Agrisolar Park: Solar Panels on Farm Buildings
The Agrisolar Park supports solar power installations on the roofs of agricultural and agro-industrial buildings through a non-repayable grant, without the use of new land. It is designed for self-consumption, and this is where cost-effectiveness comes into play: a system that is oversized relative to the farm’s energy consumption loses much of its benefit. The program operates in phases: the 2026 phase closed in the spring, and no new openings have been announced. We support those who have secured the grant in carrying out the work, as well as those who are now considering a rooftop system, which must remain viable even without the grant.
Details of the measure
Agri-solar combines a system installed on existing rooftops with a significant government subsidy. Here's what really matters.
Roof-Mounted Solar Panels
Systems installed on the existing roofs of agricultural, livestock, and agro-industrial buildings, without occupying new land. This is one of the measure’s strengths, as it avoids conflict between land use and agriculture.
Non-Reimbursable Grant
Up to 80% of eligible expenses for primary production intended for the farm’s own consumption. This significantly reduces the amount of capital required, with priority given to those who have not already benefited from this program.
Self-Consumption and System Sizing
Cost-effectiveness comes down to this: the system must be sized based on the company’s actual energy consumption. Oversizing it relative to self-consumption negates much of the benefit, because energy fed into the grid is worth less than energy consumed on-site.
Related Projects
Where necessary, the measure also supports the removal and disposal of asbestos roofing, combining the installation with remediation. This is a benefit to consider in the overall assessment, given its impact on costs and timelines.
Windows and Times
The program operates on a first-come, first-served basis, by window: the 2026 round closed in the spring, and participants are currently in the implementation phase, with work to be completed within eighteen months of approval and final reporting by the end of 2028. No new rounds have been announced: an investment evaluated today must be viable even without a grant, with eligibility maintained should the program be refinanced.
What We Check
For demand to remain steady and the system to be effective, just a few factors matter.
Requirements for the measure
Suitability of the building and the business, documentation, and access requirements.
Self-consumption and size
The consistency between the plant's capacity and the company's actual consumption.
Affordability
The return, net of the subsidy, on consumption and actual energy costs.
Supplementary Measures
Asbestos removal and renovations, and their impact on costs and timelines.
How We Support You
We verify eligibility, size the system based on energy consumption, assess cost-effectiveness, and support the implementation of approved projects, preparing the company for any new windows on behalf of the property owner.
