I used Longi all-black panels for the roof setup and mounted them on proper rails, bolted down—massive upgrade over my old sketchy panels. With four panels feeding two inverters, I could cover my phantom drain on sunny days and make a real dent even when it was cloudy. The big thing is installing them properly so you’re not gambling with your roof (or your safety).
