We want more solar power, but it should not overload the grid and should preferably be used close to home. Germany has a solution: up to 10,200 euros in subsidies if you purchase panels, a home battery and a charging point for your e-car.
In the Netherlands we are struggling with the enormous success of solar panels. The local power grids cannot cope and due to the oversupply of electricity during sunny hours, the price per kilowatt hour regularly drops below zero, which costs energy companies money. So the call for home batteries arises. This allows you to store your solar power in your battery during the sunniest hours and in the evening you use that power to cook, watch TV or charge your car.
Flanders has had a subsidy scheme for home batteries for some time. Or no: had such an arrangement. Because it was abolished in April. Home batteries are so expensive that you cannot recoup them even with subsidies. Few people are enthusiastic regarding that.
Three flies
Germany will take a slightly different tack from next week. They hope to make the home battery attractive with a combination of things. You can receive a maximum subsidy of 10,200 euros if you purchase solar panels, a home battery and a charging point for your car at the same time. Then you can charge your car battery directly at home during the sunniest hours or, if the car is not there, charge your home battery and later put the power from it into the car battery.
Germany hopes to kill three birds with one stone. More solar power is generated; it places less strain on the grid; and electric cars will consume less gray energy from the grid and will run more on green energy from their own roof.
For higher incomes
To achieve this, there is a scheme whereby you receive a subsidy of 8,000 euros for an installation costing, for example, 32,000 euros, or almost a quarter. In practice the ratio will be more favorable, because I think Germany estimates the costs too high. All in all, the subsidy (which does not depend on the purchase prices but on the capacities of the three components) is closer to 40 percent of the purchase costs.
It seems like a smart scheme that does indeed encourage the purchase of solar panels and the use of electricity at home and in your own car as much as possible. But I don’t think the Netherlands will copy the scheme following all. For example, Germany requires that the subsidy applicant owns the house on which the panels are installed and that he already has or has ordered an electric car. This makes it a scheme for the more affluent. In the Netherlands we also want sustainable energy to benefit lower incomes.
It also remains to be seen whether the combination has the intended effect. A home battery of 12 kWh, the maximum for which you receive a subsidy, is relatively large, but if you have a lot of panels on your roof, it will be full in one or two hours. After which the power grid is still heavily loaded.
V2G on the horizon?
An intriguing part of the scheme is that the subsidy for a charging station is 600 euros, but 1200 euros is available for a bi-directional charging station. These are charging stations that can charge car batteries via the so-called Vehicle to Grid (V2G), but can also supply power from the car battery to the grid. Anyone who follows me knows that I would like to have a car and charging station for V2G as soon as possible. However, those cars are not available yet. But perhaps the German government has been told by its car manufacturers that those cars are really coming. A subsidy on those cars might relieve the grid much more than the combination that Germany is currently pursuing.

Network company Liander advocates quickly abolishing the netting scheme and encouraging home batteries in return. The grid can no longer handle all the power from solar panels and home batteries actually relieve the grid, is the logical reasoning. But I don’t think this logic is smart.
