“…It was observed that in addition to help keeping the PV surface clean, the water reduced the reflection loss by 2 to 3.6% and decreased the cell temperatures up to 22 • C. Moreover, the electrical yield returned a surplus of 10.3% and a net gain of 8 to 9% was achieved even when parasitic power consumption to run the pump is accounted. In an another work, Odehand and Behnia [21] cooled the PV panel by introducing water trickling configuration on the upper surface of the panel. They observed that the PV module surface temperature in a typical summer day was reduced to about 26 • C from 58 • C. Their results also showed an increase of output power in the range of 4 to 10% when cooling technique was adopted.…”

“…Such type of PV array arrangement allows for maximum power output and optimum invertor operation. High temperature increases the panel surface temperature and consequently may drop the panel output in the range of 4-10% [9]. Contrarily, low ambient temperature decreases PV surface temperature and may increase PV array output by the same percentage.…”

“…Although these assessment methods are applicable to the different power generator, solar power generators require some other considerations. The intermittent solar irradiation, system orientation, and of other weather conditions affect dramatically the long term performance [9]. The major performance assessment methods of solar PV power generators found in the literature are summarized by the following five indicators:…”

This paper assesses 4 years of operation of a 1.75 kW roof top solar PV system installed in a Sydney suburban house. The system consists of 10 PV panels, a DC/AC inverter, and a grid connected gross meter. Solar electricity delivered to grid is verified with the results from a computer simulation package (PVSYST) by adopting the installed component specifications, operation conditions, and weather data of the site. The results show high consistency between the values of energy delivered to the grid measured by the energy company and the energy estimated by system simulation. New system performance indicator is developed and called the optimum performance compliance ratio (P CR ). It is a measure of the compliance of the output of the designed PV system with the output which would be produced by the same system with a solar tracker. This indicator provides system designers, contractors and energy providers with the actual capacity of the system that they can offer the end-users.

Ordóñez, "Mejoramiento del desempeño de paneles fotovoltaicos a partir de la irrigación forzada de la superficie superior", UIS RESUMENLa irrigación de la superficie superior de los paneles fotovoltaicos (FV) es uno de los métodos más efectivos para reducir su temperatura de operación e incrementar la potencia generada. Aunque existen publicaciones sobre esta técnica, hay poca información sobre el efecto de las variaciones del tiempo de irrigación y caudal de riego. Este trabajo presenta un estudio experimental sobre el efecto de estos dos factores para un panel FV de 255 W instalado en un entorno de clima cálido tropical. Se encontró que caudales de 4.5 l/min o superiores pueden producir incrementos de hasta 10% en la energía generada adicional diaria; adicionalmente, que los tiempos de irrigación tienen una significativa influencia en la disminución de la temperatura de operación promedio y la energía adicional generada por un panel FV. PALABRAS CLAVE:Generación fotovoltaica, Irrigación, Mitigación térmica. ABSTRACTIrrigation on upper surface of the PV panels is one of the most effective methods to reduce the operating temperature and to increase the PV power. Although there are publications about this technique, there is little information about the effect of the time and irrigation flow variations on the PV performance. This article presents an experimental study about the effect of both factor for a PV panel of 255 W installed in an warm -tropical place. It was found that flows of 4.5 l/min o higher can produce increases up to 10% in additional generated energy per day; in addition, irrigation time has a significant influence on the average operating temperature decreases and additional generated energy per day.
