Central Wisconsin’s Worker‑Owned Solar Cooperative
Northwind Solar is a full‑service solar electric system provider based in central Wisconsin.
All of our work is done in‑house by NABCEP‑certified designers and installers and licensed electricians. That means you don’t have to worry about chasing subcontractors or surprise gaps in responsibility, we stay with your project from first conversation through long‑term service.
Since 2007, we’ve successfully installed megawatts of distributed solar across homes, farms, nonprofits, and commercial facilities throughout central Wisconsin.
We specialize in everything you need to make your solar PV installation successful, including:
- Utility interconnection and permitting
- Installation and system commissioning
- Ongoing service and support
- Site evaluation and solar resource assessment
- System design and financial analysis
- Incentive applications and grant writing
A Referral‑Driven, Worker‑Owned Company
In 2017, Northwind Solar transitioned into a worker‑owned cooperative. This business model strengthens our company by:
- Empowering employees to be co‑owners
- Using a democratic approach to major decisions
- Aligning the long‑term health of the business with the long‑term success of our customers
Today, our loyal staff of member‑owners means your system is designed, installed, and supported by the people who own the company, not a distant parent corporation. That ownership mindset is a big reason so many of our projects come from referrals and repeat customers.
