CPV Dish

The SST Concentrating PV (CPV) solar module system is a modular liquid-cooled CPV design that is integrated with the optics of the SST solar dish. In some cases the CPV module could also be used with tower/heliostat collectors. 12 CPV modules are packaged into the Receiver that is used with the SST dish. As this technology is still in development, the initial target rating is 10 kW for pre-production dish units, with 15 kW as the commercial target rating.

Unlike the more common CPV designs that use lenses, the SST CPV design is based on a nominal 1 kW “dense array” building block CPV module. The CPV module uses water cooling, circulated in a closed loop to a radiator like a car engine cooling system, and so it is dry-air cooled and does not consume water. This liquid cooling method provides better thermal management of CPV solar cells operating under very high concentration – over 1000 suns – and for better solar production in high temperature and harsh desert regions.

What is the cost energy value of a SST CPV dish?

CPV MODULES FOR ELECTRIC POWER

Currently SST is able to make prototype and demonstration systems in preparation for commercial manufacturing partnerships. Target cost for this Dish-CPV product is under $2/W in high-volume manufacturing, using CPV “multi-junction” PV cell technology that is on a pathway for increasingly high efficiency. Expected CPV cell improvements over time will increase the module rating from initially 1 kW (including all system losses), to about 1.7 kW per module. These efficiency gains help to reduce the effective cost of the collector system. Two-axis tracking is used which provides for about 20-30% higher energy output than a fixed-PV system of the same rating, assuming sunny conditions, and higher annual output than solar trough or tower systems.
