Two developments have emerged in recent times to help the US photo voltaic power trade. One is agrivoltaics and the opposite is neighborhood photo voltaic. For essentially the most half they’ve been working on separate tracks, however a raft of latest tasks in Massachusetts signifies that agrivoltaics and neighborhood photo voltaic are merging into a robust new super-trend that may shut the door on fossil-fueled energy vegetation as soon as and for all.
Agrivoltaics And Neighborhood Photo voltaic
Agrivoltaics represents a sea change within the growth technique for utility-scale rural photo voltaic tasks. Within the early 2000’s, photo voltaic builders most popular gravel or different low-maintenance floor cowl. Photo voltaic panels had been nonetheless comparatively costly again then. To chop prices, builders saved racking techniques as quick as attainable and spent the naked minimal on floor preparation.
Now that the price of photo voltaic panels has plunged, photo voltaic builders have some room to spend money on different methods whereas nonetheless providing ratepayers the chance to cut back their utility payments. That has opened the door to agrivoltaics, wherein builders spend money on specialised racking techniques and new photo voltaic applied sciences which can be designed to allow farming actions throughout the photo voltaic array.
Livestock grazing and pollinator habitats have dominated the agrivoltaic subject so far. Researchers are additionally compiling a information base that allows agrivoltaic arrays to develop into meals crops for people (see extra solar-plus-farming background right here).
In the meantime, the neighborhood photo voltaic motion has additionally been taking a ride-along with the falling value of photo voltaic power.
Neighborhood photo voltaic tasks present a manner for everybody to help solar energy of their space. If ratepayers don’t have the chance or need to put in their very own photo voltaic panels, they’ll subscribe to a close-by neighborhood photo voltaic array. In previous years additionally they needed to pay a premium for photo voltaic entry, however now the standard neighborhood photo voltaic subscriber is more likely to see their utility payments fall.
New Agrivoltaic Tasks For Massachusetts, With A Neighborhood Photo voltaic Twist
Massachusetts was amongst one of many first states to come back throughout the CleanTechnica agrivoltaics radar again in 2019, when agricultural planners within the state went scouting for methods to maintain the state’s cranberry trade.
By 2021 the cranberry farming angle was starting to draw curiosity with an help from the Massachusetts SMART photo voltaic incentive program, although a hitch associated to the form of poles used to raise the photo voltaic panels slowed issues down. Within the meantime, the agrivoltaic motion has exploded all throughout the US with tons of of dual-use photo voltaic tasks at the moment beneath manner.
In Massachusetts, the SMART program continues to help new agrivoltaic tasks. The newest growth is a set of 5 new agrivoltaic tasks with a neighborhood photo voltaic aspect, beneath the umbrella of the photo voltaic developer and authorized B Corp BlueWave. All collectively, the tasks could have a capability of virtually 20 megawatts alongside a storage capability of virtually 30 megawatt-hours.
“Each of the solar projects are uniquely designed to allow for uninterrupted farming operations beneath the solar arrays with sites featuring a varied selection of crops and pollinator-friendly livestock grazing operations,” BlueWave defined in a press launch on August 22.
The neighborhood photo voltaic aspect is exemplified by Lowell Normal Hospital, which stepped as much as function an anchor companion for 2 tasks, in Palmer and Haverhill. The association commits the hospital to obtain half of the power power capability from the 2 tasks, leading to decrease utility payments. BlueWave additionally notes that the tasks present low-income residents with entry to low-cost clear power, with out having to pay up entrance for photo voltaic panels.
“As the solar farm generates electricity, utilities measure the amount produced and assign that energy a dollar value in the form of a solar credit, which is applied to subscribers’ monthly electricity bills, reducing what residents owe,” BlueWave explains.
Saving Cash, Serving to Farmers
The SunSmart Ames Neighborhood Photo voltaic Venture close to the Ames Municipal Airport in Ames, Iowa, is one other good instance of the interaction between agrivoltaics and neighborhood photo voltaic tasks. Commissioned in 2020, the 10-acre photo voltaic array was initially developed just for electrical energy manufacturing. Earlier this 12 months the Ames Tribune famous that the challenge has recruited an area sheep farmer to graze his sheep on the web site. The associated fee-cutting measure eliminates carbon emissions from mowing gear whereas supporting an area agricultural enterprise.
Citing sheep proprietor Chad Steenhoek in a Metropolis of Ames press launch, the Tribune additionally teased out how strategic grazing will help restore depleted soil.
“With targeted grazing by sheep, we’re able to eat the vegetation in a manner that stores more carbon in the ground,” Steenhoek explains. “By storing more carbon, we improve soil life in the soil. As the soil improves, that creates a better environment for grass. It’s a good cycle.”
How The Agrivoltaic Motion Can Transfer The Rural Photo voltaic Needle
Don’t simply take his phrase for it. Of their August 22 press launch, BlueWave notes that it really works with the farmland conservation efforts of the group American Farmland Belief, which credit itself with launching the conservation agriculture motion. “Since our founding in 1980, AFT has helped permanently protect over 8 million acres of agricultural lands, advanced environmentally-sound farming practices on millions of additional acres and supported thousands of farm families,” the group explains.
Assist from AFT comes at an important time for US the photo voltaic trade, which is going through opposition to utility-scale photo voltaic tasks in rural areas. A part of the argument towards rural photo voltaic is that power manufacturing is an inappropriate use of farmland and a nasty match for rural communities. Each of these points are undercut when farming can proceed and native ratepayers profit from decrease utility prices.
Keep watch over a neighborhood photo voltaic/agrivoltaic challenge referred to as Grafton Photo voltaic, situated at Knowlton Farms in Grafton, Massachusetts. AFT describes the 2-megawatt photo voltaic plus storage challenge as a “living laboratory” to discover finest practices for dual-use farming, with photo voltaic panels elevated a minimal of 10.5 inches above the bottom. The array was additionally constructed with extra space between the rows of panels, to allow farm gear to go by means of.
Together with AFT and BlueWave, different stakeholders within the challenge embody the worldwide power agency AES Company, the solar-plus-storage developer Borrego, the College of Massachusetts, and the main agrivoltaic companies supplier SolAg.
In a YouTube video concerning the challenge, AES signifies that its long-term curiosity includes balancing agricultural alternatives with the elevated value of supplies and development, so keep tuned for extra on that.
