Thinking of going solar in Washington? 2025 is shaping up to be one of the best years yet for homeowners to make the switch — thanks to generous state and federal incentives that significantly lower your out-of-pocket cost.

At Sunergy Systems, we make it easy to take full advantage of every benefit available. Here’s your quick guide to maximizing solar savings in Washington State this year.

1. 30% Federal Solar Tax Credit (ITC)

The Investment Tax Credit (ITC) remains one of the most valuable incentives for going solar. In 2025, it allows you to:

  • Deduct 30% of the total cost of your solar system from your federal tax bill

  • Include batteries, installation, permitting, and equipment

  • Roll over unused portions if you don’t use the full amount in one year

đź’ˇ Example: If your system costs $20,000, you could save $6,000 on your taxes.

 2. Washington State Sales Tax Exemption

Unlike many states, Washington offers a full sales tax exemption for residential solar systems:

  • Applies to solar PV systems under 100 kW

  • Covers all materials and installation services

  • No application necessary — Sunergy Systems handles this automatically for you

This exemption typically saves homeowners an additional 8-10% off the total cost of going solar.

3. Net Metering Programs

Most Washington utilities offer full retail net metering, meaning:

  • Any extra energy your system produces is sent back to the grid

  • You earn bill credits at the same rate you pay

  • Credits roll over month-to-month, reducing your future electric bills

Sunergy Systems is familiar with net metering programs from utilities like Seattle City Light, Puget Sound Energy (PSE), SnoPUD, and more.

 4. Incentives for Battery Storage

While Washington doesn’t yet have a statewide rebate for batteries, the federal 30% tax credit also applies to solar battery systems like the Tesla Powerwall (when charged by solar).

Benefits of pairing batteries with your system:

  • Backup power during outages

  • Time-of-use bill optimization

  • Greater energy independence

We design all systems with battery readiness in mind so you can add storage now or later.

Potential Utility or City-Level Rebates

In 2025, several Washington utilities may continue to offer limited-time solar rebates or performance-based incentives (PBIs). Availability depends on location and funding, so it’s important to act quickly.

We monitor every available rebate opportunity and apply on your behalf when eligible.

With all these opportunities available, the best way to make the most of your solar investment is to work with a trusted local expert.

👉 Don’t Leave Money on the Table

Solar incentives in Washington are generous — but they won’t last forever. Some rebates are first-come, first-served, and tax credits are scheduled to decrease in future years.
