BougeRV 100W CIGS Flexible Solar Panel & Sunflow 40A MPPT Solar Charge Controller
BougeRV 100W CIGS Flexible Solar Panel & Sunflow 40A MPPT Solar Charge Controller
We have limited reviews of solar panels due so many YouTube videos and blogs that have covered the topic. We left the door open for a solar panel review in the event we found a unique product that would be beneficial for RV travel. And we found one!
We tested the BougeRV 100W CIGS Flexible Solar Panel with the Sunflow 40A MPPT Solar Charge Controller. The flexible solar panel has a wide range of applications with its solar performance, durability, lightweight, and flexibility for even the most challenging installation. And the Sunflow 40A MPPT solar charger is feature rich and took minutes to install and configure. A great pair for the RV traveler needing solar power.
BougeRV 100W CIGS Flexible Solar Panel
The solar panel is designed to be extremely flexible and we tested dozens of times bending over 270 degrees end to end with no change in the panel surface or damage to the solar cells. The panel is lightweight at 4.6 pounds and can be mounted on a wide range of surfaces using the reinforced gussets or an adhesive.
Features
CIGS solar cell is a full copper indium gallium selenide solar cell, thin-film photovoltaic device that uses semiconductor layers of copper indium gallium selenide (CIGS) to absorb sunlight and convert it into electricity.
- Flexible – Can fit around curved structures, flexible for all shapes.
- Stable output – Stable output can still be guaranteed in shadow occlusion environments.
- Waterproof – Suitable for wet environments.
- Lightweight – No frames, no special stands or mounting brackets needed.
- Glass Free – Nothing to be broken.

We have plans for a larger solar installation and didn’t permanently install. To test the BougeRV 100W CIGS Flexible Solar Panel, we set up a lithium battery, installed the solar charger, and ran 20 feet of 10 gauge wire to the panel to simulate a typical roof install.
We tested the panel mid December on a sunny day knowing the angle of the winter sun would be less than optimum to maximize solar panel wattage production. As expected we were able to create 50 watts from the panel.
BougeRV Sunflow 40A MPPT Solar Charge Controller
To test the solar panel, we used the BougeRV Sunflow 40A MPPT solar charger controller. Installation was very simple and configuration using the Bluetooth smartphone app was straightforward with the entire process taking minutes.
The solar controller has a wide range of robust features. The controller can adjust the charge current from 0A to 30A and its high tracking efficiency is up to 99.5% with a peak conversion efficiency up to 99%.
The controller is compatible with Lithium LiFePO4 batteries. One of the challenges with lithium batteries is sub-freezing (32°F) temperatures where a charge will permanently deteriorate performance and safety. The BougeRV Sunflow 40A MPPT solar charge controller can protect lithium batteries supporting low-temp cut-off at the solar charge controller end. The controller can also restart or activate dormant lithium batteries that are turned off due to short circuits or excessive amp draw.
We especially liked the smartphone remote control app with a Bluetooth range up to 32 feet. Using the app inside our 5th wheel living area we were able to stay informed with the charging and performance of the attached solar panel, lithium battery and solar charge controller.

Final Thoughts
The BougeRV 100W CIGS Flexible Solar Panel has a wide range of applications in its 100W and 200W capacities. With it’s flexibility and ease of installation the solar panels are an excellent option for RV’s of all styles, vans, buses, as well as marine applications.
The BougeRV Sunflow 40A MPPT Solar Charge Controller is an affordable solution for small to mid-sized solar installations, yet offers the features needed to charge and manage RV, marine, and off-grid solar projects.
