How we worked this out
Expected: Solar API monthly
figures for your roof and
7.74 kW, part months by day
= 2,890 kWh
(3,012 - 2,890) / 2,890
= 4% above
3,012 x $0.42 x 0.90
= $1,139
0.90 is the share of your solar you use yourself with a battery. Savings are an estimate; incentives are not included. Anything within 10% of expected is normal.
How did we do?
We ask every owner the same question at 90 days. A Google review helps other Oahu homeowners pick an installer.
