Abstract

In the paper, a planar 2 DOF RSSR solar tracking linkage applicable for all latitudes is analyzed. The mechanism is contained in the vertical North-South plane of the observer. The coupler angle relative to horizontal plane defines the tilt angle χ of the active conversion surface and depends on the latitude and Earth’s declination. It can be modified by a linear actuator. The coupler passive motion defines the diurnal angle φ3 of the active conversion surface and it is driven by a second linear actuator. The angles χ and φ3 are limited to - 65° … + 65° by constructive requirements of the linkage and pressure angle. Optimal mechanism design and functionality simulation at different latitudes are detailed in the paper. A case study for latitude φ = 50° corresponding to Krakow region is presented in the paper. As result, tracking efficiency is very high, the solar energy lost is below 1% for winter time and under 4% for summer time from the total available solar energy in a clear sky day.
