Due to rapid urbanization, inclination in the energy demand has been experienced in the recent years which posed the threat of energy security and global warming. Artificial lighting in buildings shares an impactful amount of energy consumption, which needs to be minimize. Semitransparent building integrated photovoltaic (BIPV) cells have the potential of generating clean energy and allowing the daylight harvesting in the building, which can minimize the energy consumption across lighting by a great extent. In this paper opportunities of energy saving across low voltage DC (LVDC) nanogrid powered LED lighting in an industrial building by considering daylight harvesting and BIPV cells has been investigated. Results reflects that a significant amount of energy can be conserved across LED lighting by utilizing BIPV cells which allows daylight through it in the room. Moreover, a notable amount of clean energy can also be generated using semitransparent BIPV cells.

In photovoltaic (PV) systems, maximum power point tracking (MPPT) techniques are used to track the maximum power from the PV array under the change in irradiance and temperature conditions. The perturb and observe (P&O) is one of the most widely used MPPT techniques in recent times due to its simple implementation and improved performance. However, the P&O has limitations such as oscillation around the MPP during which time the P&O algorithm will become confused due to rapidly changing atmospheric conditions. To overcome the above limitation, this paper uses the fuzzy logic controller (FLC) to track the maximum power from the PV system under different irradiance, integrates it with a DC-DC boost converter as a tracker. The result of the FLC performance is compared with the traditional P&O method and shows the MPPT algorithm based on FLC ensures continuous tracking of the maximum power within a short period compared with the traditional P&O method. Besides that, the proposed method (FLC) has a faster dynamic response and low oscillations at the operating point around the MPP under steady-state conditions and dynamic change in irradiance.

Considering the recent drop (up to 86%) in photovoltaic (PV) module prices from 2010 to 2017, many countries have shown interest in investing in PV plants to meet their energy demand. In this study, a detailed design methodology is presented to achieve high benefits with low installation, maintenance and operation costs of PV plants. This procedure includes in detail the semi-hourly average time meteorological data from the location to maximise the accuracy and detailed characteristics of different PV modules and inverters. The minimum levelised cost of energy (LCOE) and maximum annual energy are the objective functions in this proposed procedure, whereas the design variables are the number of series and parallel PV modules, the number of PV module lines per row, tilt angle and orientation, inter-row space, PV module type, and inverter structure. The design problem was solved using a recent hybrid algorithm, namely, the grey wolf optimiser-sine cosine algorithm. The high performance for LCOE-based design optimisation in economic terms with lower installation, maintenance and operation costs than that resulting from the use of maximum annual energy objective function by 12%. Moreover, sensitivity analysis showed that the PV plant performance can be improved by decreasing the PV module annual reduction coefficient.

Temperature and solar radiation have large effects on the performance of photovoltaic (PV) systems. PV cell temperature is related to the ambient temperature, while the solar radiation incident on PV surface depends on the slope and azimuth of the PV panels. Furthermore, ground reflectance (albedo) affects the solar radiation incident on the PV surface and hence influences its performance. Nevertheless, the impact of some important factors on the PV performance such as the ground reflectance at different tilt angles and temperature coefficient of power under Middle East (temperate) climatic conditions are scarcely reported. In this research paper, a techno-economic analysis has been done to investigate the impact of temperature, tilt and azimuth angles, and ground reflectance on the performance of solar energy system. HOMER software was used as a tool in this study where Choman, Iraq, was selected as a case study. The results indicate that with a base case (temperature coefficient of − 0.48%/ °C, albedo of 20% and ambient temperature of 11 °C), facing the PV to south with a tilt angle of 40° or 45° results in the most economical system by having net present cost of $70595 and cost of energy of $0.54/kWh. Furthermore, PV modules with high sensitivity to temperature are found to be an attractive option based on Choman ambient temperature. Meanwhile, increasing the ground reflectance from 10 to 90% results in an increase of the annual optimum tilt angle from 38° to 52° and a decrease of the PV required capacity from 20.8 to 19.4 kW (for temperature coefficient of − 0.48%/ °C). The results prove that the studied parameters must be treated well to establish an enabling environment for PV development in Iraq.

