Solar panels in Louisiana
NREL's PVWatts model puts a south-facing, 20° roof array in New Orleans at about 1,479 kWh per kW of panels a year (5.3 peak sun hours a day). Covering the average US home's 899 kWh a month takes about 7.3 kW, or 19 panels of 400 W; at 13.35¢/kWh that power is worth about $1,501 a year. Output peaks in May (149 kWh per kW) and bottoms out in Jan (93). 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 — 4.8 times Louisiana's grid price. Generators are for outages, not savings. Compare with the fuel consumption calculator.
