$20.000? I installed a 4500Wp system for €3600. How much do you get for $20k? With my system we have a net return but we don’t have AC.



The difference that I can see is the battery - a 13.5KWH battery costs ~$10k installed.

€3600 is very cheap for 4.5k installed !


Ok. Batteries seem to be a similar amount in euros here. But they are rarely used due to net metering.


In the UK we have asymmetric pricing so produced solar goes to the grid at 5p and electricity comes at 27p. At night you can buy electricity for 7p for about 5 hours. So - batteries can make sense in that you can charge them during the day and then discharge them at night. If you find that there is not enough in the battery you can put in some charge at night and then top it up during the day.
