BSQ Solar Triptic

BSQ’s High Concentration Photovoltaic System (CPV) is the perfect warhorse for the new generation of Beyond-Shockley-Queisser record-efficiency photovoltaic cells.

With more than a decade of intensive field testing and thorough development in the lab, the BSQ solar CPV system combines high efficiency, high concentration, non-imaging optics, with a simple and rugged module design especially devised for local assembly, and a truly robust and highly accurate sun tracker. Everything is optimized to provide the most cost-effective path, for the industrialization of competitive CPV electricity generation systems.

  • Very high concentration ratio of 820X and possibility to scale up to 1000X

  • Unique dome-shaped concentrating Fresnel lens with top dimple, produced by automobile headlamp manufacturer maximizes acceptance angle pointing tolerance up to 1°

  • Secondary optical stage based on kaleidoscopic optics, that through total internal reflection creates uniform light flux over the cell, preventing conversion losses due to chromatic aberration or inhomogeneous intensity distribution

  • Overall optical efficiency over 85% enables high overall conversion efficiency

  • Integration of high efficiency triple junction cells with 37% average efficiency by 1st tier manufacturer

  • Kaleidoscopic homogenizer and three junction cell, both packaged in fail-proof receiver block

  • Over 30 yrs lifetime for encapsulation polymers in receiver block when subject to accelerated aging under most critical conditions: concentrated UV radiation in damp heat environment

  • Only requires passive cooling, with cell directly laminated in receiver block onto aluminum substrate, with no need for fin heat sink

  • CPV systems specially designed for affordable local assembly closer to the market, thus reducing shipping costs
  • 280W per CPV module (@ STC: 1000W/m2 @ 25ºC cell temperature) with 28% conversion efficiency
  • Sustained high energy output especially at high temperatures
  • Light CPV Modules: Monocoque structure made of aluminum of approximately 0.1kg/W
  • High resistance CPV module structure: up to 5400Pa in the aperture plane
  • The special dome-shaped lens enables self-cleaning: just 1mm of rainfall
  • Two axis pedestal tracker designed for optical quality stiffness: maximum 0.3° flexure under maximum service conditions
  • Numerically optimized aperture surface for least structural weight and cost
  • Auto-calibrated open loop sun tracking controller achieves 0.1° minimum tracking accuracy
  • Extended sun tracking range to harvest maximum energy
  • Best CPV module and tracker technologies resulting from more than 10 yrs. of sustained development and testing, including extensive field testing
  • CPV Modules are pre-assembled and pre-leveled in the factory and shipped as packs of <<Super Modules>> ready for quick installation in the field on top of the tracker frame.
  • Specially designed CPV supermodule packs for carrying in standard truck trailers and maritime containers and handled by regular cranes
  • The CPV system (tracker + modules) arrives in the field in four separate and pre-mounted sets, to reduce installation steps and crane time in field
  • Costly leveling in field reduces to just simple leveling of the four CPV Super Modules in each tracker
  • CPV sun tracker accuracy calibration is automatically carried out during installation, and thereafter operates on an open-loop basis with no dependence on faulty and maintenance prone tracking sensors
  • CPV tracking controllers are LAN networked and internet connected enabling remote operation and control, and failure diagnosis through historic log analysis
  • Landscape tracking aperture profile designed to reduce shading losses
  • Reduced surface environmental impact. No permanent shadowing allows dual-use of land
  • Pedestal CPV trackers used, with single point foundations, allow for less land preparation and installation in undulating terrain
  • Communications based on MODBUS protocol enable simple integration of standard industrial sensors and SCADA systems
  • Simple to monitor: One cable can wire up to 32 systems in the field. Allowable distances of 1000m per group
