    I just installed a 9.3 kW system with individual microinverters under each panel for grid stability and it is absolutely amazing how much you can power all day without threatening a massive bill at the end of the month. I still import power at night, but the power companies usually have agreements where you get credits for all wattage exported to the grid to cover your imported power at night, because both parties win in that contract.

      Do you mind sharing what price one can expect for an install that size (or similar)? I’ve been wanting to install a system like that on my house for a couple years. Now that prices on hardware are more affordable it’s becoming very tempting. I’d love to do it myself.

        It depends, $180/mo for 25 years is the agreement and it’s directly connected to the grid both ways which required additional work from the power company to inspect and approve. I think given the projections it was rated for about 25,000 kWh per year * 25 years (approaching 85% efficiency after 30 years), which is a good amount of total production for my needs. Edit: it’s worth considering what $180/mo will look like in 5 to 20 years… it will probably be significantly cheaper compared to other power sources because it’s generated locally.

          Yes the time value of money can work heavily in your favor when projecting that far out. The way the housing market is right now, I might be here for a while 🤣 Thanks for the response!

        Well, looking at these prices here listed seems like solar in US is really costly for some reason? I have a 9.8kWp system in europe, installed a year or two ago, and it cost me 12k euros. Out of that, I’ll get 2ke back in tax rebates, so 1ke for 1kwp.

        During summertime, I get 1500kWh approx in a month. I have one AC unit and two electric cars, and a 24U server rack, and can live without electricity bills some months.

        AUS here, I just got a 10kw system installed last month, cost 9.5k AUD for everything. So far monitoring the generation, I’ll be getting paid next time the bill comes around :)

      Where are you located and what was the total cost? When I last got quotes 12 years ago, it was insanely expensive ($ 70k ) .
