If you choose the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. On the other hand, higher efficiency could save you more over time on your electric bills. Additionally, add-on products, such as solar batteries, can bump up your total well above the Portland average.
Solar Financing Terms
For some homeowners, paying for solar panels out of pocket can be a challenge. Solar loans are provided by most installers in Portland, which can reduce, or in some cases eliminate, your upfront costs to make solar more affordable.When considering your overall cost, you should also calculate the interest you’ll pay if you opt for a solar loan.

EcoWatch's Portland, ME Solar Cost FAQs
How much does it cost to install solar panels in Portland?
The average cost of solar panels in Portland is about $19,000 for a 5-kW system and $38,000 for a 10-kW system before the ITC, but the actual cost will depend on stuff such as the kind of solar panels you want, what size system you need and how much energy you consume.
Is cost the most important thing to think about when buying solar panels?
The initial cost is a very important factor to consider, but whether it’s the most important for you depends on your reasons for going solar. In cities where rooftop space is limited, efficiency can be more important than the cost. Other factors that are important to be mindful of are the quality and durability of your solar panels.
Can solar panels completely eradicate my electricity bills?
It is possible to eliminate your electricity bills with solar panels, but for most homeowners in Portland, that will require at least a 10-kW system. Not all homes will have the roof space for that size system, so you’ll want to contact a local solar installer to see how many panels can fit on your roof.
How often do you have to replace solar panels?
On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger amount of energy production.
