So, I've got a bit further with my investigating and have 3 installers giving me quotes for ASHP, Bosch 9kwh hybrid, solar panels with enphase IQ8 microinverters, with solar panels still to be agreed on.
As I'm sure you know things are moving very quickly in the world of green energy tech and a big disrupter to this is the introduction of V2L/V2G EV chargers.
So, with this in mind the size of my home battery is causing me some concern. One of my installers suggested I need battery storage of 20+kwh to run an ASHP from a battery during winter.
Do I go for additional battery storage and if so how much and how easy is it to connect additional batteries to the 13.5kwh Givenergy all in one?
Grants in Scotland are as follows
ASHP max of £7500 plus £1000 from Bosch
Battery storage £1250
Solar £1250
So total of £11,000
Also available is an interest-free loan from the Scottish Government of £10,000 max repeatable over 10 years.
What I need is info as to battery storage size and solar panel type and basically any advice you can give me.
