Sundust specializes in  planning and financing commercial solar installations

Modern Office Building


We help companies and commercial real estate owners transition to CO2-neutral energy supply with solar power. Working closely with solar installers, we plan and finance high-quality photovoltaic systems at our customers' locations and deliver solar electricity at lower tariffs compared to conventional supply. Assuming the operational and financial risks of the photovoltaic system, we offer a comprehensive solution with ecological and economic benefit.
