Technical FAQs 4

What is solar power storage?

Strictly speaking, solar power storage is not just a battery but a rechargeable solar battery. In case of strong solar radiation the generated solar energy exceeds the energy demand of the house. The excess energy is passed into the solar battery and charges it, like a battery.

What is a solar container?

Our Solar Containers are designed in a way to maximize ease of operation. It’s not only meant to transport PVs but also to unfold them on site. It is based on a 20’ sea container. The efficient hydraulic system helps quickly prepare the Solar to work. Because of their construction, our containers offer unmatched flexibility and mobility.

What is solar storage capacity?

The nominal storage capacity is the amount of energy that the solar storage can maximally absorb. The actual usable capacity multiplies this value by the discharge depth and is thus more meaningful. During charging and discharging, the solar battery emits heat to the environment. As a result, part of the stored solar power is lost.

Why do we need a large-scale battery storage system?

They ensure the stability of transmission lines and reduce energy costs through the use of photovoltaic energy and large-scale battery-storage systems in hybrid power generation systems. Large-scale storage solutions from SMA for a stable, flexible and efficient energy supply.
