As of April 2026, the average solar panel system costs $2. 51/W including installation in California. 05 kW system (the average system size in California), this comes out to about $22,697 before any available incentives, though prices range from $19,292 to $26,102.
Battery storage prices have gone down a lot since 2010. In 2025, they are about $200-$400 per kWh. This is because of new lithium battery chemistries. Different places have different energy storage costs.
A single solar panel costs between $120-$315 for the equipment only, or $1,000-$1,200 when professionally installed. The final price depends on panel type, wattage, brand quality, and whether you're buying individually or as part of a larger system.
This paper presents average values of levelized costs for new generation resources as represented in the National Energy Modeling System (NEMS) for our Annual Energy Outlook 2025 (AEO2025) Reference case.
State rebates, utility demand response programs, and flexible financing options are making home batteries increasingly accessible for backup power, energy independence, and lower electricity bills.
