Solar Panels Geelong: All you need to know!

Geelong High School Solar Panel Installation Project

Geelong, located just west of Melbourne, is a good place for installing a solar PV system. Additionally, with electricity rates rising, the price of solar PV falling, and up-front rebates available through the Federal Solar Credits scheme, now is a great time to find the best solar power deals in Geelong.

Advantages of having a solar power system in Geelong

Benefitting financially from Geelong’s sun irradiance

Geelong rooftops see an annual average around 3.7 hours of sun per day at a typical level of efficiency. In the below table we have calculated (peak hours x kW system size) the output of some typical residential solar system sizes.

1.5kW 5.6kWh
2kW 7.4kWh
3kW 11.1kWh
4kW 14.8kWh
5kW 18.5kWh

Power consumption vs solar PV generation

All grid-connected Geelong residents may benefit from having a solar PV system installed in two ways:

Avoiding purchase of electricity from the power grid/electricity retailers by consuming solar power as it is generated (“self-consumption”). For this to work, the premises with the system must be occupied, or the appliances scheduled to run during the daytime hours when the system is producing power. When solar power is self-consumed, its value to the user is effectively equivalent to that of electricity from the grid.

Earning a Feed-in Tariff for surplus energy exported back to the grid – if the system is approved for export by the local Distributed Network Service Provider (DNSP) then exported energy can be sold at a minimum of 9.9c per kWh as per the mandatory minimum in Victoria. Some retailers are offering better feed-in-tariff rates.  

In order to optimise the ROI for your solar panel investment, you must first understand how much power your home or business uses on a daily basis. Energy use depends on the number of occupants and energy usage patterns. However, as a basic example, the average 3-person home uses an annual average of about 20kWh per day. The average home’s electricity consumption will be mostly offset by the output from a 5kW solar power system. As feed in tariffs are generally lower than your electricity rates, oversizing your solar panel system to your daytime energy use will result in lowering your return on investment.

Up-front State and Federal Government Solar Rebates for Geelong

The next step in finding the best solar PV system deals in Geelong is educate yourself about your eligibility for Federal and State incentive schemes. Victorian residents are eligible for both a Federal government ‘rebate’ and Victoria’s Solar Incentive Scheme.

The amount of the Solar Rebate available to someone who has a solar PV system installed is based on the number of sun-hours that the installation location can be expected to receive. Under the Federal Government’s Solar Credit Scheme, households are granted Renwable Energy Certificates (RECs, also known as Small-scale Technology Certificates or STCs). How many STCs are granted depends on location, system size, and the certificate price agreed on between the customer and solar installer. STC prices rise and fall with supply and demand, but  solar installation companies can set a rate in deals with individual customers during negotiations. (STC prices are disclosed in Solar Choice’s Solar Quote Comparison sheets.)

Solar System Size STC Rebate*
1.5kW Solar System $803
3kW Solar System $1643
5kW Solar System $2774
10kW Solar System $5548

Solar Victoria is the body the state government has setup manage the delivery of the Victorian Government’s Solar Home Program – which offers an additional rebate to the federal program to eligible households. If eligible, your rebate could be as high as $1,888 for solar panels and $4,838 for solar batteries. This rebate is in addition to the federal solar rebate, taking eligible Victorians into a ‘no brainer’ decision to go solar.

  1. The technology of solar power energy is advancing at a very fast pace and the costs pertaining to its installation are decreasing due to intense market competition. The demand for electricity in the world continues to increase, therefore optimization of generators growth in the world is deemed necessary in order to establish a balance between the electricity supply and the required amount of demand. This fact makes many people feel interest to conduct research about it, as the example in this article, (link removed) ,they conduct a research to increase production and efficiency of electrical energy. The solar radiation energy was chosen using the combination of solar cells and Thermoelectric Generator.
