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:
Putting solar panels on your roof could cut your electricity payments while benefiting the planet by reducing your carbon footprint through renewable energy use. Key considerations when researching local solar installers are as follows.
It's important to hire a licensed solar installer. This ensures that the work is done properly using current installation best practices. The Maine Electricians' Examining Board certifies professionals installing solar photovoltaic systems in the state. There aren't any special solar licenses; only an electricians' license is necessary.
Look at review platforms such as TrustPilot, Google Reviews, and the Better Business Bureau (BBB) to find out what previous customers say about local solar installers. Reviews can give you an idea of a company’s trustworthiness and customer service. Be cautious of companies with no reviews or with predominantly negative feedback.
Call 3–5 solar companies for free, itemized quotes. These quotes should explain all costs and specify the solar equipment included. Reviewing multiple quotes helps identify the best option that fits your budget.
Top-notch solar installations should come with strong workmanship and performance warranties. A workmanship warranty covers installation issues, such as poor wiring, cracks in the panels, or poor alignment. A performance warranty guarantees a minimum energy output. Comprehensive guarantees indicate that a solar company believes in its work.
Going solar can help lower your electric bills over time. When considering the total price and value of solar panels, be sure to consider these factors.
The cost of home solar panels in Lisbon varies depending on several factors, including the area and generating capacity of your panel array and the type of solar technology being used. Generally speaking, a typical solar energy system costs $3,800 per kilowatt, not including labor, preliminary work, or permit fees. Most solar systems in Lisbon are 5.4 kilowatts, and the typical Lisbon homeowners spends $14,377 after accounting for federal tax refunds. Some homeowners may prefer to lease solar panels and 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 heater.
With home solar PV, 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 your home's location and the kind of panels you plan to use. Lisbon can experience long, hard winters, so we recommend installing your system in the spring months to maximize your generation for the year.
Yes, it's possible to use home solar energy alongside conventional power sources. In many areas, solar panels are designed to supplement your existing energy sources, meaning that you can reap the environmental benefits and savings that come from using solar energy without having to completely switch over.
Your payback period is the time to achieve an ROI on 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. Lisbon 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.
Your recommended maintenance will vary based on the type of solar panels you have. At a minimum, you should clean and inspect each panel once per season. Your solar contractor might offer comprehensive plans where they'll do the maintenance for you.
Net metering is a type of "power purchase agreement." If your utility or state offers net metering, you can sell the solar energy you don't use to the grid. In return, they'll give you a credit on your power bill.
