Import 315w Monocrystalline Perc Solar Panel — Buy in wholesale FOB from Supplier in China

The 315W monocrystalline PERC solar panel from Xi'an Runda Resource Technology Co., Ltd. uses passivated emitter and rear cell (PERC) architecture with 120 half-cut mono-crystalline cells of 156.75 x 78.38 mm format, delivering a module efficiency of 18.96 percent under standard test conditions. At STC (1000 W/m2 irradiance, AM 1.5 spectrum, 25 degrees Celsius cell temperature), electrical parameters include 33.1 V optimum operating voltage (Vmp), 9.52 A optimum operating current (Imp), 39.9 V open-circuit voltage (Voc), and 10.06 A short-circuit current (Isc). Nominal module operating temperature (NMOT) data at 800 W/m2, 20 degrees Celsius ambient, and 1 m/s wind speed yields 235 W Pmax, 30.7 V Vmp, 7.65 A Imp, 37.5 V Voc, and 8.11 A Isc, providing realistic performance expectations for temperate climate installations.

The module employs 2.5 mm heat-strengthened glass on front and back in a frameless or framed configuration, with overall dimensions of 1675 x 992 x 5.8 mm without junction box and corner protector, or 1678 x 995 x 8.5 mm with corner protector but without junction box. The 24 kg module accommodates 1500 V IEC or 1000 V IEC/UL maximum system voltage, with 30 A maximum series fuse rating and Class A application classification per IEC 61730. Operating temperature range spans -40 degrees Celsius to +85 degrees Celsius, with power tolerance of 0 to +5 W ensuring no negative deviation from nameplate rating. Cell arrangement follows 2 x (10 x 6) configuration, with half-cut cell design reducing resistive losses and improving shade tolerance compared to full-cell modules.

This panel suits utility-scale ground-mount, commercial rooftop, and industrial distributed generation projects where high voltage string design reduces balance-of-system costs. EPCs and project developers targeting markets with 1500 V IEC system approval benefit from reduced string count and associated hardware. When sourcing from Xi'an Runda Resource Technology Co., Ltd., confirm whether the 315W variant is stocked or produced to order, the specific frame option (framed or frameless), junction box and connector type, and whether IEC 61215/IEC 61730 certification test reports and factory inspection records are available for your market's regulatory requirements.

Xi'an Runda Resource Technology Co., Ltd. is headquartered at No.38 Jinye Road, Xi'an, Shaanxi Province, China, a location inland from China's eastern coastal manufacturing belt that may influence logistics options and lead times for export orders. The company holds a 'harbor' trust tier with zero percent response rate and zero average response hours recorded on the platform, suggesting that buyers should anticipate delayed communication and plan procurement timelines with additional buffer. The listing presents the company as offering Kudymond-branded high-efficiency mono PERC modules in the Cs3k series, with power ratings from 300W to 315W, though the exact relationship between Xi'an Runda and the Kudymond brand (licensor, manufacturer, distributor) is not clarified in the source data. No factory certification, production capacity, annual revenue, or employee count is disclosed, requiring direct verification of manufacturing credentials and quality system scope.

The supplier's product description provides detailed electrical and mechanical data for the Cs3k-315MS-FG variant, including both STC and NMOT performance parameters, which indicates technical familiarity with module specification at the listing level. However, the absence of information on warranty terms (typically 10-12 year product and 25-30 year linear power warranty for this product class), degradation rate guarantees, or whether the modules are listed in international databases such as PV InfoLink, Bloomberg NEF, or on the IEC CB scheme limits immediate qualification for selling points. Buyers should request clarification on whether Xi'an Runda manufactures the cells and modules, or sources cells for module assembly, as this affects supply chain transparency and technology control. For project finance or utility procurement, evidence of bankability, third-party factory audits, and insurance-backed performance guarantees would need to be established through direct negotiation.
