Decode the code: Residential solar panels

Sure, the PNW is cloudy most of the year, but the sun is still out there and it can help you save thousands on your electricity bill while keeping things green.

Let’s talk solar panels.

What’s solar power and how does it help?

Solar power harnesses the sun’s radiation to help reduce the cost of energy, contribute to a resilient electrical grid, and generate backup power.

Solar power has upfront costs for equipment — including photovoltaics or various types of panels — and installation but saves money over time, especially with the associated 22%-30% federal tax credit .

Local start-up cost is approximately $12,000-$16,000, but it pays itself off in six to eight years and saves ~$30,000-$50,000 over 25 years.

Local regulations

Once you get all your math done, your new solar panel installation will require a few permits to get set up depending on where you live.

Seattleites may not need building permits for their single-family residential installations as long as their project adheres to a series of conditions like the panels being mounted to lightweight rooftop material (like shingles) and that the structure meets fire code. Electrical and plumbing permits will still be required.

Getting started

In Washington, solar panels are typically installed on the south side of the roof for maximum sun exposure. Double-check with your neighborhood or homeowner’s association for specific guidelines when it comes to street-facing installations.

A qualified solar installer can help determine the appropriate size panel based on your energy consumption, roof size, and solar exposure.
