Agrivoltaics

Pine Gate Renewables has announced plans to deploy 9 MW of solar and 36 MWh of storage above a commercial cranberry bog.

The solar greenhouse was built by French developer Tenergie in 2017 and last year recorded a remarkable performance in terms of both agricultural ane electricity yield.

A 1.2 MWp installation featuring more than 4,500 solar panels has sheltered a berry crop from high temperatures and damp to strengthen the claims made by agrivoltaics companies that their systems can offer climate change mitigation as well as clean energy.

The German renewable energy developer has already identified two potential partners, a beekeeper and a sheep breeder, to exploit 20 hectares.

Researchers in Germany have stated that agrivoltaic projects are still considerably more expensive than ground-mounted PV plants. They found the agrivoltaic developers may incur higher costs during the approval process or due to design constraints. Furthermore, the use of special components such as modules, mounting systems and trackers may significantly increasing a project’s cost, especially if vertical plants are planned or the modules must be elevated to let the agricultural machinery operate underneath.

German energy company Steag wants to build three PV plants totaling 244 MW across several olive groves in the southern Italian region of Apulia. The unsubsidized agrivoltaic projects are expected to sell electricity through power purchase agreements. The distance between the rows of the olive grove and the photovoltaic system has been specifically designed both to avoid shadowing and allow the passage of the automatic machinery necessary for the cultivation of the olive trees.

German tracker manufacturer Ideematec has adapted its Horizon L:TEC tracker for a series of agrivoltaic projects totaling 100 MW that will be developed in France by Spanish developer Amda Energía. The new tracker is claimed to be able to operate synergistically with the agricultural equipment.

Spain’s Tranesol is setting up two energy communities that will be powered by 2.5 MW of agrivoltaics. The two facilities will be located in the Valencian Community, which is at the forefront for supporting projects for solar power sharing.

According to new guidelines by Germany’s Fraunhofer ISE, agrivoltaic projects are already competitive with other renewable energy sources today. The lack of a proper regulatory framework, however, is currently preventing the dual use of arable land for food production and power generation from becoming a mainstream solution.

Both solar and the farming industry are beginning to see potential in the combined use of land for food production and energy generation. And as innovators begin to experiment with different forms, it’s becoming clear that in most cases it is solar that will have to bend to the needs of agriculture, and not the other way around, to ensure a positive outcome.
