“…The results should be evaluated and compared with other regions of the country in the light of this information. In studies conducted for Balıkesir [27], Tekirdağ [28], Manisa [29], Şanlıurfa [30], and Batman [31] provinces, the approximate electrical efficiency of PV panels was 12%, 15%, 13.5%, 6.5-7% and 13.65%, respectively while the yields of monocrystalline and polycrystalline panels, in this study conducted in Sinop, were found to be as 16.2% and 13.9%, respectively.…”

Due to the increase in energy consumption and environmental pollution in recent years, countries have included renewable energy in their long-term energy policies by supporting researches to increase the usage diversity and performance of renewable energy sources. Solar energy, one of these renewable energy types, and its various applications are of great importance to increase the energy production diversity. In this context, evaluation of monocrystalline and polycrystalline photovoltaic panel performance was performed under Sinop's climate conditions. In the first stage, the most suitable panel tilt for Sinop province was found by recording the voltage and current values of the panels at different panel angles. According to the results obtained, the optimum angle value of the monocrystalline and polycrystalline panels was determined as 38 degrees. Then, in different days, the efficiencies of the panels were calculated using the determined optimum angle and compared with the literature. At the same angles, it was observed that the monocrystalline panel produced higher power than the polycrystalline panel and the monocrystalline panel was more efficient when examined from hourly measurements. Experimental panel yields were found to be 0.162 and 0.139 for monocrystalline and polycrystalline panels, respectively. Finally, the effect of temperature change on the panels was evaluated. With this study, the most suitable panel type is determined for Sinop province and its surrounding conditions, thus preventing unnecessary investments and efficiency losses.

“…Some studies have explored the influence of inlet water temperature on cooling effect, as it determines the heat transfer effect between the water and solar cells. When inlet water temperature is low, the temperature difference between water and solar cells is high, leading to more heat removable from PV modules and better cooling effect [60,61]. Zhang et al [49] have revealed that when decreasing the inlet temperature from 35°C to 15°C, cell temperature could be lowered by up to 9°C.…”

When converting solar energy to electricity, a big proportion of energy is not converted for electricity but for heating PV cells, resulting in increased cell temperature and reduced electrical efficiency. Many cooling technologies have been developed and used for PV modules to lower cell temperature and boost electric energy yield. However, little crucial review work was proposed to comment cooling technologies for PV modules. Therefore, this paper has provided a thorough review of the up-to-date development of existing cooling technologies for PV modules and given appropriate comments, comparisons and discussions. According to the ways or principles of cooling, existing cooling technologies have been classified as fluid medium cooling (air cooling, water cooling and nanofluids cooling), optimizing structural configuration cooling and phase change materials cooling.Potential influential factors and sub-methods were collected from the review work, and their contributions and impact have been discussed to guide future studies. Although most cooling technologies reviewed in this paper are matured, there are still problems need to be solved, such as the choice of cooling fluid and its usability for specific regions, the fouling accumulation and cleaning of enhanced heat exchangers with complex structures, the balance between cooling cost and net efficiency of PV modules, the cooling of circulating water in tropical areas and the freezing of circulating water in cold areas. To be advocated, due to efficient heat transfer and spectral filter characters, nanofluids can promote the effective matching of solar energy at both spectral and spatial scales to achieve orderly energy utilization.
