@hi we have 42 panels on the roof, but due to angles and trees of course it's rare when they are all getting sun. Rated capacity is 14.618kW. I think in theory it could be higher than that since the panels themselves have a rated max of 440kW and with 42 of them that'd be 18.48kW, but I suspect they put some fudge factors in here because no one ever hits theoretical max (plus, angles, shade, clouds, losses from micro inverters, etc...).
