Solar panels in Connecticut
NREL's PVWatts model puts a south-facing, 20° roof array in Hartford at about 1,252 kWh per kW of panels a year (4.6 peak sun hours a day). Covering the average US home's 899 kWh a month takes about 8.6 kW, or 22 panels of 400 W; at 27.97¢/kWh that power is worth about $3,082 a year. Output peaks in Jul (137 kWh per kW) and bottoms out in Dec (61). Run your own numbers in the solar panel calculator.
Running backup power instead
A 7.5 kW portable generator at half load burns about 0.75 gallons of gasoline an hour, roughly 3.75 kWh. At $3.20 a gallon that is about 64¢ per kWh — 2.3 times Connecticut's grid price. Generators are for outages, not savings. Compare with the fuel consumption calculator.
