In 2025, standard residential solar panels produce between 390-500 watts of power, with high-efficiency models reaching 500+ watts. However, the actual energy output depends on multiple factors including your location, roof orientation, weather conditions, and system design.

Real-world performance expectations: Solar panels typically achieve only 75-85% of their rated capacity under normal conditions due to temperature effects, inverter losses, and varying weather patterns—this is completely normal and not a sign of system failure.
