50W Semi-Flexible Solar Panel with Integrated Charge Controller and Butyl Adhesive (R3-15F13.7VB)

Solar panels extend battery life, reduce jumpstarts, provide diesel savings, enable telematics and maintain battery voltage during extended off cycles.

PowerFilm designed this Soltronix 50W Semi-Flexible Solar Panel with Integrated Charge Controller to simplify solar charging. The 50W solar panel includes semi-flexible fiberglass backing, full backside butyl adhesive, and an integrated fixed power point (FPPT) charge controller.

Compared to other panels on the market, the FPPT integrated charge controller delivers more power to the battery and provides faster installation. Industrial-strength butyl adhesive across the entire backside of the panel ensures a tight bond to the vehicle or trailer and eliminates bond failures due to water freeze-thaw cycles.

What's included:

• 50W Semi-Flexible Solar Panel with Integrated Charge Controller and Butyl Adhesive (R3-15F13.7VB)

Cable Options:

• 25ft. Coroplast Wrapped Extension Cable with O-ring Connectors (CA1225WPRTCF)
• Custom cable lengths, connections, and wire wrap are available depending on requirements (cable not included).

Benefits:

• High-efficiency SunPower/Maxeon cells require less area on fairings and limit power reduction due to hail damage/strikes
• Integrated FPPT charge controller results in faster installation and more power than traditional PWM charge controllers
• Full backside Industrial strength butyl adhesive provides the best bond to truck or trailer
• Semi-flexible design enables easy attachment to fairings or hoods
• Rugged, self-cleaning encapsulation

Power Comparison

Comparison Graph Notes

• Panel manufacturer and advertised panel output.
• Plot points are calculated outputs from the IV curve.
• MPPT / FPPT controllers aren’t commonly found with panels under 100W. 
• The largest drop in power to the battery occurs when the panel voltage is higher than the battery requirement. Traditional PWM charge controllers discard power above the current battery level.

All connections must be solar positive (red) to battery positive and solar negative (black or blue) to battery negative. Reversing can damage the solar panel. Consult your battery manufacturer if you have questions about the specifications of your battery.
