Mechanical & Structural Features
  • Dimensions: 1535*765*35mm (larger surface area for higher energy capture)
  • Weight: 12.38kg (balanced for easy handling and installation)
  • Solar Cells: Monocrystalline 182*91mm (4*16pcs) - high-purity cells for superior efficiency
  • Front Glass: 3.2mm tempered glass (enhanced light transmission, impact resistance, and self-cleaning)
  • Frame: Anodized aluminum (corrosion-resistant, lightweight, and durable)
  • Junction Box: IP67 rated (waterproof, dustproof, and heat-resistant)
  • Output Cables: 90cm (customizable length) with MC4-compatible connectors (plug-and-play connectivity)
  • Mechanical Load: Front side max 5400Pa, rear side max 2400Pa (withstands strong winds and heavy snow)
Temperature Characteristics
  • Pmax Temperature Coefficient: -0.350%/°C (minimal power loss in high temperatures)
  • Voc Temperature Coefficient: -0.270%/°C (stable voltage output across temperature ranges)
  • Isc Temperature Coefficient: +0.048%/°C (slight current increase in cold weather)
  • Operating Temperature: -40°C to +85°C (performs reliably in extreme climates)
  • Nominal Operating Cell Temperature (NOCT): 45±2°C (real-world performance under standard conditions)
Why Choose JST-EXMH-(220-240)W?
Unmatched Efficiency
Up to 20.44% module efficiency (240W variant) - generates more power per square meter than most competitors
24V System Optimized
Vmp (18.60-19.06V) aligns perfectly with 24V battery charging, reducing energy loss
Scalable Design
700Vdc max system voltage supports large-scale series connections for utility-grade or industrial projects
Industrial-Grade Durability
IP67 junction box, 3.2mm tempered glass, and 5400Pa wind/snow load resistance ensure decades of reliable service
FAQ

Q: Can this panel charge a 48V battery?

A: Yes! Wire two panels in series (total ~37-38V) for 48V battery systems (with a compatible charge controller).

Q: How many panels fit on one pallet?

A: 36 panels per pallet (dimensions: 1585*1100*885mm; weight: 420kg).

Q: Is it suitable for coastal areas?

A: Absolutely. The IP67 junction box and corrosion-resistant aluminum frame withstand salt, moisture, and UV degradation.

Application Scenarios
  • Residential Rooftops: Ideal for homes seeking to reduce electricity bills or achieve energy independence
  • Commercial Buildings: Powers small businesses, warehouses, or retail stores (reduces operational costs)
  • Off-Grid Cabins: Provides primary power for remote homes, farms, or eco-resorts
  • Telecom/Utilities: Powers remote cell towers, weather stations, or grid-tied backup systems
  • Mobile Applications: Heavy-duty RV solar systems, large boats, or mobile command centers

This panel is engineered for scale, reliability, and performance — making it the ultimate choice for projects where every watt counts.
