Predicting a solar field´s power output, while considering environmental conditions

Being able to give a preliminary estimation of a solar field annual power output is of paramount importance, especially when dealing with large fields. The Cost of constructing such a field is very high, and the time it takes to repay itself is usually about a decade. It is shown that the 10-parameter solar cell model can be employed to suit any functional solar module which was tested in order to obtain its parameters. Then, the virtual parameters of a 10-parameter model of an entire panel (modeled as a large cell) can be obtained, and a running model for the entire field is deduced. To predict the field output, the sun elevation needs to be estimated annually as well. Using Woolf´s equations, another Simulink model was constructed, delivering a 10 minute vector of samples of the sun´s height all year-round.
