My solar installer called out my shade math, fixed my whole system output
Last fall I got a quote for 16 panels on my roof in Tucson. The sales guy swore I'd get 80% offset. My installer actually walked the yard with a shade tool and said I was getting maybe 60% because of the mesquite tree on the west side. He trimmed the tree and moved two panels to the garage roof. Now I'm at 74% offset after 5 months of data. Has anyone else had an installer push back on their own sales team's numbers?

Back in 2019 my buddy Dave had almost the same thing happen but in reverse. The sales guy lowballed him on a shaded north roof in Phoenix, then the crew chief showed up and said the whole layout was wrong, so they swapped the array to the east side and added a string of 6 panels. His offset jumped from a quoted 55% to 81% and he was just standing there wondering why the first guy even bothered. Sounds like your installer actually knew what he was doing, which feels rare these days.
