Yes, PS400 is rated IP68 water-resistant, providing reliable protection against water splashes. However, please avoid exposing it to heavy rain or submerging it in water.

Solar panel output varies with sunlight intensity, panel orientation, and angle. Due to varying conditions, actual power may be lower than rated. For best results, test your panel under full, on obstructed sunlight.

Use a soft cloth to remove dust and dirt from the surface. Then wipe the solar module with a damp cloth to clear any residue, and promptly remove debris of heavy dirt to maintain optimal performance.

Based on our calculations, a 35° tilt optimizes power generation from 10 AM to 5 PM in Japan, the U.S., and Europe. However, the panel's bracket allows slight adjustments if needed.

The black metal frame may heat up after prolonged exposure to sunlight. Avoid touching it directly and wear protective gloves when adjusting or moving the panel to prevent burns.
