Solar energy generation is one of the key initiatives through which Royal A-ware contributes to reducing greenhouse gas emissions. However, beyond emission reduction, energy storage enables us to strategically utilise solar power during peak demand periods, enhancing overall efficiency.
Since 2024, a state-of-the-art solar installation has been in operation at Royal A-ware's packaging facility in Almere. This system comprises 4,458 solar panels powering seven high-capacity batteries. 'By converting sunlight into electricity, we demonstrate Royal A-ware’s commitment to sustainability,' says Berry Vrijhoef, project engineer. ''Additionally, it enables us to operate within the limits of our contracted energy capacity.'
Energy buffering
The first use of generated solar energy is for charging batteries. Berry: 'By buffering the energy, we can use it later at peak times. In summer, for example, we use a lot of electricity for the cooling systems. Another peak demand time can occur when doors are open for longer periods while loading trucks in hot weather. The warm outside air flowing in must then be cooled. We are trying to optimise this truck-loading process so that we are as energy-efficient as possible.'
Once the batteries are charged, the remaining solar energy generated goes to the equipment, reducing the need to draw on electricity from the power supplier. Berry: 'Think of cooling systems, equipment for cutting and packaging cheese, compressed air systems and vacuum systems. Solar energy can also be fed back to the grid.'

Innovative
Ultimately, how much does a solar installation yield? 'Theoretically, with favourable weather conditions, we could generate about 11 percent of our annual energy consumption each year ourselves. 'Although the generation profile of solar panels over a calendar year is erratic and therefore difficult to predict,' Berry said. 'Of course, we're dependent on the weather. Between April and September, the generation rate was estimated at 78 percent of total consumption. This is precisely during the period when we need extra energy for the cooling units, for example.'
Royal A-ware is proud to contribute to sustainability in this innovative way. We reduce CO₂ emissions and energy costs, while at the same time increase the reliability of a stable energy supply.
