22 panels weren't making power.
Two groups of 11 panels were warmer than everything around them. In daylight they look exactly like the rest.
Those panels are likely disconnected from the inverter. Have the installer check those two circuits first.
We find the solar panels that aren't producing and the wet roof areas you can't see from the ground, so you can fix them before they cost you more.

One small square on one panel was much hotter than anything else on the roof. It showed up from every angle we flew, so it isn't a reflection.
A hot spot like this gets worse over time. Have the installer look at that panel while it's still under warranty.

We flew the roof for the City of Leominster Veterans' Services: once before sunset for photos, and again after sunset with the thermal camera.
They got a plain-English report showing where water may be getting in, starting with the porch roof, and what to have their roofer check.
“Thank you for this invaluable information.”

After sunset, part of the porch roof stayed warm while the rest cooled off. Wet insulation holds heat like that.
Have a roofer take a small core sample there to confirm. Fixing it now costs far less than a new roof later.
Find the panels that aren't producing, on residences, businesses and solar farms.
Find wet spots under the roof before they turn into leaks.
Find hot connections in electrical gear before they fail.
We'll look it up, check the airspace and send you a price. No one needs to be on site.
