New Berkeley Labs Study Finds Higher Resale Value for Solar Homes Than Previously Estimated!

New Lawrence Berkeley National Laboratory study indicates that each 1-kW increase in a solar system’s size equals an average of $5,911 higher home value.

All things being equal (via regression analysis), this value goes down by only approximately 9% per year as the system ages.

The study (http://emp.lbl.gov/sites/all/files/lbnl-6484e_0.pdf) builds on the highly influential previous study conducted by the same authors found here http://emp.lbl.gov/sites/all/files/lbnl-4476e.pdf
