New software modeling tool for agrivoltaics – pv magazine International


Sandbox Photo voltaic, a photo voltaic developer and US federal grant recipient, has launched a beta model of its software program modeling software for agrivoltaic energy crops. It helps the design and optimization of photo voltaic panels, in addition to backside crops.

Agrivoltaics, the mixing of meals manufacturing and photo voltaic vitality, is a brand new know-how that makes higher use of the restricted assets of land and soil. As a result of the business continues to be younger, there may be not but a straightforward web-based software like Aurora or Helioscope to assist photo voltaic builders rapidly arrange designs, making an allowance for the crops beneath.

Sandbox Photo voltaic, a photo voltaic contractor, has developed such a software, referred to as Spade. Spade goals to assist photo voltaic builders to find out the most effective plant sorts and photo voltaic panel layouts for his or her tasks. The system made it into the fifth and closing section of the Division of Power’s “American Made” photo voltaic retrofit program. An early Beta Model of Spade is now accessible, and it’s already getting used to develop solar energy tasks paired with potatoes, hemp, hops and different crops.

The software program generates a number of key numerical outputs: irradiance, in addition to photosynthetically energetic radiation (PAR) and common photosynthetic photon flux density (PPFD), that are two forms of mild measurements which can be much less acquainted within the photo voltaic commerce.

PAR refers back to the vary of wavelengths helpful for photosynthesis, whereas PPFD measures the density of photons inside that vary that attain a selected floor space. Not all wavelengths of sunshine are equally efficient in photosynthesis; Vegetation typically use blue (400 nm to 500 nm) and crimson (600 nm to 700 nm) mild extra effectively than inexperienced (500 nm to 600 nm) mild. PAR and PPFD are each necessary for understanding and optimizing mild circumstances for plant progress and photosynthesis.

The knowledge is displayed visually by means of charts, and numerically, as watts per sq. meter and PAR/PPFD values. Additionally, PAR is the quantity of helpful mild that reaches the crops rising between the photo voltaic panels. Most agrivoltaic-compatible crops truly profit from the discount in irradiance provided by the shade of photo voltaic panels.

Spade’s group informed us that the essential strategy to optimizing agrivoltaic tasks entails addressing the three C’s: configuration, local weather and crops. By fastidiously contemplating these components, a developer can refine their methods by spacing and mounting photo voltaic panels to maximise land use, making certain the absolute best steadiness between the era of vitality and agriculture.

The graphic under captures Spade designer Tom Hickey’s altering inputs to photo voltaic designs, which then outputs varied potential outcomes of photo voltaic designs that meet the venture’s necessities. Hickey has been with Sandbox for over 5 years, and at the moment works part-time on the Nationwide Renewable Power Laboratory. He straight makes use of Spade in design work for Sandbox’s clients and agrivoltaic tasks.

“Spade modified what I did at dwelling,” Hickey mentioned.

In a latest dialog with pv journal USA, Alexis Pascaris – a Spade software program growth lead – famous the Massachusetts agrivoltaic program and the distinctive incentives discovered within the state’s SMART photo voltaic program. With Hickey and Pascaris operating the processes, Spade works with builders as a subcontracted skilled who coordinates with the Division of Agriculture to maneuver tasks by means of the SMART software course of. Pascaris advised that Spade’s shadow detection instruments are extra correct than the instruments at the moment mandated in Massachusetts.

Ian Skor, the founding father of Sandbox Photo voltaic, mentioned he believes that the present iteration of the software is powerful sufficient to satisfy the instant wants of the corporate and its consulting purchasers. Nonetheless, he acknowledged that there’s room for progress in frontend software program growth to facilitate improved on-line interactions and refine its total performance.

Alexis mentioned the corporate is growing a finances for taking Spade to the subsequent stage, to allow them to start a request for funding proposals someday in 2023. Presently, the group doesn’t have any absolute put in tasks developed with Spade. Nonetheless, a number of Spade-designed tasks are slated to start building quickly, together with an in-house vertical bifacial venture.
