The Sun Simba HCPV is unlike anything else on the market

• The LSO is a completely new, highly efficient and low cost technology able to concentrate light up to 1400 suns – it’s not just another lens or mirror design.
• The Staggered Row design is what delivers our superior wind load reductions and enables passive cooling.
• The thinness of the LSO allows for the Staggered Row design.
• Our system is completely unique and less expensive than anything in the market.
• Our patented designs and technologies working together are what make the Sun Simba HCPV possible.
  

A photovoltaic system at a fraction of the cost per Watt of existing systems

• Uses significantly less materials.
• Mainly aluminum and acrylic - widely available low cost commodities.
• No need for active cooling.
• Reduced wind loading allows for lighter, less expensive tracking systems.
• Manufactured by simple automated processes.

• Uses the latest in high efficiency III-V cells.
• Capable of concentrations up to 1400 suns.
• Modules are extremely efficient, with very little dead space or optical loss.

Efficient passive thermal management

• The materials use block infrared radiation, preventing it from concentrating at the PV cell.
• The tiny loss in power from less IR reaching the cell is more than compensated for by the higher efficiency gained by a cooler cell.
• Heating does occur, however the aluminum spine is cooled by convection which allows hot air to escape up and through air gaps in the solar modules.
• Normally, introducing air gaps would mean adding dead space to the module, reducing efficiency. By making the spacing vertical, no dead space is introduced on the sun facing surface.
• The Staggered Row design allows for easy air circulation without reducing efficiency.
• PV cells are thermally bonded to the aluminum support tray – this allows heat to easily escape into the air.
• Even in critical conditions the cells easily remain well within operational limits
• Critical Conditions - 50° C ambient air temperature, 850 W/m² of direct sunlight, zero wind, zero humidity. Even in these extreme conditions, cell temperatures are maintained well within optimal operational temperatures.
  

Unique staggered row design reduces down-time due to wind and reduces tracker costs

• Wind load is much more significant than panel weight when designing trackers; high wind loads require extremely heavy duty trackers.
• By significantly reducing wind loads, lighter trackers are possible, lowering costs.
• Our wind load reductions are so significant, even with lighter trackers, our systems will have less downtime and maintenence due to high winds.
• At 70 km/h (43 mph) winds, wind load reduction models predict a 60% reduction.
  

Solid, sealed optics coupled directly to the PV prevent moisture damage and optical misalignments

• In other CPV systems, as different materials heat and expand, different expansion rates can cause optical misalignments, causing downtime, lost efficiency and potential damage to the modules.
• Our LSO optics are designed to expand and contract without causing problems, and are attached directly to the PV cell - so misalignments cannot happen.
• PV cells are encapsulated within the module to prevent moisture damage.
• In other CPV products, air spaces in the bulky structures trap air that expands as it heats – solving this problem requires expensive valve systems.
• By not needing a container and eliminating air spaces, we sidestep these issues and eliminate the costs involved.

Modules are fully recyclable, made of non-toxic materials

Note, the panels pictured here are NOT Sun Simba HCPV panels, but are conventional silicon PV panels mounted on trackers. The picture is used with permission, and demonstrates the concept of dual land use with tracking systems.

• Modules are made from aluminum, acrylic, glass, copper wiring and multi-junction cells – all of these are recyclable with high recovery values at the end of the 25 year module life span.
• The modules are non-toxic, the materials not react with water and will not cause site contamination.
• The use of sun tracking systems allows for dual use of the land (as in the image above) and minimizes site impact.
• 10 Megawatts of Sun Simba HCPV modues (the equivalent of a small solar farm) will offset up to 3470 tonnes of carbon dioxide a year (based on the Ontario Electricity Emission Factor).
