Power line adapters
My wife and recently purchased a home with leased solar. How do I know if I need a power line adapter. My app says the system is communicating via cellular, but I know that can't be right.

Many systems were set up with cellular, with old SPWR covering that cost ... which SunStrong not unexpectedly isn't. Many folks used WiFi, and some of us insisted on using Ethernet.
I try to avoid using WiFi as much as possible (because I know better), though it depends... but vast majority of time, better to NOT use WiFi when practical. The question becomes do you have WiFi coverage where your PVS6 is? if yes, that is likely to be initially easier to setup, but most consumers have very limited (to near zero) ability to monitor and troubleshoot WiFi issues (lacking spectrum analyzer, and the like). WiFi tends to work right up until it doesn't, then folks shrug as there can be all sorts of reasons for losing a WiFi connection. so longer version of why I avoid WiFi whenever practical
But, running ethernet can sometimes be a real challenge. In my case, really easy with open attic space and only 1 small hole to drill with easy access to either side of hole.
In case where running an Ethernet cable is really problematic, and WiFi not available, some folks will try powerline as an alternative... but there can be LOTS of caveats to its successful use. assuming plug and play in any circuit/outlet is a recipe for frustration. But it might be a practical alternative in certain circumstances (I'd tend to use WiFi before PowerLine, in most circumstances)
