Since your monthly electric bill is $500, you should first be as energy efficient as possible before going solar. Make sure your HVAC, air-conditioning and major appliances are efficient Energy Star rated. You might also install a solar attic fan to reduce your heating and cooling costs. We have some great prices on quality solar attic fans.

*Note: These are current solar price estimates as of February 2012, amounts may vary based on your location and installation factors. The 25 year utility cost includes a conservative 2.5% annual electricity price inflation rate. Inflation may vary by utility. According to the Department of Energy, the national average for annual electric utility price inflation is 4%, while some states are as high as 7% or 8% annual inflation. The estimated kWh produced per month includes 230 watt or 250 watt solar panels and 5 sun hours per day. Results may vary based on location and installation factors.
