Model GSPV-315W (156M)66 | Monocrystalline Silicon | 66 Full-Cell 156 x 156 mm | Monofacial | 1000V DC System Voltage
The Green Sun GSPV-315W monocrystalline solar panel delivers reliable 315 watt performance for residential and commercial projects. This GSPV-315W 66-cell module is engineered for stable power output and long service life in demanding environments. A robust aluminum frame, tempered glass, and EVA encapsulation protect each monocrystalline cell from weather and mechanical stress. The panel suits off-grid systems, small rooftop arrays, and distributed projects where dependable output is required. With a maximum system voltage of 1000V DC, the panel integrates smoothly into a wide range of modern inverters. A linear power warranty supports long term yield expectations and helps protect your investment. Its compact footprint and 20 kg weight simplify handling during transport and installation. The module is designed for versatile mounting on roofs, ground structures, and project based applications where consistent production is critical.
Reliable 315W output: The module delivers up to 315 watts under standard test conditions for strong energy yield. Output is supported by a positive power tolerance from 0 to 5 watts for added assurance during system design.
Durable construction for harsh sites: A 3.2 mm tempered glass front and double layer anodized aluminum frame provide excellent structural strength. Rated wind and snow loads up to 2400 Pa and 5400 Pa support use in challenging climates and exposed locations.
Proven monocrystalline cell technology: High quality monocrystalline solar cells enhance conversion efficiency and long term stability. The 66 cell layout balances voltage, current, and footprint for flexible string design and installation planning.
Extended linear power warranty: A 25 year linear power output warranty supports long term energy production. The panel retains at least 95 percent of rated power in the first year and at least 80 percent at year twenty five under the manufacturer’s terms.
Broad application versatility: The module is suitable for home rooftops, commercial buildings, and project based arrays. MC4 compatible connectors and standard 4 mm² cables make integration with existing balance of system components straightforward.
The Green Sun GSPV-315W monocrystalline 66 cell solar panel converts sunlight into direct current power through high efficiency silicon cells. Each 156 x 156 mm cell is encapsulated in EVA and protected by tempered glass to maintain performance over many years. When the panel is exposed to irradiance of 1000 W/m² at 25°C, it operates at its rated output under standard test conditions. The direct current produced flows through factory fitted 4 mm² cables and MC4 connectors into your inverter or charge controller. There, the energy is converted or regulated for use in AC loads, batteries, or hybrid systems. Designed for a maximum system voltage of 1000V DC, the module can be wired in series strings to match inverter input ranges. Its electrical characteristics, including open circuit voltage, short circuit current, and nominal operating point, help system designers size strings, fuses, and conductors accurately. This process runs silently and automatically whenever sunlight reaches the panel surface.
Monocrystalline energy conversion: The panel uses monocrystalline silicon cells to absorb photons from sunlight and free electrons. These electrons move through the cell structure and create a direct current, which is collected by busbars and output conductors.
Module protection and durability: EVA encapsulation and a TPT backsheet seal the cells against moisture and dust infiltration. The tempered glass front and rigid frame maintain mechanical integrity under wind, snow, and handling loads during the system lifetime.
System integration and output stability: The panel connects to matching modules in series or parallel to reach the desired array power and voltage. Its defined temperature coefficients for current, voltage, and maximum power allow more accurate performance predictions across varying climates.
