Dull in November 2008, but panels still fly

NOVEMBER 2008 was not the sunniest of Novembers we’ve had, but the 15 Sanyo panels on the roof continue to deliver bijli (‘lectricity) to the house and to the UK’s National Grid.

Here’s a screen grab of what happened in November 2008, and because the system has run for not too far short of two years now, we can contrast this with November 2007.   Was the 30th of November so dull that no light shone from the south? Surely not.

Hang on – according to the November 2007 screengrab below, there wasn’t a 30th of November last year either. Perhaps there is a bug in the Fronius software?

Anyway, facts are facts. Since the system first started, we have been in credit with our electricity supplier – it owes money. And the National Grid scheme pays cash for the contribution the panels make. It is a daft idea installing panels unless you really go for it – it’s obvious that you have to place them in the right place, and polysilicon is at a premium right now, so they still remain expensive.

Perhaps with the panic in the semiconductor market, there will be more polysilicon available. Undercapacity fabrication plants (fabs) are very expensive to run.  It’s a crying shame folk in places not on our latitude but which see the photonics more can’t have more of these panels on their roofs – futile green gestures are not nearly enough to make a difference.
