Self Consumption

In general, the amount of solar power produced does not match the amount of electricity used in the household. In particular, power consumption will
exceed own production in the morning and at night, and also during the winter months. By shifting household consumption into the high phase of solar power production, it is possible to increase the consumption of self-generated electricity.

Washing machines, dryers and dishwashers can easily be operated during those periods using simple technical tools such as timers. Automated solutions for intelligent device management, such as the Sunny Home Manager, make it possible to increase the internal consumption rate by approx. 15%. The use of storage systems, which store excess energy and draw on it as required, can increase this rate to up to 70%.

Electricity rates rise every year, continuously. At the same time, the number of electrical devices in household increases annually. As a result, the electricity bill of the consumers becomes more and more expensive.
The claim that feed-in tariffs raise the prices for electricity is not true. Feed-in tariffs decrease continuously.

Rising electricity prices make self consumption profitable – even for a one-person household.
Thanks to device management and storage systmes the percentage of self consumtion can be even improved.
