We bought our house in 2019 with a roof-mounted 4.2kW system. The system is 13 years old now and we know we are less than a couple years away from a new roof (assessment of home inspector and some roofing contractors). We lived in the house for just 2 months before renting it out for the past 2 years while we are overseas so I don't know how efficient the panels are. The inverter (Sunny Boy SMA 7000) seemed pretty basic and wasn't connected to the network so I can't pull any stats except for what's on the small LED screen.
We plan to start a major remodel including an extension after we move back this summer. When that happens we will replace the roof.
We didn't buy the house because it has panels, but it seems a shame to just remove them and not do something with them. The panels are never shaded but they're not optimally facing the sun either. I don't want the panels back on the roof. We have over an acre and the panels face away from the neighbors towards a farm field. My thought if I am going to continue using the panels is to ground mount them, but how can I evaluate if it's worth the time and money? There are 24 175W Suntech panels up there. If I doubled the system capacity, is it a bad idea to mix old and new panels?
Thanks,
Paul
