Required. One house with existing PV installation.

BIG ex computer machine room UPS. The bigger it is the more money you
can scam.

As many old or near dead car batteries as you can muster.

Hook up the UPS to run the house and generate as much as it can in the
day. So you the UPS, the batteries and the solar panels are all sending
leccy back to the grid at 45p a unit.

At night run the house and charge the batteries on electricity bought at
5p a unit off peak. Or a pair of croc clips upstream of the meter
altogether.


Then go out and gloat at the pub that you have ripped off the country to
the tune of several rounds every day. Whilst looking smug and green to
the unwashed bearded be-sandalled greenie in the Public bar. If anyone
accosts you, tell them you name is 'harry'.

Simples!