Photovoltaic (PV) technology has become increasingly an important source of energy. In PV systems, the inverter is a crucial device. Hence, it can be employed in different structures to build the PV plant and to improve the system performance. In this paper, the minimum Levelized cost of electricity (LCOE) is computed by the proposed optimization procedure for comparison purpose between the most used topologies for PV plants, central and string structures. Two cases with a nominal power limit of 100 kWp and, no power limit using all PV plant area are considered. As a result, PV plant using central layout presents the lowest LCOE with limited nominal power and with no limit compared to string mode. Additionally, the sensitivity analysis proves that by increasing the inverter efficiency, the PV plant LCOE decreases.

Iraq has massive potential for electricity generation from solar energy. Because the country currently suffers from daily electricity shortages, a grid-connected PV system is an unsuitable option since the PV cannot serve the load during the electricity blackouts. This paper aims to analyze the techno-economic and environmental feasibility of a solar PV microgrid system which is able to supply the load during both grid availability and outage periods. A household in Baghdad was selected as a case study. HOMER software was used to carry out the overall analysis using five different control strategies. The results indicated that the most economical configuration was achieved by allowing the grid to charge the batteries at all rates, with a net present cost (NPC) of $29,713. A sustainability assessment revealed that preventing the grid from charging the battery resulted in the highest renewable fraction and the lowest CO2 emissions with 64.9% and 4,533 kg/year, respectively. Furthermore, inserting a diesel generator to an economically optimized system was found to reduce the NPC by 11.6%, while increasing the CO2 emissions by 32.7%. This study showed that implementing this sort of project can provide clean, economical, and continuous electricity production in countries with daily blackouts.

At present, photovoltaic (PV) power plants are growing rapidly to respond to the high demand for energy. In this case, improving the levelized cost of electricity (LCOE) and produced energy for PV power plants is a complicated design tradeoff that involves several parameters, such as meteorological data variation, nonlinear operation of the PV plant components, inverter types, and PV module efficiency. Hence, this study intended to present the application of recent meta-heuristic techniques, namely, salp swarm algorithm (SSA), whale optimization algorithm (WOA), and grey wolf optimization (GWO), for two different cases. The technology of crystalline silicon (c-Si) and thin-film cadmium telluride (CdTe) PV modules is adopted for economic considerations and to determine the suitable PV module for the PV power plant. The optimization process is considered to minimize the LCOE and suggest the optimal sizing of PV modules and inverters on the basis of several candidates and their arrangement within the available area with optimal PV module tilt angle and orientation, as well as the optimal distribution of PV modules among the inverters. The new approaches have been compared with particle swarm optimization (PSO) algorithm. The proposed technique (GWO) shows significant results compared with other methods (PSO) in solving the optimal design of the PV power plant. The PV plant LCOE using thin-film (CdTe) has the lowest value compared to crystalline silicon (c-Si). The PV module efficiency and technology affect the overall dimension of the PV power plant.

Off-grid hybrid energy systems (HESs) have become more cost-effective and reliable than single-source systems for the electrification of rural areas. This paper presents a techno-economic and environmental analysis of different hybrid systems to supply electricity to a typical Iraqi rural village. The HOMER software is utilized for the optimization of the systems using the multi-year module, which has been overlooked in the literature thus far. The analysis shows that the PV/hydro/diesel/battery HES is the most economical option with a net present cost (NPC) of $113201, in addition to having acceptable technical and environmental performance levels. Throughout the project’s 20 year lifetime, PV electricity production is reduced by 9.1% while diesel electricity production, CO2 emissions and served load are increased by 90.8%, 91.7% and 8.8%, respectively. The NPC for the multi-year module shows an increment of 22.5% in comparison with that of the single year module. Furthermore, the sensitivity analysis of some rarely reported parameters, such as water pipe losses, generator minimum load, battery roundtrip efficiency, battery setpoint state of charge, capacity shortage, PV capital cost multiplier and multi-year, demonstrated that variations in these parameters have significant effects on the system power flow and its economic analysis.

