When the Windemuller family entered agriculture without a traditional farming background, they built Dream Winds Dairy from the ground up with a focus on innovation, efficiency, and long-term growth. As the operation expanded, they continued looking for ways to improve daily operations and incorporate new technologies to help the efficiency of the farm.
One of the biggest challenges they faced was the rising and unpredictable cost of electricity. With dairy operations relying heavily on power for equipment and daily farm functions, increasing utility costs made it difficult to forecast expenses and maintain predictable budgets. Looking for a solution that could provide long-term cost stability while supporting the farm’s continued growth, the Windemuller family turned to solar energy.
Dream Winds Dairy’s energy profile made it an ideal candidate for a custom solar solution, as most of the farm’s electricity usage occurs during daylight hours when solar production is at its peak. Key operations such as milking systems, refrigeration, and ventilation all draw significant power during the same time the sun is generating energy, creating a natural alignment for solar integration. After evaluating the site, the farm’s roof structure was also found to be well-suited for a flush-mounted system designed to meet the demands of a working dairy operation.
The final 100.8kW system was engineered with durability and reliability at the forefront, using high-quality materials built to withstand Midwest weather and support long-term performance. Just as important, the installation was completed without interrupting daily farm operations or impacting the animals below, demonstrating how solar can be seamlessly integrated into active agricultural environments. This solution was designed not only to meet current energy needs, but to support the farm’s continued growth and efficiency for years to come.
The impact of solar at Dream Winds Dairy became clear almost immediately after the system went live. As Paul Windemuller shared, monthly utility bills began to drop even as farm operations increased during peak seasons: “As the springtime came out, we got to see our power usage actually continue to drop month after month on our utility bill, which was really exciting. Every month, I pay less and less, even though we’re using more and more power during that time of year.” This shift reflects how the farm is now able to generate about 60% of its own energy during the exact hours it needs it most.
Beyond monthly savings, the system provides long-term cost stability that allows the Windemullers to plan for growth with greater confidence, free from the uncertainty of rising utility rates. Energy has shifted from an unpredictable expense into a controllable, strategic advantage that supports future expansion and equipment investments. At the same time, the solar installation reinforces the farm’s commitment to modern, sustainable agriculture, positioning Dream Winds Dairy as a forward-thinking operation in an increasingly environmentally conscious industry.
The financial impact of Dream Winds Dairy’s solar investment is both immediate and long-term, with an estimated $2,259,402 in utility savings projected over 30 years. What was once an unpredictable operating expense has now been converted into stable, measurable value, supported by a system designed for long-term performance and reliability.
Even more significant is the rapid payback period, estimated at less than 2.9 years, driven by utility savings, the 30% Federal Investment Tax Credit, and protection from rising energy costs. This means the farm begins seeing net positive returns quickly, freeing up capital that can be reinvested into herd expansion, equipment upgrades, and overall operational growth. These results are based on conservative projections grounded in real production data and actual utility rates, demonstrating how solar can deliver dependable, bankable returns for agricultural operations.
Lessons From The Field: What Other Agricultural Operations Can Learn
Dream Winds Dairy’s experience highlights how naturally solar energy aligns with Midwest agricultural operations. Many farms—especially dairy, grain, and poultry facilities—consume the most energy during daylight hours, which directly matches peak solar production. In addition, most modern agricultural buildings already have the roof space and structural capacity needed to support solar installations, allowing them to serve a dual purpose of housing operations below while generating power above.
The Windemuller family’s approach also shows that successful agricultural investment doesn’t require a traditional farming background—just a focus on efficiency and long-term financial performance. By turning one of their largest and most unpredictable expenses into a stable, predictable cost, they gained greater control over future growth and operational planning. Their experience illustrates a broader shift for Midwest agriculture: solar isn’t a departure from tradition, but an evolution toward greater self-sufficiency, resilience, and long-term stability.
