Agrivoltaics, the fusion of agriculture and solar power generation, has created a new approach, and viable option, to how we approach sustainable farming and energy production.

As the world shifts towards renewable energy sources, a new player emerges in the US: vertical agrivoltaics. At first glance, it looks like someone just upended a solar panel vertically and while that’s true (and, technically, correct) it’s the method to the madness that could well make a sizeable difference in agriculture.

Vertical agrivoltaics may help redefine sustainable farming and renewable energy at just the time as the world continues to grapple with food scarcity, climate change chaos, and carbon emissions, not to mention the vast amount of greenwashing and its many newly minted cousins that companies have greedily adopted.

What is Vertical Agrivoltaics?

Vertical agrivoltaics is a smart twist in the solar energy playbook, blending agriculture with solar power in a way that respects land use. This approach turns the tables on typical solar farms that hog up vast fields. Instead, it stands out by slotting solar panels vertically, making them more like tall fences in the fields rather than sprawling sun catchers.

In the US, solar developer iSun and German company Next2Sun are spearheading the first vertical agrivoltaics system. Their game plan is unique: they’re using bifacial solar panels mounted vertically. The cool part? These panels work their magic during off-peak hours and avoid monopolizing agricultural land. This method isn’t just theory; it’s already a hit on farms in Germany.

Slated to start construction in 2024 in Vermont, this pioneering system will stretch over 3.7 acres. It’s not just a couple of panels here and there – we’re talking about 69 vertical rack elements, each cradling two bifacial solar modules. And here’s the cherry on top: the space between these solar rows will be home to root veggies like carrots and beetroot, and even some saffron.

Jeffrey Peck, the big boss at iSun, sums it up nicely: “Thanks to the vertical mounting of the modules and the adaptability of the installation to the needs of the farmer, the valuable land is almost completely preserved for agriculture.”

So, how does this all stack up against the typical solar power setups? Let’s dive in and find out.

Top 3 Advantages of Vertical Agrivoltaics

Now, let’s chat about the cool perks of going vertical with solar panels. It’s not just about sticking panels up in a new direction; it’s about getting smart with our space.

Friends with Farms

First off, vertical agrivoltaics is like a best buddy to farmers. It lets them keep most of their land for crops while sneaking in some solar power generation. Imagine solar panels standing tall like guards, letting veggies grow undisturbed underneath. It’s a win-win for farming and energy production.

Sun Chasers

These panels aren’t picky about where they face. Traditional panels need that perfect south-facing spot to soak up the sun. But vertical panels? They’re cool with an east-west setup, thanks to their bifacial design. This means they can catch sunlight coming and going, making them surprisingly efficient.

Everywhere Energy

And here’s the kicker – these panels aren’t just for fields. They can line up along highways, railways, and even on balconies in urban jungles. It’s like turning every spare inch of space into a mini power plant.

In California, there’s already a glimpse of this future. Sunzuan’s vertical system, rocking 43 panels at a winery, is cranking out 23 kilowatts of power. That’s not just a few light bulbs; it’s serious energy.

But hey, no solution is perfect, right? There are some challenges and limitations to consider too.

3 Main Challenges and Limitations

Alright, let’s keep it real for a minute. Vertical agrivoltaics sounds pretty slick, but it’s not all sunshine and high yields. There are a few bumps in the road we need to consider.

    1. Cost Conundrum: First up, money matters. While vertical panels are easier to install than the traditional elevated ones, they’re still not cheap. Setting up a new technology always has its price tag, and this is no exception. We’re talking about a balance between upfront costs and long-term gains.
    2. Patience is Key: Then there’s the waiting game. Unlike traditional solar panels that have been around the block, vertical agrivoltaics is relatively new on the scene. This means there’s a bit of trial and error involved. Farmers and investors need to buckle up for a journey that might have a few twists and turns.
    3. Playing the Long Game: And here’s the big one – results take time. Just like planting a seed and waiting for it to grow, vertical agrivoltaics needs time to show its true potential in terms of energy output and agricultural benefits. It’s not an overnight success story.

Despite these challenges, it’s clear that vertical agrivoltaics has a lot to offer, especially when we weigh the economic and environmental impacts. So, let’s dig into that next.

Talking Dollars & Sense

Now, let’s talk dollars and sense – and by sense, I mean the environmental kind. Vertical agrivoltaics isn’t just a cool concept; it’s got some real clout when it comes to saving bucks and the planet.

    1. The Cost Comparison: Sure, the initial setup for vertical panels might make your wallet a bit lighter, but think about the long haul. Compared to traditional solar farms that need a ton of space (and money), vertical setups are like the savvy savers of solar energy. They use less land and can be squeezed into existing spaces. Plus, their dual-purpose nature means you’re getting more bang for your buck.
    2. Earth-Friendly Energy: Environmentally, it’s a breath of fresh air – literally. By pairing up with agriculture, these vertical panels are doing double duty: generating clean energy and supporting sustainable farming. Less land for solar farms means more green space, and we’re all about keeping it green.
    3. A Sustainable Shift: This isn’t just about today or tomorrow. Vertical agrivoltaics is playing the long game in sustainability. By smartly integrating solar power into our landscapes, we’re paving the way for a more energy-efficient future that doesn’t step on Mother Nature’s toes.

In the grand scheme of things, the investment in vertical agrivoltaics seems like a smart move, not just for the wallet but also for our planet. Up next, let’s take a peek at some real-world examples and see this tech in action.
