Product information


With power ratings from 5W to 200W, our rigid solar panels fulfil a variety of  energy needs ranging from a continuous trickle feed of power to prevent battery drain in caravans, motorhomes and boats to creating energy self-sufficiency for off-grid travel.

Our rigid panels also deliver energy to remote power systems, such as electric fences and gates as well as pumps in garden ponds.

Rigid solar panels rated 80W and above include bypass diodes to minimise the effect of shadows so that energy generation is maximised.

All solar panels are supplied as basic kits and include a 5m cable, a fuse, two crocodile clips and six ring terminals for connections plus detailed user instructions.

Rigid solar panels of 20W and above should be used with a charge controller to protect the battery from being overcharged and to prevent reverse current drain. Browse our range of charge controllers here or buy your panel as a kit (with a cost saving of  up to 20%) with a charge controller and the option of stands, brackets or fixings here
