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 Tennessee 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
When choosing a solar company, most homeowners or business owners wonder about the costs the most.There are several factors you should consider when trying to determine the overall cost and how much you can save, such as:
- average energy usage: The more energy your household consumes on average and the greater your current energy bills are, the more money you could save by switching to solar.
- Your income and budget: This affects what model of solar panels you can get.
- Your location: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.
- Incentives: The federal solar investment tax credit, which everyone qualifies for, lets you deduct 0 of the cost of installing your solar panel system from your federal taxes. In addition, not including incentives, you can save about $12,000 over 20 years on your energy bills.
There are many great benefits of solar despite the initial cost of installation. It can help the planet and your wallet. Plus, it can boost the value of your home, resulting in even more benefits if you decide to sell your home later.

Something that can dramatically influence your carbon footprint is your commute time and how much you drive in general. If you go solar and have an electric car, you can greatly decrease your carbon dioxide emissions by charging your car at home.Even though solar panel production releases carbon dioxide emissions, the panels make up for it by considerably reducing the amount of CO2 you would have released if you still used nonrenewable energy.

EcoWatch's Portland, TN Solar Company Rankings FAQs
Which solar power company is the best near me?

What are the best and worst things about solar power?
A few of the biggest pros are that it lowers your power bills, it’s environmentally friendly, and it can provide a good return on your investment (ROI). The most notable cons are that solar panels don’t produce electricity at night, the installation cost is pricey and solar panels aren’t always aesthetically pleasing.
Are solar panels worth it?
Solar panels call for a considerable upfront investment that will cost you several thousands of dollars, but whether or not solar panels are worth it depends on a collection of factors like the cost of electricity near you and how much direct sunlight your roof gets.
What are the different kinds of solar panels?
The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more expensive. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types can’t, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and how much energy generation you want.
