About RayGen

Utility-scale solar and long duration energy storage technology, backed by energy majors

Our Vision

Accelerate the transition to renewable energy, with RayGen as the technology provider of choice.

Founded as the lowest-cost solar technology

RayGen was founded in 2010 to develop the world’s lowest-cost, highest-efficiency solar technology. By focusing sunlight onto a small area, RayGen’s approach to solar captures almost all of the sun’s energy, as electricity (via high-efficiency solar cells) and heat (via water used to actively cool the solar cells).

Expanded into long duration energy storage

By 2019, the market needed bulk storage that could soak up low-value, excess renewable energy. Work began on integrating RayGen’s record-breaking photovoltaic technology with an electro-thermal energy storage solution that would cater to customers day and night.

Today, a leader in solar and storage

Backed by global energy majors, RayGen delivered the world’s largest next-generation long duration energy storage project – at 50MWh – in Australia, and is developing multi-GWh solar-plus-storage projects across the globe. RayGen offers proven, reliable and flexible renewable energy solutions for on-grid utilities and large industrial baseload.

Strategic Investors

RayGen is an Australian technology company backed by investment from Equinor Ventures, SLB (formerly Schlumberger), AGL Energy, Photon Energy Group, Chevron Technology Ventures and ARENA (Australian Renewable Energy Agency). Representatives from Equinor Ventures and SLB are members of RayGen’s Board of Directors.
