February 16, 20206 yr comment_3464 Hi, I would expect the orientation to be "the same" on the south and the north side of a roof I am making calculations on. Using a "east-west" system divided on south and north side of the same roof, in this example i get following orientation. North Building: 50% are 115° South-east + 50% at 307° North-west South Building: 50% are 127° South-east + 50% at 295° North-west I would expect the orientation to be either 115°/295° or 127°/307° and not the mix of 115°/307° and 127°/295° that have been used in this simulation. Why is this? Best regards Daniel Report
February 17, 20206 yr comment_3466 Hi Daniel, could you provide a project file or a screenshot of your PV system? This would be very helpful in order to analyse the problem. Thank you and kind regards, Martin Report
February 17, 20206 yr Author comment_3471 Hi, yess ofcourse, We have planned for panels on both sides of the ridge, expecting more consistent orientation. On the south side of the ridge i get this, And on the north side, this Roof illustration Best Regards Daniel Report
February 17, 20206 yr comment_3473 Hi Daniel, it looks like your roof has a ridge that is not exactly in North-South direction, is that correct? In that case, if you have a small inclination of the roof surface and you mount a PV system with its own orientation and tilt, the resulting orientation and tilt (or inclination) will be different. For that reason there is also a small dialog in the mounting system dialog that explains this a bit: Click on Orientation -> Calculate Hope that helps, kind regards, Martin Report
