Solar modules are fixed to ropes (upper edge of the module) and thin-walled pipes (lower edge of the module, Rope-in-Pipe system).
To optimize the sunlight transparency, rainfall homogeneity, snow load and wind resistance we suggest the use of:
- cylindrical solar panels and/or/combined with
- narrow plane panels rotatable around a longitudinal axis.
Narrow rotatable modules optimize the Solar Sharing in two ways:
- solar tracking with falling of sun's rays perpendicular to the panels
- full solar output outside the crop growing season, no snow in winter
Sunlight transparency - width of narrow panels (20-40 cm) vs. size of standard panels (100 x 165-200 cm)
Rainfall homogeneity - can be maximized by the longitudinal rotation to a vertical position of panels
Snow load - low adherence of the snow on cylindrical panels and narrow panels in the vertical position
Wind resistance - the in-panels with low wind resistance enabled to reduce the cost of used steel.
Through the longitudinal rotation of panels, seasonal solar sharing can be optimized.
