PV UltraClass-leading asset utilisation and material efficiencyPV Ultra costs less than USD 0.75/W,
turnkey. This low price is enabled
by the highest asset utilisation
and highest commercial efficiency
(sunlight to AC electricity; and sunlight
to energy) of any solar solution
on the market.

Concentrated value unlocks long, versatile asset lifePV Ultra modules are just 0.1% of solar area (99.9% standard mirrors), enabling the PV Ultra system to be:
» Very easy to upgrade (avoiding technology lock).
» Very easy to reconfigure to different commodity mix (resilient asset value in event of market shock).

PV Ultra installation is low in complexityTracking mirrors (heliostats) are self-powered and autonomous, and PV Ultra uses same mast as mobile phone tower.
» Pile-driven heliostats require no concrete foundation nor electrical wiring
» Versatile solar field can be deployed in rocky or flood-prone geography (dual use grazing encouraged)
» Closed-loop tracking software eliminates regular in-field alignment with technician
» Tower and other central infrastructure arrive on-site pre-commissioned and skid-mounted

PV ULTRA
Dispatchable Cooling w/ Absorption Chillers:An absorption refrigerator is a type of chiller thatuses a heat source to provide the energy needed todrive the cooling process. Major globalmanufacturers of absorption chillers includeThermax, JCI Hitachi, Kawasaki and Panasonic.
Desalinated Freshwater w/ Multi-Effect Distillation:Multiple-effect distillation (MED) is used for seawater desalination and consists of multiple stages or"effects". Each stage essentially reuses the energyfrom the evaporated water in the previous stage,with successively lower temperatures and pressures.
Electricity Storage w/ Storage UltraTM:‘Storage Ultra’ is a proprietary configuration ofmature industrial equipment (patent pending). Thethermo-electric storage leverages PV Ultra’s heat toboost the overall round-trip electrical efficiency.
