How Calculate Sizing Factor From Climate Data And Module Inclination Works?

Recommended Posts

Dear fellow PVSol users,

 

I want to understand how this sizing factor is calculated to argue why I'm choosing a given Inverter in a project. This project will be in Calama in the north of Chile and it shows me this (it's attached).

 

This are quite different parameters from the default parameters and I don't get why.

 

I would be very grateful for any help you are able to provide.

Hello,

 

For the calculation of the sizing factor from the climate data we are using an empirical approach. Here, a value is determined using the maximum radiation on the module surface. This is the upper limit of the design area (green). Subsequently, the lower limit of the design area is defined as subtracting 40% from the upper limit. This area is then again extended by +/- 20%, the tolerance range (yellow).

 

Best regards

Hello support team and thanks for your quick answer as always.

 

I understood how the range of the values its set, but I'm still not sure of this empirical approach that you mention, because in my case the inverter should be bigger than the array according to this criteria, nevertheless this paper says otherwise, actually its says "Oversizing the solar array has the potential to increase the system yield". 

 

I'm getting something wrong? or Should I not be using this automatic sizing factor from PVSol?

 

Best regards
