Do you Need To Check Your PV Panel/Array Performance?
There are many variable factors involved in being able to accurately predict PV Array performance. These variations occur in real time and affect the final power output of the array. Initial estimates can be different from true performance in the field. Factors such as Radiance, Temperature & Load all affect the output performance of the PV panel. Lack of maintenance will also have an impact.
A realistic performance check can be done in the field under actual environments conditions where Radiance and Temperature are constantly changing. In this way real time data of the actual output watts of the solar array can be collected and used to determine performance acceptability based on predetermined criterion.
