120w Rigid Mono High Density Solar Panel Roof and Deck Top Kit

The 120w PV Logic MHD roof and deck top kit is an all in one bundle to professionally fit the panel to the roof of a caravan, campervan, motorhome or boat with everything you need supplied in one box. This kit is perfect for higher than average power loads often needed in larger rigs. The power drain from DC appliances, such as refrigeration, and AC loads (for example microwaves) can be compensated for by this panel in all but the darkest months of winter. Supplied with our custom made all black and low profile aero brackets, this kit will enhance the appearance of any roof top whilst keeping additional wind drag to the bare minimum and removing the potential for wind noise nuisance. Supplied as standard with our 10Ah PWM dual battery charge controller (which can be upgraded if required), cable feed gland, bonding agent, fuse, terminals and instructions. ... View more

Product information


Build your perfect roof and deck top kit starting with a premium solar panel 

With two power ratings of 120w and 155w, our rigid MHD 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. For more information about what sets the PV Logic Rigid MHD range apart from other solar panels click here.

A charge controller should be used with the 120w and 155w rigid MHD solar panels to protect the battery from being overcharged and to prevent reverse current drain.

Put yourself in control

All our charge controllers are capable of charging 12V and 24V single or dual batteries.

The MPPT Pro charge controller increases solar yield by up to 20% over a standard charge controller by artificially modifying the voltage from s solar panel system to actively match any battery's requirements.  This means that whatever the weather conditions your panels will deliver maximum power with minimum electrical loss.

The MPPT charge controller comes with its very own free-to-download Bluetooth app (Apple and Android) to display how the solar system is performing. The app software links your smartphone to the MPPT Pro and shows performance figures for a single or dual battery/batteries - very useful in a motorhome where the system can intelligently charge the leisure and starter batteries.

An optional Activity Monitor is also available with the MPPT Pro to provide all performance data on a LCD display.

Bespoke black aero brackets 

Our custom made MHD aero fitting brackets mean the entire assembly has a combined depth of just 40mm as the panels hug the roof line much more closely than a normal solar panel. As well as the super smart black, aero brackets, the roof and deck top kits come with a 10Ah charge controller plus the opportunity to upgrade the charge controller to the MPPT Pro.
