Does your controller find multiple power points? With those voltage specs it looks like the new panel would have to parallel to the other 2 that are in series to stay in spec for what the controller can handle.
The second panel you are looking at has a closer Vmpp to 2x your existing panels. Closer MPPs means the system will make better power across the different spec panels because each can run closer to its optimum voltage when run together.

Hi Tech, why would l need to run them in series? With the two 135'sin series giving me a nominal 24 VDC plus a 245Watt additional panel (nominal 24 VDC), hooked in series would give me 48 vdc, NO.?
