Solar panels can definitely act as insulation! In fact, a study conducted by researchers at UC San Diego Jacobs School of Engineering found that solar panels can reduce the amount of heat reaching the roof by an incredible 38%.
The gap between solar panel rows should be around five to six inches, but it is also recommended that you leave one to three feet of space between every second or third row. This is because maintenance workers need enough room to get on the roof and make repairs whenever necessary.
Key specifications to consider when evaluating solar panels are the wattage or power rating, efficiency percentage, operating voltage, current output, and the temperature coefficient that indicates how the panel's performance is affected by temperature changes.
While it varies from home to home, US households typically need between 10 and 20 solar panels to fully offset how much electricity they use throughout the year.
