[QUOTE="Barx, post: 529119, member: 121"] You have to consider the payback period. how much will it cost you to get the panels up there and operating? If you generate 1000kWh for the year AND self consume 100% of it, that is only a saving of about £270 (based on todays figures). Yes I know energy prices are likely to go up, but still... So, if we say it costs 5k for the install of the panels. And you save 270 quid a year, that over 18 years before you break even. In that time, you can pretty but guarantee that the inverter will need replacing at least once, so that pushes the payback out further. p.s. I know these are crude numbers but they won't be a million miles out. And these are really best outcome, as you won't self consume 100% without storage, which will cost another tidy packet. Again, this is just my opinion. I used to install a lot of PV so had to do a lot of the calcs. For me, I could neevr make battery storage viable in most cases. [/QUOTE]
