Currently in the world there are a lot of technologies that are being used to take advantage of
the solar energy, which is the most clean and abundant of the renewable energies. The
technology most used in this field is the photovoltaic, where the most of the photovoltaic
cells are made of silicon, which is one of the chemical elements more aboundant in nature.
Of this technology mainly there are two types of photovoltaic cells of silicon,
monocrystalline and polycrystalline. The efficiency of these cells is determinated for their
manufacturers in contolled conditions and tipically is up to 14% in commercial panels.
Besides of being low, the efficiency of the panels is afected by external factors, like the
temperature or the humidity. For this reason there are several researches in differents regions
in the world about the influence that have their own climate in the efficiency of the
photovolaic panels.
The present work has been made to find out the relationship between the efficiency of these
two types of photovoltaics panels, monocrystalline and polycristalline, and the weather
variation in the city of Bogota-Colombia. The power generated of two photovoltaic panels,
one monocrystlline and one polycristalline, were collected during one month the 24 hours in
condition of variant weather. At the same time it was implemented one wheater station that
registered the variations of climatic variables like wind speed, temperature, humedity,
irradiance and rain, in order to relate them with the generated power of each photovoltaic
panel.
Once with this information collected it was made one study with all the correlated variables
through of the stadistic tool PCA (Principals Components Analisys) where it can see the
impact of each climatic variable over the generated power in both panels and therefore its
impact over the efficiency. |
