Solar power for our shops and central buildings

Our shops’ opening hours correspond well with the hours that the sun shines. That’s not only handy when you come to shop with us, it's also practical for our energy supply. Wherever it’s appropriate, we can use self-generated solar power to provide our shops with electricity. Solar panels produce most energy during the day when demand for electricity is also the greatest. And of course, they don't emit any CO2.

More than 40 shops and 8 central buildings

Eoly owns and manages more than 50 installations on distribution centres and Bio-Planet, Colruyt and OKay shops. The solar panels generated 5,430 MWh in 2016, the equivalent of the annual energy consumption of 1,552 households. Eoly will further expand its number of installations in the future.

In addition to solar energy, we also use other technologies to produce green energy: 

With new shops, we always investigate whether it’s a good idea to install solar panels.

We base the number of solar panels on the building’s energy consumption

Matching production to demand

Our energy specialists have made a conscious decision not to install solar panels just anywhere. “For the simple reason that it’s not always suitable,” says Jeroen Martens, operations & maintenance manager at Eoly. 

“Before we install a single solar panel, we analyse how much energy the building needs. So we always investigate whether the solar panels are technically and economically feasible. We do this because the electricity consumed on site becomes cost-efficient. This means that we never install more solar panels than we need to cover the site’s energy requirements. So on sunny days, the shops can run almost entirely on solar power. Another advantage is that we need to transmit the minimum possible surplus energy to the grid.”

Solar panels on shop
On sunny days, some of our shops run almost entirely on solar power.
