April 2020: RayGen and Azur Space announce Strategic Alliance for high-efficiency solar cells in breakthrough 'solar hydro' technology

AZUR SPACE Solar Power GmbH (Azur Space) and RayGen Resources Pty Ltd (RayGen) recently formalised a strategic alliance that will include joint R&D and supply of Azur Space’s high-quality photovoltaic components for large scale deployment of RayGen’s PV Ultra system.

The first project under this alliance will be a fully dispatchable renewable energy facility delivering 4MW of solar generation and 3MW/50MWh (17 hours) of storage. RayGen is partnering with major Australian power utility AGL on the feasibility stage of the project. RayGen recently secured $3 million AUD funding from the Australian Renewable Energy Agency (ARENA) to advance the project to financial close in 2020. The project will be located in Carwarp, Australia. 

Azur Space has more than 50 years’ experience in solar cell technology, primarily in high-efficiency multi-junction photovoltaics. In its partnership with RayGen, Azur Space brings its latest photovoltaic technology, developed for use in satellite systems, back to earth for this commercial terrestrial application. RayGen has developed a solar-plus-storage system (‘solar hydro’) that supplies on-demand, day-night solar power and supports grid reliability.

Azur Space’s CPV solar cells are integrated into the small, high-tech heart of RayGen’s system, the PV Ultra module.


● Cell efficiency approaching 40% (sunlight to electricity)

● 750x average solar concentration

● High module power density, 750kW per m2 (250kWelec plus 500kWheat)

● 4 m2 of solar cells per MW of electricity

Azur Space Managing Director Jürgen Heizmann said: “Azur Space is excited to be working closely with RayGen to commercialise their world leading solar technology. We have known and worked with RayGen for ten years and believe that they are world leaders in the field.

We will provide technical support and our high-performance components into RayGen’s innovative, low cost clean power systems.”

RayGen CEO Richard Payne said: “We are pleased to announce our strategic alliance with Azur Space. Azur Space has world-leading capability in high-efficiency, long-life multi-junction solar cells.

The extraordinary power density of RayGen’s modules with Azur Space’s CPV cells underpin a new economic model for manufacturing and deploying solar power systems worldwide.”


RayGen Resources is an Australian technology company with world-leading capability in the next generation of solar power and electricity storage. RayGen’s “Solar Power Plant” (‘solar hydro’) consists of RayGen’s proprietary PV Ultra (solar co-generation) and Thermal Hydro (electro-thermal storage) technologies. These technologies are designed in Melbourne and are protected by six patent families. RayGen has an experienced team of 30 staff in Melbourne and Bendigo, working across engineering, manufacturing, operations and commercial functions. In 2015, its first PV Ultra project started supplying power to farms near Bendigo in Victoria and has now been operating with high performance for five years. RayGen has built and sold 1MWAC (3MWco-generation) PV Ultra projects supported by power purchase agreements. RayGen develops and manufactures its high-efficiency solar modules at its 25MWAC manufacturing facility in Melbourne. For more information, please visit
