New feed-in regulations in the Netherlands require a rethink

Since the summer of 2024, new feed-in regulations have been in effect in the Netherlands, making it essential for PV system owners to maximize their self-consumption of solar energy.

The so-called “terugleverkosten” (feed-in charges) impose annual costs of between €100 and €800 on PV system operators who feed surplus electricity into the public power grid.

A Dutch electrical engineer is owner of a renovated farmhouse equipped with a 14.4 kWp photovoltaic system, was faced with this challenge. Aware of the new feed-in charges, he sought a way to reduce these costs by minimizing the amount of electricity fed into the grid. Naturally, the lower the amount of excess electricity fed into the grid, the lower the associated fees.

Using PV surplus for hot water

The homeowner found his solution in utilizing the surplus PV energy for hot water production. He opted for the AC•THOR 9s from my-PV, a linearly controlled photovoltaic power manager that converts surplus solar energy into heat – for hot water with photovoltaics and optionally for heating with photovoltaics.

Before installing the AC•THOR 9s, the PV system fed over 5,600 kWh of surplus electricity into the grid annually. After switching to PV-powered heat, a significant portion of this energy is now used for hot water production, substantially reducing the amount fed into the grid. With every kilowatt-hour of solar energy he now uses himself, he not only minimizes his feed-in charges but also enhances the economic efficiency of his PV system.

How can feed-in charges be reduced through high self-consumption?

We have simulated simple yield data to illustrate the potential feed-in charges in the Netherlands and provide an explanation of how customers can avoid these fees by using their surplus PV electricity for hot water production. Read more here.
