Good morning John,

It's always good to hear from you.

I have more to say on this topic but first I'd like to know a few
brief technical details of your solar electric system, in particular -
how do your store the day's insolation for night use?

I'd also like to know the maximum solar power (Watts) you obtain from
the full noonday sun, and the amp-hour capacity of your battery bank,
and its type.

The cost of quality storage batteries for solar systems is huge and
they conk out eventually, particularly if they are worked hard with
deep discharges.

Kind regards,

Peter Bright
Tasmania

blowing in one area, it can be compensated for by windfarms at other
sites - then the expense of storing large amounts of electricity can
be avoided.
