Agrivoltaics (Agri-PV, AV) – the joint use of land for the production of agricultural products and energy – has recently been rapidly gaining popularity, as it can significantly increase income per unit of land area. In a broad sense, AV systems can include converters of not only solar, but also energy from any other local renewable source, including bioenergy. Current approach to AV represents an evolutionary development of agroecology and integrated PV power supply to the grid. That results in nearly doubled income per unit area. While AV could provide a basis for revolution in large-scale unmanned precision agriculture and smart farming which is impossible without on-site power supply, chemical fertilisation and pesticides reduction, and yield processing on-site. These approaches could change the logistics and the added value production chain in agriculture dramatically, and so, reduce its carbon footprint. Utilisation of decommissioned solar panels in AV could make the technology twice cheaper and postpone the need for bulk PV recycling. Unlike the mainstream discourse on the topic, this review feature is in focusing on the possibilities for AV to be stronger integrated into agriculture that could also help in relevant legal collisions (considered as neither rather than both components) resolution.

This study evaluates the hydropower potential in the design of a micro-hydro/solar photovoltaic hybrid system with battery energy storage for increasing the access to electricity in Ikukwa Village in Mbeya Region of Tanzania. Usually, hybridized hydropower schemes are designed from perennial streams for the provision of electricity. This study incorporates the run-of-the river (COE) power scheme, which originates from the untapped potential of nonperennial hydro-energy source and the use of traditional approach of data measurements for Ikata tributary to design hybrid system. The system is optimized by the minimization of the total net present cost (NPC) and cost of energy (COE) using the soft computing method of Hybrid Optimization of Multiple Energy Resources (HOMER) software and artificial intelligent (AI) techniques. AI optimization techniques such as particle swarm optimization (PSO), grey wolf optimization (GWO), and GWO-PSO hybrid (GWO-PSOHD) algorithms have been employed for further optimal results. The data for solar radiation and the tributary have been obtained from the National Aeronautics and Space Administration (NASA) and traditional methods of measurements, respectively. The estimated maximum water flow rate and head are 2.943 m3/s and 13 m, respectively. In the same period, the approximated theoretical power potential of the tributary is found to be 375 kW. Total NPCs obtained from HOMER, PSO, GWO, and GWO-PSOHD methods are $ 141, 397.76, $ 95 167.21, $ 92 472.82, and $ 91,854.10, respectively. Similarly, the optimal results of COE from HOMER, PSO, GWO, and GWO-PSOHD approaches are $ 0.1818/kWh, $ 0.1185/kWh, $ 0.1182/kWh, and $ 0.1181/kWh, respectively. Comparatively, PSO implementation has indicated the greatest energy cost, while the cost acquired by GWO-PSOHD is the lowest for all aforementioned AI optimization techniques. The tributary under study has a high potential of diversification of energy sources for rural electrification in the area of study and other parts of the world with comparable conditions.

“…The Charger circuit is Implemented using buck converter with pulse width modulation technique (PWM) to step-down from 44 output voltage of the series connection of two panels to 12 volts matching the voltage of parallel connection of two batteries. When the absorption voltage is reached, the PWM controller employs a transistor as a rapid switch to connect and detach the battery in order to keep the voltage constant and minimize the current to keep the battery safe from damage caused by heating and overcharging [9]. This stage is divided into 2 sub-stages which are authentication methods and charging ports in parallel with 1 sub-stage which is the inverter.…”

Egypt's Vision 2030 revolves around green energy and the facilitation of Egypt's massive unhabituated remote and urban landmass. Such areas lack the infrastructure to support modern life, such as energy grids, so simple things like charging your electronic devices (E-devices) i.e. Mobile phone, laptop, Tablets become a hassle. In this project; by building a mobile green energy source, all beneficiaries will be capable of charging the area's residents' electronics with minimum overhead cost and environmental effect. Leveraging solar panels provides a consistent energy source in a mobile charging station for electronic devices. Due to the nature of such a project no required prior infrastructure, hence ease of applicability. Using two solar cells that convert and store light energy into electric energy in the form of both direct current (DC) and alternating current (AC) are used for charging and running different electrical devices. This station operates under the control of different authentication methods such as face recognition, fingerprint, and Radio Frequency Identification (RFID). Collectively, the three methods aim to control the service for the people meant to get their benefit from it in the needed time. Authors have developed an integrated software system consisting of web and mobile applications. The goal of that system is to help the administrator monitor the charging-station, and the data coming from the hardware system as a whole, receive alerts if something went wrong, and monitor ports usage.
