Products Description 聽 聽 What is a frameless solar panel? 聽 The Frameless solar panel does not have any frame attached to them which results in lower embodied energy and retain its energy efficiency ratings. These frames have solar cells arrayed between two layers of glass and hence also called as glass-on-glass panels or dual glass panel. 聽 聽 聽 What are the disadvantages of transparent solar panels? 聽 鉁盩ransparent solar panels can only produce less amount of power so you will be needing to buy a large set of solar cells to power up entire your house. 鉁盩ransparent solar panels won't be able to power up the existing electronic accessories in your house. 聽 Which of the 3 main types of solar panels are the most efficient? 聽 Among all panel types, crystalline solar panels have the highest efficiency. Monocrystalline panels have an efficiency rating over 20%. PERC panels add an extra 5% efficiency thanks to their passivation layer. Polycrystalline panels hover somewhere between 15-17%. 聽 Bifacial Technology 聽 The power generation gain of the Bifacial Solar Panel mainly comes from the back side, and by receiving the reflected light from the atmosphere and the reflected light on the ground, the overall power generation of the bifacial module is increased. When the sun shines on the Bifacial Solar Panel, some of the light is reflected by the surrounding environment to the back of the panel. This part of the power can be absorbed by the battery, improving panels efficiency. 聽 聽 聽 聽 Standard solar module absorb direct light Bifacial solar module absorb direct light, ground reflected light, spatially scattered light 聽 聽 聽 Double-sided generation, powerfully energy boost: 聽 Fully utilizing the reflection and scattering of light, applying to highly reflective scenes such as water, sand, grass and white painted ground. With various types of brackets, more power is obtained, under lower kilowatt-hour costs. 聽 High reliability: Bifacial modules demonstrate superior long-term reliability, higher quality, and create more value. 聽 Products Data 聽 ModuleBSM380M-72BBSM390M-72BBSM400M-72B Reted Power(Pmpp) (W)380390400 Power Output Tolerance (W)0~+5 Rated Current (lmpp) (A)9.529.729.92 Rated Voltage (Vmpp) (V)39.9240.1340.33 Short Circuit Current (Isc) (A)9.839.949.99 Open Circuit Voltage (Voc) (V)48.6148.8849.08 Efficiency (%)19.419.9220.43 Operational Temperature-40~+85鈩?/p> Maximum Static Load5400Pa Maximum Wind Load2400Pa Maximum System VoltageIEC:1000/1500V Maximum Series Fuse Rating20A 聽 Production Show 聽 聽 Packing & Delivery 聽 Package White angle cover+corrugated case Wood pallet+packaging tapes 聽 Delivery 聽 Few quantity by express(DHL, UPS, FedEx, TNT) Batch order by air or sea(LCL/FCL) 聽 聽 Our Project 聽 聽 Certifications 聽 聽 Our Company 聽 聽 FAQ 聽 Q1: What are your main products?
