At 250 watts from a single 12-volt panel, the MEGA 250 is built for people running real loads off-grid — a cabin, a shed workshop, a liveaboard boat. Sixty-four N-Type TOPCon cells and a 1500V system rating mean it scales into larger strings without a second thought.

Why this panel

  • 16-busbar N-Type TOPCon cells reaching up to 25.1% efficiency
  • A 64-cell layout delivers a reliable 250W with 0 to +5W tolerance
  • 1500VDC maximum system voltage — room to build longer strings
  • Strong output on overcast days and through dawn and dusk
  • 3.2 mm anti-reflective tempered glass for light capture and durability
  • Rated for 5400 Pa snow and 2400 Pa wind loading
  • PID-resistant and 100% EL-inspected against microcracks
  • Tested for UV exposure, thermal cycling, and humidity freeze
  • Certified to UL 61730, IEC 61215, and CSA C22.2

Mounting and wiring

  • Anodized aluminum frame — lightweight, rigid, corrosion-resistant
  • Fourteen pre-drilled holes for Z-brackets, tilt mounts, pole, or ground racking
  • Four-foot 12 AWG MC4 leads pre-attached
  • IP68-rated junction box — a step above the IP67 used on the smaller MEGA panels
  • Compatible with both on-grid and off-grid inverters

Warranty

  • 25-year power output warranty
  • 10-year workmanship warranty
