Here is a ground mount in Maine. Schletterer racks, 215 azimuth 30 tilt. 2x12x280 Hyundai panels, SE6000 inverter
Data http://www.pvoutput.org/list.jsp?userid=37844 I have just recently got PVwatts pulling SE data.
My roof has 50 year metal shingles https://www.tamko.com/ResidentialRoo...WorksAstonWood one installer wanted to use L brackets with 5 lag bolts for each bracket, through the metal shingles. That would potentially be hundreds of penetrations. Another installer recommended ground mount as they would not install on my roof.
