“…High humidity also has the potential to form tiny water droplets on the surface of the panel which can reflect and refract incoming light rays away from the active silicon layer as well as causing delamination and corrosion of the metal contacts and interconnects in the PV system, impacting negatively on the performance [40,41].

“…This results in the built-up of thermal energy within the panel and hence increase in panel temperature that have adverse effects on the conversion efficiency and panel effective life. The negative influence of soiling has been observed to manifest mainly via the short circuit current and power output with a weak influence on the open circuit voltage (see Figure 9 and Figure 10) [38,42,43].…”

Photovoltaic (PV) panels have attracted a lot of research interest in the past decade due to their clean and renewable character as an energy source. However, their intrinsic low conversion efficiency has been a major drawback, imposing the need for a huge initial cost of investment. Additionally, due to the low efficiency, PV system installations also require large surface area for panel installation. External factors such as temperature and soiling and shading further reduce the performance of the PV panels operation under real world conditions. Furthermore, the processes used in the fabrication of PV panels do not allow the improvement of panel efficiency once the fabrication is completed. Thus special techniques are required for the modulation of performance on the field. Thermal management schemes and cleaning techniques have been developed to alleviate this existential challenge. Additionally, PV panels operation in the field has been boosted via the improvement of the solar collection methods such as solar trackers, solar concentrators and panel tilt angle. This paper presents a critical comprehensive review of the different PV panel technologies and their field operation challenges as well as the strategies used to enhance the performance of silicon photovoltaic modules (the most attractive single junction PV panels in the market) under field conditions.

During the twentieth and twenty-first centuries, the oil industry has been pivotal in influencing all countries’ geopolitical, economic, and human development strategies. Until recently, the debate was about peak oil and what would happen after oil finished. However, due to technological advances and hydraulic fracturing, shale oil formations have become economically viable due to the United States’ desire to achieve energy security to make a qualitative shift in the oil industry and the geopolitics of oil. Therefore, this paper deals with an economic model that illustrates the impact of oil price fluctuations to the shale oil and gas companies by analyzing the main determinants of continuity of shale oil and gas companies in production if global oil prices decline or rise. In addition, the study will investigate the effects of OPEC+ policy and Covid-19 on the future of shale oil industry. The study will discuss some future scenarios for global energy trends and predict what the shale industry will look like in the future. The study concluded the shale industry faces an internal destructive process (within the industry itself) and external (Renewable energy, OPEC and Covid-19). The stability of oil prices is a critical factor that promotes the shale industry's recovery. However, shale industry is expected to continue with low productivity growth rates and continuing government support for it.

An Improved Approach to Enhance Training Performance of ANN and the Prediction of PV Power for Any Time-Span without the Presence of Real-Time Weather Data

In this work, an improved approach to enhance the training performance of an Artificial Neural Network (ANN) for prediction of the output of renewable energy systems is proposed. Using the proposed approach, a significant reduction of the Mean Squared Error (MSE) in training performance is achieved, specifically from 4.45 × 10−7 to 3.19 × 10−10. Moreover, a simplified application of the already trained ANN is introduced through which photovoltaic (PV) output can be predicted without the availability of real-time current weather data. Moreover, unlike the existing prediction models, which ask the user to apply multiple inputs in order to forecast power, the proposed model requires only the set of dates specifying forecasting period as the input for prediction purposes. Moreover, in the presence of the historical weather data this model is able to predict PV power for different time spans rather than only for a fixed period. The prediction accuracy of the proposed model has been validated by comparing the predicted power values with the actual ones under different weather conditions. To calculate actual power, the data were obtained from the National Renewable Energy Laboratory (NREL), USA and from the Universiti Teknologi Malaysia (UTM), Malaysia. It is envisaged that the proposed model can be easily handled by a non-technical user to assess the feasibility of the photovoltaic solar energy system before its installation.
