It’s a common concern that glare from solar PV systems could affect surrounding neighbors. First, it’s important to note that any solar PV system must be approved by the homeowner’s city or county after it has been installed. If the city/county sees any potential problems, then they will work with the engineers so adjustments can be made. Installers can place the panels on homes at angles where they should not affect neighboring homes.
Solar panels are designed to capture light — not reflect it.
Solar panels reflect less light than standard home window glass, and include anti-reflective coating to help lessen any potential glare. Despite initial concerns, airports and military bases with nearby solar farms have reported that glare is a non-issue.
Glare from Photovoltaic Panels probably isn’t visible by neighbors
Even though panels are designed to limit glare, that doesn’t mean it’s impossible — it’s just unlikely.
Let’s say, just for the sake of argument, that your rooftop PV array did reflect some light. In order for that to be an issue with your neighbors, the glare would have to be visible to them.
For your neighbors to see any light reflecting from your rooftop PV array, they must be looking down on the tops of your solar panels. So their homes would need to be at least one story above your rooftop.
But that’s not all. Glare will only appear when the sun is at the right height and your neighbor is within the angle of reflection from the solar panels. With a rooftop PV array, glare is most likely going to be above the sight line of any neighboring homes, even those that are taller than yours.
If you are still worried, we suggest that you and the installer discuss possible concerns with neighbors that may be affected by the system.