In recent years, the concept of hybrid energy systems (HESs) is drawing more attention for electrification of isolated or energy-deficient areas. When optimally designed, HESs prove to be more reliable and economical than single energy source systems. This study examines the feasibility of a combined dispatch (CD) control strategy for a photovoltaic (PV)/diesel/battery HES by combining the load following (LF) strategy and cycle charging (CC) strategy. HOMER software is used as a tool for optimization analysis by investigating the techno-economic and environmental performance of the proposed system under the LF strategy, CC strategy, and combined dispatch CD strategy. The simulation results reveal that the CD strategy has a net present cost (NPC) and cost of energy (COE) values of $110,191 and $0.21/kWh, which are 20.6% and 4.8% lower than those of systems utilizing the LF and CC strategies, respectively. From an environmental point of view, the CD strategy also offers the best performance, with CO2 emissions of 27,678 kg/year. Moreover, the results show that variations in critical parameters, such as battery minimum state of charge, time step, solar radiation, diesel price, and load growth, exert considerable effects on the performance of the proposed system.

One of the most important parameters in order to obtain maximum solar radiation for solar power system is the optimum tilt angle of photovoltaic (PV) panels. In this article, the optimum tilt angles of photovoltaic panels are determined for regions of different climatic zones. The annual maximum energy output of PV panels is calculated in MATLAB considering irradiance data only. Annual, seasonal and monthly optimum tilt angles of PV arrays of approximately same latitude with different climatic zones are calculated for fixed tilt angles on the basis of maximum energy output. The incident global solar radiation on the horizontal surface is separated to its direct and diffuse components with a solar angle based mathematical model. Depending on region’s latitudes, direct and diffuse radiation, and tilt angle of PV panels, the incident global radiation on inclined surface is calculated for USA conditions. This study is conducted for seven different regions with very close latitudes but different climate zones. It is clear from the result that PV panels with fixed tilt angles located in approximately-same latitudes may result in different optimum tilt angle due to the dissimilar climatic impacts.

The solar photovoltaic (SPV) panel cell's temperature is the main parameter that gives significant effect on the conversion efficiency of SPV panel. In the present work, simple and efficient front water spraying cooling system in a photovoltaic panel has been designed and developed to introduce active cooling in order to eliminate heat. The performance of the proposed cooling system has been tested and evaluated for the weather climate of a city in Jitra Kedah, Malaysia. The experimental result revealed that with front water cooling system the cell temperature measured at the back of the solar panel can be significantly reduced up to 20-22 °C. Consequently the electrical efficiency of the SPV panel improves by 10.5% with the introduction of the proposed cooling technique.

The depletion of conventional energy sources and global warming has raised worldwide awareness on the usage of renewable energy sources particularly solar photovoltaic (PV). Renewable energy sources are non-polluting sources which can meet energy demands without causing any environmental issues. For standalone PV systems, a low conversion efficiency of the solar panel and high installation cost due to storage elements are the two primary constraints that limit the widespread use of this system. As the size of the system increases, the demand for a highly efficient tracking and charging system is very crucial. Direct charging of battery with PV module will results in loss of capacity or premature battery degradation. Furthermore, most of the available energy generated by the PV module or array will be wasted if proper tracking technique is not employed. As a result, more PV panels need to be installed to provide the same output power capacity. This paper presents selection, design and simulation of maximum power point tracker (MPPT) and battery charge controller for standalone Photovoltaic (PV) system. Contributions are made in several aspects of the whole system, including selection of suitable converter, converter design, system simulation, and MPPT algorithm. The proposed system utilizes direct duty cycle technique thus simplifying its control structure. MPPT algorithm based on scanning approach has been applied by sweeping the duty cycle throughout the I-V curve to ensure continuous tracking of the maximum power irrespective of any environmental circumstances. For energy storage, lead acid battery is employed in this work. MATLAB/Simulink® was utilized for simulation studies. Results show that the propose strategy can track the MPPs and charge the battery effectively.

Photovoltaic (PV) cells can produce electrical energy from irradiance; however besides than electrical energy transformation, the remainder energy can also be transformed into thermal energy which increases the temperature of PV cell. The high operating temperature in PV cell will affect the electrical power output and PV cell lifespan. Numbers of researchers had designed different Photovoltaic/Thermal (PV/T) collector for cooling with better electrical and thermal efficiency. This paper presents a review of literature available that cover different configuration and design of water Photovoltaic/Thermal (PV/T) and their performances in terms of electrical efficiency. The review covers detailed previous researchers work of experimental design and the evaluation of the electrical efficiency. It can be concluded that, the performance of PV/T system depends on the factor of different cooling methods of passive and active, type and size of the cell, and climatic factors such as solar radiation and ambient temperature.
