“…En instalaciones PV, a más de estos factores, la temperatura superficial de los módulos fotovoltaicos también afecta a la eficiencia del sistema [25][26][27][28]. Adicionalmente, es necesario considerar los aspectos económicos y las demandas energéticas, para así maximizar la producción en los momentos de mayor demanda o de mayor costo energético [29].…”

Esta investigación calibra y valida un modelo de sistemas fotovoltaicos monocristalinos en la herramienta computacional System Advisor Model (SAM) para simulación de generación eléctrica, considerando las características meteorológicas en Cuenca (Ecuador), ciudad en altura próxima a la línea ecuatorial. Se obtiene el rendimiento eléctrico al desplegarse paneles fotovoltaicos de características específicas, con inclinaciones que responden a techumbres típicas locales y distintas orientaciones. Se calcula la eficiencia con mediciones in situ durante un período de 18 días, para que, con datos meteorológicos se calibre un archivo climático para el año 2016. Se estiman rendimientos anuales acorde a inclinación y orientación, y a características técnicas de los fotovoltaicos. Se detectan pérdidas por acumulación de suciedad e incremento de temperatura de las placas. Se valida el modelo mediante una regresión lineal, al comparar los valores simulados con los datos obtenidos de mediciones in situ de un panel en posición horizontal. Los resultados indican una pérdida promedio de eficiencia de 2,77 % por condiciones de suciedad y de hasta el 30 % por incremento de temperatura. La validación del modelo mostró un coeficiente de determinación R2 = 0,996 y un RMSE normalizado de 8,16 %. Se concluye además que, por la latitud particular del sitio en estudio, a diferencia de la mayor parte del planeta, la disposición de paneles fotovoltaicos en cualquier orientación considerando pendientes bajas, no reduce significativamente el rendimiento en la generación de energía eléctrica anual.

“…In procedure section of NOCT testing under 10.5.3.4, stated that data of SI has to be greater than 400 W/m 2 [3]. Tropical regions are areas of having fast-changing SI with plenty of clouds, high AT and high relative humidity (RH) [9], [10]. Based on the preliminary study conducted in evaluating the SRE for NOCT testing in Malaysia, the median SI was 300 W/m 2 [7].…”

This paper presents the establishment of Standard Reference Environment (SRE) for photovoltaic (PV) Nominal Operating Cell Temperature (NOCT) testing in Malaysia representing one of the countries that lies in tropical region. From a field testing conducted, 12-months data of six parameters namely solar irradiance (SI), ambient temperature (AT), relative humidity (RH), wind speed (WS), wind direction (WD), module temperature (MT) and open circuit voltage were analysed to determine the median SI and the median AT. From the analysis, the median SI and the median AT are 228 W/m2 and 30 °C respectively. However, these results show that the current approach in determining SRE using median ambient parameters is not suitable for tropical Malaysia based on the percentage error of approximately 30 %. Due to this, the proposed approach applied in this study is determining the corresponding AT of the same SI (800 W/m2) used in present SRE of international standard. Thus, the new proposed SI and AT for SRE in this study are 800W/m2 and 31°C respectively. The SRE found in this study is determined using dedicated approach to suit tropical climate in deriving a more accurate NOCT for tropical region.

“…Many efforts have been made to investigate and enhance the performance of photovoltaic modules. Ying et al [6] investigated the performance of five different solar modules in Singapore (Tropical climates), results showed that wafer based silicone solar module was not much influenced by the varying irradiance and c-Si solar module have showed higher efficiency at higher irradiance but dependent on the module temperature. Bashir et al [7] showed that efficiency of c-Si solar module was better than amorphous solar module but the performance ratio of amorphous crystalline solar module was observed higher than c-Si and p-Si due to better performance under low light conditions.…”

Photovoltaic modules have a potential market for off-grid applications in rural context with limited access to the electrical grid. For fixed photovoltaic systems, proper orientation of photovoltaic modules at specific conditions plays a significant role to have maximum performance. This paper presents the effects of different metrological parameters on the performance of photovoltaic modules at three different inclination angles (0°, 33.74° and 90°) with horizontal. Six 40W photovoltaic modules (three monocrystalline and three polycrystalline) were exposed to sunlight at three different inclination angles. Performance ratio, module efficiency, fill factor were calculated for photovoltaic module at different inclination angles and results presented. PV modules at 33.74° tilt angle received high solar radiation and showed high output power. As solar radiation increases, the radiation losses from the surface of the module increases and resultant decrease the module efficiency and increase the module temperature at high solar irradiance. During the winter months, the average efficiency of the monocrystalline PV module at 0° and 90° was 4% and 2% higher respectively than the 33.74° tilt angle. Similarly polycrystalline PV module showed 7% and 5% higher efficiency at 0° and 90° respectively than the 33.74°. Moreover, Fill factor of PV module at 33.74° tilt angle had the highest value as compared to other tilt angles.
