I don't mind servicing older, existing systems. It is fun to work with the older components, like APT power panels, SW inverters, and Trimetric monitors. I will frequently bust out the solder gun and repair old modules and components. On most of these systems, I will recommend upgrading some components, and will replace unprotected wiring. If something is a hazard, then I will repair it. I find that grounding systems tend to be the weakest link, and generally need to be replaced or repaired. Overall, I have been lucky to have reasonable customers who want their systems to be safe. Well, there was that one guy who was running his genny with the gas cap off, which started a grass fire just as I was pulling up....

We don't even try to work with what's there; everything comes off the wall, and we rebuild the whole system using any decent parts that can be reused. Most customers report much more reliable operation after, but you still can't find everything. I try to stay out of the premises distribution wiring, and keep the work just to the PV, batteries, inverter, etc. This keeps it clear what you're responsible for, and what you're not. If pulling a permit, I write it up to specifically exclude distribution wiring. These days, I only take them on, if they are essentially buying a new system (batteries, more PV, inverter, or charge controller upgrade.....) I often sell them a whole new power board, and offer a trade-in on their old usable equipment. Even reusing old PV is getting harder these days (rewiring an old array of 50 watt modules, often just isn't worth the time) Unless you've done several of these, I'd stay clear of them. There are easier ways to make a living. GridTie has fewer call backs, by far. R.
