We build solar heliostats that are guided by dual axis optical solar tracking electronics. The analog solar tracking circuit controls two mechanical actuators that move a mirror plane in
two axes. The mirror plane will reflect the sun to a stationary target during the day and then return to a preset morning position after sunset. The tracking electronics are capable of tracking the
sun with sub degree accuracy.
This heliostat has nine 30 Cm sq programmable mirrors delivering 9X concentrated solar power (CSP) to a fixed target. The sun delivers approximately 1000 watts/m2 so a one sq-Cm mirror can be
expected to redirect around 80 watts of power after reflective losses.
This heliostat can direct around 700 watts of CSP to a 1 square Cm target. This energy can be used for heating, lighting and electric generation.
