I requested a solar subcontractor to test the solar panels they were installing. I was told this is never done. Is this true? How do I know they are producing as advertised? I am thinking the peak output of all of the panels will never reach the installed nameplate total because the sun exposure will not be maximum on the panels simultaneously. Am I wrong to expect the panels to be tested? Alvin Hernandez July 13 2022, 1:55 am EDT
