Is This a Good Solar Deal?

  How does it compare to your other 2 quotes?

  1 installer doesn't provide the enphase inverter and other was 2 grand higher but price matched. So I am opting the one with better reviews and reputation.

  for a micro inverter system that price is quite decent, but question is do you really need micro as you can have a string system for only half that price or so with same performance, if you don't have shading it will be a big waste of money.

    TBH I don't have any shading issues. Just for better monitoring and scaling perspective I have opted for microinverters. String inverter for same configuration is costing me around 2 to 3k less.

      How likely are you to ever scale it up? 11.7kw is already a large system. I don't think you can go much bigger unless you have 3 phase or are planning an off grid system

      Only if you expect to claim warranty because an individual panel fails

      I'd look into what monitoring is available. My power distributor in Melbourne has a pretty good portal that shows net use and exports 30 minute basis (I assume it is what they use for billing). I hardly look at the app for my inverter anymore. I use the portal to compare week on week, month on month, this year vs last year etc.

      Hard to justify the ROI on that 3k

      A decent string inverter like fronius etc would end up with pretty much the same overall generation over a year as the individual micro inverters but result in a simpler/cheaper install.

      You can easily view monitoring via fronius web portal/apps, export monitoring info to sites like pvoutput to provide overall system health info.

      Without shading issues or crazy roof top configs with multiple directions etc, paying 30% more for microinveters doesn't seem like a good investment.
