SOLON presents the new SOLON SOLiberty energy storage system. It allows owners of photovoltaic power systems to cover up to 70% of their annual power consumption and be less dependent on power supply companies. The system has a capacity of 24 kWh, allowing it to cover the average daily power consumption of a family of four. SOLiberty by SOLON is a low-maintenance, reliable and stable storage solution offering good value for money to consumers who want to stop being dependent on rising electricity prices and contribute their share to the energy revolution.

SOLiberty was developed by SOLON and Deutsche Energieversorgung GmbH, whose expertise, bundled under the SENEC.IES brand, has helped decisively to optimize the battery. The system consists of a storage block with 24 lead battery cells connected in series and a switch cabinet with the corresponding electronics. To ensure a safe and stable power supply, the storage management system draws power from the public grid if the solar power system or the batteries cannot supply sufficient energy. The battery also has protection against deep discharge. This increases the lifetime significantly.

The energy management system is designed primarily for own consumption. Solar power is only fed into the public grid once the battery storage is full. SOLON SOLiberty can be installed on existing systems or be installed together with a new photovoltaic system. Installation is quick and easy. The battery has an approximate lifetime of 10 years; the remaining capacity after this time is 80%. The system is produced in Germany. SOLON gives a product warranty of six years and a performance warranty of ten years. SOLON SOLiberty will be available in the first quarter of 2012.

“We want storage of electricity to pay. This is why we offer our customers this crisis-proof investment, which also pays more than your average savings account,” says Dr. Lars Podlowski, CTO of SOLON SE. Consumers profit in several ways from solar storage systems. They receive the German subsidy for self-consumption and the additional feed-in tariff for excess electricity fed into the grid. And, of course, their normal electricity bill is also lower. Considering the rising prices for electricity, storage and self-consumption is becoming more and more attractive in the long run.
