As per prevous reports, households are identified by initials – number
of panels – tilt angle - orientation (e.g. SP-6-37-N = Simon Pockley - 6 panels
- 37o – North). [NB. To
print - use Landscape format]. Graph #1 shows system outputs beside the number of
generating hours for the last fortnight.
Graph #1. Comparison of system
performance 28th Feb – 13th
Mar 2009 (ranked by tilt angle)
Graph #2 plots the output per panel, for the last fortnight, against tilt angle. I’m yet to measure the tilt angle for JW. This fortnight output was significantly worse than the last fortnight (see graph 3).
Graph #2.
Tilt angle compared with KWh outputs for the last fortnight followed by previous
fortnight values
The following graph compares the output per panel for each system since
13th July 2008. Autumn is now approaching and as days shorten we can
expect a further decline in output
Graph #3.
Comparison of systems shows total KWh generated.
The following graph
aligns all the readings (sequenced left to right) with tilt angles. I’m looking
for a better way to display the changes through season.
Graph #4.
Comparison of all KWh readings for each system ranked left to right by time and
tilt angle.
