Buildings contribute a substantial portion of global energy consumption and greenhouse gas emissions. Solar PV is widely acknowledged as one of the most cost-effective …
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. What About Flexible Solar Panel Air Gaps?
