Photovoltaic Energy Storage

Solar Electrical Energy Storage: Key to Energy Independence

While photovoltaics ensure clean energy production, battery systems enable you to efficiently use this energy exactly when you need it.

Smart Solar Energy Storage: Principle and Benefits of Battery Systems

How Does Energy Storage Work During the Day?

During sunny days when your photovoltaics produce the most electrical energy and you cannot consume it, you can store it in batteries instead of disadvantageous supply to the distribution network.

Utilization of Stored Energy When There's No Sun

In the evening, at night, or during less sunny days, you then draw from these stored reserves as needed. The battery system works similarly to a power bank for a mobile phone, only on a significantly larger scale – it creates an energy reserve that allows you to be independent from grid supplies for extended periods.

Intelligent Control of Modern Systems

Modern storage systems can also intelligently manage energy flows, optimize charging and discharging according to your needs, and thus extend the lifetime of the entire system.

Why Invest in Energy Storage?

Investment in electrical energy storage represents a strategic step towards achieving true energy self-sufficiency.
