I looked into installing a 5kW solar panel system (no battery) for the home but for me the payback was too long (about 6 years) so I have put solar panels for my home on hold.
I'll revisit this every year and when the payback becomes maybe 2 or 3 years (including battery storage) I'll give it the go ahead.
I am mindful of the way solar panel technologies are improving , and how their prices are moving , same with inverter systems , and home battery storage system. I anticipate batteries will be less than 1/2 the current price they are now.
