More than 420 000 photovoltaic systems (PV) have been installed in private households in Belgium and a majority of them are billed through a net metering scheme. With net metering, a household with a PV system will only be charged the difference between the solar energy fed into the grid and the energy drawn from the grid. However, the Belgian government has changed its regulations and will now offer a subsidy for residential storage. The subsidy was launched in Flanders at the beginning of 2020 and it offers households who install energy storage a subsidy of up to €3200 as Belgium transitions towards a decentralised energy supply.
The sonnenBatterie 10 is a modular home storage system with an output of 4.6 kW. The smallest version starts at 5.5 kWh and can scale up to 27.5 kWh. For commercial applications, the sonnenBatterie 10 can also be configured for up to 247.5 kWh.
sonnen uses only lithium iron phosphate battery modules, which are free of toxic heavy metals and cobalt - a conflict raw material. In addition, they are particularly safe and durable, which makes this an ideal energy storage technology for virtual power plants. sonnen guarantees a performance of at least 10 000 charging cycles.
