The villain known as "the solar panel man" is fitting panels this week
for which I truly appreciate all your subsidy contributions...

I'm now trying to get my head around Air conditioning to make sensible
use of generated power... Reason being that the upstairs living areas
of our house get intolerably hot during the summer (we have large
amounts of loft insulation but it still gets up to high 20's to low 30's
during a prolonged warm spell)

I'm looking at some form of ducted air-con with 4 or possibly 5 outlets
into the upstairs rooms. (Bedrooms downstairs are well insulated thanks
to UFH and they are half underground so always delightfully cool, never
seen them above 21 degrees ever)

Am I right in thinking if a 10kW unit has an EER rating of 3.2 (for
example) the actual power required to run at maximum rating is 10 / 3.2
i.e. 3.13kw ?

Also, an Inverter modulates compressor load depending on how much
cooling/heating is required?

And... that a heatpump feature means additional heating is available
should it ever be required for a speedy warm up of a chilly room?

Also for a ducted system there is only one control which again I guess
would be situated in the hottest part of the house and is it possible to
have some form of thermostatic vent control in the individual rooms?

Finally... How much of AC can be done DIY? I'm presuming the pipes from
head to compressor would need to be made (flared) on-site and the system
charged by a man with a cylinder?

It would be nice to think the Solar PV being generated is actually
making our living area liveable especially for the dog!
