Hi everyone,
Thanks for the reply, the installer fix the exposed conduit and make it look lot nicer by running it under the roof.
and yes, really happy with the 7kW system, it’s producing 49.2kWh yesterday with sunny day, it only clip for an hour in during midday 12PM to 5.9kW (the max of 20x 295W MI), and during the weekend, the system still producing around 20kWh with very cloudy day and almost no direct sun at all. not sure if it can reach the 50kWh mark or not in the midsummer 
I’m still waiting for the meter provider from enabling the solar feed-in.
Thank you for all your help everyone!!!
