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. If the system is placed in service before Dec. 31, 2019, a federal tax credit of 30% of the total system cost is available.

The best solar panels are not necessarily the most expensive.his metric indicates costs relative to electrical power output. The cost of solar panels have decreased significantly over the last decade and are currently selling for under $0.70/W in industrial quantities. For homeowners, this translates to about $1.5/W.
