Our solution

1,870 solar panels of 260 Wp provide a peak power of 486.2 kW. 15 pieces of SMA inverters STP 25000 transform this into alternating voltage. The flat-fix mounting set ensures a low weight on the roof and the new white roof covering ensures optimum efficiency.

Vomar Distribution Center.

Property type: Distribution center

Completion: 2016

The distribution center of Vomar Voordeelmarket in Alkmaar supplies 65 Vomar Voordeelmarkets. The enormous building, with a total area of more than 41,000 square meters, is an essential link in the company's business operations.

Our solution

Solar panels from Geothermal Energy Systems

The roof, with an area of 18,000 square meters, will be covered with more than 4,150 265Wp polycrystalline solar panels, equipped with 2125 SolarEdge P600 Power Optimizers. 31 SolarEdge 25 K inverters transform the generated energy into AC voltage. With a capacity of 1,100 MWp, the solar installation has a high efficiency and the energy load has been significantly reduced.

Range Alkmaar.

Completion 2017

For these shops for do-it-yourselfers, we have equipped various buildings with installations combined with 15 years of maintenance.

Rancid branches.

With 7 locations throughout the Netherlands, the branches of Ranzijn Tuin & Dieren have an enormous roof area. An opportunity not to pass up when your Fund is called the Zonnetje. ENTRAS works together with Hoorne Vastgoed, among others, to make new buildings and existing buildings more sustainable. With the solar project at the Ranzijn branches, 3,244 panels supply around 400,000 kWh of sustainable electricity annually.

A few years ago, the branch in Velserbroek was the first Ranzijn garden & animal with solar panels on the roof. The branches in Alkmaar, Amersfoort, Leiderdorp, Sneek, Spijk and Zaandam soon followed.

A great deal of research was required to make a sustainability idea a reality. Extensive technical research was the basis for the realization of this impressive solar project. Ranzijn is mainly located in greenhouses. This type of construction cannot be loaded indefinitely with the weight of the panels. With the input of sustainability experts from ENTRAS, we have been able to come up with a plan for the installation of a total of more than 3,200 solar panels at Ranzijn Tuin & Dieren. With the plan, Geotherm Energy Systems from Bunschoten was commissioned to install the panels.
