Retired engineer but newbie with solar. Would appreciated any help/advice from those with more knowledge/experience.
Am considering buying a pallet of used SunPower 435w panels and am researching the components needed to build a residential grid-tie system to offset costs. Prefer to avoid batteries altogether. I'd like to keep it simple but happy to pay for reliability.
We typically use 1200 kwh per month. So thinking a system somewhere between 5kw and 7.5kw would work.
I'm in the Virgin Islands, so single phase 60hz. Good roof area facing south and have space for 1 row of 10 panels and another of 6 panels. Am thinking maybe 3 stings of 5 panels, but may have to go for 3 strings of 4 panels because of inverter input voltage limit.
Like the look of the SolarEdge Inverters ideally with optimizers, but I can't locate a single phase optimizer that can handle the 435w panel VOC of 85.6v.
Does anyone have any experience with these 128 cell commercial grade panels? (Panel specs attached)
Thanks
Peter
