JAR 280W modules are designed around the principle of intelligent, efficient and high quality manufacturing. Our new 260-280W series consists entirely of Grade A Monocrystalline cells.
Highest Efficiency – Monocrystalline panels offer the highest efficiency ratings, producing the most power from the smallest of spaces and making them ideal for homes and outback applications where roof space is limited.
Positive Power Tolerance: We guarantee a 0-3% positive tolerance on electric power. This means that your solar panel will always deliver more than the rated 280W. And – most importantly – there will be no loss of electric power due to manufacturing variances.
Made under our pragmatic and innovative strategy, our panels are designed to last where others will not.
Mechanical Resilience: Our module design incorporates a reinforced frame & specialized glass coating to enable it to withstand high wind loads and/or heavy snow loads.
Weatherproof Integrity: The internal wiring within the Weatherproof System is protected by an IP65/IP67 rated junction box. This ensures the weatherproof integrity of the ‘electronics and automobile circuits’ to combat harsh coastal weather or desert sand conditions, with the ability to withstand high-pressure water jets.
Thermal Stability: Our panels have a broad range of operational temperatures – from -40°C in winter to +85°C in summer – so performance is always consistent in Arctic conditions as well as in the tropics.
