Could you give a comparison on how it paid for itself in That time? I won’t lease or rent. Looked into purchase and I can’t see it being cost effective for 10 or more years.
My average bill was about $250/month with an annual usage of about 15MWHr.
System cost was 35k before subsidies and 18k after all of the federal, state and local rebates because of a very short term state program that did a 20% buy down on loan principal (wife had just gone back to school so we squeaked under the maximum for the lowest level extra subsidies)
Roof and tree work were 8k
System produces 11-12MWhr/year
SREC II payments average around $200-$250/MWhr paid quarterly for ten years.
The loan + residual electric bill was less than the bill without solar and for most months the SREC earned was enough to cover both plus some.
However I put the SREC into the loan and paid what my bill would have been if I didn't have solar to kill off the loan as fast as possible.
I don't have NG so my house is electric except for heat (oil, pellet and wood)
My bill in the last few years has gone up since I swapped to a hybrid electric water heater and got an EV. But that increased it from under $30/month average to about 70-80.
However, you need to look at your bills and get a reputable company to do a solar survey.
That survey will be very accurate but you need to ignore all of the BS that most large companies will toss at you about savings.
What you are looking at is over your net metering period does the system save you money now, not on some future inflated power cost along with "increased home value".
Without big subsidies, ten years is about what it takes unless you have really high power prices and usage.
