ErSol to Supply Solar PV Cells to SV Solar

ErSol Solar Energy AG of Germany will provide high efficiency c-Si cells to support the development and early production stages of SV Solar’s Sol-X2 internal flat-plate concentrator solar photovoltaic (PV) modules.

ErSol will be supplying E6M+ Black Power Cells using monocrystalline silicon to achieve between 16.26% and 17.47% efficiency. Initially ErSol will be supporting development and preproduction. After SV Solar satisfies certain milestones, ErSol will be providing a sufficient quantity of cells to support SV Solar’s initial mass production ramp by which time a long-term cell supply contract will be established. “The key benefit of Sol-X technology is the fact that we can generate the same or even more power with less than half the number of PV solar cells,” said Dr. Christoph Goeltner, VP of engineering for SV Solar. “Since Sol-X is essentially a ‘multiplier’ of the solar cell used, ErSol’s high efficiency E6M+ cells provide a real advantage to achieve high module efficiency.” SV Solar’s Sol-X2 products are high efficiency, low cost flat plate modules using a unique “internal” concentrator. Sol-X2 modules require less than half the number of solar cells when compared to traditional solar modules, while producing equivalent or even higher power output. Solar cells currently account for up to 75% of the total module cost, and with the current shortage of refined silicon, are a limiting factor on the total production of solar modules. Since Sol-X2 utilizes a proprietary internal concentrator, the modules are dimensionally equivalent to standard flat plate modules and don’t require a complex tracking mechanism. The “compatible” form-factor of these modules enables traditional installation, and the lack of moving parts provides the long-term reliability the solar industry demands. “Given the strength of worldwide demand for solar modules, ErSol welcomes the opportunity to support SV Solar and their unique Sol-X technology,” said Dr. Claus Beneking, CEO of ErSol. “We believe this is an intelligent approach to leveraging the existing supply of silicon to meet demand in a cost effective way.”
