Vladislav Iliev Posted July 6 Share Posted July 6 Hi. In help-section explanation of the "Effect of the by-pass diodes" starts with 3 hypotesis and states: Fraction for electrical loss should always be set to 100% How would that change in case of PV modules with 3 sub-modules in portrait orientation ?

Michele Oliosi Posted July 6 Share Posted July 6 Hi sorry that page was not updated in a while. The following page will help you configure the partitions: https://www.pvsyst.com/help/shadings_partitioninstrings.htm Link to comment Share on other sites More sharing options...
Vladislav Iliev Posted July 6 Author Share Posted July 6 How panels with sub-modules should be configured (e.g. partitionwise / fraction for electrical effect,%) ? Any cases /examples when fraction for electrical effect should be set to less then 100% ? Link to comment Share on other sites More sharing options...
Michele Oliosi Posted July 6 Share Posted July 6 This is what the help page tries to answer. The examples shown on the page are all for modules with either 3 or 6 (half-cut cell modules) submodules. The fraction for electrical effect should be 100% whenever the shadings are regular (regularly arranged rows, not many shading objects). If you have irregular shadings in that case you can decrease the electrical effect fraction. Link to comment Share on other sites More sharing options...
