Guidance for solar system please

@Screwdriva I’ve done some calculations and don’t think I’ll be generating enough to export anyway. What do you think?

I think with the pool I should estimate 19,000kWh/year given it was 14000 pre pool. And we used an extra 1000kWh in May (must be pool) 

in another thread someone said PV and battery will provide two thirds of usage so approx 12,000. My array will be 12.5 so that sounds a reasonable assumption. My generation will be higher in summer but so will my usage (circa 2000kWh per month for May, June, July, Aug, Sept). 

So, 19000 usage minus 12000 generated leaves 7000 to buy; with nothing left to sell. 

Are these calcs there or thereabouts please?
