AFAIK, the list of those who have panels installed is publicly
available.

I have had two categories of callers, one wants to sell me
air-to-air heat exchangers to "make use of my generated
electricity", whilst the others claim, wrongly, that my original
installer is no longer in business, so they can offer to "take
care of" my system.

I generally send them off with a flea in their ear, unless I am
bored, in which case I attempt a little education.


We get them for our solar panels and our solar hot water tubes. They
claim for the latter that they have maintained them in the past (not
true), we have never had them maintained, and when I tell them that
they insist the systemy must need it. I always ask them why - in a
good summer, we have had free hot water for weeks. They obviously are
still working fine over ten years since we had them installed.

Solar water panels should still be usable even in overcast weather
(unlike solar PV), so even in winter you should get some benefit.

Usable, but produce very little power, could be less than 1/10 for a
short day too. A 250W panel will produce a little as 12W in the early
afternoon in current weather.
