Solar PV Panel Shading, a New Consideration for ROI?

One of the essential questions we ask with solar PV installation is “what will the return on the investment (ROI) be?” Many considerations are used to calculate a result. Researchers at the UC San Diego Jacobs School of Engineering, under the direction of professor for environmental engineering Jan Kleissl, have recently provided us with yet another consideration to incorporate into these equations — the energy efficiency benefit of solar panel shade. Using a thermal infrared camera, they were able to calculate the value of solar panel roof shading.
