Our read of the datasheet

The Infinity RT 475 W is the top bin of DMEGC's 455 W to 475 W all-black dual-glass series. Its 23.8% efficiency is among the highest in this group, and the 1762 x 1134 mm footprint is the common size for current rooftop panels.

Both faces are 2 mm heat-strengthened glass, which makes it the heaviest panel here at 24.0 kg, worth checking on older or lightweight roof structures. The temperature coefficient of -0.29%/°C is typical of current N-type panels. Operating current is 14.99 A at maximum power, so the inverter needs enough MPPT current headroom.

The warranties are 25 years on the product and 30 years on power, with 87.4% of rated output guaranteed after 30 years, based on no more than 1% loss in year one and 0.4% a year after that. Power sorting is positive only, at 0 to +3%.

We have not tested this panel. This summary follows from the manufacturer's published specifications, checked 23 September 2026.

Strengths

  • 23.8% efficiency at 475 W
  • 25-year product and 30-year power warranty
  • Positive-only power sorting (0 to +3%)
  • Hail class HW3 and 5400 Pa front test load listed

Things to check

  • Heaviest panel here at 24.0 kg
  • High operating current (14.99 A) needs inverter MPPT headroom
