Solar Battery Storage

My local installer is offering 3 different brands of battery
The Tesla has 6.4kWh of storage followed by solaX with 5.8kWh and then Samsung with 3.24Kwh....all for the princely sum of £4.5k each installed.

At that sort cost it would take us at least 18 years to make it worthwhile, for the amount of electric we import each year. Are the batteries guaranteed for that long?

Hi, just joined this Forum.
Can anyone help with no standing charge with a solar panel / battery system.
I have had solar panels installed with a battery of 6.4 Kw, this allows me to use the battery power stored each day and not use any electricity while also feeding Kw's back into the grid.
I am a very low user of fuel about 7.5 kw a day on average (which comes from the battery as it charges and discharges all day and night) and will only use gas as back up heating in the winter months.
So at present I have duel fuel tariff with two daily standing charges 16.5 p and 21.9 p which over the year comes to about £135 a year.
My payment for feed in tariff should be about £240 year so would loose a chunk of this in standing charges.
Being a low user ( I estimate no electricity bill and possibly a gas bill of less than £100) should I find a no standing charge tariff.
Kind regards
Mick

If someone estimates they are using 7.5kwh a day, how likely is it that a 6.5kwh battery will supply all the electric they need during the winter months when the solar panels are producing a lot less?
I know from our system, we are lucky if we get 3 or 4 khw a day during the winter.

Hi

How likely ? .... my considered opinion ... absolutely impossible - that was easy, next question please! ....

Seriously though, the poster needs to address their energy usage and should really have done this prior to purchasing a battery system so as to understand what is really needed ... could really have done with researching, discussing and understanding the technology along with it's limitations too .... just hope it doesn't turn out to be a case of deliberate mis-selling of the capabilities and returns by an overzealous organisation ...
