What size system?

We’ll take the confusion out of choosing a system.

No matter what your house size, family size or budget, there’s a FreeSolar system to suit your needs.  The size of your FreeSolar system will depend on the physical unshaded area available on your roof, your budget, and what portion of your power consumption you wish to generate. Our highly-knowledgable customer service staff are on hand to guide you through the process, however, you can get a good idea by following 3 easy steps.

1. Find your last power bill

All of the information you need to calculate your average daily usage is on your power bill.  You could even take a look at a few bills, as power usage will vary from season to season.

2. Look for the kW hours per day usage figure.

This is normally located next to a usage graph on the back of your bill. This is a guide to how much electricity you consume in a day, and therefore the average amount of power your FreeSolar system needs to produce to cover all of your power needs.  Remember, that any reduction in your power bills is good, so if you are budget restricted, start small and add more panels as you can afford them.

3. Check the table below.

Now that you know how much power you use in an average day, check the table below to compare this figure against the number in the “Multiplier Effect” column. This is a guide to choosing the most suitable system to match your existing power consumption habits. If you want to sell even more power back to the grid, then choose a larger system.

*  Calculations are estimates for Queensland only. Actual production may vary.  Estimates are based on the following:
Average production of 4.2kW hours per 1kW of Solar PV Panels as per Clean Energy Council guidelines for South-East Queensland.
 44 cents is the minimum Feed-in Tariff in Queensland.  Your individual electricity retailer may offer more than 44 cents enabling you to save even more.  Please discuss your agreement with your individual electricity retailer.

4. Space Requirements:

Another factor you will need to consider is the size of your roof, remembering that the ideal roof aspect is North (North-west to North-east is ok).  The following is an indication on the space required.  These are estimates only and should be used as a guide.  The actual configuration of the panels will depend on your roof shape, and our installers will advise you at the time of installation.  The system should clear any capping and edges by 300mm.
