Many people assume that solar panels only work in sunny weather. However, modern solar technology is designed to generate electricity even on cloudy days, though efficiency is lower.
Understanding how different weather conditions affect your solar panels helps you maintain realistic expectations about your system's performance.
- Weather Impact Overview:
- Sunny Days: 100% efficiency
- Cloudy Days: 25-50% efficiency
- Rainy Days: 15-25% efficiency
- Snow: Minimal to no output
Even in less-than-ideal weather, your solar system continues to generate power. On average, Australian homes can rely on consistent solar generation throughout the year.
Modern inverters and battery storage systems help maximize the use of generated electricity, ensuring your investment delivers consistent returns.
