I just had a phone call from some company claiming that after fitting panels on my roof, which faces east and west with the ridge running north south, I would be totally independant for my hot water and electricity as these brilliant new panels heat the water and produce enough electricity even when the sun don't shine.

All they need is daylight.

I told him he was talking the biggest load of rubbish I'd ever heard and if his system was so good why are all the council houses not fitting them.

I told him he was welcome to come and waste his company's time getting a surveyor to come and survey my house but he will just say what the previous surveyors said.

Why did they even book a survey for me to come here?

Your house is totally unsuitable for solar panels.

He hung up on me.

solar pv or solar hotwater?

You tell me.

I don't believe it. In Scotland, I've forgotten what the sun looks like.

A friend of ours lives in Scotland and has had solar pv installed on a West facing roof - he's hit his target of 2650kwh in less than 6 months, of course the least productive months are to come but he will over achieve his estimates by at least 10%. Yes, it generates less than a South facing roof in the South of the UK but it does still work.

Ours is on the England Scotland border, 51 degrees East and we've generated 3533 kwh since 5th November last year. Not bad for somewhere that doesn't get the sun.

Haha some would fall for it. dont know how you would manage in the winter. Probably work if you had one low energy light bulb running. soem people do have there panels split into 2 half one east and one west and seem to get descent outputs but the cost. WOW. curious about your hot water though. to have both water and PV your roof would need to be massive.

... and the low energy bulb only ran during the daytime ..... they may also be advocating heating the hot water using an immersion heater or installing combined pv/thermal panels .... also remember that an E/W split system effectively doubles the roof area which panels could be installed on, so maybe the roof wouldn't need to be that large afterall ....
