PAVANAELPULA Posted March 26, 2019 Share Posted March 26, 2019 Hi PVsyst,We found new option of "Irradiance optimization" in PVsyst 6.7.9 version. However, we didn't found any reference or guidance on how it work ?? and it background methodology ??.when are not sure when to use this option ??.Request to provide some details on newly available option "Irradiance optimization" in Project design>Orientation Tab.Regards,Pavan Link to comment Share on other sites More sharing options...
dtarin Posted March 28, 2019 Share Posted March 28, 2019 (edited) I am also interested in knowing more about this and where it originated from, how it works, etc. Edited April 2, 2019 by dtarin Link to comment Share on other sites More sharing options...
MNWild Posted March 30, 2019 Share Posted March 30, 2019 +1 For an explanation.Or a warning not to check the new box that gives more energy for free. At least a single sentence, slightly vague, release note to tease us but leave us with more questions, only joking. Best wishes to allp.s. Request to also include a nice short video with each software release note to illustrate, visually, confirming what's been changed/why and how to use..and more importantly what old forum/help file information is entirely obsolete.

TerraWatt Posted April 10, 2019 Share Posted April 10, 2019 Would be nice if an explanation is released with the release notes... Link to comment Share on other sites More sharing options...
André Mermoud Posted April 17, 2019 Share Posted April 17, 2019 The usual tracking strategy defines the tracker's angle in order to minimize the incidence angle for a given sun's position. This new strategy determines the orientation according to the best irradiance received by the trackers. This may be different than the previous strategy as the transpositon of the diffuse component is proportional to (1 + cos(i) / 2), where i = incidence angle. Therefore the higher tilt, the less transposed irradiance. For a fully covered weather, the optimal tracker's position will be horizontal (Phi = 0)In practice on real systems, this strategy may be easily applied by putting 2 irradiance sensors on the tracker, separated by a black wall perpendicular to the tracker: the best orientation is obtained when the measured irradiances are equal.

david.zar Posted July 2, 2019 Share Posted July 2, 2019 Hi, Is it possible to use "Backtracking" and "Irradiance Optimization" in the same simulation? Link to comment Share on other sites More sharing options...
