This page gives details of the 1.8kWp system using 10 Sanyo HIT hybrid PV panels and a sunnyboy 1700 grid connect inverter. The system cost £11,300 fully installed, including grid connection charges, and the Government paid £5,400 towards it through the PV grant scheme.
Total generated to date (from 3-3-04) = 10675 kWh

Total generated in 2010 = 1259 kWh (updated weekly)

Last week total = 48 kWh, Best week so far = 70 kWh,
Best day so far = 11 kWh (weekly average amount imported = 18kWh, last week 10 kWh) Click here for 2010 Weekly kWhrs data and Cumulative totals and Monthly comparison data and Annual comparison data

The system data states that this array should produce 1600 kWhr annually
2005 generated 1619 kWhrs,
2006 generated 1640 kWhrs,
2007 generated 1619 kWhrs
2008 generated 1547 kWhrs
2009 generated 1531 kWhrs

I have signed up to the Good Energy Home Generation programme in which they will pay me 15p per unit (kWh) for ALL generated units and therefore I don't need a separate Export meter installed. (Sanyo have continued to improve their panels, each panel can now produce 210 watts instead of 180 for the same physical size) Our house has featured in 2 national magazine articles, Click on magazine name to view article • Organic Life and • New Consumer
