Methodology: How We Ranked the Best Solar Companies in Portland
EcoWatch's solar experts analyzed each solar company in Portland based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in Portland
Below are some the criteria we examined specifically for Connecticut solar companies
- Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
- Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
- Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
- Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
- Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
- Availability (10%): The bigger the service area, the higher the company will score.
- Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
- Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.
The Cost and Benefits of Solar in Portland
For the majority of homeowners, whether or not to invest in a solar energy system boils down to the cost. There are quite a few factors you should consider when determining the overall cost and how much you can save, such as:
- Incentives: One thing that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save a decent amount of money on your energy bills, which can give you an average of $23,000 of savings over 20 years.
- How much you spend on energy: The typical household in Portland spends around $1,100 a year on energy use alone, so you could be looking at that much in savings.
- Where your home is: This affects the average daily sunlight your roof gets, which helps determine how many panels you need.
- System size and type: Some models are more expensive than others, so the one you get can raise or lower your initial investment. Plus, the more solar panels you need to buy, the more it'll cost.
So is a solar panel system worth it? Whether you're trying to lower your electric bills, greenhouse gas emissions or both, solar panels are a solid investment for many Portland homeowners.

Solar Incentives in Portland
Because solar power is a cleaner source of energy than burning fossil fuels, there are quite a few government incentives in place to encourage people to make the switch. On top of the federal tax credit incentive, there are also some local benefits, which in almost all cases, stack with the federal incentive, so you can save even more. For detailed information about incentives that apply to you, check out our article on solar incentives.
Environmental Impact of Switching to Solar in Portland
Going solar can have a beneficial effect on the environment. But you may be curious — how much exactly can you help the environment by making the switch to solar? In a city like Portland where energy use is somewhat high, installing solar panels is a good idea for people who are worried about the state of the planet. Because solar panels don't release carbon dioxide emissions into the atmosphere when creating electricity, they're a good trade for nonrenewable energy sources. In fact, you could look forward to lowering your carbon dioxide emissions by about 40 pounds each year. For those who are worried about the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.

EcoWatch's Portland, CT Solar Company Rankings FAQs
Which solar installation company is the best in Portland?
In Portland, Phoenix Energy is the top local solar company. Our team of experts rates it 5.00 stars, so it's a good choice if you're planning on installing solar panels on your house.
What are some of the major advantages and disadvantages of going solar?
The main advantages of solar power are that it can reduce or, in some cases, 100% eradicate your electricity bills, raise the value of your home and lower your carbon footprint. The main disadvantages are that solar panels can be costly to install, you may not see as many savings if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.
How long does it take to see a return on your investment after installing solar panels?
Solar panels typically pay for themselves in about 8.2 years, but your solar payback period will vary depending on your utility costs. The higher your typical electricity bill, the faster your solar panel system will recoup your installation costs.
When is the best time of year to install solar panels?
You can install solar panels whenever it's convenient for you, but consider doing so in the winter when the demand is less. With fewer homeowners going solar, you could potentially see quicker installation times and more savings.
