Model GSPV-285W (156M)66 | Monocrystalline Silicon | 66 Full Cells 156 x 156 mm | Monofacial | 1000V DC System Voltage
The Green Sun Solar GSPV-285W (156M)66 monocrystalline solar panel delivers reliable 285W output for homes and businesses. This versatile module belongs to a performance range from 285W to 315W, ideal for grid-tied and off-grid systems. Its 66 high quality monocrystalline cells are engineered for stable power production in real world conditions. A rugged 3.2 mm tempered glass front and anodized aluminum frame protect the panel in harsh climates. The design withstands strong winds and heavy snow, which supports long term field performance. With a 1000V DC system rating, the panel integrates easily into modern residential or commercial arrays. Positive power tolerance from 0 to 5W helps ensure dependable output during the panel’s lifetime. This Green Sun Solar GSPV-285W module is a strong choice for installers seeking proven, bankable panels. It suits rooftop installations, small commercial systems, and project based solar deployments worldwide.
Reliable 285W Power Class: Each module delivers up to 285W under standard test conditions. The series extends to 315W, supporting flexible array design and easy system sizing.
High Quality Monocrystalline Cells: Premium 156 x 156 mm monocrystalline cells improve conversion of sunlight into electricity. The 66 cell layout supports balanced voltage and current for modern inverters.
Durable Construction for Harsh Sites: The module uses 3.2 mm tempered glass, EVA encapsulation, and a TPT backsheet. This structure protects cells from moisture, impact, wind loads, and heavy snow conditions.
Positive Power Tolerance: With a 0 to +5W power tolerance, the panel often produces at or above its rated output. This supports stronger energy yields and more accurate system performance estimates.
Long Term Warranty Protection: Green Sun backs the module with material and power output warranties. Linear performance coverage provides added confidence in long term energy production.
The Green Sun Solar GSPV-285W panel converts sunlight into usable DC electricity through its monocrystalline cells. When sunlight hits the silicon cells, photons dislodge electrons and create an electric current. Each of the 66 interconnected cells contributes voltage and current, forming the module’s rated power output. The EVA encapsulant locks the cells in place and protects them from vibration and moisture. A TPT backsheet provides electrical insulation and shields the rear of the cells from environmental stress. The tough tempered glass and aluminum frame create a rigid, weather resistant package for rooftop or ground mounting. Pre-installed MC4 compatible connectors and 4 mm² cables allow fast connection to string wiring. Once connected to an inverter, the DC power is converted to AC power for building loads or grid export. This process runs automatically whenever sufficient irradiance reaches the panel surface. The panel therefore forms a critical building block in residential and commercial solar power systems.
Monocrystalline Energy Conversion: The panel uses high purity monocrystalline silicon cells to convert sunlight into DC electricity. The uniform crystal structure improves electron flow, which supports stable output even in varied conditions.
Module Encapsulation and Protection: Cells are encapsulated in EVA and laminated between tempered glass and a TPT backsheet. This layered structure protects against moisture, dust, and mechanical impact during the panel’s operating life.
System Integration and Output: The 1000V DC maximum system voltage rating supports longer strings and efficient cabling. MC4 compatible connectors and 900 mm leads simplify integration with inverters and combiner boxes.
