    The installation just keeps getting higher. Now to add onto mine I need a load of additional equipment that was not required when my first lot of enphase inverters was installed. Also what was quoted for the labour and materials that are not the panels and inverters has almost tripled in 4 years. Have to get the roof sorted before I go ahead with it and the higher output panels and inverters mean that I would get about another 1.5kw in the same space compared to my first installation.

      Rooftop solar is the most expensive way to do it. The graph above is for utility scale systems. Roofs are always custom jobs and they’re priced accordingly. Utility scale uses racks that are all the same for an entire field.

      If rooftop was priced alone on the chart in OP, it’s be around the price of nuclear.

      To ballpark some numbers on the contractor side, I charge about $100/hr to install it now - 4 years ago that might have been $60/hr.

      Really depends on where you are, sadly.

      Where I am, a normal 6.6kw system (panels + inverter + installation) can cost as low as about $1,950usd nothing more to pay. Good for 25 years. (Higher end panels and such can go up to about $4500usd for a 6.6-7kw system)
