I finished getting the series string of 9 325W #solar panels mounted in their final location. Pics are from after the first 5.
It was a bit of a challenge due to the slope and the angle I wanted my panels to be at. So I needed to hobble together a level base for the last 4 which took me past sunset. It's a pretty severe grade. I had to dig some to get the right angle for the upslope panels. And a raised base several feet hight for the downslope panels.
I've still got to complete the wiring. This string has a Voc of about 400V. It's about an 80' run back to my AIO inverter. With that high a voltage and only about 10A Isc, I should be fine with the 10awg wiring. I'll measure the actual voltage drop/power loss tomorrow.
I'm very excited. The high voltage means the mppt in the inverter should wake up at first light and start providing power. The panels are in full sun there for about 8-9hrs. That's only going to grow as spring/summer approaches, and I'll have the potential for about 18kWh of solar per day.
I'll try to take a pic of the full array when the full moon comes up shortly.
The full moon is now out. This is my new 2.9kW array!

Woot. 2kW of #Solar coming in already this morning. It's hard to get a consistent voltage reading - maybe around noon. But it looks like I've only got a 6V drop in my wiring, which at about 5A is maybe 30W lost to the extra length getting to the panels.
