Product Description

Polycrystalline silicon solar photovoltaic panels are PV modules built around polycrystalline silicon cells. Polycrystalline silicon is cut from cast multicrystalline silicon ingots, featuring a distinctive ice-blue crystalline pattern on the surface with high recognizability. Its photoelectric conversion efficiency typically ranges from 14.4% to 17.2%. Although slightly lower than monocrystalline modules, polycrystalline modules retain a significant economic advantage in price-sensitive applications thanks to lower manufacturing costs and mature mass-production processes, with a cost per watt approximately 65%~75% that of monocrystalline modules.

The module adopts a multi-layer structural design: the surface layer is 3.2mm ultra-white textured tempered glass with over 91% light transmittance; the middle layer bonds the cell array with EVA film; the backsheet uses corrosion-resistant TPT composite material; and the frame is made of high-strength anodized aluminum alloy. The module can withstand 2400Pa wind load and 5400Pa snow load, with an operating temperature range of -40°C to +85°C, offering hail impact resistance and sandstorm durability.

Polycrystalline modules are available in power ranges from 5W to 340W, covering 36-cell, 60-cell, and 72-cell configurations. They are widely used in off-grid power systems, solar street lights, traffic signals, communication base stations, agricultural PV greenhouses, and village-level poverty alleviation power stations, with a service life of 20~25 years, making them a rational choice for budget-limited scenarios with ample installation area.

Application Scenarios

Off-Grid & Distributed Power Generation — Suitable for military and civilian electricity needs in remote areas such as plateaus, islands, pastoral areas, and border outposts, as well as distributed generation and off-grid power stations

Transportation & Municipal Facilities — Autonomous power supply for unattended outdoor facilities including navigation lights, traffic signal lights, warning signs, high-altitude obstacle lights, and smart street lights along highways, railways, and waterways

Solar Lighting Systems — Power supply for garden lights, street lights, lawn lights, portable lights, camping lights, and other solar lighting equipment

Communication & Monitoring Equipment — Power supply for microwave relay stations, forest fire monitoring, highway surveillance, hydrological and meteorological observation, and pipeline cathodic protection

Large-Scale Ground-Mounted Plants & Agricultural PV — Large ground-mounted PV power stations, agricultural PV greenhouses, village-level poverty alleviation power stations, school rooftops, and breeding shed roofs where space utilization requirements are not high

Residential & Commercial Systems — Household rooftop PV systems, commercial PV systems, and building-integrated photovoltaics (BIPV)
