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 |

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 |
