  • Roof 305w Polycrystalline Solar Panel 3% Output Power Tolerance Black Frames - China

    price: check with company for price

    High efficiency 305W photovoltaic polycrystallinesolar panel / 300W305W 310W 315W solar PV module for solar home system. Solar energy products are a trend and good way to achieve zero home bills or commercial invest in the future. So choose a good solar panel is important.The key factors to consider when comparing solar panels are performance (they should produce the power that the rating leads you to expect), quality, durability and beneficial warranty terms. 300W 305W 310W Poly Solar Panel Characteristics 1) high reliability with guaranteed +/-3% output power tolerance 2) The modules can withstand high wind-pressure, snow loads and extreme temperatures 3) Bypass diodes to minimize power loss with shading 4) High and stable conversion efficiency to ensure the highest quality A Grade Polycrystalline Silicon Solar Cell 1) Fomat:1560.5mm, diagonal 2001.0mm 2) Average thickness: 195m 20m 3) Front(-): 1.5mm bus bars(silver) Blue anti-reflecting coating(silicon nitride) 4) Back(+): 2.5mm wide soldering pads(silver) Back surface field(aluminum) Quality and Warranty For a period of twentyfive (25)years commencing on the Warranty Start Date, loss of power output of the nominal power output measured at Standard Test Conditions (STC) for the Product(s) shall not exceed: For Polycrystalline A grade solar cell, 3% in the first year, thereafter 0.66% per year, ending with 81% in the 25 th year after the Warranty Start Date; The Warranty Start Date shall be defined as the date of the Bill of Lading date 10Years Manufacturing Warranty 15Years Warranty 90% Power Output 25Years Warranty 85% Power Output Specifications: - - - - Solar Panel Parameters | KL-305W-P | Optimized working voltage | 36.00V | Optimized working current | 8.472A | Open circuit voltage | 43.2V | Short circuit current | 7.06A | Nominal power | 305W | Operating temperature | -40 to+85 | Maximum system voltage | 1000VDC(IEC)/600VDC(UL) | Series fuse rated value | 20A | Power tolerance | 3% | Cell specification | 156156mm (6inch) | Arrangement quantity | 72(612) | Solar panel dimension | 195099050mm | Weight | 27.0kg | Glass specification | 3.2mm(0.13inch) tempered glass | Frame | Anodised aluminium alloy | Rated operating temperature | 452 | Pmax temperature parameter | -(0.480.05)%/ | Voc temperature coefficient: | -(0.340.1)%/ | Isc temperature coefficient | 0.040.01%/ | Notic:Data under standard testing condition (STC):1000W/, AM1.5, 25. | - - - - Glass > Antireflective glass > Translucency of normal luminance is increased by 2% > Module efficiency is increased by 2% > Self-cleaning function > Service life is as long as 25 years (30 years optional) Solar Cell > High Efficiency PV Cells > Appearance Consistency > Color sorting ensure consistent appearance on each module > Anti-PID Frame > Conventional frame > Silver or black frames are optional > Boost bearing capability and prolong service life > Serrated-clip designtensile strength > Seal-lip designglue injection Junction box > Conventional standalone edition and engineering custom edition > Quality diode ensures module running safety > IP67 protection level > Heat dissipation > Long service life EVA anti-aging EVA, excellent weathering resistance TPT Product field: 1.
