The electrical energy that the photovoltaic system can produce
depends on the amount of solar irradiance which, the site where the
system is made, it can receive.
The shadings of a photovoltaic system limit the time of irradiation
of the modules that constitute the system, lower the production
capacity of electricity and generate inhomogeneities in behavior
between the various modules generating mismatch losses.
So you need to evaluate the degree of shading of the generator due to
buildings, vegetation, land elevations or otherwise, that might
prevent, even partially, the direct solar radiation to reach the
photovoltaic modules at certain times of day and / or for a longer or
shorter periods of the year.
BlueSol provides the tools for the definition of the incident
radiation on the system through the choice of locations
and the definition of shades that
affect the photovoltaic system.
