How it works
1. Focus Sunlight
A field of smart, self aligning mirrors concentrate sunlight onto a tower-mounted receiver containing an array of PV Ultra modules.
2. Convert To Electricity and Heat
RayGen’s PV Ultra modules convert sunlight to power with nearly 90% efficiency (one-third to electricity and two-thirds to heat) using high efficiency, actively cooled photovoltaics.
3. Capture Energy in Thermal Stores
Heat extracted from PV Ultra modules is stored as hot water in a thermally insulated reservoir, while electricity from PV Ultra or the grid is used to run a chiller to produce near freezing water in a second reservoir.
4. Generate Electricity On Demand
Stored hot and cold water drive an Organic Rankine Cycle engine (used for heat to power in the geothermal industry) to produce stable electricity on demand.
