Maximise independence

Retrofit solar storage: save on operating costs

Reduce electricity costs and operating costs effectively by adding a battery to a solar system.

More independence thanks to the solar system's battery storage

The advantage of a storage unit for a solar system is obvious: enormous savings can be achieved by using solar power irrespective of the time of day and independently of energy suppliers. But retrofitting a solar storage unit offers even more advantages.

Retrofit solar storage: achieving more independence

Particularly in the industrial sector, retrofitting a storage system can result in significant cost savings if the electricity produced by the company itself can also be used during night shifts or in the early hours of the morning. The companies can act independently of large energy suppliers and don't have to worry about rising electricity costs or power failures.
