The standard H1 heliostat ships with a 1.21M x 1.21M (48″ square) aluminum composite reflector.
- The 48″ square mirror reflects over 1000 watts onto a target in optimal conditions, or over 115,000 lumens if used for lighting applications. This is the most energy/light captured by a commercially available heliostat.
In contrast to the H1, some smaller / consumer-oriented heliostats offer a mirror only .5 square meters in area, reflecting @ 425 watts of energy. It would take 4 or 5 of these small units to equal one H1 heliostat.
