Today's Homeowner looks at dozens of datapoints on solar companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
Adopting solar power lets homeowners lower utility bills while benefiting the planet by reducing your carbon footprint using clean energy. If you’re evaluating if you want to go solar, consider these key factors for choosing an installer.
Hiring a licensed solar installer is critical. This helps ensure that the work is done properly using current installation best practices. Solar companies in Oregon must be licensed and bonded by the Oregon Construction Contractors Board. For PV installations, each standard journeyman on the job will have at least 8,000 hours of hands-on experience and must follow continuing education requirements. Installers of solar thermal systems must be either a licensed solar heating installer and a plumbing journeyman.
Check Google Reviews, TrustPilot, the Better Business Bureau (BBB), and other review sites to see what past customers are saying about local solar providers. Detailed reviews can help you assess a provider's trustworthiness and customer service. Be wary of companies with few or mainly poor reviews.
To find a solar installer that works with your budget, get free, detailed quotes from 3–5 providers. The quotes should list all costs as well as all solar equipment included. Looking at several quotes helps you identify the option that best fits your budget.
Quality solar installations should come with comprehensive workmanship and performance guarantees. The workmanship guarantee covers any installation issues such as cracks in the panels, poor alignment, or poor wiring. The performance warranty ensures a specific energy output level. Strong warranties indicate that a solar installer trusts its installations.
Solar energy can help you lower electricity bills over time. Make sure you consider these aspects when considering the final cost and value of solar panels.
The average Ontario homeowner will spend around $9,107 on a home solar system after federal tax refunds. Solar arrays in Ontario cost roughly $3,500 per kilowatt, with an average size of 3.7 kilowatts. An estimate from a local solar provider will include costs for labor, permit fees, and preliminary work, and will account for your system's capacity, panel type, and size. Some homeowners prefer to lease solar panels in order to reduce upfront costs.
Generally speaking, a solar photovoltaic (PV) system can be used to power any household system or appliance that uses electricity. In the simplest case, you can use a solar water heating system.
With home solar energy, you can save money on your energy bill, lower your home's carbon footprint, and be better prepared if there's an outage to the local grid.
It depends on where you live and what type of panels you're installing. Since there's a moderate amount of snowfall in Ontario, your best time to get solar is in the spring and fall.
Yes, you can use home solar energy alongside conventional power sources. In many areas, solar panels are designed to supplement your existing energy sources, which means you can reap the savings and environmental benefits that come from using solar energy without having to completely switch over.
Yes, solar panels will still be able to supply you with energy during a grid outage. To ensure that your solar system can keep working during a power outage, make sure to choose a quality solar provider and look for a solar system that includes a battery backup.
Solar panels are becoming more relevant than ever for their low upkeep costs and high efficiency under a variety of conditions. Depending on how much sunlight your property receives, you may find they're the best performing source of renewable energy compared to others.
