“In the Netherlands, 5% of the solar installations fail due to technical faults or human error. If these failures are not monitored, a great deal of energy is going to be lost," says Christiaan Brester, director of LENS. LENS engineers, installs, finances, maintains and monitors solar installations on large roofs. According to Brester, the solar energy yields can be further optimised.

Affordable monitoring for solar energy installations

LENS has developed a data logger that makes the monitoring of solar energy installations possible in an affordable way. “The data logger can take readings from equipment such as solar energy systems. Data about capacity and technical faults is accessed and fed back to databases." The datalogger is combined with a second innovation. “When a district produces too much solar power, that can cause problems for the grid. We call that congestion. We can measure it with our system. In this way we can learn whether it makes sense to work with batteries and storage in the district concerned."

Cooperation accelerates the energy transition

Combining the two innovations is a costly process. “We cannot finance both of these processes. The subsidy will enable us to roll out a prototype that we can then test in the field". Together with housing association Woonbron, LENS is going to roll out the pilot at various locations. When it comes to sustainability, Woonbron is ambitious and expects the project to add to the ‘happy living’ of its residents. According to Brester, bringing the right parties together is essential for the energy transition. “In Rotterdam, you can see that steps are being taken. With the help of the Municipality, entrepreneurs are being put into contact with the right people. Partly thanks to this subsidy and the partnership with Woonbron, we can do more in a short period of time. That accelerates the energy transition.”
