Solar energy usage is thriving day by day. These solar panels are installed to absorb solar energy and produce electrical energy. As a result, the efficiency of solar panels depends on different environmental factors, namely, air temperature, dust (aerosols and accumulated dust), and solar incidence, and photovoltaic panel angles. The effects of real conditions factors on power and efficiency of photovoltaic panels are studied in this paper through testing the panel in real environmental tests. To study the mentioned parameters precisely, two panels with different angles are used. The case study is regarding a region of Tehran, Iran, in summer and winter seasons. The results show that panel efficiency during winter is higher than summer due to air temperature decrement. It is discovered that among air pollutants, Al and Fe have the most share in polluting the air that affect the photovoltaic efficiency. Moreover, measuring the accumulated dust on the panels shows more amount in winter in comparison with summer. The important point in studying the effect of tilt angle is that inconformity between solar incidence and photovoltaic panel angles would result in solar radiation absorption and eventually panel efficiency loss and also, photovoltaic panel installation angle would affect the amount of dust deposited on its surface.

Growing demands for cleaner energy sources lead to innovations that require investigations in solar energy harvesting. Though numerous organic and inorganic photovoltaic devices have been explored for the solar power conversion, achieving a high efficiency is still an open challenge for the researchers. In this context, an efficient, self-adjusting solar power panel coupled with low-cost and high reliability is of great significance and demand. In this study, we investigate the potential of Shape Memory Alloy (SMA) actuators for solar tracking applications. Three SMA configurations were considered containing one and up to three SMAs arranged in parallel. The temperature range for the displacement experiments was 40°–60°. Additionally, three levels of mass were used, namely, 500 g, 600 g, and 700 g. The displacement experiments revealed that the addition of more SMAs into the configuration provided a more consistent performance. The force experiment revealed that two-SMA configuration achieved 60% higher force production compared to the one-SMA configuration under the same conditions while the three-SMA configuration was 31% higher than in the two-SMA configuration and 110% compared to the one-SMA configuration. Additionally, the force hysteresis of the two-SMA setup was smaller and closer to that of single-SMA configuration. The two-SMA configuration force hysteresis exhibited a more linear trend as compared to that of the three-SMA configuration. The outcomes of this work highlight the potential of using SMAs as actuators in solar-powered applications and that optimization in terms of the needed number of SMAs is required to meet the displacement and/or force requirements.
