This is my second attempt to get two 450 watt modern panels to try out before sinking a ton of money into them.
You can find Part 1 aka my attempt to buy from sungold that failed here :

The Renogy ones seem to be very similar to the sungold ones I was looking at since both advertise the same bragging points.
Specs on the Renogy ones are :
Maximum Power: 450 W
Open-Circuit Voltage (Voc): 41.25V
Optimum Operating Voltage (Vmp): 34.67 V
Optimum Operating Current (Imp): 12.98 A
Short-Circuit Current (Isc): 13.89 A
Maximum Series Fuse Rating: 25 A
Maximum System Voltage: 1500V DC (UL)
Operating Temperature: -40°F to 185°F
• 22.8% conversion efficiency provides more output per surface area.
• PERC cells capture more light to generate more electricity.
• Half-Cell tech improves shade tolerance.
• 10-Busbar tech reduces the impact of microcracks to enhance efficiency.
I'm hoping these perform decently. Anyone using these?

Ordered a few 450 watt sungold panels
Ordered a pair of the 450watt ones from Sungold last friday to try them out. Probably will be what I switch over to since my 255's are aging poorly. Bad news is they haven't shipped yet. I contacted Sungold and they said they were stuck in customs and they should be mailed out before this...
