Ameresco Solar 20M 20Watt 12V Polycrystalline Solar Panel w/ Multimount Frame

Manufacturer Part#: 20M

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.

  • 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
  • Multiple Mounting Possibilities - Multimount frame allows even greater flexibility in mounting. Positioned parallel to the edge and back of the module, its dual channels accept either M8 or 5/16” hex-head bolts, allowing the module to be mounted from the side or back
  • Long Cable For Easier Battery Connections - A 4.6 meter PVC-jacketed AWG 18-2 polarized cable is potted into the fully sealed junction box located on the module back. The module’s electrical connections are sealed for prevention against corrosion and moisture penetration

The Ameresco Solar 20M is certified for use in Class 1 Division 2.
