DES's commercial system in Ulverstone has just completed a 12 month cycle and its performance is now our best performing system in Tasmania
It has completed the year with 46510 kWh generated from a 30 kW system
that equates to 4.25 kWh per kW installed (most systems perform between 3.5 and 3.9kWh per kW installed. 
this customer has used onsite 41248 kWh saving thousands of $$$
they only exported 5262 kWh this gives them a 89% self consumption rate (the higher the rate the bigger the savings)

To work your solar systems performance out to compare:
total annual kWh generated divided by 365 then divided by your system size (panel size NOT inverter size) 
eg. if you have a 4 kW system (16 x 250w panels)

5500 kWh generated / 365 =  15.06 kWh per day then / 4 = 3.76 kWh per kW installed

DO NOT divide it by the inverter size as this is NOT your system size (if you have 3kW of panels attached to a 5kW inverter you only have a 3kW system not a 5kW system as the system will only ever generate up to 3kW

DES has completed a huge 29.9kW micro inverter solar system on the Bass Strait Maritime Centre in Devonport.
Some of the main reasons they went with Micro inverters were:
Safety - low voltage DC less than 40VDC
future expansion at any stage
full monitoring 
controllable so panels can be switched off at any stage - by per panel
