jackattack Posted May 5, 2014 Share Posted May 5, 2014 Hello,When modeling trackers I often want to be able to adjust the slope of the tracker to reflect a north or south-facing slope by adjusting the Axis Tilt in the Near Shadings module. However I have noticed when creating models and then running simulations, that the software does not distinguish between a "flat" array (zero degree axis tilt) and a +1 or -1 degree axis tilt - meaning the production is the same for all three of these scenarios, although in the real world we know production would be different, even by a little bit. Production only changes when you hit +/-2 degrees axis tilt. We have been asked by many clients to model systems with less than 2 degrees tilt, because they want to see how those slopes will affect production. It would be good to be able to do this in Near Shadings with precision. You can do this in the Orientation module (if you are not using Near Shadings), however it is my understanding that using Near Shadings is always going to be more accurate than just Orientation.Please let me know if this is something you can change or if I'm missing a hidden parameter that could change this. Also, in the US we tend to use percentages to measure slopes rather than degrees - if it's possible to make that unit change in future versions, that would be great! Currently the civil engineer gives me a slope in percentage and I have to convert it to degrees for PVsyst.Thanks. Link to comment Share on other sites More sharing options...
