I thought I read somewhere that, due to the Government reducing the
feed-in tariff soon, all available PV installation capacity was taken
up. Or did I mis-interpret that? I have no intention of using it.
But today I received yet another invitation to call for a no-charge
no-commitment consultation. This one from Sunuser, of Leeds, and I am in
East Anglia, so I am really sure to use them as a local supplier. Maybe
I should take them up on it, just to waste their time!

The danger is that if they don't reduce the FIT for PV systems they
would have to find more money from somewhere.

But today I received yet another invitation to call for a no-charge
no-commitment consultation.

Got a card with the post this morning "Help reduce our carbon
footprint and be rewarded with FREE electricity and an income of up
to £60,000 for 25 years!"

So many weasel words:

"our carbon footprint". Whose? Society has a whole or this company?

"FREE electricity". Well if you don't count the capital cost...

"income of up to £60,000 for 25 years". "For", doesn't that imply
£60,000/annum for 25 years? Rather than the reality of up to £60,000
*over* 25 years.

They also wanted age group, but only 35-60 and 60+ and number of
occupants in the household. Looking to target the elderly on their
own or just a couple? Also the name of the company "Green Deal Solar"
is trying to link in with the governments "Green Deal" that should
appear next autumn. Based in Paisley so only 130 odd miles away.

Around £1,500 so far, since 21 April thanks very much for your
concern.
There are some crooks and exaggerations out there mind.
I was looking at a PV advert in the DM yesterday. There was some
definitely dodgy claims in it.
The future of the industry is going to depend on how much installation
costs fall.

They are running at 7-800volts in strong sunlight, I haven't dared
touch them to find out.
As they are on a bungalow it would not be a great problem to clean
them if they did need it.
Night, torch, water, brush with long handle.

There is no algae/lichen/moss on the south facing aspect of our slate
roof...

Sheltered spots on the north facing has occasional and small spots of
lichen. And this is natural slate so a compartively rough surface
compared to glass.

mmm as per Messrs Pilkington?
"The first stage of the cleaning process is "photocatalytic". In this
stage the coating reacts with daylight to break down organic dirt.

The second stage is "hydrophilic". Here, instead of forming droplets,
rainwater hits the glass and spreads evenly, running off in a "sheet"
and taking the loosened dirt with it, also drying quickly without
leaving streaks."

which I think means...you have to wait both for a sunny day (top
loosen the crud) AND til a rainy day before it washes any of the crud
off "itself"?

There is an installation near me where one of the panels is
directly beneath the TV aerial. Bird droppings were visible after
only a few days, so it will be interesting to see how it fares.

rainwater hits the glass and spreads evenly, running off in a "sheet"

which I think means...you have to wait both for a sunny day (top
loosen the crud) AND til a rainy day before it washes any of the crud
off "itself"?

Well whatever it is, they have remained clean to date.

There is an installation near me where one of the panels is
directly beneath the TV aerial. Bird droppings were visible after
only a few days, so it will be interesting to see how it fares.

Assuming that the panels also re-radiate some of the heat, the birds
probably love that spot!

Exactly so.

Don't PV panels get quite hot in sunshine, hotter than a glass
conservatory roof I would have thought. Maybe too hot for
algae/lichen/moss to survive on for long?

They are running at 7-800volts in strong sunlight, I haven't dared
touch them to find out.
As they are on a bungalow it would not be a great problem to clean
them if they did need it.
Night, torch, water, brush with long handle.

mmm seems trivial but that didn't work easily or brilliantly on my
conservatory roof.....in the daytime...
It's quite well stuck on - has to be to survive weeks of rain and snow
etc etc

They are supposedly self cleaning. We'll see.
