Solar tracking systems provider DEGERenergie today announced it has combined its maximum light detection (MLD) technology with a new storage solution suitable for everyday use: a battery management system. The company debuted its market-ready solution at Intersolar Europe 2012.
The system’s prototype has been operational, without problem, since fall 2011, DEGERenergie says. The first systems will be available in September, but pre-orders are being taken now.
The system combines high-performance solar modules, DEGERenergie MLD tracking technology and a battery storage management system. DEGERenergie calls its storage solutions “Maximum Solarpower Storage,” or MSS. The company says approximately 6,000 kWh can be generated each year by combining the MLD and MSS technology, which, it says is about 45 percent more energy than fixed solar modules, regardless of the location.
The company’s tracker MLD technology enables the module surface to be precisely positioned to receive the maximum sunlight at all times, throughout the entire year. This technology is effective regardless of clouds, rain or fog. Another advantage is the balanced load profile: MLD tracking systems evenly generate electricity the entire day. Fixed systems on the other hand, peak around noon, yielding less in the morning and afternoon when normal households have consumption peaks, thereby providing less electricity than what is consumed. MLD systems, however, provide sufficient solar energy for direct consumption without the continuous need for batteries.
Additionally, batteries that serve as energy buffers can be recharged much gentler with even loads than with voltage peaks. For this reason, the system needs fewer, smaller batteries and provides a longer service life. MLD tracking technology saves around 30% battery capacity, the company says.
The fully functional end-to-end system (including installation) costs around 25,000 Euros. “Based on this, our customers can estimate their electricity price for the next 25 years on today’s level,” DEGERenergie CEO Artur Deger said.
DEGERenergie offers a “care-free” package for the duration of 25 years. “With this package, we take responsibility for the all-round maintenance of the system and make sure that it works perfectly for 25 years, including costs for spare parts,” Deger said. The innovative DEGERenergie end-to-end solution will be available in Germany starting September 2012.
