Ameresco Solar 40J 40Watt 12VDC Polycrystalline Solar Panel w/ Junction Box

Manufacturer Part#: 40J

This line of modules is the direct result of over three decades of design, manufacturing and use. Attending to every detail in the design and manufacture of our products, our process controls and testing methods have optimized module life and electrical energy production.

Features

  • Built To Last - From mountaintops to off-shore platforms, on weather stations in the bitter cold of Antarctica and on telephone signal repeaters in the hot Australian outback, the technology has been proven in the harshest environments
  • Accessible Junction Box for Off-Grid Connections - J-type junction box has accessible terminals for easier module interconnections in off-grid applications, and it allows fitting cable glands for various sections
  • High Reliability - Cell interconnections and diode placement use well-established industry practice and are field-proven to provide excellent reliability
