Thats about 55% ish of a south facing one, but if your out of roof space.. North facing roofs start to become attractive.

graememk wrote: » They still produce power, granted not as much as a south facing one but still a decent amount. Also if it's just a case of connecting panels into an inverter, there's not much cost there as all th hard work is done. That's also why east/west is quite favourable, you might lose some peak production at solar noon (that usually ends up exported), but gain more in the morning and evening when people are in the house
Gumbo wrote: » Depends on access etc Also depends on your invertor, and how the panels can be stringed so that one less performing panel or string doesnt effect the good performing string. For example, i have 10 panels on my front south facing roof. I am putting 6 on the rear north facing roof this month and they will be on a separate string.

The live power output from my 6kwp is 30w right now, its rainy and cloudy and 10c, but 30w is 100x reduction on 3kw I saw at this time yesterday, especially given the midday 'sun' should be at least overhead (beind the clouds). Is this the same for everyone?

I think it would be wiser for would be investors to hold off a bit.i know I will. That's not to say anyone that bought did the wrong thing. Apologies for going off thread.
