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 reduce 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 correctly using current best installation practices. To work on a solar energy system in Rhode Island, a contractor will need both a State Electrical Contractor's License and at least a Journeyperson's License from the Department of Labor and Training.
Check TrustPilot, Google Reviews, the Better Business Bureau (BBB), and other review sites to see what past customers have to say about local solar installers. Detailed reviews on these platforms can help you assess a provider's reliability and customer service. Be wary of providers with few or mainly poor reviews.
Get free, detailed quotes from 3–5 solar companies. The quotes should describe all costs and identify the exact solar parts included. Looking at several quotes can help you find the best value for your budget.
Top-notch solar installations should include strong workmanship and performance guarantees. A workmanship guarantee covers installation defects, such as poor alignment, cracks in the panels, or poor wiring. A performance guarantee ensures a minimum energy output. Comprehensive guarantees indicate that a solar company believes in its work.
Solar energy can help decrease your energy expenses over time. Be sure to evaluate these aspects when judging the cost and value of solar panels.
The average Johnston homeowner will spend around $11,860 on a home solar system after federal tax refunds. Solar arrays in Johnston cost approximately $4,070 per kilowatt, with an average size of 4.2 kilowatts. A personalized estimate from a local solar provider will include costs for labor, preliminary work, and permit fees, and will account for your system's panel type, capacity, and size. Some homeowners prefer to lease their solar panels in order to reduce upfront costs.

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 raise your property values, qualify for tax benefits, and reduce emissions. 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. Johnston can experience long, hard winters, so we recommend installing your system in the springtime to maximize your generation for the year.
Generally speaking, your energy bills will significantly decrease after you install solar panels. This is because you're using the energy you generate for free rather than buying it from your power company. In Johnston, the average amount someone can save is $878 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system after the payback period concludes.
You might be pleasantly surprised at how short it takes to get a return on investment from your solar panels. The sun shines frequently in Johnston, meaning your payback period could last 13.5 years per 5 kW of capacity on the high end.
Net metering is a power purchasing policy that allows solar energy system owners to be compensated for the amount of energy they put back into the grid. It's available in most states and is a great way to reduce energy costs.
The answer will depend on your specific needs and goals. In most cases, monocrystalline solar panels are the most efficient for Johnston homes. However, if you're looking at a more frugal option, then you could polycrystalline or thin-film solar panels. When selecting a solar company, make sure to ask about the types of solar panels an installer offers and the benefits and drawbacks of each.
Solar energy can be more efficient than other forms of renewable energy. Their maintenance costs are low and today's systems can work in a variety of conditions.
