I cant help it. Yesterday our long awaited solar pv panels were fitted and running. They come with a little screen which bluetooths what is going on.
Yesterday i couldnt help it I was watching it all the time and we have reduced our carbon footprint by 6.37 lbs. and earnt £1.79.
Anyway I woke up early this morning(always do after two days of early starts milking) and I have been obsessivly watching the screen. At 7.14 this morning I can announce that despite being overcast and cloudy we were generating 24watts. Not enough to power the lights but never mind.
I can now announce that weare producing 38w .
I know I will get used to it but it is really quite exciting. A bit like learning that Einstein got it wrong and things do travel faster than light.
Time travel anyone?

Well at that rate you will need it if you want a pot of tea!roger wrote: I can now announce that weare producing 38w .

1watt=1joule/second
You are making (max)38 joules/second
4.184joules = 1 calorie which will heat 1gm H2O by 1'c
so to boil your 1litre kettle = (approximately) 100'c x 1000mls x 4joules/40watts = 10,000s

Oh you bl**dy doom mongers. I have produced 5kwhours today. and it leaves me feeling a little bit smug. Its earning more than it would in the bank at the moment.

We had the water heating solar panels on the house we bought in 1986 and they were very effective, especially on those bright cold winter days. We'd like solar panels on the new extension so we'll be tapping you up for details Rog.

An Edwardian Windermere steam launch fitted with a kettle powered by the steam - known as a Windermere kettle - could boil a gallon of water to make tea for the gentry on board in ten seconds! OK OK the carbon footprint is no match though, but a nice way to make a cuppa.

Re: Obsessed
I'm always impressed by the solar boiling kettle at the centre for alternative technology in Wales... I think it was just two black painted radiators in double glazed boxes, with a hot coil in the kettle. About an hour per pot of tea? But usually solar is better used for lower temperature applications as you loose less energy then.
Lots of solar powered boats at http://www.electric-boat-association.org.uk/solar.htm but I don't think any of them can make a cup of tea.

Re: Obsessed
We had a solar powered boat at Chippenham a while ago, curtesy of the Gaget Show, they did a spot with 2 boats competing, solar v traditional, all the usual banter etc. Lots of fun and took all day (12 hours!) to get a tiny bit of film for the show.

Re: Obsessed
Just installed a solar hot water tubed system at home with some of my hard earned pension pot . Have had a summers worth of hot water - in a not very good summer - will see what it's like this winter.
I only really went for it since I had to revamp my old hot water boiler and tank set up. Ripped all that out and went 100% solar and as there's no central heating it's more than adequate for all my needs, and a decent pressure on the hot water.
I'd like to put up PV's too, but there's no room on the roof!
