“…Solar panel power losses with installation at 1m height, 20° inclination, and 0° azimuth Losses are introduced in various parts of the system such as solar panels, wires and transformers. The most common losses are temperature losses from 5% to 15%, angular and spectral losses 0.5-7%, dirty and twilight 0.5-4.5%, mismatch 2-4% and others, which is consistent with the results of similar studies (Almonacid, et al, 2011;Adekanbi et al, 2023). The air conditioning system can be analyzed as presented in Table 1.…”

The extensive use of fossil fuels contributes to global warming and the release of toxic metals into the environment, resulting in climate change in some regions. It has been estimated that cooling buildings accounts for about 20% of global electricity consumption and this figure continues to grow. The purpose of the current study is to evaluate the feasibility of using an air conditioning unit for cooling a residential building, powered by solar energy in the conditions of Iraqi Kurdistan. Such an assessment is required for the sustainable development of the region. The study location is Erbil city in Iraq (latitude: 36.1911 °N, longitude: 44.00917 °E). The PVsyst software tool was used for modeling because it is characterized by great versatility in the field of modeling solar energy systems. The specified solar panel power (kW) was a constant parameter. Variable parameters were height of solar panels, albedo reflector, tracker system. In the current study, three simulations were performed in which the variable parameter was height and four simulations in which the variable parameter was the solar panel› angle. An average of 3.5 kWh was produced throughout the day, and an average of 3.3 kWh was produced during working hours. Only 0.2 kWh was produced outside of working hours, meaning that almost all of the electricity produced is available during working hours. This is useful in countries without high feed-in tariffs where only a small feed into the grid is needed. Also with the lowest calculated values (of all the options under study) the energy produced is 2264 kW/h/year or 2.264 MW/h/year (month -January, panel installation height -0.5 m, inclination -20°, azimuth -0°), greenhouse gas emissions of at least 604.3 kg CO 2 per year are eliminated. At the same time, an additional measure to increase the efficiency of using a solar panel to power an air conditioner is to place reflective material in which the reflection rate or reflection coefficient is different under the solar panels. However, as mentioned earlier, this is an expensive solution. In the future, it will be beneficial to develop smart control technologies to improve performance and evaluate the impact of a solar air conditioning.

“…In the first stage is the Mehranfar et al [59] emphasized that the use of solar chimney power plants (SCPPs) to produce clean and environmentally friendly electricity has gained significant interest in recent years and is now considered one of the most promising solutions in the world of solar energy. Adekanbi et al [60] discovered that soiling lowered solar efficiency, raised maintenance expenses, and reduced the lifespan of PV panels. Naimoglu and Akal [61] highlighted that decreasing CO 2 emissions is positively affected by technical advancement, energy efficiency, and the use of renewable energy sources.…”

The globe is transitioning from traditional methods of electricity generation to renewable resources in order to achieve sustainable goals. Solar energy is a promising and abundant renewable resource that shows great potential as a viable alternative to traditional energy. Furthermore, the production of electricity from solar energy is the most cost-effective compared to other kinds of renewable energy. Nevertheless, the execution of solar initiatives in underdeveloped nations is encountering several obstacles. Identifying the most significant obstacles in the execution of solar projects is of utmost importance. This study uses a linear regression model (LRM) and an analytical hierarchical process (AHP) to determine the main barriers to the implementation of renewable energy projects in a developing economy, i.e., Pakistan. By conducting an extensive review of the relevant literature and consulting with experts, the most significant categories of obstacles were determined. A survey based on 429 responses was collected from the participants working at solar projects. Subsequently, the responses were subjected to processing and analysis using the relative importance index (RII), AHP, and linear regression modeling techniques. The linear regression analysis revealed several significant variables that hinder progress, including financial conditions, policies, technological awareness, institutional support, social and environmental awareness, market stability, and other miscellaneous factors. The AHP analysis revealed the key factors that have the greatest impact, which include effective policies, financial stability, technological expertise, institutional support, market stability, various aspects, and social and environmental awareness. The study’s conclusions are beneficial for all stakeholders and project managers in enhancing the project management of solar initiatives. It would also facilitate prompt decision-making regarding policy formulation and implementation.

“…The literature review shows results that highlight energy losses in solar photovoltaic (PV) systems, which can reduce the performance and profitability of the system, impacting its ability to generate electricity. There are two types of factors: technical and non-technical (Adekanbi et al 2024). These losses can occur due to external conditions such as weather, climate, location, and within the solar PV modules themselves, caused by shading, dirt, mismatch, degradation, and wiring.…”

“…The search results provide insights into the sources of energy losses in solar PV systems and how to minimize them. The articles suggest that to reduce environmental losses, a suitable location with high solar irradiance, low temperature, and low humidity throughout the year should be selected (Adekanbi et al 2024).…”
