House sale value premium after solar panels installation

How much, according to the following trustworthy study, is the increase of the value of your house after adding solar panels?

The Office of Energy Efficiency and Renewable Energy (Solar Energy Technologies Office) of the U.S. Department of Energy under Contract No. DE-AC02-05CH11231 has supported the publication of the study:

"Appraising Into The Sun"

This study is the corner stone of the calculations of the Return On Investment (ROI) for rooftop solar panels installation.

Type "1002778. pdf" in Google search and go to table 6 (for my selected location, Gambrills, MD) you will find " Premium as a % of sale price of 2.49% of $535,000 sale price"

The value of this house will increase by $13,321 after installation of rooftop solar panels.

This is a DOWNPAYMENT on the ownership cost of solar installations similar to tax credits and other incentives.

You will be surprised by the result of the calculations of the ROI of solar installations in the forthcoming posts.
