Fixed / Rigid / Glass Solar Panels

Fixed Glass Solar Panels for Caravans, 4WDs and Off-Grid Systems

Fixed solar panels are a common choice for permanent mounting on caravan roofs, 4WD roof racks, canopies, boats and off-grid sheds. A tempered glass face and aluminium frame give a rigid, weather-resistant panel that handles heat, vibration and corrugations well over the long term. This collection covers rigid panels from compact 20W units up to 475W, in 12V, 24V and 48V nominal configurations.

Brands and Panel Options in This Range

The range brings together several established solar brands, so you can match output, footprint and frame style to your build:

• Fusion series fixed panels: 20W to 300W, including narrow 80W and 115W models for tight roof racks, shade-resistant 220W, 250W and 300W versions, and a 220W 48V version.
• Victron monocrystalline panels: 20W to 345W, plus a 45W polycrystalline option for small trickle-charge setups.
• Enerdrive fixed panels: 55W to 200W in black or silver frames, including 24V 40W, 100W and 200W models and 120W polycrystalline options.
• SunPower Maxeon3 410W: a shade-resistant, all-black panel for high output from a single module.
• Risen 475W N-Type TOPCon bifacial: a high-wattage panel suited to larger off-grid, shed and ground-mounted arrays.

Fixed vs Flexible Panels

Rigid glass panels sit above the mounting surface on brackets, which allows airflow underneath to help manage operating temperature. They suit installations where weight is less critical and long service life matters. If you need a low-profile, adhesive-mounted option for curved surfaces or weight-limited vehicles, compare our flexible solar panels. For mounting hardware choices and bracket placement, see the glass solar panel mounting guide.

Selection Tips for Fixed Solar Panels

Measure your space first. Roof racks and caravan roofs often have hatches, air-conditioners and awnings that limit layout. Narrow panels and square formats can make better use of available area than a single large module.

Match voltage to your controller and battery. Most caravan and 4WD systems use 12V panels with an MPPT or PWM regulator. Larger arrays or long cable runs may benefit from 24V solar panels or the 48V option, paired with a suitable MPPT controller.

Consider partial shade. Roof racks, antennas and trees cast shadows. Shade-resistant Fusion models and the SunPower Maxeon3 are designed to reduce output loss under partial shading.

Choose wattage by daily use. A 100W to 200W fixed panel is a typical starting point for a fridge and lighting on a 4WD, while caravans running inverters or larger batteries often need 300W or more across one or several panels.

Browse the fixed solar panels above, compare dimensions and output specifications, and choose the rigid panel that fits your roof and power needs for dependable off-grid charging on your next trip.
