The Solterra sales team got together in West Seattle this week to talk through some exciting projects ahead (more on those soon 👀).

While we were together, one thing kept coming up: solar is changing fast in Washington. If you’ve been thinking about making the switch, now’s a smart time to explore your options while incentives like 1:1 net metering are still available.

And when you work with a local Seattle team, you get people who understand Washington weather, local permitting, state incentives, Seattle-area utilities, and how to design a system that actually makes sense for homes here.

☀️ Is a solar battery worth it in Washington? 🔋

⛈️ If you want to stay powered when the grid goes down, reduce your reliance on your utility company, and maximize the value of your solar investment — yes, a backup battery is worth it. 💡🔌

🤔 But the real answer depends on your home, energy goals, and what you're willing to pay for peace of mind.

For , let's uncover: how clean is solar energy in Washington?

Solar energy is both renewable (source is naturally replenished) and clean (the total environmental impact is low). Here's how solar stacks up in the context of Western Washington's energy grid:

💡 Operational emissions: Solar produces zero emissions while actively generating electricity, providing clean energy from your rooftop for decades.

🏭 Lifecycle emissions: Solar does produce carbon emissions during manufacturing, but typically pays back its carbon debt within 1-4 years of installation.

♻️ Solar panel recycling: Solar panels are 90% recyclable. When homeowners are ready to upgrade their system, Solterra Solar will buy back their panels and recycle them, keeping them out of landfills and reducing the need for mining.

🌊 Solar vs. Hydropower: Washington's grid is 60% hydropower, making it one of the cleanest in the nation. However, hydro doesn’t offer homeowners energy savings, harms local river ecosystems, and is vulnerable to drought. We need both to transition confidently to a 100% clean energy future.

Take a full look at solar power's environmental impact, solar panel recycling, and how solar stacks against grid alternatives like hydropower in Western Washington in our Earth Day blog post: https://solar.solterra.com/is-solar-really-clean-energy/.
