Transitioning Forward - A letter from Northwind founder, Josh Stolzenburg

Northwind Solar will Transition Forward


Note: This communication from Northwind Solar CEO Josh Stolzenburg is a

message to our stakeholders, clients, and friends about an exciting new

development at Northwind.


I’ve been consumed, for nearly two decades now, leading a passion project

called Northwind Solar. Originally conceived to provide meaningful work for

those who wanted to advance climate and energy solutions, we’ve grown into

one of Wisconsin’s most effective and respected solar companies. Thirty

committed employees (of whom 16 share ownership) now work out of our

Amherst office.


The time has come for me to step out of the role of CEO, shift my Northwind

work to new priorities, and cultivate next generation leadership.

As a company, we have matured over the years and come a long way from the

conceptual white boards I scrawled on the walls of a friend’s basement in 2007,

My crude “business plan” evolved from educational work (with the Midwest

Renewable Energy Association) which fueled my desire to put meaningful green

kilowatt hours on the Wisconsin grid to offset fossil fuel use. I engaged a couple

of technically proficient business partners in 2008 and we began to offer wind,

solar heating, and solar electric to suit the needs of a growing customer base. In

the mid-teens we shifted our exclusive focus to solar electric (including battery

systems and, now, smart electrification).


From the beginning, community involvement was an important corollary to our

professional work. My early involvement with the development of the Central

Rivers Farmshed and work with the WI Farmer’s Union led to compelling work

with and support for local small farms. Until recently, I’ve advised Mid-State

Technical College’s renewable energy program since it’s inception in 2008 and

we’ve been able to hire graduates of that program consistently since 2010. I’ve

served on the Renew WI board of directors since 2019 and helped to create

SolarShare WI, a thriving community solar investment cooperative.

Part of the Northwind ethos has been distributed management and shared

ownership. We formalized that in 2017 when we converted from a partnership to

a worker owned cooperative. Employees could buy in, become owners, and

share in the financial rewards and governance. In the seven years since there

have been challenges, successes, and changes in personnel as we have learned

to be a democratic company.

The face of the company has changed over time. We’ve been blessed with some incredible contributors who are no longer with us. One of those, former board chair Rob Peck, recently said when asked about the transition:


 “Every pirate ship needs a captain. In the early days, I had no idea how much vision and passion was in Josh’s entrepreneurial head. Now, the table is set. So many key people in place. The foundational ethos of Northwind has been institutionalized. The lodestar is clearly in sight to guide the course of this ship.”


But the amazing people who are here are confidently building Northwind into a stronger company and strengthening our community ties. The values that the company was founded on carry on. I am deeply proud to be a part of this - and I can’t wait to see where we go from here. 


Courtney Berner is the Executive Director of the UW Center for Cooperatives.

She has helped us in countless ways during our journey. Courtney says,

"As Josh steps out of the role of CEO, he is leaving a powerful legacy. He built a top

notch business that is accelerating the renewables transition and then, by selling

it to its employees he ensured its future as a central Wisconsin community

anchor. Growth and change always come with challenges, but Northwind is well

poised for its next chapter."


So that tells about the current state of Northwind and how we have come to be

who we are. But what about me as I transition out of the CEO role, and my

replacement?


The state of the solar industry in WI has improved dramatically, but there’s a lot

of organizing and policy work to do to protect consumer interests and ensure

robust market conditions for the growth and future success of distributed solar for

Wisconsin. That work is my current passion and will be the focus of my

Northwind work going forward.


Meanwhile, we are currently engaged in an exhaustive effort to identify, onboard,

and guide the best person to carry forward in the role of operational leader of

Northwind.

Northwind Founder

I hope you'll follow and support our journey

and help us to a build a brighter, more

resilient future in central WI and beyond.

Right now, the federal Investment Tax Credit (ITC) offers a 30% tax credit to businesses that install solar energy systems. Originally scheduled to continue through 2033, the current Senate version of the bill maintains this 30% rate only through the end of 2025. After that, the credit is set to step down sharply: 18% in 2026, 6% in 2027, and 0% in 2028 and beyond. Don’t Miss the Safe Harbor Window Fortunately, there’s a way to lock in the full 30% credit before it’s reduced. Under the IRS’s "safe harbor" provision, you can preserve the full ITC by beginning physical work on your project or making a minimum 5% down payment by the end of 2025 — even if your system is completed in 2026. This is a powerful opportunity to secure long-term financial benefits while the full federal incentive is still available. Stackable Incentives Make the Financials Even Better Beyond the ITC, there are several additional programs that can dramatically reduce your project’s net cost: 10% Domestic Content Bonus: Earn an extra 10% tax credit for using U.S.-made solar components. Focus on Energy Rebates: A Wisconsin-based program offering upfront cash rebates for solar projects. MACRS Accelerated Depreciation: A federal tax benefit that allows you to recover the cost of your solar system more quickly through tax deductions. Solar Central Wisconsin Grow Solar Group Buy: Group pricing and additional resources that make going solar more affordable for local businesses. When stacked together, these incentives can cover a significant portion of your total investment, all while reducing your energy bills for decades to come. Why Act Now Solar has always been a smart investment, but today’s environment is uniquely favorable. With utility energy costs rising and key federal credits sunsetting, 2025 is the year to take action. Whether you’ve previously explored solar or are just getting started, revisiting your project now could mean locking in tens of thousands of dollars in savings. Northwind Solar can help you navigate every step, from incentive qualification to project design and installation. Improve your profitability by making a high-performing energy investment in your business. Achieve energy independence, support local businesses, and contact Northwind Solar today!

Northwind Solar is proud to continue its partnership as the official installer for the 2025 Grow Solar Central Wisconsin Group Buy Program , in collaboration with the Midwest Renewable Energy Association ( MREA ). This initiative offers homeowners and small businesses in Portage, Marathon, Waushara, Waupaca, Wood, and Lincoln Counties an exceptional opportunity to invest in solar energy at below-market rates through a limited-time group purchasing program. However, a critical deadline is approaching. Recent legislative developments indicate that the 30% federal Residential Solar Tax Credit —a significant incentive that substantially reduces the cost of solar installations—may expire on December 31, 2025, nearly a decade earlier than previously scheduled. This potential change underscores the urgency for homeowners to act swiftly to secure both the group buy discounts and the federal tax credit. “We’re excited to once again be working with the Grow Solar program to expand solar access in our region,” said Woody Bolton, employee-owner at Northwind Solar. “With the possibility of the federal tax credit ending soon, it's more important than ever for our neighbors to take advantage of these combined savings.” The Grow Solar program facilitates community members joining forces to leverage bulk pricing for solar installations, significantly reducing the cost of going solar. The program features free educational events, called Solar Power Hours, which help residents learn about solar energy, how it works, available incentives, and what to expect from an installation. “In times of uncertainty and climbing prices, one thing remains the same: we all need electricity,” said Evonne Waugh, program manager at MREA. “Investing in solar means securing lower bills for many years ahead.” Since its inception, Grow Solar Central Wisconsin has helped over 250 households and businesses make the switch to solar, adding nearly 2 megawatts of clean energy capacity to the local grid and generating millions of kilowatt-hours of renewable power annually.
