Solar Energy Magazine – Project of the Week

In its “Project of the Week” section, Solar Magazine gives a weekly interest in a special solar project. This week’s A1 solar field at the Deventer exit, built on behalf of Rijkswaterstaat.

When Pure Energie completes construction of a 0.85 hectare solar lawn along the A1 near Deventer at the end of this month, 30 kilometers of the highway will be energy neutral for the next 16 years. The solar panels produce enough power to cover the power consumption of the matrix panels, lighting and art installations along the A1 between Twello and Rijssen.

Light and rain water
The solar lawn will be built in the armpits of the new Deventer entrance and exit, which will in turn be carried out by construction company Heijmans on behalf of Rijkswaterstaat. Within the tender for the “A1 Expansion” project, this made room for sustainable energy generation.

To give this even more shape, construction company Heijmans, as the main contractor for the project, has entered into discussions with Pure Energie and the idea for a solar garden has been created in the inner ring of entrance and exit 23. Rebuilding this entrance and exit creates space that would normally be used almost exclusively for storage water. The site appears to have a dual use: water storage and sustainable energy generation in the form of a small solar garden.

Solar panels at Zonnepark A1 in numbers

manufactured solar panels: Lungi Solar
Number of solar panels: 1400 pcs
Solar panels feature: The solar panels have a peak capacity of 415 Watts, are installed with mounting materials from Sunprojects in a southern arrangement, and are connected to two Huawei inverters of 215 kilowatts.
installers: Heijmans and Pure Energy.
Specifics: The production of solar panels is enough to fully offset the energy consumption of A1 on the Twello-Rijssen road – about 500 MWh per year.

green hedge
The design of the solar park is in line with the redesign of the entrance and exit to and from the A1 near Deventer. The solar panels are in a southern arrangement with a space between the rows and oriented towards the south. This allows sufficient light and rainwater to reach the soil, making the bushes possible. The wide ridged ditches and canals surrounding the solar park provide plenty of water storage space. Also along the edges is a green hedge with a fence. In this way, any light glare from the solar panels is protected from motorists and local residents.

A solar park at a crossroads where many links meet. Where expectations were discussed, what was said was carried out quite simply, but not simpler, says project leader Michael Lermakers of Pure Energy. “The use of mobile crash barriers to direct traffic in a safe manner is a stark example of this.”
