Hello dirtbeard,

Don't worry about Graham's postings. Those of us who lurk on this
topic recognize him as one of the "noise" factors in the signal to
noise ratio here. He is an attention troll who seems to thrive on ANY
response he can generate. The most appropiate action is simply to
ignore his postings - as the rest have learned to do.

It's good to hear that your system is working well and contributing to
both both your independence (insulation from future energy cost
increases) and reducing your carbon footprint.

Sincerely,

Randy

I get plenty of reponses actually. My view is that simply that the best
way to use less 'grid power' is to 'ultra-insulate' which keeps wanted
warmth in and unwanted warmth out as well. This can be very effective at a
fraction of the cost of PV solar ( which really belongs off-grid at
present costs ) and the best use of solar for the average home would be
solar thermal water heating.

I'm interested to see what developments bring but current efficiencies of
around 15% for crystalline silicon and 7% for thin film plus the costs of
the panels and associated hardware are not economic unless heavily
subsidised, which means more taxes.

Define ultra insulate ok?

How much insulation you talking abt?

As much as you can fit. You can never have too much insulation. Also
consider re-use of 'grey water' and heat reclamation from it, plus
ventilation that reclaims heat too. I designed one of those over 30 yrs ago
but wasn't in a position to make them, not that people would have cared much
back then either. Now I see them on sale.

Also use superior building materials for new build. The technology is simple
and cheap unlike trying to generate GW of alleged 'green' power that's
massively costly.

This doesn't make sense. There is a cost factor
involved.
