I think we may be straying off topic in this thread though!
Ah I wouldnt worry too much
While I can understand the whole no battery grid connected thing, I do have to question how many days in the year a grid connected system would acutally be viable in the UK and how much usable power and what the system would actually be powering during the day?
Is it more the case of supplying back into the grid rather than actually powering the properties that its installed in ??
It would really frustrate me having +1kw system sat on the roof and then after a sunny day having to use grid power because I havent been able to store any of the energy that the panels sucked up during the day
Not all batteries require topping up
I have just come home today from comissioning 4 off 1.3kW grid linked PV sytems on a group of social houses for rent, which would not have been installed by the housing association if they had involved all the hassle of batteries
The above sits very un-easy on me, and I have to wonder if its more a case of a certain .gov making it look like they are all green and clean, the fact that its not exactly that useful for the punters is irrelevant.
It would be interesting to know how many installs your doing for .gov or similar, compared to private individuals that are just plain grid connects with no storage ?
