Special Issue Information
Dear Colleagues,
The development of renewable energy technology is now widely considered of paramount importance to moving towards sustainable energy generation and climate change mitigation. The low-energy density and seasonal variations, with geographical dependence, make the development of high-solar-energy concentration systems an important and challenging investigation. Advances in solar collectors and solar energy concentration enable not only a massive scaling in energy production but also can lead to industrial decarbonisation. The efficiency of solar collectors and other solar energy concentration systems is significantly affected by errors in their alignment with the Sun. Thus, the necessity and the importance of solar tracking systems become a critical key for the development and implementation of any photovoltaic system or solar collector.
This Special Issue is intended to collect original research works, reviews and case studies on innovative technology developments to maximize the collection efficiency of different energy generation systems. The topics of interest for publication include, but are not limited to, the following:
- New progresses in solar collectors to maximize the collection efficiency of different energy generation systems.
- Advancements in the solar collection and concentration efficiency.
- PV technology/solar collectors and their potential applications for a low-carbon industry.
- Improved solar tracking for energy-production systems.
- Developments in solar cells for PV technology.
- Solar-pumped lasers.
- Solar energy collectors for hydrogen production.
- Integrated operation of solar collectors, energy storage and potential industrial applications.

Title: Design and implementation of microcontroller-based solar charge controller using modified incremental conductance MPPT algorithm
Authors: Mustafa Sacid Endiz
Affiliation: Necmettin Erbakan University, Engineering Faculty
Abstract: This paper presents the modeling, design, and implementation of a rapid prototyping low-power solar charge controller with maximum power point tracking (MPPT). The implemented circuit consists of a 60 W photovoltaic (PV) module, a buck converter with an MPPT controller, and a 13.5V-48Ah battery. The performance of the solar charge controller is increased by operating the PV module at the maximum power point (MPP) using a modified incremental conductance (IC) MPPT algorithm. While the traditional IC MPPT approach requires a substantial amount of code and algorithmic steps to keep the PV module at the MPP, the proposed IC achieves the same process with a reduced number of lines of code, owing to its optimized algorithmic approach. By adjusting the duty cycle of the generated Pulse Width Modulation (PWM) signal, maximum power transfer from the PV module is attained during the operation of the battery charging process. The simulation model is configured and tested in Matlab/Simulink environment under different solar data (1000 W/m2, 500 W/m2, 800 W/m2) with constant temperature (25 °C). To validate the simulations, experimental studies are conducted using the developed rapid prototype with the 32-bit embedded microcontroller in the laboratory. According to the obtained results, the proposed IC tracks the MPP more accurately with less steady-state oscillation and provides maximum available power with 98.6% average tracking efficiency for battery charging at different solar radiations compared to the traditional IC approach. For low-powered electric devices, the proposed system can be used to provide a charging infrastructure solution.
Title: A rapid prototyping low power charging unit for Modified GWO-MPPT using ANFIS

Abstract: The increasing need for energy, coupled with progress in technology has emphasized the importance of renewable energy sources around the world. Solar energy systems harness the power of sunlight to generate electricity, offering a renewable and environmentally friendly alternative to conventional energy sources. Maximum Power Point Tracking (MPPT) algorithms are employed to achieve optimal efficiency from the PV systems. This paper introduces a new method for controlling Maximum Power Point (MPP) in battery charging systems using an improved Grey Wolf Optimization (IGWO) algorithm.The study includes the fast-changing climatic conditions and evaluation of IGWO, which can update itself with Adaptive neuro-fuzzy inference system (ANFIS). An analysis was performed to evaluate the behavior of the system in the laboratory environment using rapid prototyping. The proposed IGWO algorithm demonstrates an improved accuracy when compared to traditional methods in the current literature. The study aims to enhance the efficiency of MPPT control in photovoltaic (PV) systems, offering a potential solution for optimizing performance in different environmental conditions.
