説明
A rigid solar panel asks the roof to accommodate it. A flexible panel accommodates the roof. That inversion is the entire argument for this array, and it is the reason a curved camper roof, a narrowboat cabin, or a balcony rail can carry generation capacity that would otherwise be structurally impossible to mount. The Foldlight Array is built from monocrystalline silicon laminated into a two and a half millimetre profile, thin enough to follow a gentle curve and light enough at 1.6 kilograms per hundred watts that no additional framing is required.
Each hundred watt panel delivers a maximum power voltage of 18 volts, a maximum power current of 6.25 amps, and an open circuit voltage of 19.2 volts, with cells arranged thirty-three in series at 157 millimetres square. The usable face measures 970 by 530 millimetres, and the connection is a 0.9 metre lead in two core 2.5 square millimetre cable, terminated for a standard photovoltaic plug. Monocrystalline construction returns more energy per unit area than polycrystalline at the same rating, which matters most in the shoulder seasons and in partial shade, where every watt of harvest is contested. Two surface options are offered: a PET laminate for fixed installations where cost-efficiency dominates and the panel will not be repeatedly handled, and an ETFE laminate for mobile use, where the surface must tolerate abrasion, salt air, and repeated flexing without clouding.
The array scales with the job rather than the reverse. A single panel with a ten amp controller maintains a caravan or boat battery. Two panels and a twenty amp controller handle a load that includes a compressor fridge. Three panels and a thirty amp controller form a system capable of keeping a small off-grid cabin charged through the summer. Each system listing includes the panels, the appropriate controller, an adapter to combine the panel outputs, a three metre cable with photovoltaic connectors, and a one metre lead with alligator clips for direct battery connection. Operating temperature spans minus twenty to plus sixty-five degrees Celsius, with a temperature coefficient of minus 0.38 percent per degree on maximum power, so the derating on a hot day is predictable rather than mysterious.
Carry the array to the light, rather than the light to the array.

Where It Belongs
Roof curves are the obvious case. Campervans, motorhomes, and narrowboats have surfaces that a rigid framed panel cannot sit on without standoffs and drilling, and this array follows those radii directly. Marine installations use the ETFE variant because salt air and constant UV exposure punish anything less. Balcony and window-rail projects mount the lightweight panels vertically where a conventional panel would be a structural imposition, and remote monitoring stations, electric fences, and gate controllers use a single panel with a ten amp controller as a maintenance-free supply. Off-grid cabins order the three-panel system and treat it as a seasonal charger for a battery bank that carries them through winter. Because each hundred watt panel weighs under two kilograms, a single person can carry a three-panel array to a site with no vehicle access - which is often the constraint that decides whether a remote installation happens at all.
Frequently Asked Questions
Q: Which laminate should I choose, PET or ETFE?
A: Choose PET for fixed installations where the panel stays mounted and cost-efficiency matters most. Choose ETFE for anything mobile or exposed - campers, boats, and roof racks - because the ETFE surface resists abrasion, salt, and repeated flexing without the clouding that eventually affects a softer laminate.
Q: What is included in a system listing?
A: A 100W system includes one panel, a 10A controller, a three metre PV cable with connectors, and a one metre alligator-clip lead. The 200W system adds a second panel, a 2-in-1 combiner adapter and a 20A controller. The 300W system adds a third panel, a 3-in-1 adapter and a 30A controller. Panel-only listings ship without the controller.
Q: Can I mount it on a curved surface?
A: Yes. At 2.5 millimetres thick the panel follows gentle curvature. For trailer roofs and boat cabins, we recommend bonding with a suitable adhesive and avoiding hard creases, which stress the cells even when the laminate survives.
Q: How much power will I actually get?
A: Expect the rated output under full sun with correct orientation. Real-world harvest depends on angle, temperature, and shading. The panels derate by about 0.38 percent per degree above standard test conditions, so a hot afternoon produces slightly less than a cool one, and partial shade across a series string reduces output more than the shaded area suggests.
Q: Will it charge my battery directly?
A: Connect through the supplied controller rather than to the battery directly. The controller regulates charge and prevents over-voltage, and the alligator-clip lead is provided for that connection. Always confirm the battery has sufficient voltage for the controller to recognise its type before first use.
Q: What about remote delivery areas?
A: The panels ship from warehouses in Spain, the Czech Republic, and Belgium for fast European delivery. Certain remote postal zones served by local carriers are outside the delivery network from those warehouses; if your postcode falls in one of those areas, our support team will confirm before dispatch and arrange an alternative route where possible.
The EastSupplier Promise
Every unit ships from our overseas warehouse network after a hands-on inspection pass. We verify the plug type, count the parts, and confirm the unit powers on before it leaves the shelf. If a component arrives damaged, our support team responds within one business day with a replacement or a refund - not a script. We have supplied industrial buyers, workshops, and distributors since 2010, and the same standard applies to a single order as to a pallet.
