Hi @Bushwalk, I think it’s best to ignore those ads completely. $6.4k is probably at the cheaper end of what you’d want to consider, cheaper than that and you’re getting into the too good to be true realm. You’ve got to cut corners somewhere in order to get those really low prices.
This quote looks decent. Can you get a quote with LG, or REC panels, or any other panels on this top 10 list here, just to compare:
With the Tigo, did you mean to say $481 extra? It would depend on your roof as to whether it’s worth it. Probably only worth taking a look at if you have any sort of shading issues.
As we always say, the really important element is the company you buy from. Make sure you are confident and happy with them, and if you’re not 100% sure, make sure you get quotes from a few different ones. Also try and get a quote from a local electrician, especial if you know one that is recommended.
