20W 12V Sunshine Solar Flexible ETFE Range

Designed for versatility, this 20W panel is perfect for maintaining and trickle-charging 12V leisure batteries, helping to support onboard lighting, small appliances, and essential systems. It is an excellent choice for users seeking a compact solar solution to support travel, camping, or off-grid living. 

Its flexible construction allows it to be installed on curved or uneven surfaces where traditional rigid panels may not be suitable. This makes it particularly well-suited for caravans, motorhomes, boats, campervans, and other mobile or space-limited applications. Whether mounted on a roof, deck, or other contoured surface, the SFB20B provides a practical and efficient solar charging option without adding unnecessary weight. 

 The ETFE coating enhances performance by improving resistance to UV exposure, moisture, and salt corrosion, making it especially suitable for marine environments. Combined with monocrystalline cell technology, the panel delivers consistent output in a variety of lighting conditions.

With a Sunshine Flexible ETFE 20W 12V solar panel you could expect to generate around 5.5 amps per day when used in conjunction with a PWM solar charge controller and 7 amps per day when used with an MPPT solar controller during the summer months. Multiple panels can be connected to acquire higher power if needed.
