500+

A few days ago the meter clocked up 500KW, that's about £215 back.

I've re-calculated my expected annual and monthly production using the on-line tool below, ans should produce a grand total of 2,900KW per year. Thanks for the link John (Ethical Solar).

This calculator uses location, the direction the panels face, and pitch of the roof to give an accurate estimate of average production.

I've never been so interested in the weather forecasts, hoping for a cloudless sky, it really does have a massive effect on production.  So far I've only had one day with no production, but it really was a miserable day.

When the sun does shine all day the system is producing about 7KW a day at the moment.
