Ameresco 20M Solar Panel Benefits

 

Easier bolt management
Bolts may be located anywhere along the channels; the channel groove is specially designed to prevent the bolt from rotating when tightening, allowing installation with just one wrench.

 

Long cable for easier batttery connections
A 15 ft. 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.

 

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.
