Hello everybody,
I'm interested in obtaining the annual power production of a single solar cell. For that I have done the input of a timeseries in Simulink where the first column is the annual hours (01-12-2017 12:00:00, for example) and the second is the correspondent radiation in Wh/m2).
How do I obtain the power produced for the complete input time?
Thank you so much, Sofia

You can write a program for that, with irradiance as input and maximum power from the cell as output. So for each time you can calculate the maximum power the cell can generate. You can calculate the total energy the cell can produce in a year from this.

I end up writing a for loop (from 1 to 8760 hours) in which the irradiance for each cell is send as an input to simscape individually and the maximum power point is send as an output to the Matlab's workspace. However, this procedure is time exhausting.
Do you know the units of the maximum power point output? Since the input irradiance must be in Wh/m^2, I'm guessing W/m^2? The solar cells don't have an area parameter.
Thanks, Sofia

You don't need to go to simulink for that. You can model the solar in a m-file and use it for calculating the power.
The unit of irradiance is W/m^2. The power output is in Watt (W). You can refer this datasheet for more information about units. Tata Solar

I need to simulate using simulink because I'm doing a simulation of a bifacial panel, so actually I have 120 values of irradiation.
