Camecs mono-crystalline solar panel range uses only A-Grade solar cells throughout ensuring the panels will effectively generate as much current as possible with the available sunlight supplied. All solar cells are individually tested to ensure they meet A-Grade specifications before being assembled into a final panel. This way we can guarantee that the power rating of the panel is true and not overstated. All panels feature toughened glass to protect the cells even under the most harsh of RV environments and with thousands of these panels already installed on RVs throughout Australia and New Zealand, you can be assured of Camecs commitment to quality.
