Don't get solar batteries

Screwdriva

In my experience (across 200+ installations now), there is truth on both sides of this debate. Batteries will not make much fiscal sense for those with low electricity import. But they will make quite a lot of fiscal of sense for those with high consumption.

This kWh threshold used to hover around +/- 4000kWh per annum but I'm sure the economics will continue to change, as cheap batteries and lucrative tariffs continue to be introduced to the market. 

Personally, I tend to avoid products from companies with questionable ethics and who are known to throw their hands up in the air when things go wrong, which really limits battery options. If I were to get a battery today, it would only be the Powerwall 3 but the economics just don't make sense for my level of consumption. One day....

My neighbours, who have much lower usage & smaller battery than I do but also east/west facing but no overshadowing, have not bothered doing anything to optimise the benefits of a battery.  They ended the last winter with a zero energy bill for the full year.  Never going to happen to me.  But when your annual bill has been around £3k & you are looking at under £1500.  Can't believe it was mostly an impulse buy.
