“In the field we notice that there is an increasing demand for solar panels. And especially the larger installations of 200 to 1000+ panels. Growers are increasingly realizing that they cannot stay behind and are thinking more about the future.” The Voshol Heat and Electrical Engineering team has noticed this. “It is becoming more important to produce in such a climate-neutral manner and alternative energy sources are indispensable, the (glass) horticulture must be made more sustainable”, says Jos Duijvesteijn.

This is also the case at Valk Rozen in Pijnacker. Here Voshol Warmte en Elektrotechniek installed 350 panels on the roof of the business premises. Optimizers were installed to increase the efficiency of the panels. These ensure that all panels work separately from each other. When one panel falls into the shade, this does not affect the rest and the other panels can achieve their maximum yield.

Roof direction and slope angle

In addition, the roof direction and slope angle also have a major effect on the yield of the panels. “A roof on the south with a slope between 30 and 40 degrees yields the most. But also a roof on the southwest or southeast with a slope between 20 and 40 degrees yields a lot,” Jos says. Growers can turn to Voshol for advice in the field of solar energy. “We then calculate what return you can achieve and whether it is attractive for a grower to invest in solar panels for his company.”
