Residential solar prices are falling lower than ever before, said marketplace operator EnergySage in its biannual solar and storage
From 2010 to 2020, solar panel prices dropped by nearly 90%, with costs per watt falling from approximately $3.86 to $0.38 globally (source: IRENA). This decline slowed in recent years but remained consistent. Between 2020 and 2025, residential solar system costs, averaging $2.50 to $3.50 per watt in 2025, decreased from $3 to $4 per watt in 2020.
In 2025, average solar panel costs continue to decrease due to advancements in technology and economies of scale. Prices vary by system type, size, and installation needs. Residential solar panels typically cost between $12,500 and $17,500 for a 5-kilowatt system.
The cost of solar panels buyers pay is also affected by the local cost of work, the type of roof, license cost, etc. In some states of the US, prices have declined due to great sunshine, like California and Texas, and more competition among solar panel installers.
Residential solar prices are falling lower than ever before, said marketplace operator EnergySage in its biannual solar and storage marketplace report. The median quoted price on its platform reached $2.50 per watt in the second half of 2024, falling 6.4% from the first half of 2024.
