Optimization of Solar Panel Angle Based on Real-time Tracking in Indian Cities

Abstract

This study discusses angle optimization for Indian solar panels through real-time tracking systems, considering photovoltaic efficiency. Static panels with a fixed tilt never realize complete sunlight due to the different climatic zones and irradiance in India. Hence, representative cities were selected: Delhi, Mumbai, and Bengaluru, to receive weather and geographic conditions differently. Solar irradiance, geographic, and meteorological data were recorded and given as input to mathematical models and simulation software to output angles optimized on a dynamic basis to match the sun’s trajectory. While comparative analysis indicated a gain in performance with both fixed-angle and tracking systems, maximum improvement was recorded in cities where sunlight levels vary, while even cloud-laden places saw reproached and slight efficiency gains. Several enhancements were witnessed in energy yield despite extra cost and maintenance issues. The study thus affirmed the viability of real-time tracking for achieving India’s renewable energy goals and suggested that further research could be directed toward reducing cost, improving design life, and integrating tracking into smart grid systems for sustainable solar deployment.
