Solar Charge Controllers and their Implementation
Abstract: AbstractSolar energy is the incident energy from the Sun. The main components of this energy are incident light energy and the heat contained in it. The extraction of solar energy may be active or passive. Due to abundance and availability, solar energy is the most attractive alternate in available renewable resources. In the 21st century solar energy is expected to become increasingly attractive as a renewable energy source because of …

Advancing Grid Integration: Maximum Power Point Tracking-Based Model Predictive Current Control Technique for Photovoltaic Systems
Abstract: Tracking a PV system's maximum power point is necessary as demand for grid-connected solar systems rises, regardless of utility demand. Since the PV system's output is D.C., a converter serving as a middleman between the PV system and the D.C. link capacitor is necessary to track the maximum power at all loads. Since the firing angle of the IGBT in the boost converter is between 0 and 1 at maximum …

Construction and Comparative Analysis of Passive and Active Indirect Hybrid Solar Dryer’s for Drying Tomatoes
Abstract: The surplus agricultural products needed to be preserved by drying during harvesting period for long term storage. The application of modern techniques of solar thermal systems using solar dryers substitutes the use of an olden day’s method of direct sun radiation. This research entailed construction and comparative performances analysis of two different hybrid indirect solar dryers. The average daily air flow rates and temperatures in the dryer’s chamber, the weight …

Development and Performance Evaluation of GO–ZnO/PU Hybrid Nanocomposite Coatings for Improved Optical Transmission, Cooling, and Self-Cleaning in PV Systems
Abstract: The performance of solar photovoltaic (PV) modules with time is affected by thermal heating, dust buildup, and exposure to ultraviolet (UV) light; as a result, the power loss increases rapidly during the use condition. In this study, a polyurethane (PU) nanocomposite, fabricated with graphene oxide and zinc oxide (GO–ZnO), is invented and examined. Improvements in heat management, light transmission, and dirt resistance are planned for PV glass surfaces. The nanocomposite …
