Just an idea really - but for people with an East\West roof, what about a pivoting PV setup on the apex of the roof that flipped from east to west at midday?

Hi,

Yes I did think about it, the main issue is that one of the strong points of PV is its durability, ie you put them on the roof and forget about it for 25 years. The main reason is because there are no moving parts. The only weak element is the inverter which can pack up before, I advise to get a 10 years + guaranty.

East West is not that bad, I have 2.1 kWp on the East side of my roof (30 degrees pitch) and so far this year we have produced 950 kWh so I hope to make 1700 kWh in the year, I think a South facing should do about 2000kWh, the difference is not that big I think,

also you would probably fall foul of planning regulations
in most areas panels (pv and thermal) are considered permitted development but one of the conditions is that they can't extend beyond the height of the roof

Stef,

So you think that PV is still a viable choice if you do not have a south facing roof ?

My house is east/west and I have been thinking that it would'nt be worth doing !

But you may have changed my mind!  toujour!

Why not have glass panels either side the roof apex and then mount the solar panel horizontally below it.  Attach two reflective roller blinds to the glass panels and by correct timing of you roller blind you have a simple tracker system totally protected from the wind and the rain.
