How to solve this error while using PV Array in my simulink model ??

An error occurred while running the simulation and the simulation was terminated

Caused by:

Algebraic state in algebraic loop containing 'Project_Third_Sem/PV Array1/I Filter/First-Order Filter/Model/Sum1' computed at time 0.035647761949266853 is Inf or NaN. There may be a singularity in the solution. If the model is correct, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)
