Frequently Asked Questions

Q: What does solar installation cost in Ontario, CA?
A: Costs depend on your system size, equipment, and energy usage. Most homeowners spend between $15,000 and $30,000 before incentives. The 30% federal tax credit can dramatically lower upfront costs—but it may expire after 2025, so now is the time to act.

Q: Can solar eliminate my utility bill?
A: In many cases, yes. A properly sized and optimized system, especially when combined with battery storage, can offset most or all of your electricity use. Keep in mind that you may still have a monthly connection fee.

Q: How long does the process take?
A: Most residential projects are completed within 4–6 weeks, including permits and inspections. We manage the entire process so you don’t have to.
