Polycrystalline photovoltaic panel EXS-290P-S with peak power of 290Wp excels with unified 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 3600 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 IP68 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.
Like with temperature, the Datasheet values are stated at standardtized value of irradiance at 800 W/m2, to roughly calculate actual power output in your area, find the avarage irradiance and compare with the graf.
30 years Warranty
The manufacturer provides up to 30-year Warranty for remaining Power output. The warranty is calculated linearly year by year.
The warranty in detail:
The long warranty period is possible by quality inspection and testing during production. The manufacturer hosts testing laboratory used to confirm CE, JET, TUV, CULSA, MCS, OHSAS and ISO certifications. They also use this laboratory to ensure their product meet the highest standards.
