Get a solar plant without investment

We help companies to switch to a CO2-neutral energy supply with solar power. We take over the financing and operation of photovoltaic systems at our customers' sites and supply solar power at lower tariffs than those paid for the conventional supply. The system is installed by the solar installer of your choice or by a Sundust partner company. We bear the operational and financial risks and offer a complete package with ecological and economic added value.
