Your first billing period after Solar Installation

[Full Range]

Well the first 3 months went quick 

Regular monitoring gave me a good indication of how much power I’m generating 

Just a refresh I have a 6.6 kWh system x 5 Kw inverter x 20 Panels 

Highest daily generation was 39.8 kWh ( and it’s not summer yet ) with an average of approx 28 kWh 

I just received my first bill and I’m happy to report that it’s in credit 

Drum roll 

Credit $424.39 

 

At this rate I will pay off the system in no time 

System cost was $3500

An excellent result.

 

Not sure about Brissy, but August and September were very good months for solar in Sydney.

 

Cheers,

Jason.

We had a few rain / cloudy periods in Brisbane during the first billing period 

Even then the system was generating close to 20 kWh or above if a little sun came for short periods

A fairly simple way of gauging relative performance, day to day, or site to site etc, is kWh/kW.

Simply divide the kWh produced by the kW of panels installed. So in your case of your average production, 28 / 6.6 = 4.24 kWh/kW over the period.

I'm still waiting for the end of my first billing period,  but it's looking pretty good going by the Fronius data.  

8.2kW inv, (limited to 5kW export).   Since 18/11:

• PV production = 2,440 kWh  (~39 kWh/d average ,     ~65 kWh/d peak)
• Self consumption = 526 kWh
• Total consumption = 981 kWh.

Going by those numbers it means that your decision to install a solar system was justified 

As was my decision to upgrade my system from an outdated installation to a new more efficient system
