Heres a bit more info on maximising your power output from your system.

1, your panels should all point due north.
2, your roof pitch should be as close to 26% pitch as possible.
3, buy a quality inverter, cheaper chinese brands usually only convert about 92% of power from your panels, whereas quality german brands convert about 98% of power, no inverter will get you 100%.
4, make sure you have a quality installation job done on ALL connections to the wiring system, you can lose power here.
5, As i understand, to get maximum efficiently from the system the panels should be wired in strings of 3, in other words multiple panels of equal amounts divided by 3, i have 39, 3 x 13.
Uneven amounts of panels produce uneven amounts of power being fed to the inverter from each string,which is not ideal.
I see lots of panels on peoples systems and they are usually not counted in numbers of 3.
Most of the installers dont seem to know this fact.
6, keep the panels clean.
I am not an electrician, but i did my homework when i invested in my quality system and hope some of these tips might be of interest to anyone interested.
