“…Where I rr is the annual average daily irradiation of the geographical location and is the total efficiency of the PV system. By considering the PV panels reduction factor and the efficiencies of the cables, the controller, the battery, and the inverter, the total system efficiency is found to be 60% [10]. With an annual average daily irradiation of 6.34 kwh/m .day (average value of the four studied stations), a required power of 27.24 kW p is deduced for the PV generation system.…”

Proper combination of wind and solar photovoltaic (PV) systems can result in optimal configurations that maximise the Annual Energy Production (AEP) while being economically attractive. This paper presents a typical approach to the design of a hybrid PV-Wind system for household applications in rural areas. Based on the capacity factor of the hybrid system components, a design methodology was developed to maximize the AEP and to minimise the investment cost. The electricity generated will be used to meet the load requirements of the user while the potential excess of the power will be stored in the battery system or dissipated in a dump resistor. This design methodology is suitable for household applications presenting limitations in the available roof area where the PV panels will be installed. Implementing the PV panels on the house's roof intends to eliminate the shadow over the panels, to avoid the material damage, and to prevent vandalism. Four different cities were selected to conduct the study. These are Tetouan, Essaouira, Dakhla, and Ouarzazate. For the present design approach, the installed cost of the hybrid system includes the price of the storage system.

This paper elucidates the concept of a solar-powered automatic fertilizer system, where the farmers are able to control the injection of fertilizer intake with the intention of tackling the overdose fertilizer intake and electricity accessibility issues. The main objectives of this paper are to design a photovoltaic (PV) system for automatic fertilizer system by considering the total of 300 chili crops, to develop an algorithm that can automatically agitate a proper proportion of fertilizer and to design a prototype for the development of the solar-powered automatic fertilizer system in chili fertigation technology. Arduino UNO is selected as the microcontroller to program the system while sensors such as EC sensor, ultrasonic sensor and flow rate sensor are used to initiate the agitation of fertilizer A, fertilizer B and water into the mixer tank. The system has been built accordingly and the performance of the system is tested. As a consequence, the result shows that the system is able to run with the aid of solar energy and the overall concept of the system can be implemented for the real application of the fertigation system.

“…From the conducted survey and through personal communications with local energy specialists, the encountered problems are very likely to affect the majority of the SHSs installations [17]. A study in Tanzania showed how inefficient loads and ignoring load demand estimation are common mistakes that lead to SHSs failure [18]. Moreover, the lack of solar power systems knowledge as a factor for SHSs failures has been investigated in a previous study conducted by Azimoh et al in South Africa [19].…”

Solar home systems (SHSs) represent a viable technical solution for providing electricity to households and improving standard of living conditions in areas not reached by the national grid or local grids. For this reason, several rural electrification programmes in developing countries, including Namibia, have been relying on SHSs to electrify rural off-grid communities. However, the limited technical know-how of service providers, often resulting in over-or under-sized SHSs, is an issue that has to be solved to avoid dissatisfaction of SHSs´ users. The solution presented here is to develop an open-source software that service providers can use to optimally design SHSs components based on the specific electricity requirements of the end-user. The aim of this study is to develop and validate an optimization model written in MS Excel-VBA which calculates the optimal SHSs components capacities guaranteeing the minimum costs and the maximum system reliability. The results obtained with the developed tool showed good agreement with a commercial software and a computational code used in research activities. When applying the developed optimization tool to existing systems, the results identified that several components were incorrectly sized. The tool has thus the potentials of improving future SHSs installations, contributing to increasing satisfaction of end-users.
