When we started planning a new build, battery was a "nice to have" -- now - with power outages last year, flexible off peak tariffs, and a bit of "go for it" attitude, I think we'll install a decent battery with intention of using the in summer as power bank from solar PV, and when seasons go to autumn, winter and spring, use it as an off-peak storage to be released during day.
Thanks for the replies. The octopus tariff looks interesting, however it could be pulled at any point, so basing what is an investment decision on one tariff is risky.
Definitely food for thought though.
Have you done research ? It's not one tariff there's a handful of good options across a few companies - with a few even better options currently coming to market - if your in the south east today there's a glut of renewable predicted they want rid of to grid balance so there is actually a free power hour this afternoon
Yes they could be pulled but equally electric prices could go through the roof.
My maths was working pre electric prices going mental but then installs were cheaper (lots)than the last 18 months or so.
Unless you want to make a hobby out of scanning weather forecasts and working out when to put the washing on and cook the roast etc you'll probably lose 30-50% of your solar generation unless you have a home battery, expecially if you are out during the day. Batteries also let you make use of time based tarriffs in winter.
