Why is a home battery backup so important for photovoltaic power generation?

Photovoltaic technology is essential for the energy turnaround in the private and commercial sectors. Generating electricity from sunlight is now a proven and efficient technology that is reasonably available in our latitudes.

Many homeowners are already planning to use modern solar systems and lithium battery storage systems in their new buildings, while others are considering retrofitting. In any case, it takes a flexible and efficient solar home battery system to handle electricity that you don’t immediately consume or feed into the grid.

For years, high feed-in tariffs often made it more worthwhile to deliver power to the public grid than to consume it yourself. In the meantime, that has changed. Lower feed-in tariffs have made the concept less and less worthwhile.

At the same time, of course, we need power when there is no sun. Without a home battery backup system, homeowners would have to buy additional power at night or during bad weather, depending on their own power needs. However, traditional lead-based home battery backup have major drawbacks in terms of capacity, efficiency, and longevity.
