Industrial multi-sites, business parks, municipalities, property owners: RaYSun designs, builds and runs dedicated energy communities and sharing operations in every region. And it already works — quantified proof below.
Share energy between your own group's buildings: the production of one or more sites powers all the others.

The Multi-site & Ecosystem model lets a company turn its solar surplus into value by sharing it directly between its operating sites, while opening the sharing to its trusted ecosystem: employees (at their main residence), sister companies, subsidiaries, business partners or key suppliers.
The project owner remains in full control of governance: you decide sovereignly which entities and people are admitted to your exchange perimeter, the energy allocation key and the applied tariffs.
The result: maximum optimisation of your self-consumption rates, a drastic reduction of your overall bill, and an innovative partnership and social advantage at the scale of the Walloon Region.


Walloon quarries and cement plants connected with their partners: the first major industrial player to create its own sharing operation.


26 stores and logistics centres switch from an individual to a collective logic.


The solar surplus of the producing sites powers all the group's buildings.


The centres in Eupen, Baelen, Alleur, Jemeppe and Chaineux share the surplus of their producing sites.


The group's producing sites power the other buildings and their partners.


The sister operation on the Walloon side: all the region's Facq sites in a single sharing operation.
On a business park or in a municipality, companies and public services share among themselves and reinvest in new panels. More resilience, more local roots, more green energy — and more savings.


The business park's entrepreneurs share their electricity: Goossens, Destexhe, Polycar, Ampi, SPS and their neighbours.


Buildings owned by several parties — industrial players and builders in the lead — share their surplus with the business park's consumers: nearly half of all needs covered locally.


Schools and social-services buildings share the municipal solar production — a first step before opening up to citizens.


11 public buildings — town hall, sports centre, crèches, schools — make the most of municipal solar production.


Two production sites, their neighbours and their employees: sharing rooted in the Bocq valley.
Roof owners without their own consumption: you install panels and the energy is shared with your tenants — or even with consumers across the region. A valued asset, loyal tenants.


The BuzzyPark developer fitted the roofs with 239 kWp; the park's 8 tenant companies consume the energy produced on site.


964 panels on the roofs of Aalst and Haaltert: the property investor shares 421 kWp with its tenants.
