Overview

Innovation with the Implementation of a Rotational Grazing System for 50 Ewes.

With the single Class 2 permit secured, the agrivoltaic project in Soleilmont is under development and is expected to be operational in 2025. In partnership with a local farmer, 50 ewes from a farm in Gerpinnes will have the opportunity to graze under and between the 9,200 photovoltaic panels.

The 5.7-hectare project is located in the municipality of Fleurus, between the R3 and the Bois de Soleilmont, in a field on Rue Joseph Daye in Heppignies. This pasture is situated in a sectoral plan’s extraction dependency zone. The energy project promotes a new agricultural technique – dynamic rotational grazing – much to the delight of local farmers.

Dynamic rotational grazing involves dividing a plot of land into multiple parcels separated by fences, allowing the 50 ewes to move from one section to another. This method helps preserve soil fertility and promotes better grass regrowth, ensuring higher nutritional value for the ewes, whose meat is intended for short supply chain sales.

The fixed solar panel installations (zero concrete technology), raised 1 meter off the ground, will allow the ewes to move freely while coexisting with the solar panel rows. The panels will occupy 2.4 hectares of the total project area.

Challenge

Agricultural Transition

The land will be extensively used, without chemical inputs, hosting around 50 ewes on 5.7 hectares. The meat produced will be sold through short supply chains. The solar panel installations, raised to 1 meter, will allow the ewes to move comfortably between them while providing shelter during extreme heat or harsh winter conditions. The rotational grazing system will consist of three fenced zones. Selected forage crops will mainly include a variety of grasses and clovers, well-suited to shaded environments and offering high forage value.

Environmental Transition

The agricultural project includes planting a hedge along the western boundary of the site, covering approximately 445 meters, with species similar to those already present. A carefully selected mix of plant species will ensure a protected habitat for birds (thorny species) with the support of "Yes We Plant." Additionally, 1.2 hectares will be designated as an extensive meadow to enhance biodiversity potential and wildlife habitats, creating a transition between open and forested environments.

Solution

In response to current global changes, an energy transition policy has emerged, emphasizing the development of renewable energy sources.

The Soleilmont project will produce electricity for 30 years, starting in 2025, generating 6,000 MWh per year—enough to power approximately 3,000 households. The project is also compatible with a Renewable Energy Community. Discussions are ongoing with public and private entities to identify businesses interested in purchasing green energy, ensuring a local and sustainable electricity supply chain.

Additionally, this initiative supports the revival of the sheep farming sector in Wallonia, which has faced challenges in recent years.
