Solar panel costs in Tacoma

A typical solar panel installation costs anywhere from $9,117 to $26,050 in Washington. Prices in Tacoma are comparable, ranging from $9,212 to $26,321.

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 Tacoma’s net metering program.

System size is the other major solar cost factor. The average Tacoma household needs a system with a capacity of 7.1 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.
• 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 Tacoma?

Solar panels are generally worth it in Washington if you like the idea of lowering your monthly utility bills. On average, Tacoma homeowners with solar panels can avoid $31,108 in total utility costs over 25 years.

Switching to solar is also worth considering for the environmental benefits. The main drawback is the high upfront cost of purchasing and installing the panels and equipment. Assuming an upfront purchase, it takes about 14.16 years to break even (when your savings with solar panels make up for the cost).

The total cost of a residential solar photovoltaic (PV) system includes hardware costs (panels, inverters, racking, etc.) and soft costs (installation labor, permitting, marketing/sales, overhead).

While overall solar costs have dropped significantly over the past decade, soft costs have not fallen as quickly as hardware costs.

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 Tacoma

In our experience, the best solar companies in Washington have a few things in common: lots of experience, reliable equipment and transparent contracts. Watch out for door-to-door solar scams that attempt to gather your personal information, misleading claims, false advertising and aggressive sales tactics.

• Check certifications: In Washington, all electrical work (excluding work on your own property) must be done by a licensed electrical contractor using certified electricians. The state does not have specific solar licenses or certifications. We 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.
• Get quotes: Get multiple quotes from different solar companies to compare prices and services. Be cautious of companies that provide significantly lower estimates than others — this may indicate lower quality.
• 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.

Residential solar panel incentives in Tacoma

The 30% federal solar investment tax credit (ITC) is still the best incentive for a lot of homeowners. It reduces your federal tax liability by 30% of how much it costs to install solar panels. You can combine the ITC with local solar incentives in Washington to maximize savings. For instance, solar equipment is exempt from sales tax.

Federal solar tax credit expires at the end of 2025

The ITC is now set to expire at the end of the year, much earlier than previously scheduled. The credit was expected to drop gradually, then fully expire in 2035 — but those future step-downs have been eliminated under the “One Big Beautiful Bill,” signed in July of 2025. This means you have until Dec. 31, 2025, to install and pay for a system to qualify for the 30% credit.
