Residential Solar

A solar system is your own personal power plant, silently delivering clean electricity into your home. Every kilowatt-hour (kWh) your residential solar system produces is energy you are not purchasing from your utility. Over time—as utility rates continue to increase—the rate at which you save continues to increase.

Why is now the best time?

Net metering

Export excess electricity to your utility as kWh credited to your account. Only pay for your net electricity usage.

PSE’s current net metering program is open to new projects through December 31, 2025.

Rising electric rates

Puget Sound Energy increased electric rates by 12% in 2025 and has been approved for an additional 6.3% increase in 2026.

Federal Tax Credit*

Homeowners are eligible for a Residential Clean Energy Credit on their solar system.

Under current policy, the credit is valued at 30% of the total system cost for systems installed through 2032. 

Sales tax exemption

Washington State has exempted solar installations from sales tax through 2029. This applies to the total installation cost, including equipment and labor.

So...how does residential solar work?

How we size your system

Our starting point is typically to design a system that covers 100% of the energy you use in your home. However, as the homeowner you have complete control over the scope of your solar system. We are happy to work with your goals and your budget to design the right solar system for you! 

1. Project Scope

Current Usage

We’ll tally up your current electricity needs to determine how many kWh you need to produce to eliminate your electric bill.

Future Usage

Planning on buying an electric vehicle or replacing an old gas furnace with a heat pump? We’ll account for that.

2. Site Specifics

Solar Resource

How much sun hits your roof depends on your location, roof pitch, surrounding trees, and more. We’ll calculate this!

Roof Conditions

Whether it’s a cozy craftsman or a simple shop, your roof’s size and layout will determine how large of a system we can fit.

3. Your Goals

Budget

Whether you pay out of pocket or finance with a loan, we’ll help size your system to match your budget and monthly goals.

Long-Term Plans

From boosting home value before a sale to lowering bills before retirement, we’ll design a system that aligns with your future.

Download your electric usage data

The first step to design your system involves sizing it appropriately for your electricity needs. These steps will walk you through downloading your historical electricity usage and a copy of your most recent bill, so we can get started on your system design.

FAQs

Utility customers who generate their own electricity and are connected to the utility’s distribution grid offset electricity that would otherwise be purchased from the utility. There may be times when the customer’s system generates more electricity than the home needs during the day, week or month. In these cases, a credit is issued to the customer’s account for the excess power, which can be used during the following month(s) until the annual true-up. In other words, the customer will only pay for the energy that the utility provides.

Per IRS.gov: “Traditional building components that primarily serve a roofing or structural function generally don’t qualify. For example, roof trusses and traditional shingles that support solar panels don’t qualify, but solar roofing tiles and solar shingles do because they generate clean energy.”

Due to weight limitations of the roof on a standard mobile home, roof installations are often not possible. Systems can be installed on manufactured homes if they were designed for a 30 lb/sqft snow load. Please refer to your manufactured home specifications, listed on the metal placard on the side of the home, to verify the snow load specifications.

Nope! The majority of our customers opt for a grid-tied solar system without batteries. They essentially use net metering to “store” excess electricity credit with their utility so they can use it later. Systems without batteries do not provide power during a power outage.
Solar installations which aren’t paired with batteries are required by the National Electric Code (NEC) to automatically shut down, so as not to back-feed the grid while utility workers are working to restore power. When an outage occurs, the system will turn off and no longer produce electricity. When grid power is restored, the system automatically turns back on and resumes active production.
