FAQ
Solar panels convert sunlight into electricity through the photovoltaic effect:
Made of silicon cells (monocrystalline or polycrystalline)
Sunlight excites electrons, creating direct current (DC) electricity
Inverters convert DC to alternating current (AC) for home/industrial use
Works even on cloudy days (though at reduced efficiency)
JA Solar provides:
Product Warranty: 12-year material and workmanship warranty
Performance Warranty:
25 years at ≥ 84.8% of nominal power output
Linear degradation guarantee (e.g., ≤ 2% in the first year, ≤ 0.55% annually thereafter)
Key performance factors include:
Sunlight intensity and duration (peak sun hours)
Temperature (performance decreases slightly in extreme heat)
Shading from trees or buildings
Panel orientation and tilt angle
Dust/dirt accumulation (regular cleaning recommended)
Module quality and technology (e.g., PERC, TOPCon cells)
Most quality panels lose about 0.5-0.7% efficiency per year.
