Go Power! 550-Watt Solar Flex™ Kit Delivers Flexible High-Output Solar Power for RVers, Off-Grid Adventurers, and Mobile Businesses
When you’re 200 miles from the nearest campground hookup or parked on a jobsite with no utility access your power source needs to be as adaptable as you are. The Go Power! 550-Watt Solar Flex™ Kit is Go Power!’s largest and most capable flexible solar kit, engineered to deliver serious, self-sufficient solar energy wherever life or work takes you. Whether you’re full-timing in your RV, cruising on a boat, running tools on a remote worksite, or building an off-grid homestead, this kit gives you the muscle and the flexibility to keep your power flowing without the bulk.
Pairing 550 watts of ultra-thin monocrystalline solar panels with a 60-amp MPPT Pro Solar Controller, the GP-FLEX-550 is a complete, ready-to-install solar charging solution. It’s not just a solar panel kit it’s a power system designed by people who understand what it means to live and work off the grid.
At Outbound Power, we don’t just sell solar equipment we help you build power systems that perform when it matters most. The Go Power! 550-Watt Solar Flex™ Kit represents some of the most thoughtful engineering in the flexible solar market: genuinely high output, a form factor that works in the real world, and a controller smart enough to make the most of every hour of sun. Whether you’re a weekend warrior, a full-time nomad, or a professional who depends on off-grid power, this kit delivers lasting, reliable value.
Go Power! 550-Watt Solar Flex™ Kit Features
Bends to Fit Any Roof Without Needing Custom Mounts
Panels flex up to 30 degrees, conforming naturally to curved RV and boat surfaces. No brackets, no rails just stick or screw them down and you're done. Installation has never been this straightforward.
So Thin and Light You'll Forget They're Up There
At just 3mm thick and 82% lighter than rigid panels, these modules sit nearly flush with your roof. Less weight means less stress on your vehicle, and less drag means better fuel economy on long drives.
Monocrystalline Cells Squeeze More Power From Less Space
High-efficiency monocrystalline cells generate more electricity per square foot than any competing panel type. When your roof space is limited, every inch matters. You get maximum solar output without needing a bigger surface area.
The MPPT Controller Captures Up to 30% More Energy Daily
Unlike basic PWM controllers bundled with cheaper kits, the included 60-amp MPPT Pro Controller actively optimizes power harvest in real time. That means fuller batteries, sooner even on partly cloudy days when every watt counts.
Monitor Your Entire Solar System From Your Phone
The included Bluetooth dongle and digital remote display let you check panel output, battery charge status, and system performance wirelessly. No crawling into equipment bays just open the app and see exactly what your system is doing.
Built Tough Enough to Handle Life on the Road
The durable panel surface resists UV exposure, vibration, and temperature swings that come with mobile living. Flexible construction also reduces the risk of internal cell cracking over time, making these panels a genuinely long-lasting investment.
A 5-Year Warranty Backs Every Panel in the Kit
Go Power! stands behind the Solar Flex™ panels with a 5-year power output warranty one of the strongest guarantees in the flexible solar market. Buy with confidence knowing your investment is protected for years of real-world use.
Go Power! 550-Watt Solar Flex™ Kit Warranty
Go Power! provides a 25-year warranty policy, ensuring the absence of defects in materials, workmanship, and performance during the warranty period.

This works very well. I can charge my unit and expansion batteries more than twice as fast as using a 120 volt wall outlet. I think it also helps with the battery temperature.
