SunPower Solar Panel Kit

Exclusive to Force4, these kits use genuine Sunpower semi-flexible panels and are bundled with a charge controller and 5m cables to create a complete solar charging package. SunPower’s world beating back contact Maxeon solar cells deliver up to 25% efficiency, that means more power from less panel. Sunpower are so confident that they provide a 5 year power guarantee, with no saltwater exclusions, as well as a 2 year product warranty for total peace of mind.

Each cell operates independently, so even if part of the panel is in shade they will still provide charge. The charge controller provided is a genuine 10A Spectra regulator. 5m of cabling and a wiring diagram complete this kit, so all you need to add is a few basic electrical connectors to suit your individual application.

Two panel sizes available:

50W Kit - Panel Dimensions 653 x 556mm

100W Kit - Panel Dimensions 1150 x 555mm

Questions & Answers
Questions & Answers
Can this be wired to feed two separate batteries? I have a standard 'battery 1' and 'battery 2' system Richard

No, this system is for charging a single battery as the charge controller doesn't have dual outputs. 

See Product code: 120121 for the dual battery charge controller.


Can I assume that the maximum output to expect would be 22.7 watts (ie 22.7% of 100watts)?This would be less than two amps at a nominal 12 volts. Peter Henery

The efficiency rating of a panel is a measure of the size the panel is for a given power output so a 17% efficient panel is simply larger than a 25% efficient panel of the same wattage.

Where the area available to place solar panels is a limiting factor the more efficient the panel, the greater the power per square meter.

This does not in any way change the rated power of the panel, only its size.


Can these be Bimini Mounted by zipper and velcro, or eyelets, / metal fasteners etc. without voiding the 5 year warranty? Michael Strawson

Yes this could be, there are 4 s/s eyelets in each corner that can be used for this. Making additional holes would then impact the warranty of the product 


I have 2 x 12v leisure batteries linked in series, will the 50W kit be sufficient to charge them both please? Phil Niles
A 50 Watt panel should be sufficient to charge 2 x 12V leisure batteries but I would recommend the 100W version as it will charge much faster and more efficiently.
Hi do you have a duel charger to go with the panel that has an hdmi input? Kirk
Hi Kirk, These kits come complete with a regulator to charge a battery. What do you mean by an 'HDMI' input please?
Is this panel suitable for mounting to a companionway slide-hatch. And if so how would it best be mounted? Sikaflex? Mr B Murphy
The solar panel has a maximum height of 20mm, if there is this or greater clearance then yes it can be mounted on the slide hatch. Secondly this can be mounted with a sealant/adhesive or there is 4 S/S eyelets for bolts, screws or hooks for mounting.
If the solar panel kit is permanently wired to the battery, is it protected from the reverse flow of electricity produced by the engine's alternator? Alan

Yes the Regulator provided has over current & reverse discharge protection. So no damage to the solar panel.



Can you charge a 24v system with this Graham Rampling
these are 12v systems, if you would like, we can contact our supplier and see if they can get in a 24v version for you, just give us a call on 03451300710 15/03/22
Can the Sunpower panels be flexed across their width (as well as along their length)? Bob
Hello Yes they can be flexed across their width or length, although I don't think they would flex across both together too easily / well. 20/01/22 CW
