RENERGY RNG-100D-SS vs RNG-100D

[Solar Cowboy]

I recently purchased a new unused Renergy 400w solar kit. (4) 100w panels w/controller. They bought it on Amazon. Panels are model RNG-100D. I want to upgrade to 800watt system with 4 more 100w panels but I cant find RNG-100D panels. Like they were discontinued or something. Whats out there is RNG100D-SS which have
slighty specs. Can I use the RNG100D-SS in conjunction with my RNG100D?

What is the spec of the solar charge controller?
The difference between the two panels is about 8%.
You can try different combinations to see what the end result will be, but you have to be sure the Voc will not exceed the max PV input Voltage spec.
You can study the link below about mixing panels.
