Solar storage system

A solar storage system is the ideal solution to allow solar energy produced during the day to be used in the home at night or on cloudy days.

This is one of our areas of speciality, and we are able to offer the full range of solar storage system services, from consulting and planning through to installation and maintenance.

In spite of the power that is generated by a solar power system, building owners have until now been dependent on electricity from local energy suppliers, especially at night. An additional “sun battery” affords greater independence, since surplus power produced during the day can be stored locally instead of being delivered to the power grid. To ensure maximum benefit, the solar storage system is equipped with an intelligent system that regulates electricity use in the building around the clock. The “sun battery”, which is around the size of a refrigerator, is generally installed in the basement and then connected to the solar power system on the roof of the building. Existing systems can be retrofitted, and new systems will be fitted with the “sun battery” upon installation, or will at least be configured to allow expansion at a later date.

Thanks to our comprehensive experience, we are able to offer professional services in the area of solar storage systems – everything from a single source, whether you wish to expand an existing system or install a completely new one. 


Consulting and planning

We provide support right from the start for interested parties setting up their own solar storage systems. On the first site visit, a specially trained solar systems planner will draft specific proposals and ideas. We will also indicate which subsidies will be available, if applicable.

Using the findings obtained on site, we will determine the best-suited battery systems and will devise individual arrangements taking into account local conditions. By taking into account computer-based analyses and the building elements selected, the optimum control system for the components in a completely new system can be determined. This means we are able to draw up a personalised offer for a solar storage system that is both economical and environmentally friendly.

Where applicable, the planning application, the application to connect to the power grid and the application to the funding programme will be managed by us. This guarantees fast processing of the administrative aspects. 


Project management and installation

A project plan will be created and scheduled together with the customer. Our project managers will then use this plan as a guide to ensure the timely completion of the work.

In just a few working days, our experienced assembly team will install your solar storage system. Our experience, modern tools and professional working practices mean we can guarantee the smooth operation of your solar storage system for 12 to 20 years. 


Service and maintenance

Although solar storage systems are very low-maintenance, especially the lithium iron phosphate batteries used by us, it is still worth carrying out regular upkeep. This helps to maintain efficiency and will ensure an operational life of between 12 and 20 years. We are happy to take care of these steps for our customers.
