Sunceco SEP 355 HC 355W Polycrystalline Solar Panel
Model SEP 355 HC | Polycrystalline | 144 Cells | Monofacial | 1500V System Voltage
Product Overview
The Sunceco SEP 355 HC is a reliable 355W polycrystalline solar panel built for strong everyday energy production. It combines a 144-cell layout with a compact monofacial design for dependable performance in residential and commercial installations. The module delivers an efficiency rating of 17.6%, with positive power tolerance and stable output under standard operating conditions. Its tempered glass, anodized aluminum frame, and IP68 junction box support long-term durability. This model is backed by a 15-year product warranty and a 25-year performance warranty, making it a practical choice for buyers seeking consistent solar generation and long service life.
Key Benefits
Strong power output: The module produces up to 355Wp for dependable daily generation.
Efficient energy conversion: Its 17.6% module efficiency helps maximize usable roof space.
Positive power tolerance: A 0 to +5W tolerance supports reliable nameplate performance.
Built for harsh conditions: It is designed to resist sand, dust abrasion, salt mist, ammonia corrosion, and fire risk.
Long-lasting durability: The module is tested for wind, snow, hail, and triple EL quality checks.
How It Works
The SEP 355 HC converts sunlight into electricity through polycrystalline silicon cells arranged in a 144-cell module. Sunlight strikes the cells, and the photovoltaic process generates direct current for solar energy systems. The panel’s electrical design supports steady output under standard test conditions and in normal operating environments. Its low temperature coefficients help maintain performance when temperatures rise. The module is also engineered to handle low irradiance more effectively, which supports energy production during weaker sunlight. Durable construction materials and sealed components help the panel continue working reliably over many years.
Photovoltaic conversion: The polycrystalline cells absorb sunlight and convert it into usable electrical energy. This process begins immediately when light reaches the module surface.
Bypass diode protection: Three bypass diodes help reduce performance loss from partial shading. They also support more stable operation across the module string.
Weather-resistant design: Tempered glass, IP68 protection, and an anodized aluminum frame protect the module in demanding environments. These features improve long-term durability and system confidence.
