Self-consumption optimization

Consume more of your own solar power.

A battery storage system shifts excess solar energy to the hours when you actually need it – for less grid consumption and more independence.

What is a funding contribution?

During the day, the storage system charges with excess PV energy. In the evening, at night or during times of high consumption, it automatically provides this energy. An intelligent energy management system coordinates the PV system, household, heat pump and e-car. This is economically worthwhile because every kilowatt-hour consumed for own use replaces the purchase of grid electricity and thus generally achieves a higher value than the remuneration for fed-in solar electricity.

Your advantages: higher self-consumption, lower electricity costs, less dependence on the electricity market and transparent energy flows.

What are the concrete benefits of self-consumption?

Every kilowatt-hour fed into the grid that you use yourself instead saves the difference between the electricity price and the feed-in tariff. Enter your values.

Important information

Important information

Check the conditions in the regulations. Technology, capacity, ownership, proof, and whether second-life components are considered additionally or separately.

Use solar power from the day in the evening, reduce grid consumption and get more out of your own PV system.

E-Mobility & Load Management

Charge e-cars in a solar-optimised way, protect the house connection, and intelligently coordinate heat pumps, storage units and wallboxes.

Emergency power & higher self-sufficiency

Continue to supply critical consumers during power outages and selectively reduce dependence on the public grid.

Trade

Using your own solar power where it relieves the burden on operations.
