US solar module prices rose in December 2024 for the first time since last summer, driven by tariff adjustments and patent litigation uncertainty, according to Anza.
On the high end, we talked to a solar customer in Hawaii who spent $100,000 going solar. Dion in Nevada said their 10-kW system cost about $20,000, which is about the national average price for a 7-kW system. What else affects solar installation costs?
Each quarter, the National Renewable Energy Laboratory conducts the Quarterly Solar Industry Update, a presentation of technical trends within the solar industry.
It's most helpful to think about solar panels as an investment. It takes an average of 7.1 years to earn back the money you spend on installing solar panels. After that point, the electricity from your solar panels is free. Most homeowners will save $31,000 to $120,000 over 25 years with solar.
According to Infolink, the top 10 module manufacturers were responsible for 226 GW of shipments (+40% y/y) in the first half of 2024. In the first half of 2024, the United States produced 4.2 GW of PV modules—an increase of 75%, y/y—roughly evenly split between thin-film and crystalline silicon (c-Si) module technology.
Global polysilicon spot prices rose 3% from early August ($5.66/kilograms ) to early October ($5.86/kg); however, prices are still below production costs for most manufacturers.
