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 13th
Mar – 31st 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 higher 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. Although autumn is approaching the clearer skies
have lifted outputs.
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.
