Hive mind, I need your wisdom. I have a 3.5kw solar array which the previous owner put in c.2011, so I have the benefit of the big FIT. Is it possible for me to add new panels without messing up the feed-in tariff? Would they need to run through a separate inverter or something? Or could I replace/upgrade the whole array?
I have a good deal at the moment as I get about 50p/unit for 50% of the units generated, but the panels are not really kicking out more than 2.9kw at very best and I would like to look at a battery and a bigger array at some point.
