A low cost but high efficient drive system is chosen which reduces energy consumption to a minimum amount and leads to low cost for PV cell and energy storage. The usual boundary layer wind tunnels tests for heliostats are proven regarding energy spectra to avoid oversizing of steel structure and drives or failures because of underestimations of the loads. The concepts for wireless control and energy supply, the wind tunnel investigations and the first rim drive heliostat prototype are presented.enhttps://creativecommons.org/licenses/by/4.0/central receiverautonomous heliostatrim drivewind loadsIngenieurwissenschaftenConference Paperurn:nbn:de:gbv:830-882.04998510.15480/882.241410.1016/j.egypro.2015.03.02110.15480/882.2414
