Wereldhave is a Dutch listed company that invests in commercial real estate (offices, shopping centers and retail parks) in the Netherlands, Belgium and France. The company owns several shopping centers in the Netherlands
We have installed a solar energy installation on the roof of the Sterrenburg shopping center, which houses 36 shops. The specific thing about this project is that the solar panels have been placed on a recently constructed green roof, consisting of a layer of substrate in which sedum has been sown. Immediately after the construction of the green roof, Solnet Group started the solar energy installation with a peak capacity of 128 kWp.
A solar utility on a green roof requires specific adjustments. To provide the green layer, the sedum, with sufficient light, the solar panels are placed on a raised substructure. The minimum height between the panels and the sedum is therefore 40 cm.
In addition, the system is oriented to the south, in order to create more light for the plants.
The big advantage of the substructure that we use is that it is easy to install after a roof has been provided with a green layer. Many other systems on the market require that the substructure for the solar panels be installed first, after which the green layer can be laid. In principle, we can provide every green roof with a solar utility, including regular ballast blocks. This makes installation simpler, faster, and more economical. The system has also been tested in a wind tunnel and has been certified.
Delivery of solar power to tenants
A unique project with a good yield and one of the first installations in the Netherlands that was built in this way. Solnet is currently developing several retail locations for this customer.
In addition, we advise Wereldhave on how best to monetize the investment in the solar utility by supplying the produced solar energy to their tenants.
An intelligent solar power plant with 900 kWp. After its completion, K-citymarket Länsikeskus was the largest solar power plant in Finland
The intelligent solar power plant with 50 kWp generates electricity for the ventilation and lighting of the Länsisatama passenger terminal
236 kWp Smart Solar Utility at the headquarters of the insurance company Ilmarinen is the largest site-specific installation in Helsinki
The panels supply 16% of the annual electricity consumption of the buildings. At peak production, the system delivers up to 60% of the current electricity consumption.
