version would work. My installer was none too careful about what was South, the west end of the S lot
line is 36 feet farther south than the east end. It was 2 years before the trash was cleaned up, I found
the stakes, and marked out the area in 100 foot squares. So only the 2018 construct is precise, but the
other facing and elevation angles can be measured out. All my E-W facing panels are mounted on a
10% grade, one end being nearly 7 feet higher than the other. I believe that is irrelevant, long as the
elevation angle is measured on a true vertical angle.
There are at least 4 different brands of panels, either 250W 60 cell or 275W 72 cell. All that could be
tracked down, along with time in service. Inverters are a pair of Fronius IG Plus 7.5KW running since
May 2013, increased loading in Nov 2013 and again in Mar 2018. Much of the current setup is slated
to be upgraded, if the foundation gets dug.
With good weather for a couple days, I will probably be working all out on the 225 foot trench, maybe
can pick up the missing numbers in unfavorable weather. If you stop by, I have extra shovels. The
trencher is working, but tough going here with all the rocks. Bruce Roe
