Why Choose Cascadia Solar for Your Commercial Project
Every commercial solar project has unique requirements. That can include your building site, budget, energy goals, and aesthetic considerations.
At Cascadia Solar, we are authorized dealers for a broad range of solar equipment, giving us the flexibility to design a system around your needs, not specific products.
Here’s what that means for your project:
- Custom system design tailored to your building, energy usage, and long-term goals
- Product flexibility so you get the right equipment, not a pre-selected package
- In-house electricians handling installation with a focus on quality and safety
- Decades of experience from the team at Frederickson Electric
- Long-term support from a local company that will be here for the life of your system

Our goal is to deliver the best solution at the best value for your organization. We partner with you to design a custom solar PV (photovoltaic) system and install it using high-quality materials and experienced professionals.
With nearly fifty years of commercial electrical experience and deep roots in the Olympic and Kitsap Peninsulas, we’re a commercial solar contractor that will be here to service and support your system for decades.
Commercial Solar Batteries & Backup Power

For organizations that need reliable power during outages, solar can be paired with battery storage or a standby generator to support critical operations.
We design and install commercial battery systems using trusted equipment like Sol-Ark, Fortress Power, Tesla Powerwall, FranklinWH, and Enphase. These systems can help keep essential loads running when the grid goes down and give you more control over how your energy is used.
For larger backup needs or longer-duration outages, we also install commercial standby generators that can integrate with your electrical system.

Sustainability Goals
Demonstrate your commitment to clean energy and environmental responsibility in your community.
Clean Electricity Investment Tax Credit (48E)
Most commercial solar projects under 1MW qualify for a federal tax credit worth up to 30% of system costs. To be eligible, projects must begin construction by July 4, 2026 or be placed in service by December 31, 2027. Starting your project soon is key to securing this incentive!
MACRS Depreciation & Bonus Depreciation
Businesses can recover the cost of a solar energy system through accelerated depreciation. Most systems qualify for 5-year MACRS depreciation, and under current law, many projects are also eligible for 100% first-year bonus depreciation.
This allows businesses to deduct a significant portion, or potentially the full cost, of the system in the first year, improving cash flow and overall return on investment.
Net Metering
When your system produces more electricity than your building uses, excess power is sent to the grid and credited toward future usage.
Washington State Sales Tax Exemption
Commercial systems under 100 kW AC are exempt from sales tax in Washington, which can reduce the net cost of your project by close to 10%.
We’ll help you understand which incentives apply to your project and guide you through the process.
