Solar Panel Cost In 2025: It May Be Lower Than
Solar panels cost about $30,000 on average—but often pay for themselves several times over through 25-30 years of electricity savings.
According to studies by the U.S. Department of Energy, the all-in cost of a home solar panel system is between $2.74 to $3.30 per watt. 1,2,12 This figure includes the solar panels, the installation, and other expenses. Using these numbers, an average-sized 8-kilowatt residential solar system would cost between $21,900 – $26,400.
Solar battery costs vary by brand and capacity, and there are several other expenses associated with home energy storage. Here is a cost breakdown of a typical home solar battery installation: Battery: Most home solar batteries cost around $5,000 to $7,000 each, and installations can include multiple units for expanded storage capacity.
Solar panel installation costs depend on your home's size, energy needs, roof structure, and location. You can estimate around $10 to $15 per square foot of living space for solar panel installation. Keep in mind, this estimate doesn't account for tax credits or local incentives, which can significantly reduce your final cost.
Through utility bill reductions, financial incentives, and peace of mind, solar energy storage is worth it for many homeowners today. With a solar battery backup and energy independence, you can gain greater control over your home's ongoing electricity costs and carbon emissions, while staying prepared for potential grid outages.
