Solar energy has grown significantly, space on the power grid is a ‘bottleneck’

More than 9 percent of the total electricity consumption in the Netherlands was generated by solar panels last year. Although the RVO also predicts growth in the coming years, the limited capacity on the electricity network is becoming a problem in more and more places for the construction of new solar panels.

Solar energy is important to the government, which wants to reduce CO2 emissions by 60% by 2030 compared to 1990 in order to limit global warming.


Almost two thirds of the power from new solar panels comes from the subsidy for sustainable energy (Stimuleringsregeling Duurzame Energieproductie, or SDE). According to the RVO, approximately 60 percent of the solar panels are in large installations.

Even if this subsidy may no longer be applied for for the installation of solar panels in a few years’ time, the ‘sun market’ will still continue to grow, the government expects.

Busy on the power grid

Since 2019, the RVO has noticed that more projects for which SDE has been applied for are not or not fully realized. This is partly because, for example, a roof structure on which solar panels would be installed, on closer inspection, is not suitable. But the pressure on the electricity network often gets in the way. There have been problems with the electricity grid for some time: because there is more renewable energy, sometimes not all electricity can be transported through the electricity grid.

Small consumers also experience temporary shutdown of their solar installations due to voltage problems or long delivery times when applying for a new or modified grid connection.

How much electricity can ultimately be generated by solar panels ‘depends on the extent to which solutions are found for bottlenecks’, including the limited grid capacity.
