Intelligent energy solutions for businesses
Lower your energy costs with solar and storage solutions sized to your business. You use the electricity you produce, and we handle design, installation and service.
A turnkey solar system for your business
Your business buys the system and uses the electricity it produces. Every kilowatt-hour from the roof is a kilowatt-hour you do not buy on the market.
Solar Direct for businesses
Solar system for your hall, office building or farm, optionally with battery storage and EV chargers.
Since 2026, businesses use the active customer status. The value of the system is the electricity you use yourself, at the price you would otherwise pay for it.
Why FreeState?

Predictable energy. No surprises.
You produce electricity on your own roof and depend less on bills and price rises.
One system. Maximum efficiency.
Solar, storage and e-mobility, perfectly aligned.
All-round service. No hassle.
