If you are considering solar PV, your first step is to find out what kind of system will meet your needs. Our solar calculator will give you a good indication of the size and cost of a solar PV system for your home and/or business. A simple three step process will estimate what size solar array will suit your needs. Simply enter your average power bill usage (kWh), the price you pay for each unit of electricity, and the region you live in.
SunCalc is a great tool to understand the movement of the sun on any given day. Use SunCalc to identify the section of your roof that captures the most sunlight and use this as an indication of the best placement of a solar array in your location. By installing solar panels in the sunniest spot on your roof you will be able to make the most of your solar system. Simply select your location, adjust the time of year, and use the slider to see how the sun moves across your property.
Show SunCalc and select your location
Enter in you address and see the sun movement and sunlight phases during the given day.

Want to make the most of your surplus electricity? There are several energy providers that provide a buyback scheme for surplus energy generated by solar systems, including Meridian, Contact Energy, Mercury and Genesis. Meridian and Contact currently provide the best payback rates.
Whilst buyback rates are an attractive prospect, they should largely be considered as an afterthought rather than be the basis on which the decision to install a solar system is made. The more power you consume at time of generation (during the day), the more you can save. By slightly altering your usage behaviour, by setting appliance timers to run during the day for example, your daytime base load will increase. This increase in self-consumption results in fewer units of electricity being purchased from the grid and significantly decreases your energy bill. If sized correctly your system can allow you to become virtually self-sufficient!
There are many factors which impact the return on investment (ROI) of a solar PV system. However when looking at the overall ROI of installing solar PV on your home there are two important points which should be considered –
One unit of solar electricity can be considered as either:
As a majority of buy-back rates are currently of lower value than the average retail rate for a unit of electricity, self-consumption presents a favourable advantage to increasing your ROI. Adding to this, if a unit is self-consumed the consumer does not have to purchase this unit from their energy retailer at full retail price.
As solar PV is now increasingly affordable the payback period (the time it takes for your system to recover its total upfront cost) for solar PV now commonly sits around 7-10 years. Having paid for itself, any energy generated by your solar system after this period can be viewed from one perspective as ‘free’ power, leaving you with upwards of 15 years of electricity being generated for free!
