Photovoltaic solar energy is the energy the Sun that is converted into electrical
energy directly, without any intermediate conversion. For this energy to be used
properly and efficiently, a special technological system called photovoltaic
system is needed. In the present project, the evaluation of photovoltaic modules
in different conditions is considered: dirty, clean and humid, for the
development of a cooling and cleaning device of these. In evaluating of modules,
it saw an improvement in the efficiency of electrical production, between the
wet and clean module against dirt, because the temperature found. When
analyzing the results obtained, an automated cooling-cleaning device was
implemented, decreasing the temperature of the module, maintaining optimum
characteristics for greater use of incised energy and reducing electrical losses.
The operation of the system is composed of thermal sensors that upon
perceiving the maximum temperature of the indicated photovoltaic module, the
device is activated by dropping water which is captured by a container for
recirculation in the system.
In the implementation of the system, an increase of 27% of power was obtained
with respect to a temperature decrease of 40% compared to the dirty
photovoltaic module.
