A lightweight, high‑performance solar panel weighing just 5.4 kg including fixing brackets. Its slim, non‑glass construction and integrated mounting brackets make installation fast, secure, and hassle‑free. A‑Grade Monocrystalline PERC cells deliver excellent efficiency, supported by a robust aluminium frame for added strength and a clean, modern finish. The patented low‑conductivity backplate helps regulate temperature, ensuring consistent, long‑term performance.
Ideal for motorhomes, campervans, boats, and off‑grid systems where weight, height, and aerodynamics are essential. Backed by a 10‑year warranty for complete peace of mind.
Why use a Lightweight panel?
Far lighter and easier to lift, handle, and mount than heavy glass panels.
Runs cooler with a low conductivity backplate keeps cells cooler for better sustained efficiency.
Faster installation with its integrated mounting brackets means quicker, cleaner fitting.
More durable on the move no glass to crack from vibration, flex, or impact.
Sleek, low profile design that sits closer to the surface for better aerodynamics and a cleaner look.
Reliable warranty coverage 20-year* cell warranty and 10-year** product warranty for peace of mind.

How long can I stay off grid?
A question we get asked many times. So we've created a simple calculator to give you some idea of how long your battery will last off grid. It will take into consideration any solar panels you've installed, 12v and 240v usage. Based on the information provided it will recommend a battery size and estimate the number of days use.
