How Solar Panels Perform in Different Weather Conditions

Solar panels work in various weather conditions, though output varies. Understanding these variations helps set realistic expectations.

**Sunny Days:** - Peak performance (100% capacity) - Best time for energy production - Excess energy charges batteries

**Cloudy Days:** - 10-25% of normal output - Still generates usable energy - More common during rainy season

**Rainy Season:** - Reduced output due to cloud cover - Panels still produce some energy - Increased cleaning needs - Plan for battery backup

**Temperature Effects:** - Panels work better in cooler temperatures - Heat reduces efficiency by 0.4% per degree above 25°C - Ensure proper ventilation under panels - Shade panels during extreme heat

**Harmattan Season:** - Dry winds increase dust accumulation - More frequent cleaning needed - Clear skies increase output - Ideal for solar production

Seasonal Planning:

**Dry Season (Nov-Mar):** - Highest solar output - Excess energy charges batteries - Best time for major loads

**Rainy Season (Apr-Oct):** - Lower output, plan accordingly - Rely more on battery storage - Reduce non-essential loads

**Annual Variation:** Nigeria's tropical location ensures consistent year-round solar potential. Even during rainy season, systems produce 40-60% of dry season levels.
