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.

Solar panel costs in Portland

A 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.

How can I pay for solar panels?

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 loans work like any other type of loan. They have relatively low fixed interest rates. Once you pay it off, you own your system outright. Check if you’re eligible for the Oregon Department of Energy's loan program.
• Solar leases are a good option if you have limited savings and don’t want to take on debt. A potential downside to leasing is that you won’t be eligible for the federal solar tax credit.

Is solar worth it in Portland?

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.

How to find a reputable solar company in Portland

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.

• Check certifications: Solar installers are required to have trade and electrical licenses, which you can verify through Oregon's license holder search Oregon's license holder search. We also recommend choosing an installer certified through the North American Board of Certified Energy Practitioners (NABCEP).
• Read reviews: Avoid companies with recurring complaints about misleading sales tactics, equipment failures, billing issues and lack of communication.
• Ask questions: Do you need a solar storage battery, electric vehicle (EV) charger or critter guards? How does this affect overall pricing? What if your system needs maintenance? If you don’t understand something about the payment terms, warranty or ongoing services, ask for clarification.

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.

Residential solar panel incentives in Portland

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.
