Solergy Italia Srl achieves 50% thermal performance improvement with new Concentrating Photovoltaic (CPV) receiver
Novel technology, developed within the EU’s Horizon 2020 Cogem CPVTM project, exceeds performance target by 4x and helps make CPV cost competitive
Formello (RM), Italy – Solergy Italia Srl, a wholly-owned R&D subsidiary of Solergy, Inc., announced today that its new CPV receiver technology, developed within the Horizon 2020 program, reduces the operating cell temperature by 50% compared to previous designs. The lower operating temperature helps improve overall module efficiency by 12%, far exceeding the original project goal of 3%.
As temperature goes up, solar cell conversion efficiency goes down. That is why solar panels often exhibit their worst performance during the sunniest, hottest months of the year. In CPV, where the sunlight gets concentrated by a factor of anywhere from 500 – 1500x, the challenge of keeping solar cells as cool as possible is much greater.
Solergy’s new, patent-pending design relies on a closed-loop, fluid-based cooling circuit that efficiently removes heat from the cells. By controlling the flow rate, the system can guarantee steady cell operating temperature under any ambient condition. This becomes especially critical in the hot desert environments where CPV is supposed to perform best. Passively cooled systems are highly dependent on airflow for cooling. Therefore, the cell operating temperature and performance of these systems can fluctuate dramatically over the course of the day and year.
The new design also reduces manufacturing cost by reducing the number of components and simplifying the assembly process. The double benefit of higher performance and lower fabrication cost will help the CogemCPVTM project achieve its other goal of reducing overall energy generation costs by 25%.
“This latest result is an important milestone on Solergy’s roadmap to providing the lowest cost solar energy and enabling CPV to achieve its full potential,” said Professor Giovanni Lanzara, Solergy Chairman and head of the Cogem CPVTM projet.
The new receiver technology is undergoing further testing and qualification and will be fully integrated into Solergy’s CPV systems during the second half of 2017.
Solergy (www.solergyinc.com) developes, manufactures, and distributes highly efficient and reliable solar energy systems that generate the most energy at the lowest cost. It has developed the world’s first upgradeable, 40+ year lifetime High Concentrating Photovoltaic (HCPV) System that can generate electricity at a cost as low as $0.01/kWhr. The performance and reliability of Solergy’s technology have been validated by reputable 3rd parties.
