The average solar energy system size in the U.S is approximately 5 kilowatts (kW). Based on the average price of $3.36/watt, a 5kW system would cost $11,760 after tax credits. Below are some average 2015 quotes for other solar energy systems by size: 6kW solar energy system cost: $15,000. 8kW solar energy system cost: $20,000.
The average cost of solar panels has gone from $76.67/watt in 1977 to just $0.698/watt today (the second figure is according to PVinsights, and is even lower than the 2013 projected price in the chart below).Data Source: Bloomberg New Energy Finance (BNEF).Chart Source: Unknown.he average cost of solar panels has gone from $76.67/watt in 1977 to just $0.698/watt today (the second figure is according to PVinsights, and is even lower than the 2013 projected price in the chart below).
