Citation? It's not intuitive why that should happen -- potential short-circuits?

A certain amount of searching should be required before forcing homework onto others. You can literally google "risk of fire increases with roof-mounted solar panels" and you will see it from tons of sources including pv-magazine and others. "Citation?", "[Citation]", "Citation Needed" - these all bother me when the research is literally just copy/paste/search.

  If you are going to make a claim, you should back it up with citations. [1] [1] https://guides.lib.uw.edu/research/citations/citationwhat https://guides.lib.uw.edu/research/citations/citationwhat

    You’re putting an electrical system where there wasn’t one before. It’d be surprising if there wasn’t an increased risk. More electrical systems in your house means more risk of fire.

  Arguments presented without evidence can be dismissed without evidence. The person making a claim is the one required to back up their argument - not forcing homework on everyone who reads their unbaked argument to find evidence for your claims.

    Interesting point, but I'm going to need a citation for that.

  Interesting and useful -- thanks. My understanding is that, at least for residential installations, the city sends an inspector to check things before you're allowed to turn the system on. This would appear to avoid the first-party inspector issues identified in the article, but are the city inspectors sufficiently "strict" or should I hire my own for peace of mind?

    I saw one non-solar project where the city inspector seemed to be friends with the electrical contractor. They spent 20 minutes shooting the breeze, then the inspector did a super-fast scan of things, signed off, and left. May be best to watch the inspector do the inspection?

In Australia we have a large amount of rooftop solar. We used to fit isolation switches near the panels on the roofs so that we could de-energise as much wiring as possible in the case of a fire. The stats showed that the rooftop isolation switches shorting out was the leading cause of fires. We no longer fit them.
