Saana - Model 245-255 M3 MBB - Monocrystalline Solar Module 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 high transmission structured glass has a light texture on the front and a deeper texture inside, which improves the adhesion of the EVA encapsulant. This combination of textures also gives improvement to the performance of the solar module compared to smooth glass.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”E??????????? ????????????? ????? ??????????????? ????? ?????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 light textured surface of the matt glass improves the performance of the module• The deep texture inside of the glass improves the adhesion of the EVA encapsulant• 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 245-255 M3 MBBSaana 245-255 M3 MBBNaps Systems Ltd • Ruosilankuja 4, FI-00390 Helsinki, Finland Tel. +358 20 7545 666 • sales@napssystems.com • www.napssystems.comMade in EU??????????????????????????????????????????????? ??????????? ???????????????????? ?????????????? ­??????????? ?????????????????????????????????? ­?????????????­Specifications may change without notice due to Naps’ policy of continuous product development.
