Understanding Your Solar Investment
Payback Period
Most California homeowners see their solar systems pay for themselves in 12 years through electricity savings. After that, you enjoy free electricity for the remaining 15-20+ year lifespan.
Financing Options
You can pay cash, take out a solar loan, or lease your system. Cash purchases offer the best long-term savings, while loans and leases require little to no money down.
Home Value Increase
Studies show solar panels increase home value by approximately $15,000-$20,000 on average, often recovering most or all of your installation costs if you sell.
