Two roofs full of solar panels
It is an impressive sight. On the roof of Nedlin Healthcare and Hospitality in Elsloo there are 2500 solar panels shimmering in the light. On top of the new laundry facility of Nedlin Industry in Hoensbroek there are another 760 panels. Together, they have already realised a CO2 reduction of 283,000 kg in a few months’ time. Björn Frijns will tell you more about it.
Frijns, Director Technical Affairs, has been working at Nedlin for over 20 years. With experience as operations manager at Hospitality and plant manager at Industry, he has been in charge of innovation and new developments at the company for a year now. The 3260 solar panels are his responsibility as well. It is a large number, he agrees. Placing all those panels was a big job.
“First we prepared everything, up to the finest details”, says Frijns. “The locations for all the panels were accurately marked on the roof. There should be no shade on them, so they had to be installed carefully around every pipe and chimney.” With frames on the roof the angle is optimised. This way the solar panels will be the most effective.
Because of the placement of the solar panels, 22% of the power that Nedlin uses in Elsloo is solar power. In Hoensbroek it is even more than twice as much. Here, solar power covers 50% of the energy demand. A monitoring system in the laundry facility measures the actual revenue of the solar panels. The system calculates how much CO2 emission Nedlin saves every day, by using solar power. “The CO2 reduction that we have realised in only five months, is equal to 18,500 trees”, Frijns declares proudly.

Every year, the solar panels in Elsloo should yield about 890,000 kilowatt hours. For Hoensbroek, the prognosis is 270,000 kilowatt hours per year: just as much as the consumption of about 420 households. Frijns: “Our supplier gave us a prognosis for the full year. During the winter months the revenue is the lowest, but the efficiency a little higher. The panels perform the best when it’s cold and the sky is clear. But because the days are shorter then, you need the summer season for the best results”.
The solar panels fit the sustainability ambitions of Nedlin. “We’re just trying to as diligent as possible”, says Frijns. “We limit our water consumption as much as possible, and are economical with energy. We do our best to give heat sources proper isolation. And in order to maximise productivity, we minimise operational times. For example, rather than letting 2 people work for 4 hours, we prefer to let 4 people work for 2 hours. This will also save energy.”
Our philosophy is: treat the environment well. And we really put in the maximum effort for this goal.
This was also the biggest motivation for installing the solar panels. “Our philosophy is: treat the environment well. And we really put in the maximum effort for this goal. There’s no more space for even one more solar panel.”
- 1160 MWh Total solar power output on an annual basis
- this is equivalent to the consumption of 1805 households
- 627 tons of CO2 savings on an annual basis
