Giovanni, It has been some years since I worked with Type30 but if my recollection serves me, the configuration that you describe is not one that Type30 can handle. I wrote a component that is able to handle that case. It is Type551 (PV Array Shading) in the TESS Green Building Library. If you do not have the library, I would be happy to send you the documentation for that component so that you can determine whether it will suit your needs. Kind regards, David giovanni nurzia wrote: Dear David, -- *********************************************************************** Thermal Energy System Specialists (TESS), LLC David BRADLEY 22 N.
