Do LightManufacturing Heliostats Require a Computer for Tracking?

No.  The H1 heliostat has an internal microprocessor, and no external computer is needed for regular heliostat operation.  A computer or smart-phone browser IS used for initial setup – eg entering heliostat location (lat/long) time of day, time zone, etc – and for defining the heliostat ‘targets’ – where you want the light and heat from the heliostat to go.   After this initial setup, which is done wirelessly, the heliostat operates totally autonomously.  All it needs is 12V DC power – which can be provided by our optional P1 or P2 solar power supplies if you’re installing the heliostat somewhere without available local power. Autonomous heliostat operation is very important if you’re managing multiple units – you don’t want your entire heliostat array taken offline because of a central computer failure, or because of a wiring problem.  LightManufacturing H1 heliostats are robust and failure-resistant in part because each one operates autonomously.   This is important both for heliostat architectural / green building applications and for heliostat solar thermal manufacturing.
