“…For the traditional and stepped solar stills, the coefficient of determination of the predicted outcomes is strong, at 0.97 and 0.99, respectively. Bagher Mokhtari Shahdost et al [25] due to rising greenhouse gas emissions and high energy prices, it is now more important than ever to utilise renewable energy sources in many industrial applications. The highest quantity of fuel that can be saved using solar energy for the examined furnace is 1,996,000 m3 per year, which is roughly 23.8 percent of the furnace's fuel consumption and is responsible for 3557.7 tonnes of CO2 emissions per year in the best-case scenario.…”

“…Solar energy is the most important energies that man can exploit; because it is renewable energy and is not exhaustible and does not result in gases or by-products harmful to the environment compared to other sources of energy (Ahmed, 2016;Ahmed, 2017;Mohammadnezami et al, 2015), and researchers have done a lot of research in this area and suggested many ways to develop and exploit this energy, like the reflective mirrors (Shahdost et al, 2019) to collect solar light and other ways to absorb solar energy, such solar cells that enable us to obtain electricity directly from the sun (Ahmed and Mohammed, 2017a).…”

Hybrid solar collector (PV/T) is designed to produce electricity, hot water, or hot air at the same time as they operate solar cells and solar heaters in one system. This system is designed to increase the electrical efficiency of solar cells by absorbing heat from these cells. The fuzzy logic (FL) is a tool usually used to optimize the operation of the systems. In this paper, the FL is to monitor and correct the mainsystem parameters to remain optimization efficiency at a better level. Three affected variables were studied: Effect of reflective mirrors, the effect of the glass cover, and the effect of the lower reflector angle on the performance of the PV / T hybrid solar system. These three parameters are traveled to be inputs for the FL, and the PV temperature in addition to system efficiency is the output for it. The effect of solar radiation was found to have a great effect on the efficiency of the hybrid solar collector. The thermal efficiency was 82% for the given value of the PV and mirrors, while the efficiency down to 50 for another angle. By using the artificial intelligent the system behavior depends on its output, which called feedback close loop control, at a real-time process that optimizes the system efficiency and its output. ©2020.

Summary We report on the development of non‐tracking solar concentrator troughs designed subject to the condition that they operate efficiently for diffuse irradiation from all angles during daylight hours. Troughs of the usual compound parabolic form were considered initially. Remarkably however, the most efficient shape for the above requirement turns out to be a trough of simple semi‐circular cross‐section incorporating a tube of height equal to the circle radius and with a planar absorber plate placed vertically. This trough has a limited concentration ratio of exactly 2.0 but an intercept factor for incident radiation of 100% for all angles of incidence. This desirable feature is explained from the properties of caustics arising from reflection of incident light at the semi‐circular trough (SCT) surface. This very simplest of trough design has the clear advantages of small size and low‐cost of manufacture. Experimental tests conducted under varying solar irradiation conditions, demonstrate that the simple step of placing an evacuated tube in a SCT can lead to a power output gain of a factor of at least 1.7 on average.
