Project of the week | Zonnepark Geertjesgolf of Solinoor: 100 percent local consumption in grid congested area

In a grid congested area without the possibility to return to the grid , Solinoor has built a 4.2MWp solar park on a landfill to provide a local sand extraction site with renewable solar energy. Given the challenges of the soil on this old dumpsite, a new innovative mounting structure was used to build this project. 

In the Project of the week section, Solar Magazine devotes weekly attention to a special solar energy project. This week Solar Park Geertjesgolf van Solinoor, realized in an area where there is grid congestion.

The Geertjesgolf project area is located between the Ewijk junction at the A50 and N322 and the villages of Deest and Winssen. In this area sand extraction Geertjesgolf extracts clay, sand and gravel. In the meantime, the area is gradually getting a new face as a living and recreational area for humans and animals. The ultimate goal is 100 hectares of water, 25 hectares of marshland, 17 hectares of herb-rich grasslands and 5 hectares of forest.

Solar energy
But it doesn't stop there, because plenty of solar energy is also generated in the area. Together with Zandwinning Geertjesgolf, Solinoor has converted an old landfill site into a sunbathing area in the area.

“Because the solar park is located on an old landfill, we used a new, innovative design for the foundation and cabling,” says Vahid Kharidar, co-founder and director of Solinoor. 'By cleverly attuning the techniques to the circumstances of the project location, efficient use can still be made of an otherwise unused piece of land.'

The solar panels of Zonnepark Geertjesgolf in figures

Solar panel manufacturer: DMEGC Solar

Number of solar panels: 7,639 pieces

Solar panel characteristics: the solar panels have a capacity of 550 watt peak each

Inverters: 13 Sungrow inverters, type SG250HX

Mounting system: a new concrete foundation/mounting system has been used because of the maximum depth of 30 centimetres.

Power control
“In our projects, we have the ambition to look as much as possible at local solutions,” continues Kharidar. ‘With network congestion becoming an increasingly common problem, we include the local environment in project development in order to form an idea of what the best past is for each project. In this way we coordinate local production of sustainable energy with the use of local measurements. At this solar park we use an innovative and working "power control" system. With this system we have the energy production of the solar park and the energy of the power grid in order to match the consumer profile of sand-winning Geertjesgolf. All solar energy generated by the solar lawn is used directly for sand extraction.'
