Solar can be a big investment. Our goal is to highlight companies best equipped to meet most Portlanders’ energy needs.
We took a data-driven approach, informed by expert editors and considering the Mediterranean-type climate, to choose the best solar companies in Portland, Oregon, based on the following key features and respective weightings:

We’ve talked to dozens of Oregonians who have already gone through the solar panel installation process. Here’s what Portland residents should look for when choosing a solar panel installation company. We’ll also touch on overall costs and ways to save with government incentives.
A typical residential solar panel installation costs $31,302 in Portland.

Jump to insightSolar scammers in Portland may falsely claim to be affiliated with a Multnomah County or Oregon government agency.
Jump to insightA typical solar panel installation costs anywhere from $9,275 to $26,500 in Oregon. Prices in Portland are comparable, ranging from $9,870 to $28,200.
This doesn’t include an energy storage battery, which sometimes costs as much as the panels: $7,000 to $18,000. A battery lets you store excess energy generated during the day and use it when your panels aren’t producing, like at night or during outages. It’s worth considering if your area gets frequent blackouts or if you don’t opt into Portland’s net metering program.
System size is the other major solar cost factor. The average Portland household needs a system with a capacity of 11.1 kW (kilowatt) to fully offset their electricity costs. Depending on how much energy you and your family use, you might need a smaller or larger one.
Average total solar installation costs by system size in Portland
5 kW | 6 kW | 7 kW | 8 kW | 9 kW | 10 kW | |
---|---|---|---|---|---|---|
Before federal tax credit | $14,100 | $16,920 | $19,740 | $22,560 | $25,380 | $28,200 |
After federal tax credit | $9,870 | $11,844 | $13,818 | $15,792 | $17,766 | $19,740 |
Getting solar panels is like buying a car. Most people pay cash, finance or lease. Similar to leasing, a power purchase agreement (PPA) lets you get the benefits of solar without actually owning the equipment.
» SOLAR PANELS: Lease vs. buy
Solar panels are generally worth it in Oregon if you like the idea of lowering your monthly utility bills. On average, Portland homeowners with solar panels can avoid $67,536 in total utility costs over 25 years.
The main drawback is the high upfront cost of purchasing and installing the panels and equipment. Assuming an upfront purchase, it takes about 12.5 years to break even (when your savings with solar panels make up for the cost).
Think of going solar in terms of your monthly costs. Given rising energy costs, financing solar panels makes sense as long as your monthly loan payment is less than what you would be paying the utility company anyway.
Considering Oregon averages 3 to 5 peak sun hours each day, switching to solar is worth considering. We suggest using NREL’s PVWatts Calculator to estimate how much electricity a solar panel can produce over a year on your house. Project Sunroof is a reliable online solar savings estimator.
Potential roof problems
As a rule of thumb, if your roof is more than 10 years old, consider fixing it before going solar. Installing solar panels on an old roof might mean you have to remove the panels, replace your roof and then reinstall the panels. This is an expensive and frustrating process.
» SHOULD YOU: Replace your roof before going solar?
In our experience, the best solar companies in Oregon have a few things in common: lots of experience, reliable equipment and transparent contracts. Here are some hiring tips.

Going solar in Multnomah County
We’re not aware of a totally free solar option in Portland. Companies may claim you can get solar panels for “free” or with little to no upfront cost. In reality, solar panels rarely come entirely free. These offers often involve hidden fees or long-term leases with escalating payments.
The 30% federal solar investment tax credit (ITC) is still the best incentive for most homeowners. It reduces your federal tax liability by 30% of how much it costs to install solar panels. Don’t get confused: The ITC is a credit, meaning it directly decreases the amount of taxes you owe. This is different from a deduction, which lowers your taxable income.
For example, if you spend $10,000 installing a solar panel system, the ITC is worth $3,000. If you owe $5,000 in taxes, the $3,000 credit reduces what you owe to $2,000. Any unused portion rolls over to the next tax year. However, getting a refund check is possible if the ITC credit reduces your taxes to the point where you overpaid during the year.
You can combine the ITC with local solar incentives in Oregon to maximize savings. For instance, you might be eligible for rebates through the Oregon Department of Energy or Portland General Electric incentives.
» BEST STATES FOR SOLAR: Oregon ranked 8th in 2024
Your homeowners association (HOA) can't stop you from installing solar panels, per state law. There’s also a solar property tax exemption, meaning your property tax bill won't go up because your solar panels increase your home’s market value.
» GREENEST STATES: Oregon ranked 4th in 2024
Yes, you or your installer can apply for a local solar permit through the city of Portland.
Net metering lets you send any excess power your solar panels generate into your local power grid. In return, you can earn credits on future utility bills. These credits can then offset your bill when your solar panels don't produce as much energy, like on cloudy days or during Portland’s long, dark winters.
Monocrystalline and polycrystalline are the most common types of solar panels used in residential installations. In general, monocrystalline panels are considered the best bang for your buck. Cheaper solar panels are typically polycrystalline. The key difference is in materials and efficiency: Monocrystalline panels use pure, single silicon crystals, while polycrystalline panels are made from melted silicon fragments, resulting in different efficiency levels.
Solar panel efficiency is a measure of how well a panel makes electricity. Standard efficiency rates range from 19% to 23%, which means 19% to 23% of the sunlight that hits the panels gets converted into electricity. The more efficient your solar panels are, the fewer panels you need. While more efficient panels cost a little more, you save by buying fewer panels.
A third party installs and maintains solar panels on your property. You buy the power generated by the panels on a per kilowatt-hour (kWh) basis. It’s typically a fixed price, with a cheaper cents/kWh rate than traditional utilities have for the same amount of electricity.
The ConsumerAffairs Research Team used a research-backed, data-driven approach, which was informed by our expert editors, to choose the best solar companies. We prefer to recommend those with a longer time in business and a solid track record of reliability in Portland, Oregon. For this guide, we objectively weighted several key features to get our final rankings:
Reviews, ratings and testimonials: 40%
We analyzed solar company reviews by verified solar customers to gauge real-world satisfaction. Companies with generally positive feedback on our site scored highest in this aspect. Those with the most 4 and 5-star reviews by verified Portland customers were given preference.
Warranties: 20%
A long warranty is important — it shows that a company stands behind its products and services. We compared companies on both equipment and craftsmanship warranty terms. All of our top picks for professional installation have warranties or production guarantees of at least 10 to 25 years.
Equipment selection: 20%
We evaluated each company’s selection of solar panels, storage batteries and inverters. Those with proprietary technology or a wide equipment selection from trusted brands ranked highest.
Financing and payment options: 20%
We gave preference to companies that offer multiple payment and financing options for transparent terms and conditions.
