceptions you may have about solar energy.

Mistake #1 

I learned that solar PV panels lose their efficiency as they get hotter, but I also know that solar thermal collectors use water heated by the sun for use in the home. I could just use the water to cool the PV panels and then it would be heated for hot water use. I’m a genius! 

The Truth:

I don’t blame anyone for thinking this. I know I did at first, as I’m sure 90 percent of people learning about solar energy have. The truth is that the math doesn’t work out. In order for your hot water to be sufficient for uses such a showering and washing dishes, it should be in the tank at 120 degrees Fahrenheit, which means it would have to be 130 degrees on the roof and the solar panels would have to be 140 -150 degrees. This is a far cry from the optimal temperature of most solar PV brands at 77 degrees. So, either you’ll be showering in cold water or you’ll be waiting an awfully long time to get a return on those inefficient solar panels (which you’ll need to combat the 140 degree temperature outside). 

Mistake #2 

I’m just going to install a small stand alone system to power one or two things, like the air conditioning and refrigerator.
