2. NeON R has an one of the best temperature co-efficient, meaning on hot days the panels perform better than NeON 2 and much better than standard panels.
3. The degradation rate of the NeON R is less than the NeON 2 over 25 years and much less than standard panels.
4. The NeON 2 has 12 wire thin busbars and the NeON R has no busbars on the front of the panels. Both panels have an aestheticallypleasing appearance.
