For example, the total average cost of an installed residential PV system under the California Solar Initiative is $8.70 per Watt (including installation, as of January 2011).or example, using the Clean Power Estimator, a south-facing three-kilowatt system installed at a 30-degree angle on a single-family home with a utility bill of $180 per month in San Francisco would cost a customer an estimated $19,282 with a payback period of 12 years.
The cost of a solar electric system is measured in dollars per watt. The average cost for a residential system is currently $3-5 per watt. That means the average 5-kW residential system will cost $15,000-$25,000, prior to tax credits or incentives. A one-time âResidential Renewable Energyâ federal investment tax credit (ITC) is available for residential solar PV systems. The credit is based on a percentage of the total solar PV system cost.
