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.
Step 2: Estimate your cost per Watt installed. Hint: If solar is popular in your state (CA, CO, NJ) and you have asphalt or composite shingles, then use $4-$6/W. If solar is less popular in your state (VA, TX, MI) and you have a tile roof, then use $6-$8/W.If youâre unsure, $5.5/W is about the National average.his calculator assumes no State or Utility rebate. Go to www.dsireusa.org to see if your area offers solar incentives. If it does, subtract it first from the Estimated System Cost. This is your total cost of installation. Then calculate the Fed Tax credit by multiplying the result by 30% (0.3).
