According to the Solar Energy Industries Association (SEIA) and Greentech Media Research (GTM), the average price for a residential solar installation is just below $3.00/watt. That means if you purchase a medium sized residential system of 5 kW, it would cost about $15,000. This does not factor in the federal tax credit or any additional incentives.
There are several factors that impact how much your solar system will cost. These include the size of your system and the equipment you use. Local factors will also influence the cost of solar. These factors include costs for permitting and the local cost of labor.
