What is Solar Panel Efficiency?
Solar panel efficiency refers to how much sunlight hitting the panel gets converted into usable electricity. Modern monocrystalline panels achieve 20-23% efficiency, while polycrystalline panels range from 15-17%.
Factors Affecting Efficiency
Temperature, shading, panel orientation, and dust accumulation all impact real-world performance. India's high solar insolation (about 5000 TWh annually) makes it ideal for solar energy despite temperature challenges.
Choosing the Right Panel
For residential rooftops with limited space, higher efficiency mono PERC panels offer the best kWh per square meter. For ground-mounted commercial installations with ample space, more affordable polycrystalline panels can be cost-effective.
