The 15kW hybrid solar system with 15,36 kWh storage offers a professional solution for high energy demands. With 36 high-performance bifacial solar modules, you can generate between 13.500 and 16.000 kWh per year, depending on location and orientation – ideal for large households, apartment buildings, or small businesses. Generous storage capacity for maximum independence The high-performance 15,36 kWh battery storage system stores your solar power for the evening and night hours. This generous capacity allows you to cover a large portion of your electricity needs yourself, even during periods of higher consumption, and minimize your reliance on grid power. The storage system is modular and can be expanded to up to 20,48 kWh if required. Emergency power supply for critical consumers In the event of a power outage, the system automatically switches to emergency power and supplies a separate circuit with energy from the battery storage. You decide which devices are important to you and should continue to be powered during a power outage. Bifacial technology for higher yields The JA Solar JAM54D40-LB modules utilize bifacial technology and generate electricity from their backsides as well. Reflected light from bright roof surfaces or snow can increase yields by up to 30%. With an efficiency of 22,3%, these modules are among the most efficient on the market. Professional hybrid system from Sofar The Sofar HYD 15KTL-3PH hybrid inverter intelligently connects solar panels, storage, and the grid. With two MPP trackers, it optimizes energy yield even with two differently oriented roof surfaces or partial shading. The system can be conveniently monitored and controlled via a Wi-Fi logger – anytime, anywhere, using an app. Perfectly coordinated complete system With a 25-year product warranty on the modules and a 10-year warranty on the inverter, you are investing in a secure, long-term energy supply. The Sofar BTS battery storage system is specifically designed for the Sofar HYD inverter series and guarantees optimal interaction of all components. The system requires approximately 70 m² of roof space. Installation note This system must be connected to the power grid exclusively by a qualified electrician registered with the grid operator. Registration with the grid operator and in the market master data register are required. We can put you in touch with an installation company upon request.

The 15kW system with 15,36 kWh storage is suitable for large households of 5 or more people with an annual consumption of 7.000 to 10.000 kWh. It is also ideal for apartment buildings or small businesses with high energy demands during and outside of business hours. How big does my roof need to be? You will need approximately 70 m² of free roof space for the 36 solar panels. Ideally, the panels should face south, southwest, or southeast. East-west facing roofs are also possible, but will result in lower yields. Flat roofs with appropriate mounting systems are also suitable for commercial buildings. How does the emergency power function work? The Sofar hybrid inverter features an emergency power function. In the event of a power outage, the system automatically switches to island mode and supplies a separate emergency power circuit with energy from the battery storage. This emergency power circuit must be configured separately during installation and can, for example, protect critical equipment or entire areas. Is the system suitable for commercial enterprises? Yes, this system is ideal for small businesses, workshops, or offices with high electricity consumption. It is particularly advantageous for businesses with consumption outside of peak hours, as the large storage unit stores excess solar power. However, please be aware of the tax regulations specific to businesses. Can I expand the storage later? Yes, the Sofar BTS system is modular. You can add one more BTS 5K module and increase the storage capacity to 20,48 kWh. This expansion must be carried out by a qualified electrician and reported to the grid operator. Who is authorized to install the system? Connection to the power grid must be carried out exclusively by a qualified electrician registered with the grid operator. The installation of the modules on the roof should be performed by a specialist company (e.g., roofer or solar installer). For a system of this size, we recommend hiring experienced specialists. What registrations are required? The system must be registered with the local grid operator before commissioning. Registration in the market master data register of the Federal Network Agency is also legally required. Your qualified electrician can assist you with this. What annual return can I expect? With optimal south-facing orientation and a 30° roof pitch, you can expect an annual yield of 13.500 to 16.000 kWh in Germany. The actual yield depends on your location, roof orientation, pitch, and any shading.
