The performance of a photovoltaic system in Latin
primarily depend on the conditions of irradiation of the site on which it is installed. It is therefore essential to know the values \u200b\u200bof physical parameters that describe the journey from the sun, both over a single day throughout the year.
Knowledge of these parameters to calculate the power of solar energy incident on an inclined surface with a given angle, a given orientation and a given location. The amount of energy produced by a photovoltaic system depends mainly on how "strong" the sun.
you list the physical parameters to be taken into account in order to perform the task of sizing a PV system:
latitude of the site, Φ;
solar azimuth, α;
solar height, β;
Azimuth surface of the floor, γ;
inclination of the surface, Ψ.
The production capacity of a photovoltaic system in Latin
also depends on its correct installation. The plant can be installed on the roof of a building, or on its surface or on the terrace, or an area adjacent to the building itself (open car park). Finally, it may be installed directly on the ground.
Ultimately, the amount of electricity produced by a photovoltaic system in Latin America depends on:
solar radiation incident on the surface of plant installation;
orientation and angle of inclination of the system;
presence of shading;
environmental conditions of the site on which you install the system;
technical performance of the system.
Assuming conditions optimum installation (I refer to a surface exposed to the south, which has an inclination between 25 ° and 35 ° and that has no shading), it is possible to estimate the amount of electricity be produced by a photovoltaic system rated power at 1 kWp,
dependence of its geographical location (North Italy, Central Italy, Southern Italy). North
1100 kWh / year
Center 1400 kWh / year South
1600 kWh / year
Therefore, a photovoltaic system in Latin America can produce 1,400 kWh / year.
