Using these numbers, an average-sized 8-kilowatt residential solar system would cost between $21,900 – $26,400.
According to the Solar Energy Industries Association, the average price per watt for residential solar projects was $3.27 in the first half of 2023. That is up slightly from a low of $2.92 before the pandemic, but down over 50% from the price of $6.65 per watt in 2010. Knowing the price per watt of solar is good for two things.
For example, the PPW of a 5,500 Watt system looks quite different before and after accounting for the 30% tax credit. According to the Solar Energy Industries Association, the average price per watt for residential solar projects was $3.27 in the first half of 2023.
At first glance, Quote 1 seems like the best deal because it has the lowest sticker price. However, when you calculate the PPW for each quote, you find that Quote 3 provides the most bang for your buck at $3.25 per Watt. In general, larger solar systems have a lower price per watt.
