Your could have been worse is my, this is perfect

I needs this
This is me

Individuals don't usually have the spare cash for this, so HA's, local authority etc need to pick up the slack :-)

I work for a housing association that's looking at putting these on as many roofs as possible within budget and puts solar on all new builds
2019 we were looking at putting solar on every available roof space but the storage capacity wasn't there, nor was the billing info available, working on it

More money and more electric
Tbh we need to be putting solar on more roofs and finding better battery storage or putting water tanks back in that act as heat storage

True but its the cost to buy them, plus as well you've then got to deal with the mould and damp that builds up
