I think the best $ wise setup more solar panels on the feed in tarrif (oversize into your inverter)
I've been looking at adding more panels. What do you mean by this? (genuine question)
even if your inverter is xkw, doesn't mean you have to have x kw of panels. the inverter has a max v input. dont exceed that and you're apples.
eg, in qld we are limited to 5kw feed in. I have 8kw panels going into a 5kw inverter. in full sun the inverter clips. but on a sunny day I am hitting 5kw at 930 am and staying there to 3.30pm. (whereas 5kw of panels might mean I only just hit 5kw if the sun is directly overhead)
there are many factors like roof tilt, shade, cloud etc that detract from your panels output. more panels means more chance of maximising your inverter and your generous feed in rate (if hooked up) if you have extra it just clips .
I can produce over 45kw a day, which is $20. If conditions aren't ideal, you still put out much better figures. You can even put 10kw into a 5kw inverter. (you have to have the panels set up right, and certain inverters have more favourable specs) Known as overclocking in some circles. does not void warranty of inverter, as inputs are max v. Taken to the extremes, your inverter output resembles more of a square curve than a bell curve. I generate approx 5000 dollars a year worth of power
In any case, in my situation i sell power at 44 cents and my conventional HWS connected to a tarrif is 13 cents an hour.
