Redarc SPRP1180B 180W Black Monocrystalline Fixed Solar Panel

12V • 180W • Monocrystalline • Fixed Mount Panel

Product Overview

The Redarc SPRP1180B is a high-output 180W fixed monocrystalline solar panel designed for permanent installation on 4WDs, caravans, RVs, camper trailers, and marine vessels. As part of Redarc’s premium solar range, it delivers reliable off-grid power for travellers and professionals who need dependable battery charging in remote environments.

Using high-efficiency monocrystalline cells, the SPRP1180B provides consistent performance, even in less-than-ideal sunlight conditions. At 180 watts, it generates enough energy to run fridges, lights, water pumps, communications gear, and other 12V appliances, reducing reliance on generators and powered campsites. This makes it an excellent choice for extended touring, off-grid living, and marine use.

Built for the harsh Australian outdoors, the panel is encased in a corrosion-resistant black anodised aluminium frame with a tough tempered glass front, protecting the solar cells from impacts, UV degradation, and extreme weather. With MC4-style connectors and a pre-fitted cable, installation is straightforward when paired with a Redarc BCDC charger or a compatible MPPT regulator.

The compact dimensions (1430 × 670 × 35 mm) and weight (~10.4 kg) give a strong power-to-size ratio, making it suitable for roof installations on vehicles, caravans, or marine craft where space is valuable. It operates in extreme temperatures from –40°C to +85°C, ensuring reliable output on everything from cold alpine mornings to scorching outback days.

As a fixed panel, the SPRP1180B provides constant, maintenance-free power once installed, unlike portable panels that need to be set up and repositioned. Combined with Redarc’s proven electronics, it becomes part of a robust, long-lasting solar system that keeps your batteries at full charge during every adventure.
