Sunceco SEP 350 HC 350W Polycrystalline Solar Panel
Model SEP 350 HC | Polycrystalline | 144 Cells | Monocrystalline? | 1500V System Voltage
Product Overview
The Sunceco SEP 350 HC is a polycrystalline solar panel designed for dependable daily energy generation. It combines a 350 Wp output with a 144-cell layout and a compact 35 mm frame. The module is built for strong real-world performance, with positive power tolerance and reliable output in low-irradiance conditions. Its tempered glass, anodized aluminum frame, and IP68 junction box support long-term durability. With a 15-year product warranty and a 25-year performance warranty, it is positioned for stable residential or commercial solar use. The panel’s 17.4% efficiency helps maximize energy yield while maintaining practical installation dimensions. This model is supplied by Sunceco Inc. in the United States.
Key Benefits
Strong power output: The module delivers up to 350 Wp, helping improve system yield in limited roof space.
Reliable efficiency: A 17.4% module efficiency supports steady energy production across demanding installations.
Durable construction: Tempered glass, anodized aluminum, and IP68 protection improve long-term outdoor resilience.
Positive power tolerance: A 0 to +1.5% tolerance supports reliable delivered performance from the installed module.
Low-irradiance performance: The panel is engineered to maintain useful output when sunlight levels are reduced.
How It Works
The SEP 350 HC converts sunlight into usable electricity through polycrystalline silicon cells arranged in a 144-cell format. Each cell generates direct current when exposed to sunlight. The internal cell layout supports stable voltage and current delivery for solar system design. A low temperature coefficient helps limit performance losses in hot weather. The panel also benefits from bypass diodes, which help reduce output loss during partial shading. These design features work together to improve energy harvest across varied installation environments. The module is built to perform consistently in standard test conditions and under nominal operating temperatures. Its structure is intended to support safe, dependable, and efficient solar power generation.
Cell conversion: The polycrystalline cells absorb sunlight and convert it into electrical energy. The 144-cell configuration helps balance voltage and power delivery.
Bypass protection: Three bypass diodes help reduce the impact of shading. This supports steadier output in less-than-ideal conditions.
Thermal behavior: The temperature coefficients show how output changes with heat. This helps installers estimate performance in warm climates.
