Wisconsin solar research farm mixes three panel layouts in one field to compare which design works best

Solar power generation is being paired with active farming across the United States.

These dual projects are key to raising green capacity while reconciling the two sectors.

In Wisconsin, university-led research is analyzing which agrivoltaic layouts will be more ideally suited to farming practices.

However, maintaining food production is also vital for national food security, especially as the sector is strained by climate change.

This will establish how livestock grazing, crop growth, and clean power generation can thrive together.

Which configurations will balance crop health, equipment movement, and energy efficiency all in one?

How flat, arable American land became highly contested

For generations, society has competed over land, but for several different reasons.

In the modern age, this competition has intensified between two sectors, namely the energy sector and agriculture.

In the United States, nationwide adoption of digital and electrical infrastructure has significantly increased electricity demand.

With AI data centers and cryptocurrency mining expanding, the EIA projects a 2026 power consumption of 4,288 billion kWh.

Meanwhile, this worsens the pressure on utilities that have to meet these demands while following strict decarbonization mandates.

To do so, solar power must significantly scale up.

This will potentially require up to 10 million acres of land for development by 2050.

Flat, sunny agricultural land has become the most cost-effective target for developers.

However, maintaining food production is also vital for national food security, especially as the sector is strained by climate change.

As a result, this has triggered immense conflict between solar development and agriculture.

Breaking rising trends of land-use competition

American Farmland Trust predicts that more than 80% of new large-scale solar could be developed on agricultural land. 

But this is only if current trends continue.

Since climatic shifts affect food production, and photovoltaics are meant to mitigate it, innovators decided to meet in the middle.

Dual-use agrivoltaic designs have been rising in popularity to avoid sacrificing food production for green energy.

Agrivoltaics is key to overcoming land-use conflicts by co-locating solar panels with active farming practices.

Furthermore, it helps the Department of Energy to promote solar capacity growth.

This approach also creates mutual benefits for both sectors.

The University of Wisconsin–Madison is testing the interactions between farming and solar production in real-world conditions.

The university partnered with Alliant Energy, and the field trials are being conducted at the Kegonsa Research Campus.

The research site itself is serving as a living laboratory to analyze different solar setups and their impacts.

Evaluating the best solar layout to boost benefits

Farming practices are increasingly beginning to share the same land with solar panels.

At the Kegonsa Research Campus, the goal is to understand the effect of different panel layouts on different agricultural methods.

The educational research mainly focuses on crop production, pollinator habitats, soil quality, and solar grazing.

The project itself generates enough green electricity to power up to 500 homes, helping the university to reach net-zero targets.

The three distinct configurations being tested

The setups are being tested side by side on one 16-acre field.

This is because farm machinery, different crops, and livestock require different levels of space, clearance, and light exposure.

There are 4,800 bi-facial panels with a standard fixed-tilt that evaluate impacts on shade patterns and crop growth.

The second layout entails 480 bi-facial single-axis tracking panels that pivot. This maximizes solar output while shifting shade patterns for ground vegetation.

Lastly, 144 bi-facial elevated fixed-tilt panels are raised 14 feet high to allow farm machinery to pass without obstruction.

The site itself is still new, and will be conducting long-term field trials over multiple years.

Initial observations demonstrate that the most beneficial layouts depend on specific farming needs.

For example, the most cost-effective bulk power generation is produced by standard fixed-tilt panels.

Ultimately, ongoing data collection will be essential in establishing the best solar configuration to create the ultimate balance.
