In response to some private inquiries and finally prompted by the comment left on this blog by Tony,
Here are the specs of our Inverter Energy System and a sample of the output thus far.
The IES Installation DetailsAs noted in previous posts the inverter is a SAMIL 5200TL-D which is a Dual tracking 5kw system
It is powered by 24x CSUN 250W (250-60M) 16% efficiency panels.
These are set up as 2 arrays, 1x 11 panels and 1x 13 panels.
They are set flat on a 'flat' roof at an angle of 7° to horizontal and facing in an East-North-east direction.
The reason for the low angle was my paranoia at having a large 'wind-sail' mounted on my roof during Queensland cyclones, so wanted to minimise the wind resistance.
The main issues I see with this approach are:
- Because the panels are flat, they will rapidly accumulate sediments through lack of run-off washing-effect during rains, and thus loose maximum efficiency, hence will require regular cleaning.
- While they start power production soon after first-light, they tend to roll-off peak production somewhat earlier than I would have liked in the afternoons as the sun Westerns
They were recommended to me by a personal friend and I would equally recommend them to others.
IES Generation DetailsAs far as power generation goes, the easiest way to sum it up is with the spreadsheet I have been maintaining in the face of the hopeless reliability of all record-keeping associated with the SAMIL due to it's un-reliable internal logging, it's un-reliable LAN connectivity and the SolarPower Browser's un-reliability at recording data (see next post) ... at those times when it could actually get data from the SAMIL in a consistent fashion!
All figures are in KWh
