Monocrystalline photovoltaic panel GWL/Sunny-450MPH with peak power of 450Wp excels with unified white design (frame, covered busbars, cells). The panel offers excellent power output throughout the complete sun spectrum, its durable frame, and structure is capable of holding heavy snow load up to 5400 Pa and Wind load up to 2400 Pa. The panel is resistant to salt mist, ammonia, and blowing sand and therefore suitable for seaside, farm, or desert areas. The junction box is enclosed in the IP67 protective casing increasing its long term weather resistance.

Power output characteristics - temperature and irradiance

Solar panels are fed by direct Sunlight, however, they perform better in colder ambient temperatures. All Datasheet values are measured under standardized 25°C. The graf shows the behavior of the panel in warmer areas. Panel losses part of its output efficiency, but is well suited even for extremely hot areas.

Panel behaviour under different Temperature

Like with temperature, the Datasheet values are stated at standardtized value of irradiance at 1000 W/m2, to roughly calculate actual power output in your area, find the avarage irradiance and compare with the graf.
