As Alberta’s photo voltaic trade has grown, so too have issues concerning the impact the panels have on soil well being.

It’s a problem the Rural Municipalities of Alberta, amongst others, have raised. The RMA says approvals for renewable tasks similar to photo voltaic developments — the province has a maintain on approvals till March — “ought to think about the productiveness and local weather change adaptation prices of taking food-producing land out of service.”

However there are methods to take care of and even enhance soil well being on photo voltaic farms, say many gamers inside the photo voltaic trade.

Jason Bradley, president of Regener8ve Ag, Inc., is selling a nature-based strategy with vitality corporations and agricultural producers referred to as regenerative agrivoltaics, which goals to enhance soil well being and the nutrient density of crops planted by photo voltaic panels whereas growing earnings for farmers and ranchers.

“It’s usually cutting down the tools or sort of apparatus getting used in addition to rethinking livestock reintegration on the similar time inside these giant arrays,” stated Bradley, including that utilizing cowl crops and crop mixtures are amongst different methods.

“All of it’s centered on the primary precedence, which is to extend purposeful soil well being,” stated Bradley, a resident of Olds, 80 kilometres north of Calgary and a former supervisor of a big ranching operation.

The strategy ensures collaboration between the landowners and photo voltaic corporations, with each benefitting from it.

Photo voltaic arrays might be positioned on farmland of assorted high quality, he stated.

“It’s not about placing photo voltaic on marginal land,” Bradley stated. “The strategy of regenerative agrivoltaics is to make use of that present excessive manufacturing (farm) land, and when these photo voltaic farms are being designed, constructed and put in on these places, is to then produce the identical quantity of meals energy per acre as was present earlier than photo voltaic was put up.”

Ryan Tourigny, co-founder and director of Vitality Harvest, a photo voltaic firm that focuses on including photo voltaic to land that may be continued for use for farming, stated he was skeptical at first that farming might be carried out inside photo voltaic fields.

“The concept we may make as a lot meals in a photo voltaic farm and get clear electrical energy actually blew our minds,” he stated, including it’s “completely potential.”

Photo voltaic panels are a method of mimicking the pure surroundings, like the way in which a row of bushes shelters a crop from wind, stated Tourigny.

“That modified our mind-set, that it’s not one thing impeding farming however to actually embrace that biomimicry of the form and structure of the photo voltaic facility,” he stated.

For producers, the lease income makes it much less dangerous to have photo voltaic panels on their property, stated Tourigny.

“As a result of there’s fixed income coming in for the producer from the photo voltaic facility over time, they will experiment, they will attempt issues that may in any other case be too dangerous to implement,” he stated, including producers are then desirous to share their findings with their neighbours.

Tourigny stated the photo voltaic trade must work nearer with agriculture producers to seek out methods to assist them financially and enhance soil well being.

“The trade has a methods to go, however I’m assured we’re going to rise to the problem with the assistance of farm communities,” he stated.

The trade, together with Vitality Harvest, is seeking to a challenge at the moment below building, the four-megawatt SunRISE Photo voltaic in Cardston, to display agrivoltaic approaches for future use in large-scale photo voltaic amenities. The challenge, owned by Clear Communities Corp, of which Tourigny is president, is seen as an important step to eradicating limitations, together with insurance coverage and financing issues, from giant agrivoltaic tasks.

On ranches, one problem is getting cattle to graze close to photo voltaic farms, as they’re giant, “like to scratch and have habits of their very own,” stated Tourigny.

“We’re getting there, we’re discovering methods of doing it, and there’s undoubtedly extra demand available in the market to have extra cattle grazing,” he stated.

A Calgary-based firm is addressing the challenges round having cattle graze by photo voltaic panels. Jon Bichel, chief working officer for Solartility Inc., stated the corporate is working with a producer on a vertical racking system that retains the photo voltaic panels shielded from cattle and minimizes the quantity of land the panels occupy.

“Then the cattle can nonetheless eat the grass beneath,” stated Bichel. “Primarily, there needs to be no change to the output of the vary, however you get the extra incentive of the revenue sharing from the photo voltaic income. It will increase the greenback per acre income of the land considerably.”

Bidel stated Solartility is at the moment centered on photo voltaic tasks below one megawatt as a result of province’s moratorium, which has positioned a pause on wind and solar energy approvals tasks higher than one megawatt. The corporate is engaged on 25 such tasks, primarily between Calgary and Edmonton, and hopes to finish 10 subsequent yr, he stated.
