How To Choose a Solar Company

Putting solar panels on your roof could lower your electricity payments while helping the environment by reducing your carbon footprint through renewable energy use. Key considerations when looking at local solar installers are as follows.

Check Licensing

Verify that your solar installer is properly licensed. This ensures that the work is done properly using the most up-to-date installation methods. There are five specific classifications of solar contracting licenses in California: boilers, PV electrical, HVAC, thermal, and pool heating. For a contractor to earn a license, a contractor must complete a highly comprehensive educational series, gain four years of experience as an apprentice or journeyman, and pass written exams.

Read Customer Reviews

Check review sites like Google Reviews, the Better Business Bureau (BBB), and TrustPilot to see feedback from past customers on local solar companies. Detailed reviews can help you evaluate a company's dependability and customer service. Use caution with companies that have very few reviews or mostly negative ones.

Compare Multiple Quotes

Call three to five solar companies for free, itemized quotes. The quotes should outline all costs and specify the solar equipment included. Reviewing multiple quotes helps identify the option that aligns with your budget.

Ask About the Warranty

High-quality solar installations should include robust workmanship and performance guarantees. The workmanship warranty covers any installation issues like cracks in the panels, poor alignment, or poor wiring. The output guarantee ensures an energy generation baseline. Strong guarantees reflect a solar provider's faith in its installations.

Evaluate Financing and Incentives

Solar power can help decrease your electricity costs long-term. When weighing solar panel's cost and value, be sure to factor in these considerations.

  • Look into utility rebates: More discounts might be available from utility companies looking to encourage homeowners to install solar panels. Contact your local utility provider to learn rebate values and eligibility rules, so you can determine your possible savings.
  • Research federal and state tax credits: A 26% federal tax credit for the full solar system cost is available through 2032. Many states provide incentives, too. The credits can result in substantial savings for solar buyers.
  • Compare system purchase options: Solar panels can be purchased upfront or financed over time with loans or leases. Check key financing details like payment schedule, fees, annual percentage rate (APR), and ownership implications when choosing to finance solar panels.

Cost of Solar Installation in Ontario

Ontario homeowners typically spend about $6,973 on home solar systems after federal tax refunds. Solar arrays in Ontario cost roughly $3,470 per kilowatt, with the average residential solar system being 2.9 kilowatts. An estimate from a local solar provider will include costs for preliminary work, permit fees, and labor, and will account for your system's size, capacity, and panel type. Some homeowners prefer to lease solar panels to reduce upfront costs.

Frequently Asked Questions About Solar in Ontario, CA

Generally speaking, a solar photovoltaic (PV) system can be used to power any household appliance or system that uses electricity. In the simplest case, you can use a solar water heating system.

There are a number of advantages of home solar energy. You can reduce emissions, save money, and qualify for tax benefits. With the right storage equipment, solar panels can also provide you with further energy independence and offer some protection from power outages.

It depends on where you live and what type of panels you're installing. With the winter months in California being very mild, you have a lengthy window to install your panels, though they won't hit peak performance until summer arrives.

Your payback period is the time to earn a net profit from your solar panels. It will vary based on the average sunlight in your area, their rated capacity, and the rate your utility charges per kilowatt of power. Ontario has extremely high daily sunlight levels, so you could recoup your investment in as little as 9.3 years per 5 kW of rated capacity.

Yes. Solar panels are independent of the Ontario grid and will continue to generate power even if the grid is having problems. Keep in mind, however, that a solar system won't take you through a nighttime outage if you don't have a storage system. Your contractor can discuss some economical options to keep your home's power access reliable through the worst conditions, including battery backups or an emergency generator.

Solar panels are on par with other forms of renewable energy. Their maintenance costs are low and today's systems can stand up to the worst conditions.
