FAQ Section

Q1: What is the maximum power range for this solar panel series?

A: Our monocrystalline bifacial PV modules cover rated power from 480W,485W,490W,495W up to 500W under STC testing conditions. An extra 25% power gain can be achieved via back‑side light capture.

Q2. Does this panel work well on cloudy or foggy days?

A: Yes. Optimized weak‑illumination cell design guarantees satisfying power output under haze, cloud cover and early‑morning low sunlight.

Q3. Can these panels resist PID power degradation?

A: All units go through strict raw‑material screening and optimized manufacturing procedures for reliable anti‑PID performance.

Q4. What is the operating‑temperature range?

A: Safe working temperature spans ‑40℃ to +85℃, suitable for nearly all global climate zones.

Q5. Is the junction box waterproof?

A: The built‑in junction box reaches IP68 waterproof and dust‑proof rating, fitted with three bypass diodes.
