Go Power FLEX-110 & FLEX-220 Solar Panel Installation Guide

The Go Power GP-FLEX-110, GP-FLEX-110E and GP-FLEX-220 are low-profile solar kit configurations built around 110W flexible modules. This guide separates complete charging kits from expansion packages and explains how roof mounting differs from rigid-frame Z-brackets.

Low-profile panel mounting and solar power path

Go Power provides adhesive or fastener mounting options for these flexible modules. Their panel design can follow a gently curved surface, up to the manufacturer's stated 30-degree curvature. Appropriate adhesive or sealant is not included; its selection depends on the actual roof material.

Mounting warning: Go Power states that adhesive mounting can be permanent. Check placement and module operation before fixing it to the roof. Secure every panel using the approved installation method and seal each roof penetration properly.

Choose a complete kit or an expansion kit

Exact kit Rated PV power Panel configuration Package distinction
GP-FLEX-110 110W One flexible 110W panel Charging kit with controller; verify the controller revision
GP-FLEX-110E 110W One additional 110W panel Expansion hardware; no separate solar charge controller
GP-FLEX-220 220W Two 110W flexible modules Complete kit with charging equipment

Go Power identifies the FLEX-110E as a 110W expansion package with a module, solar branch connectors, mounting screws and reverse-blocking diodes. It does not supply a new charge controller. A complete GP-FLEX-110 has 25-foot positive and negative solar output cables and a model-specific 30A controller; confirm whether the shipped unit has the current or older controller revision.

Some Go Power publications show differing module electrical specifications across revisions. Compare the panel's own identification label and exact datasheet before adding modules in series or parallel. Do not assume all Go Power 110W panels share the same Voc, Imp or connector type.

Installation: Verify the RV roof construction, approved mounting chemistry, waterproofing instructions and panel electrical ratings. PV circuits remain hazardous in sunlight. Use qualified installation help for structural penetrations or electrical changes.
