Dear Sir I have performed the simulation of a grid connected PV plant that consist on 6 sub-arrays. Each sub-array has the same inverters, shading scene, numbers of modules and strings and detailed losses, .. Version A is formed by 1 array with 370 Wp modules and 5 arrays with 365 modules. Version B is formed by 2 arrays with 370 modules and 4 arrays with 365 modules. When carrying out the simulation, option B should give production and PR higher than variant A because that configuration has more peak power but it is just the opposite. I have check module performance at .pan files and the values are ok. I work with 6.75 PVsyst version. Could you give me an explanation? Thanks

Good morning Sir, I have obtained strange results when performing a simulation of a grid connected PV plant. The plant has 6 sub-arrays with the same inverter, the same scene (number and type of tracker) and the same array design. One of the variants includes 5 sub-arrays with Risen modules RSM72-6-365M (PERC) each + 1 sub-array with Risen RSM72-6-370M (PERC). Another variant has 4 sub-arrays with Risen modules RSM72-6-365M (PERC)+ 2 sub-arrays with RSM72-6-370M (PERC). The second variant has higher arrays global power, which should give higher production and PR, however the results are opposite to those expected. The detailed loss parameters are the same in both variants. The .pan files used in the simulation are those provided by the manufacturer Could you inform me why these results are obtained? Thanks Manuel
