Renogy, flexible solar panel for 12-volt systems

Renogy 100 W Flexible Solar Panel (Black Division)

Also written as Renogy flexible 100W, Black Division 100W

A frameless 100 W panel that bends up to 240 degrees and weighs 5.3 lb, for curved or weight-limited roofs.

Not yet available

Best for

A curved RV, trailer or boat roof where a framed panel will not sit flat, or where every pound counts.

Strengths and limitations

Strengths

  • 5.3 lb (2.4 kg), against 14.5 lb for Renogy's rigid 100 W (Renogy).
  • Bends within 240 degrees (Renogy).
  • IP67 junction box; rated to 5,400 Pa snow and 2,400 Pa wind (Renogy).
  • Mounts with pre-drilled holes, silicone adhesive or velcro (Renogy).

Limitations

  • Lower voltage than the rigid panel: 23.5 V open-circuit, 19.4 V at max power (Renogy).
  • Renogy lists CE and ISO only; no UL listing named.
  • The spec table gives 0.8 in thick while a feature list says 0.1 in. We show the spec table figure.

What it does not do

  • Charge a battery on its own: it needs a charge controller.
  • Shed heat like a framed panel on an air gap: glued flat to a roof it runs hotter, and Renogy's FAQ notes heat reduces output. We have not measured how much.
  • Match the rigid panel's warranty: 5 years materials and workmanship (Renogy).

Power and travel notes

Real runtime is less than capacity divided by load: conversion losses, battery reserve and temperature all cut into it. Size a battery for your fridge.

Before you buy

  • Seal every roof penetration and follow the adhesive maker's surface prep; a roof leak costs more than the panel.
