A Review on Solar Panel Efficiency Using Dual-Axis Tracking and Efficient Storage in Batteries Using PWM Technology

Solar energy represents a vital renewable resource and sustainable technology, offering significant ecological benefits. It contributes significantly to the achievement of energy solutions for sustainable development. When solar panels are positioned horizontally on the ground, they are unable to fully absorb light but when they are positioned both horizontally and vertically the light can be absorbed to desirable limit by the use of dual axis tracker. For solar panels to be more efficient, an automatic solar tracking system is also necessary. The limitation of the previous mentioned survey is that by the use of off grid solar photovoltaic system the efficiency has been 15.5%. Hence by the use of variable solar tracker to optimize the efficiency of your solar power system where by the use of Dual-axis trackers which can provide even greater efficiency compared to single- axis trackers. This paper reviews a method based on Pulse Width Modulation (PWM) to enhance battery efficiency by the use of monocrystalline solar panel which can provide an efficiency of 45%. This review aims to contribute to the advancement of efficient, sustainable solar energy solutions for broader application in the renewable energy sector.
