It specifies the ratio between distance between the equivalent trackers legs (axis) and pv collector width. It has an effect for GeometryTwoAxisAstronomical tracker and GeometryOneAxisHorizontalEW tracker. For fixed mounting this parameter is used to calculate the impact of self shading. DEPRECATED use TopologyRow instead The parameter, has effect only if back-tracking is true in the case of tracking systems. It specifies the ratio between distance between the equivalent trackers legs (axis) and pv collector width. It has an effect for GeometryTwoAxisAstronomical, GeometryOneAxisVertical, GeometryOneAxisHorizontalNS and GeometryOneAxisInclined. Shading angle is the lowest sun elevation angle above the horizon plane which doesn't cause mutual shading between rows of PV modules [m] [m] Optimization category into which field topology of PV system belongs, qualitative and empirical ranking applicable for a-Si, CdTe and CIS (thin film technologies), the loss of generated electricity is proportional to the size of module area in shade applicable for c-Si, modules are landscape oriented with proper layout optimization applicable for c-Si, modules are landscape oriented with intermediate layout optimization applicable for c-Si, modules are portrait oriented with poor layout optimization, bottom cells in shade will shut the whole row of modules down PV system mounting abstract type False value for the backTracking attribute corresponds to a single tracker without neighbours (best possible option). rotationLimitEast/rotationLimitWest are the parameters pair of limiting rotation angles for 1xV, 2x and 1xNS horizontal or 1xNS inclined trackers. If tracker is purely theoretical (no limits) the value of [-180,180] should be used. tiltLimitMin/tiltLimitMax parameters are the pair of limiting tilt angles for 2x trackers. Because of technical realisations of variable tilt often alinear actuator is used, inclination angle seldom varies from (0 to 90) but often has smaller range eg.(10 to 80). If tracker is purely theoretical (no limits) the range -90 to 90 should be used. Selecting tilt limits of [45,45] will convert 2x tracker to 1x vertical with 45 degrees tilt Inclined surface tilt; 0 horizontal, 90 vertical Inclined surface orientation; 0 for North, 180 for South, clockwise It is an integer value in degrees. The value of geogr. azimuth (compass value, from 0 to 360 exclusive), at which the southern end of the axis is oriented. Regardless of the Earth's hemisphere. The value is limited to the range from 135 deg. to 225 deg. inclusive, so the deviation from the North-South line is never bigger than 45 degrees. See the documentation of the GeometryOneAxisInclinedNS tracker type. Geographical azimuth (compass) of the southern end of the tracker axis.
