How big is your system? How big is your house? Does your solar system take care of all of your electrical needs? I'm putting up a 6.1 kw system. How long is your payback time? Did you get rebates? Is your system a permanent ground mount? Did you you lean it to favor summer?
How Big PV? 12.3kW DC
How Big house? 1500 sqft
Meet needs? yes, produces about 15,500 kWh/year; house usage is about 12,000 kWh/year; system designed for excess to be available to "fuel" a future electric car.
Payback? my system was installed in 2013 and expanded in 2015. Prices have dropped a lot since then, so my payback would be irrelevant. In my area cost of a ground mount install by professional is about $3.00 - $3.50/watt.
Rebates? only rebate was the FTC. You may have other rebates/credits available. Do you have net metering available and if so, at what rate? I look at PV as along term investment, not a cost
Ground Mount? permanent
Tilt (lean)? favors spring/fall (35 degrees) and therefor favors some winter as well vs a tilt which favors summer.
