The Sunstore 100W Deluxe is a straightforward fixed-panel solar kit for campervans, caravans and motorhomes. It is designed to maintain one leisure battery and support modest 12V use, with the panel, controller, mounting hardware, cabling and roof-entry equipment supplied in one package.


The main caveat is that the Deluxe uses a PWM charge controller, not MPPT. PWM can be adequate for a simple lead-acid battery system, but MPPT generally extracts more energy from the same panel, particularly in cooler, cloudy or changeable conditions.
The Deluxe is worth considering if you already have a compatible battery system or find it at a clearly lower price. If you are starting from scratch, compare the 100W MPPT version before ordering. You will also need to buy a leisure battery and inverter separately if required.

Review note: We haven’t personally installed this kit. Our assessment is based on its current specification, controller documentation, Sunstore’s support information and comparison with the other 100W kits in its range.

What Do You Get?
The Deluxe is intended to include most of the main components needed for a fixed solar installation on a campervan, caravan or motorhome.
The kit typically includes:
- 100W monocrystalline solar panel
- ViewStar AU 10A PWM charge controller
- Choice of mounting brackets
- Roof cable-entry gland
- Bonding adhesive
- Solar cable and MC4 connectors
- Fuse and electrical fittings
- Installation instructions
The battery and inverter are not included. Check the current product listing for the exact controller model, panel dimensions, cable lengths, mounting option, battery compatibility and warranty terms, as kit contents can change with availability.
Which Sunstore 100W Kit Should You Choose?
The main difference between Sunstore’s 100W vehicle kits is the controller and the number of batteries they are designed to charge.
| Version | Controller | Batteries Charged | Best For |
|---|---|---|---|
| 100W Deluxe | PWM | 1 | Simple lead-acid leisure-battery setups |
| 100W MPPT | MPPT | 1 | Most new single-battery installations |
| 100W Duo | Dual-battery controller | 2 | Leisure and starter battery charging |
| 100W MPPT Duo | MPPT dual-battery | 2 | Two-battery systems needing MPPT |
Our Pick for Most Buyers
The Deluxe makes sense if you already have a straightforward lead-acid leisure-battery setup or if it is substantially cheaper than the alternatives. PWM is a simple, established technology and can work adequately when the panel, controller and battery are correctly matched.
For a new single-battery installation, we would generally pay the modest extra for the MPPT version where possible. MPPT controllers can make better use of the panel’s operating voltage and may provide more useful charging performance in cool, cloudy or variable conditions.
Choose a Duo version only if you specifically want to charge both a leisure battery and the vehicle’s starter battery. If you only need to charge one battery, the Duo models add cost and complexity without a meaningful benefit.
What Can a 100W Solar Panel Realistically Power?
The panel does not normally power appliances directly. It replenishes the leisure battery through the charge controller, and the battery then supplies your lights, pumps, USB sockets and other 12V equipment.
A 100W system can be useful for:
- Maintaining a leisure battery while parked
- LED interior lighting
- Charging phones, tablets and other USB devices
- Small 12V accessories and water pumps
- Weekend campervan or caravan trips
Actual output varies with cloud, shading, panel angle, dirt, cable losses, battery condition, season and daylight hours. A 100W panel should therefore be viewed as a battery-charging and maintenance system rather than a complete off-grid power solution.
It may struggle to replace all the energy used by a regularly running compressor fridge, frequent inverter use, heating fans, high-power appliances or several days of winter off-grid use. Kettles, coffee machines and similar appliances can consume more energy than the panel replaces on a poor-weather day.
For heavier use, consider a larger solar array, a larger battery bank or another charging source such as a mains charger or DC-to-DC charger. Sunstore positions roughly 100–150W as a sensible range for many UK campervans, but this remains a general guide rather than a guarantee of output.
Not sure whether 100W is enough for your setup? Use our free Solar System Sizing Tool to estimate the panel, battery and inverter capacity you actually need.
Battery Compatibility
Check the controller’s charging profile before connecting a battery. Traditional flooded lead-acid, AGM, gel and lithium batteries can require different settings.
The supplied ViewStar AU should not automatically be assumed suitable for a lithium battery. Confirm that the controller supports your battery chemistry and that the correct charging profile can be selected before connecting it.
Installation: What Is Involved?
This is a complete installation kit, but it is not a plug-and-play appliance. Installation normally involves bonding the panel brackets to the roof, fitting the cable-entry gland, routing the cable, connecting the controller to the battery and installing the supplied protection.
The controller should be mounted somewhere dry, accessible and reasonably close to the battery, with adequate ventilation. The roof must be clean and dry, and the bonding product must be applied and cured according to the instructions.
Follow Sunstore’s current wiring and installation guidance. If you are unsure about cable sizing, fusing, battery connections or roof sealing, use a qualified installer.

- Uses PWM rather than MPPT
- Battery and inverter sold separately
- 100W is limited for heavier off-grid use
- Installation requires roof work and electrical connections
Is the Sunstore 100W Deluxe Worth It?
The Sunstore 100W Deluxe is a sensible choice for a straightforward vehicle solar system designed to maintain one leisure battery and support modest 12V use. Its complete hardware package makes installation planning easier, and PWM is adequate for many simple lead-acid setups.
If you already have a compatible system or the Deluxe is substantially cheaper, it remains worth considering. For most buyers starting from scratch, compare the price of the 100W MPPT version and choose that instead if the difference is modest. It offers the more efficient controller technology and greater headroom from the same roof space.
Before ordering, check the current price, controller model, panel dimensions, battery compatibility, mounting option, cable lengths and warranty terms.
For light-use vehicle solar, the Deluxe can do the job. For a new single-battery installation, the 100W MPPT version is our stronger recommendation. If you need something much larger for a cabin, workshop or fixed off-grid setup, see our guide to the best off-grid solar kits in the UK.
