The present work proposed the simulation of photovoltaic systems developing partial
shading effects and the analysis of their adjustments. There is a range of advantages in
shading analysis even before the execution of the photovoltaic project where they are:
Knowing the shape of the shadow and its orientation, facilitating the location for installing
the modules; evaluate the average shading that a surface experiences over a period of 12
months. For a more detailed analysis regarding the photovoltaic devices, note the
importance of establishing as their characteristics under the real operating conditions,
where the characteristics of each module are determined according to the maximum
output power, according to the test conditions. standard. For this, it is necessary to verify
the functional tests and labeling of the photovoltaic modules. It is necessary to use
irradiation, temperature and air mass standards in order to standardize how measures and
facilitate the values compared between modules and standard measures. The procedures
performed were simulations with different conditions and module layouts, with string
inverters, microinverters and power optimizers. Where the highest percentage of income
was with microinverters reaching 83.2%. |
