Hi,


I am doing a project to model a grid connected pv system using simulink.
I need to model an array with 18 parallel x 21 series module, where each module has 36 solar cells in series.
I use the solar cell block in SimElectronics. but it only works for a single solar cell.
I used to connect the solar cells together, it still works for a module.. but not for the array and the simulation time is super long.

Then i tried to adjust the parameters to make it represents as an array, but error occur on the solver block. It said.."Nonlinear solver: failed to converge, residual norm too large. Initial conditions solve failed to converge."..... maybe i need to adjust at the solver configuration block but i dont know what to adjust..
anyone has any idea?

thanks..
