Naps - Model 245-255 TP3 MBW - Solar Modules Brochure

Naps Systems’ 30 years of solar power experience in all continents and conditions provide the highest level of quality and power in an attractive and dependable package.High power and efficiencyNaps Saana series of solar modules contain 60 high efficiency, almost black semisquare monocrystalline solar cells. The cells are carefully selected to assure a narrow and positive power range, thus minimising mismatch losses in the system.The deeply textured surface of the prism glass improves light transmission to the solar cells. An increase of up to 3% is attained in the rated maximum power under Standard Test Conditions. At low sun elevation, the transmitted light is increased by up to 20%. In a typical grid-connected system in Germany and similar locations, the annual energy production is increased by approximately 5% compared to smooth glass modules of the same power rating.Dependable construction and long lifeFeaturing the highest standards of construction and materials, Naps Saana solar modules are able to withstand the harshest environments and continue to perform efficiently. Properly installed, these modules have a design life well beyond the power warranty. Limited power warranties are given for both 10 and 25 years. The modules are tested to meet or exceed all relevant international standards and the highest requirements for quality and performance. 69º02’37”N Saana 20º51’22”O??????????? ????????????? ????? ???????????????? ????? ?????www.napssystems.com• Carefully selected semisquare monocrystalline silicon solar cells for close tolerance• Solar cells treated for reduced reflection and for efficient conversion of both direct and diffuse light• Electrical circuit laminated between layers of ethylene vinyl acetate (EVA) for electrical isolation, moisture resistance and UV stability• Low iron content, tempered glass for mechanical protection and high light transmission• The textured surface of the prism glass improves standard rated power by up to 3% and increases the current by up to 20% at low sun elevation• Multi-layered polymer backsheet for resistance to abrasion, tears and punctures and dependable electrical insulation• Rugged and lightweight anodised aluminium frame with mounting, grounding and drainage holes• Junction box with pre-fitted cables and quick connectors designed for ease and safety• Wired-in bypass diodes to reduce potential loss of power and damage from partial array shading• Tested for a wide range of operating conditions (-40°C to +85°C)• Tested to withstand the highest wind, hail storm and snow load requirements (5400 N/m2)• Designed to meet or exceed the environmental requirements of IEC61215• Designed to meet the requirements of IEC61730, including Safety Class II to IEC61140Naps Saana 240-250 SM3 PBBSaana 240-250 SM3 PBBSpecifications may change without notice due to Naps’ policy of continuous product development.
