PV cost update (nothern NJ, near NYC):
We just installed a 9.6 kW PV system on our PHIUS-certified passivhaus in northern NJ.
I was the installer of record. I hired a licensed electrician who has an experienced PV installer crew.
It has 30 320W LG panels, a SolarEdge 10 kW inverter and 30 of their Optimizers. We used the QuickRack panel mount system – no rails.
The materials cost roughly $18,000. The installation cost around $7200.
That works out to around $2.66 per watt.
When I priced the same installation from the large installer companies, they quoted a bit more than $4 per watt.
