The AllSpark AS-135SPGLG2 135W Glass Solar Panel delivers dependable, self-sufficient power wherever the road takes you across Australia. Built around high-efficiency monocrystalline silicon cells encased behind a tough 3.2mm low-iron tempered glass face, this rigid panel converts sunlight into usable 12V or 24V DC power with outstanding consistency — even under the extreme heat and high-UV conditions that define Australian summers. With a peak output of 135W, an operating voltage of 18.0V (Vmp) and a short-circuit current of 8.10A, it delivers meaningful daily charge to keep your batteries topped up whether you're parked up in the Kimberley or camping along the Great Ocean Road.

Designed for serious Australian caravanners, camper trailer owners, 4WD adventurers, and motorhome travellers, the AS-135SPGLG2 installs quickly and confidently thanks to pre-drilled mounting holes on its anodised aluminium alloy frame and pre-fitted MC4-compatible connectors that pair directly with MPPT and PWM solar regulators — no tools required. The IP65-rated weatherproof junction box keeps electrical connections sealed against dust, rain, and road grime across long outback runs. Compatible with AGM, GEL, SLA, and lithium LiFePO4 battery systems, it suits virtually every 12V and 24V setup on the market — from entry-level camper trailers right through to sophisticated off-grid RV power systems.
