BDPV PV Website

27 Dec 2011: I recently discovered the website http://www.bdpv.com/  which is a French site, providing a geographical database of PV systems installed all over Europe.  Each user is trusted to supply their own data for each month, and have that compared with others near them, and with the classic PVGIS calculation for that same Lat, Long, Orientation and Roofpitch.


Above is the display for my PV system for the most recent year (2011) with an estimate for the final figure for December 2011 (which is already well ahead of the previous year. The chart shows comparisons with the previous two years.
 It is easy to register with BDPV and there seems no charge for using it. I am surprised at how many are using it already, including quite a lot within a short distance of my home.
