The cost of a solar system depends mainly on its size, which is driven by how much electricity you use, plus the equipment and the complexity of your roof.
What shapes the final number:
- System size. Larger systems cost more up front but offset more of your bill.
- Equipment. Panel and inverter choices, and whether you add battery storage.
- Incentives. Tax credits and local incentives can substantially lower the net cost. See solar incentives and tax credits.
- How you pay. Paying cash, financing with a loan or other options change the up-front amount. See financing options.
