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:
Installing solar panels can cut your electricity costs and benefit the planet by reducing your carbon footprint. When determining whether a solar provider is the best option for you, consider these key factors.
Verify that your solar installer is properly licensed. This helps ensure that the work is done correctly using current best installation practices. The Maine Electricians' Examining Board examines professionals installing solar photovoltaic systems in the state. There are no special solar licenses; an electricians' license is all that is necessary.
Check review sites like TrustPilot, the Better Business Bureau (BBB), and Google Reviews to see feedback from past customers on local solar companies. Detailed reviews can help you assess a company's reliability and customer service. Use caution with companies that have barely any reviews or mostly negative ones.
Call 3–5 solar companies for free, itemized quotes. These quotes should describe all costs and list the solar equipment included. Reviewing multiple quotes helps you find the best option that fits your budget.
Top-notch solar installations should come with strong workmanship and performance warranties. A workmanship guarantee covers installation defects, such as poor alignment, poor wiring, or cracks in the panels. A performance warranty ensures a minimum energy output. Comprehensive warranties show that a solar company believes in its work.
Solar energy can help lower your electricity costs over time. When weighing solar panel's cost and value, be sure to consider these considerations.
Lewiston homeowners typically spend about $14,377 on home solar systems after federal tax refunds. Solar arrays in Lewiston cost approximately $3,800 per kilowatt, with the average residential solar system being 5.4 kilowatts. A personalized estimate from a local solar provider will include costs for preliminary work, permit fees, and labor, and will account for your system's panel type, capacity, and size. Some homeowners prefer to lease their solar panels 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 heater.
With home solar PV, you can recoup the cost of the system over time, lower your property's emissions, and gain additional energy independence.
Your installer can give you an estimate of what your energy bills will look like after you install solar panels. Generally, your energy bills will decrease significantly because you'll be using energy from the sun for free, instead of buying energy from the utility company. The average annual savings in Lewiston amount to $905.
Your payback period is the time to achieve an ROI on your solar panels. It will vary based on the rate your utility charges per kilowatt of power, the average sunlight in your area, and their rated capacity. Lewiston gets a moderate amount of sunlight each day, so you could expect a maximum payback period of 15.9 years per 5 kW of power depending on other factors.
With respect to taxes, the federal government offers a tax credit of up to 30% of the panels' cost. Depending on where you live, you could also claim or apply for state or property tax incentives. As for insurance, your monthly premium may be slightly higher because solar panels increase your property's value. You should speak with your accountant or insurance agent for information specific to your case.
The answer depends on your specific needs and goals. Generally speaking, monocrystalline solar panels are the most efficient for houses in Lewiston. However, if lowering cost is your top priority, then you could thin-film or polycrystalline solar panels. When selecting a solar company, make sure to ask about the types of solar panels a company offers and the benefits and drawbacks of each.
