Agree acid battery storage is not ideal,but lithium is just to expensive at the moment,but as more ex car cells become available I suspect wet storage will be gone,so may be viable to buy cheaper wet now with say 5 yr life then Upgrade ?As for generator would love to have some idea how much it would have to contribute, I still think that the right initial setup (cheap/reliable/ not overly inefficient,with VAT back and no grid connection fee MAY be viable,also I have to spend circa £2 on solar for SAPs,wasted money as it's returns would be negligible for us

Yet another figure 1/4 production in winter, I've read 1/5th and more than once 10%.. Any body got any thoughts on the idea of using a forklift charger..would it be highly inefficient? they certainly have a proven reliability record and are available at low cost

Just done above interesting but of little practice use tells me I should vat APX 7000kw yr..if only it was evenly spread !

The 5 kw day figure is the minimum we would need ,(fridge ,freezer,lighting( led) central heatinvcontrol /pump .etc.,is there a chart anywhere showing daily anticipated production per kw of panels for the winter period ?

Hello all ,read lots on the web but not any real world answers,so my question is ..new build 100 m2 bungalow 8kw solar on roof SW facing 30' pitch Estimate NEED 5KWH day ,is it viable,how much battery backup needed,how much generator input . Thought about combined controller inverter charger ..but 8kw very high,how about 8kw inverter(grid tie type) separate 3 kw (48v) inverter and 48v forklift type battery charger,all in with panels and roof mounts £3500-£4000 plus battery bank say 16 X 6v 225ah lead acid £2600. Got to put 3kw on to offset oil heating,also grid connection £3k so not a vast initial cost difference ...BUT your thoughts/experiences PLEASE !
