I have received 2 bids for solar systems, third one is coming on Friday but their installs are not as clean so unless they are crazy cheap I will likely pass on them.
Both companies ended up about the same system size, 11.4 kw vs 11.52kw
I have a detached garage (12 foot walls 8/12 roof) with the rear of the roof facing south. The main house (2 story with 8/12 roof) Both the house and the garage have 200 amp panels, fed from one 360/400 meter.
Company A:
11.52 kw
36 LG Electronics LG320E1K-A5 320w panels. (facing 183*) 16 on the house 20 on the garage.
36 Enphase IQ6+ ACM micro inverters
2x Siemens 120/240 Combiner Panels
2x SolaDeck Rooftop Combiner/Junction Box
24,701.60 after the FTC (2.15 watt)
Company B
11.40
40 285W Solar World Panels (SW 285 Sunmodule Plus) 20 on the house 20 on the garage
2 SMA Sunny Boy SB Inverters 6000TL-US-22 (put both inveters in the basement of the house to keep cooler where they will be next to the main panel/meter.
21,378.42 after the FTC (1.88 watt)
Payback on company A is 12.5 years, Company B is 10.5 years
Looks like the LG Panels are better 18.6% vs 17% efficient.
I do have a couple trees that would be 30 feet to the west of the solar panels on the garage, they were just planted this year and are only 5 foot tall currently. So in 10-12 years they might start to shade a few panels at the end of the day. There is zero shading on the roof of the house.
My thoughts are to go with company B and run the garage on two circuits within the sunny boy so when I do get shade on the shop eventually it only effects 10 of the panels. But I want to hear what someone has to say that knows more than me and is not the sales man.
