Analyzing millions of transaction-level data points from homeowners on EnergySage, it highlighted a clear milestone for solar panels: The average price had dropped 30% year-over-year in 2024. According to the report, the median quoted price of solar decreased for the third year in a row, hitting its lowest in recorded data at $2.50 per watt.
Data from the National Renewable Energy Laboratory (NREL) documented that residential solar panel installations cost about $8.70 per watt in 2010, meaning the average 6 kilowatt (kW) solar installation in 2010 cost about $52,200 before any incentives.
Let's take a look at how solar panel cost and efficiency have changed over time. Solar panels are about 60% cheaper and 40% more efficient than they were in 2010. Solar panels in 2010 cost about $8.70 per watt and were about 15% efficient. Today, solar panels cost about $3.00 per watt on average and are between 19% and 22% efficient.
According to an EnergySage report, the median quoted price of solar decreased for the third year in a row, hitting its lowest in recorded data at $2.50 per watt.
