Can I have 4 panels on flat and 4 panels on tilt behind all facing north on two different roofs equals 16
In short, that configuration is possible, as for whether it is the best config we would need more info to tell. Where are the other 8 panels?
I take it you are the property owner, not the installer. You should start by getting some quotes and see what the installation companies say.
8 on the carport and 8 on the garage beside. The installer says its not possible, I cant really understand why all on flat or tilt .thanks
It’s very likely that there are technical or physical limitations. The voltage would likely be too low if you need to put only 4 panels on one input. It might be possible with micro inverters, but there might be other reasons it won’t work.
Thanks Marty I get it now
