“…Moreover, it should be noted that the higher level of efficiency reached by the module with the cooling mechanism is due to the higher amount of power generated by the module as seen from figure 5. The result of figure 6 agrees with earlier research by Govardhanan et al [28] which report that due to cooling, the output power and efficiency of the module was enhanced.…”

Africa and Nigeria in particular are blessed with abundance of sunshine throughout the year. Unfortunately, the region is associated with high temperature values which is a major factor militating against the efficiency of photovoltaic systems in use today. Since for each degree rise in temperature, about 0.50% efficiency is lost, then this implies that once a photovoltaic panel enters the Nigeria atmosphere about 5%-10% of its maximum power is lost. To tackle this problem, a cooling mechanism has to be incorporated into photovoltaic system design for adequate cooling and temperature monitoring. A smart automatic cooling mechanism and a smart photovoltaic MPPT tester were deployed in the study. In situ measurements were obtained in outdoor real-time conditions. The results reveal better performances for voltage, current, power and efficiency for the photovoltaic module whose temperatures was regulated not to exceed the threshold temperature of 350C. This study shows and suggest that lowering the panel temperature of photovoltaics through the application of cooling mechanism should be considered in the design of photovoltaic systems.

“…Their results revealed that the heat sink raised the open circuit voltage by 10%. While Govardhanan et al [28] experimentally investigated a PV module with uniform water flow on its surface for adequate cooling. Their report shows that due to cooling, the output power and efficiency of the module was enhanced by 15% and 14% respectively.…”

“…Thus, it was established that cooling the panel was effective in improving its e ciency and conserving water. In a separate study [13], the photovoltaic panel was cooled by having three distinct ows of uniform water go over the top surface of the panel, which was supplied from the tank which was mounted on the top of the panel. It was concluded that cooling the PV module reduced the panel temperature by 30%, resulting in increased power production from 19 watts to 23 watts.…”

In this study a front surface spray water cooling system with a zigzag pattern was experimentally and theoretically designed and investigated. Since the effectiveness of any photovoltaic panels can be adversely affected by various weather-related conditions such as solar radiation intensity, ambient temperature and dust accumulation, and the temperature and rate of flow of water that is used for cooling. ANSYS Fluent was utilized to predict the effects of the proposed system on photovoltaic (PV) power production. The findings indicated that the proposed system, when operating at a rate of 5 L/min water, enhanced efficiency of PV by 20.25%, whilst providing a pristine and dust-free surface. The simulation results indicated that the solar radiation is mostly affecting parameter in increasing the power production with implementation of water-cooling system, upon an increase of 100 watt/m2 in solar radiation, the PV power production augmented by 16.6%. Furthermore, decreasing the water inlet temperature by 5°C with a 5 L/min volume flow rate resulted in an increase in panel power production by 2.25%. Though, the ambient temperature has a slight influence on PV power production at all water volume flow rates.

“…As such, there are many cooling techniques available in the literature. For instance, a passive air-cooled system [13], [14], closed loop water cooling system [15], air-cooled system [16], and water sparkling system [17] as shown in Figure 3 respectively. Passive air-cooled system uses heat sinks as a heat transfer that can transfer the heat from a high thermal energy to a low temperature side and then cooled-up by the surrounding air.…”

Harvesting energy from the sun makes the photovoltaic (PV) power generation a promising technology. To obtain a consistent state of charge (SOC), consistent energy must be harvested and efficiently directed to the battery. Overcharging or undercharging phenomena decreases the lifetime of the battery. Besides, the effect of irradiance toward solar in term of sunlight intensity effects the efficiency and hence, sluggish the SOC. The main problem of the solar panel revealed when the temperature has increased, the efficiency of solar panel will also be decreased. This manuscript reports the finding of developing an automatic active cooling system for a solar panel with a real time energy monitoring system with internet-of-things (IoT) facility. The IoT technology assists user to measure the efficiency of the solar panel and SOC of the battery in real time from any locations. The automatic active cooling system is designed to improve the efficiency of the solar panel. The effectiveness of the proposed system is proven via the analysis of the effect of active cooling toward efficiency and SOC of photovoltaic system. The results also tabulate the comparative studies of active-to-passive cooling system, as well as the effect of cooling towards SOC and efficiency of the solar panel.
