Instant Quote

Get an instant quote for a grid connected solar system. If you already know the size that you want, please select the "System Size" option.

We can also calculate an appropriate system for you based on your electricity bill and usage data. If you have hour bill handy please provide the required "Meter Reading(s)", otherwise select "Bill Average". Please note that we have to make some assumptions in the latter case.

System Size

Roof

What type of roof do you have (to mount the solar panels onto)?

 
 
 

Meter Box

Is the meter box attached to the same building?

 
 

Your Electricity Usage

To calculate an appropriate grid connect solar system we need to look at your energy needs. Please use a typical and recent electricity bill to fill in this form, and if possible also submit that electricity bill to us (using the upload function on next page).

How much is your average electricity bill (in AUD)?
What is the average billing period (in days)?

Electricity Account

Is this a residential or a business account?
Account Type
 
 
Are you registered for GST?
 

Connection Type

Is this a Single Phase or a Multi-Phase connection?
Connection Type info iconCount the number of House Service Fuses in your meter box (there will be one fuse per phase). Most service fuse covers are black, but some are transparent or grey.
Some service fuses have red cables go in and out on the side (visible to you) while others have cable entries on the back (invisible to you).
NEVER pull out a house service fuse; in fact it should have been tamper-sealed by your electricity provider.
 
 
 
 
Do you have a time of use meter?
Are you billed with time of use tariffs?

How much do you pay per kilowatt/hour (in ¢)?

Appliances / Loads

If you have an electric hot water system, please indicate the number of people in your household.

Which of the following do you do/run regularly during the day?

 
 
 
 
 
 

Optimise - Be Battery Ready

This calculator built a minimum export solar system based on your average consumption.We suggest, however, that you add more panels:

  1. to offset intermittent peak demands, and/or
  2. to be battery ready info icon Integrate batteries to increase self consumption


System Summary

Based on the above data we recommend a kW solar system with the following components:



Maximise your Savings

The above system has the potential to save you up to $ over 20 years.* You could try to find a net Feed-in Tariff to maximise your savings. Generally, it is much better to consume than it is to export, though.
Find Energy Retailers with a FiT.

The projected savings over 20 years assume that the above tariff never changes, which is unlikely (it is predicted to go up - increasing your savings even more).

Your energy usage is very low. Could you be living off the grid?

* Additional charges may apply depending on your circumstances, e.g. roof shape, meter box upgrade, remote earth fault alarm, CT-Meter upgrade/install The quote includes installation and a government rebate of $ STCs (@ $34 each).

** The quoted price does not include cost for mounting frames and installation. Site inspection required.

*** Tall buildings and steep roofs may require extra safety measures that are not included in this quote. Site inspection required.

**** Distant meter boxes may require trenching work. Site inspection required.


Disclaimer

This grid connect solar system and savings calculator is the result of 32 years in the solar industry. While not every possibility can be covered, we believe the calculator returns an adequate solar system based on your needs.

The graphs display average figures. Energy usage is usually more volatile; also the actual energy output of a solar system rarely looks this even. Factors that influence the performance include (but are not limited to):

  • Weather (sunshine or cloudy)
  • Time of year (summer or winter)
  • Shading

The savings calculation assumes a moderate consumer price index (CPI) of 2.5% and decreasing panel efficiency of 1% per year. The actual electricity price increases over the last few years were significantly higher. If prices continue to go up as they have in the past your savings will even be higher.
