Thread-topic: Type 194 Efficiency problem

Hello TRNSYS user,

I am analyzing the efficiency of photo-voltaic panel (type 194) for entire year. It goes to zero after each month which should not be the case. ( check the attached file for results)

Equation used for efficiency .... "(eta_system= (E_electric/max(1,E_solar)) )"

did anyone else had same issue... Any help will be greatly appreciate thanks!

Thanks,

Sandeep Chahal
