At sites around the country, fields, farms and green forests are reduced to gravel lots to make way for utility-scale solar plants. In some cases, carefully cut Kentucky Bluegrass is allowed to grow under the panels.
Just off Hover Road south of Longmont, a solar project is breaking that mold. Salt grasses, berry bushes, vegetables and hay flourish between the rows of elevated photovoltaic panels. Jack’s Solar Garden is the largest active commercial research facility in the United States for “agrivoltaics,” a land-use model that combines agriculture with solar energy. In just a few hectares, the site grows produce for a local farm, produces enough electricity to power 300 homes and hosts researchers from three separate institutions. The project preserves the tradition of the land, which is a third-generation hay operation. At the same time, it is well positioned for a future in which Colorado’s energy needs are increasingly met by renewable sources.
The idea behind agrivoltaics is simple: use the “empty” space under the solar panels to grow things. However, the concept is still young. Agrivoltaic and research sites are owned and operated by a few lawyers in the country. During this legislative session, two Colorado senators plan to introduce a bill that could position the state as a leader in agrovoltaic research.
This is not the first time that the topic has been brought to the state. In 2021, Senate Democrats passed Senate Bill 235, which provides $3 million in funding for Colorado’s Advanced Renewable Energy and Energy Efficiency program. Of this, a small part was allocated to the purchase of equipment for agrovoltaic operations.
“We are not the first state to recognize agrivoltaics, but we are the first state to establish agrivoltaics in statute, as well as funding from state funds,” said Senator Sonya Jaquez Lewis, the first sponsor of the project.
Jaquez Lewis credits Jack’s Solar Garden for his interest in agrivoltaics. After visiting the facility, located in her district and only 10 minutes away from her home, she was hooked.
A year later, the agrivoltaics appeared in the Capitol once again. Senate Bill 22-138, sponsored by Denver Democrat Chris Hansen, did not go as far as its predecessor. Five years of funding for agrovoltaic research has been proposed with a mix of policies aimed at reducing greenhouse gas emissions in Colorado. House Republicans mounted a last-second filibuster, killing the legislation.

So far, every funding bill for agrivoltaics has been supported primarily by Democrats. In 2023, a Republican lawmaker from Alamosa intends to change that. Senator Cleave Simpson first became interested in agrivoltaics as a potential solution to the problems his family faced on their 800-acre alfalfa farm. Years of water scarcity have made the operation financially tenuous.
“I’m trying to figure out how to make my farm self-sufficient in many respects — energy, soil health and water,” Simpson said. “All these things come together in this conversation around agrivoltaic.”
Simpson predicts that his constituents share his interest in the new technology. Over the past two decades, he has seen nearby farms and ranches struggle to stay afloat.
“If the next 20 years are anything like the last 20 years from a water supply perspective, there’s probably 100,000 acres in the valley that doesn’t have an adequate water supply,” he said. “The whole community’s economy, culture and community are built around irrigated agriculture and I just see this freight train going down the track. I’m regularly looking for solutions.”
At its heart, agrivoltaics is a marriage of traditional land use with future infrastructure. Instead of uprooting crops to make way for energy production, landowners could adapt the agricultural operations of the time to incorporate a second source of income.
“The economy is certainly the biggest driving factor,” Simpson said. “I don’t want to risk the economic viability of my family farm and the future of my son and the future of my grandson.”
On Tuesday, Democratic Governor Jared Polis reiterated his goal for Colorado to generate 100% of its electricity through renewables by 2040 in his fifth year of the State of the State. The goal is part of a broader effort to reduce greenhouse gas emissions in Colorado. Last year, major utilities, including Xcel Energy, submitted clean energy plans to the state detailing how they would contribute to the transition.
Microclimates
For a farmer, the potential value of an agrovoltaic project is twofold. First, there is the solar energy itself, which the farm can use to power its operations or generate revenue through a lease agreement from a solar developer.

As the sun moves across the sky, the panels of Jack’s Solar Garden trace their course along a single axis. Below them, a shadow moves across the ground and rainwater is deposited along the descending edge of each panel. Before the farm became a sun garden, each square foot received roughly the same amount of sun and moisture. Now, the field is divided into a series of “microclimates”.
This concept is central to the alleged benefits of agrivoltaics. Different conditions on the same land increase the opportunity to grow different crops. In grasslands, agrivoltaic installations could promote more diverse plants, insect pollinators and soil microbiota – essential elements for long-term sustainability.
“For the landowners here, if you can increase productivity across the board – great. If you can keep productivity the same – great, because you’re also creating energy,” said Colorado State University doctoral student and agrovoltaic researcher Matt Sturchio . “If you can slightly reduce productivity, but increase biodiversity and also resistance to climate extremes like drought and heat waves – win-win again, right?”

