Additional revenue for Solar Power investments with battery storage
A battery storage system helps your solar power production and consumption align even better. Electricity can be purchased in addition to your own production when it’s cheap. Stored energy can be used for your own consumption or sold to the market, depending on which provides the best economic benefit. Our energy storage systems also enable participation in reserve markets.

As our customer, you receive battery storage systems suited to Finnish conditions, fully installed and ready to use. The battery storage operating temperature range is -30…+50 °C, so it can be installed directly outdoors. We take care of everything from foundations to installation and commissioning.
