RayGen’s PV Ultra heralds the future of solar power, utilising the entire sunlight spectrum with world-record electrical efficiency, least cost mirror collectors and high value by-product heat.

RayGen’s PV Ultra technology delivers low cost solar electricity and heat (full turnkey cost of less than US$0.75/Wco-gen). The dispatchable heat addresses a white space in the renewable energy market – industrial thermal solar energy supplied at a lower cost than natural gas. In areas where there is no local heat requirement, the heat can be transformed into low cost freshwater production (using multi-effect distillation), district chilling (using absorption chillers) and electricity storage (using a solution developed internally).


The Australian manufactured product has been designed to produce more revenue products for the same installed capacity with upgrade flexibility for a longer lifetime.

RayGen Resources Pty Ltd comprises a team of 30 employees across engineering, manufacturing and sales, cumulative deployment of approx. 3MW (1MW of electricity and 2MW of thermal heat), a production capacity for 75MW p.a. and a World Record for Solar System Efficiency with UNSW. RayGen has received ongoing investment and support from many private and public investors, including A$4.8m from the Australian Renewable Energy Agency (ARENA) and A$2m from the Victorian New Energy Jobs Fund in 2017.