The idea that solar panels could help crops survive drought is an alluring concept in the arid farmlands throughout Colorado and the desert Southwest. Water is still in short supply, and evidence is growing that agrovoltaic operations could help. A 2019 study led by University of Arizona researcher Greg Barron-Gafford found that jalapeños and tomatoes used irrigation water more efficiently under the protective shade of photovoltaic panels at an outdoor field site. of Tucson. At Jack’s solar garden, partner organization Sprout City Farms grows vegetables, herbs and berries under shade panels.
Researchers like Sturchio hope that similar benefits could play out in native grasslands, hay fields and pastures. In addition to shade plants, the panels could provide shelter for animals from the midday sun.
Soon, a private sector project will put the theory to the test. In August, Delta County commissioners approved the Garnet Mesa Solar Project, which will pair 80 megawatts of solar capacity with 1,000 local sheep. When finished, it will be more than 60 times larger than Jack’s Solar Garden, reclaiming the title of the state’s largest agrivolatic facility.
Scaling up
Alexis Pascaris, the founding director of AgriSolar Consulting, has spent countless hours interviewing farmers about their views on agrivoltaics. Read also : New England Solar Power: A Guide to Solar Energy in These 6 States. They generally fall into two camps.
“It’s either ‘stay off my farmland’ or ‘it’s amazing, how can I take advantage of those benefits to support my farm and my production?'” he said. Farmers who are interested want to know one thing. “They value the “social and environmental attributes, but, at the end of the day, we have to write financially”.
This logic was at the heart of the impetus for Jack’s Solar Garden. In 2016, Byron Kominek moved to the family farm after five years as an American diplomat in southern Africa. At that time, the farm was producing hay. But the margins on the crop were slim compared to when Kominek’s grandfather, Jack, ran the operation in the 1970s and ’80s.
“Haying was interesting, but he didn’t do anything for money,” Kominek said. “And every year we were getting less and less water to irrigate that really thirsty bromegrass.”
When Kominek went to the Boulder County Department of Land Use to ask if he could build a solar array on the property, they shot him down. He could run a Christmas tree farm or an equestrian center, but they wouldn’t allow him solar panels. No matter what grows under the panels, the project was seen as a power plant.
Kominek is an unusually persistent person. Over the course of three years, he convinced county officials to let Jack’s Solar Garden be built and sell shares of the operation to local landowners. Now, the income from the electricity produced in the farm is slowly draining the bank loan that financed the construction, and Kominek has become a prominent advocate in the problem.
For many, Jack’s Solar Garden is a model for what is possible with agrivoltaics. Kominek hopes it’s a catalyst for something bigger. “Are we going to continue with projects the size of mine, or are we going to start installing systems of 10 megawatts, 50 megawatts, 100 plus megawatts that are intended for agrivoltaics?” he said.
Other agrovoltaic advocates agree. For Sturchio, a large-scale project combined with state funding could take his research to an unprecedented scale.
“How many sites are built for agrivoltaics, and how many have kept the land intact? Not many,” he said. “More money is important to build bigger designs.”
They value social and environmental attributes, but, at the end of the day, it’s got to pencil financially.

Simpson hopes that large-scale agrovoltaic projects could provide an example for farmers like his constituents in the San Luis Valley. “I visited Jack’s Solar Garden last summer and spent time with Byron. It’s quite impressive to see what he has accomplished, from my perspective, on a small scale,” he said. “I need to be able to do it on 120 or 160 acres at a time and, you know, do it 50 times, or 100 times.”
Two things stand in the way of grand visions for large-scale agrovoltaic projects. The first is physical. Large-scale renewable energy projects require high-capacity transmission lines. Xcel’s Power Pathway project will bring this type of infrastructure to much of eastern Colorado in the coming years, but places like the San Luis Valley are lagging behind.

“All the supply for the San Luis Valley comes from two lines that generate the north of the valley and come over Poncha Pass,” Simpson said.
Valley legislators have long discussed a second line in the valley from the east, but there is no concrete plan to expand the transmission infrastructure. For now, new renewable projects are limited by capacity.
The second obstacle is financial. Colorado’s general fund will be stretched next year, as the Taxpayers’ Bill of Rights (TABOR) limit on state revenues lags behind inflation. Even if Simpson and Hansen’s bill passes, it may not be funded for another year.
“It’s really challenging this year to try to appropriate every dollar for it,” Simpson said. “We can at least get statutory authority.”
Meanwhile, six Department of Energy-funded projects in other states will test the viability of utility-scale agrivoltaics in different climates and land use categories. As of now, Jack’s Solar Garden has established Colorado as a leader in the field. If the state wants to maintain that status, it will need to scale.
Pourquoi un onduleur hybride ?
The hybrid inverter Depending on the settings, it is able to determine by itself whether the electricity produced must be used immediately, stored in a battery, or injected into the network. The enclosure can be connected to the generator set to provide backup power in the event of a power outage.
How to choose a hybrid inverter? Your inverter must reach a power of about 80% of your solar installation. For example, your installation is 6 kWc, the inverter must have an ambient power of 4.8 kVA. You can therefore opt for a 5kVA inverter.
How to pair two inverters? It’s very simple because the connectors prevent you from going wrong. For the station at the beginning of the chain, you start from the connector on the right of the microinverter and connect it to the connector on the left of the microinverter on the second panel, and so on.
