Its half-cut, 16-busbar cell design and split-energy layout pack the same 250W output into a footprint about 10% smaller than standard 10BB 250W panels — a real advantage on tight RV, van, or trailer roofs.
It's rated for 2,400 Pa wind loads and 5,400 Pa snow loads, and is impact-resistant against hail up to 35mm at 97 km/h.
No — an inverter isn't needed just to charge a battery. You'll only need one if you plan to run AC appliances like a TV or refrigerator directly off the battery.
It carries a 25-year performance warranty: at least 95% of rated output after 5 years, 90% after 10 years, and 80% after 25 years.
The MEGA 250 is available in Silver or Onyx (Black) finish.
