The report indicates that the median installed price of PV systems completed in 2012 was $5.30/W for residential and small commercial systems smaller than 10 kilowatts (kW) in size and was $4.60/W for commercial systems of 100 kW or more in size.
To give you an idea of what a plain solar installation with line inverters and no additional expenses looks like, a 6kW solar system could cost approximately $25,000. If your utility company offers rebates ($2.00 per watt, for example), that amount would be deducted: $25,000 â $12,000 = $13,000.or example, if you owe the IRS $5,000 in taxes and your solar system costs $14,000 (after rebates and incentives), your tax credit of $4,200 would reduce your tax liability to $800.
