08-07-11 System offline for 4 hours between 9:30 and 12:40 installer working on system
31-07-11 Power cut off for 8 hours between 13:50 and 20:05
30-09-11 Changed pay back value of .433p to include 50% of generated at 3.1p per kw
30-09-11 Changed energy cost to reflect that only 40% of generated is used, .086p =.0344, .1035=.0415, .1166=.0664
16-10-11 Shading of single panel on 5 panel string reduced string output by 90% for about 2 hours per day Oct to Mar
16-01-12 Changed Monthly percentages to reflect shading in winter months
01-03-12 Activated Optitrack Global Peak
19-03-12 De-activated Optitrack Global Peak
20-03-12 Realised if 1 panel on 5 panel string is in shade, string output drops below inverter mpp limit and causes above 90% output drop
20-03-12 If installed as 2 strings - 8 panels and 9 panels, could lose 4 panels from 9 and still within mpp, only worth about 20 p/a
26-11-13 Estimated loss of 88kw p/a combination of shading, string configuration
