Identification

Stellio Heliostat delivers a solution to deploy high-efficiency solar power generation in sunny areas with large-scale, grid-connected facilities thanks to its combination of high optical quality at low costs.

Renewable energy sources must replace fossil fuels. Stellio believes that solar energy is the single most important renewable energy source but there are challenges to overcome such as electricity cost and generation intermittency. Both of these are tackled by Stellio Heliostat, providing low cost dispatchable solar electricity using solar-thermal power tower plants with large integrated thermal energy storage and Stellio Heliostat fields. Stellio's key technical data including an optimized reflective area of 48.5 m², high tracking accuracy (better than 0.6 mrad @ 4 m/s) and high optical quality (sigmaxy below 1.6 mrad). Overall, Stellio Heliostat appropriate size and precise optics at low manufacturing costs result in a significantly improved cost/performance ratio, and thus in lower electricity generation costs.
