Solar Panels

Solar PV

GV Community Energy is a leader in the design and installation of solar PV to suit both domestic and commercial purposes.


Is my home or business suitable for solar power?

Installing solar panels on a north facing roof is ideal, however east and west is also possible, (resulting in approx. 15% loss of production). The orientation of the panels will have a greater effect on the solar power produced than the angle they are tilted at. Most homes have a roof pitch of 20 to 30 degrees. If your roof slope is flat or the pitch is low (less than 10%), a tilt frame may be recommended by the installer and this cost would be itemised in your quote.


What size solar PV system do I need and how much will I save?

This is determined by how much power your household uses during the day, and in particular during the peak solar generating hours of 10am and 4pm. Installing solar PV is most attractive in situations where most electricity is used during the day.


The following factors can greatly influence reduced energy consumption on your power bill once a solar PV system is installed:

  • when power is used within the home - mostly during daylight hours (solar power) or outside daylight hours (grid electricity)

  • number of people living in the house

  • size of the home and how energy efficient it is,( eg. are there gaps and leaks where heat/cool air can escape)

  • appliances used in the home,(eg. plasma TVs will use much more electricity than LCDs; electric hot water systems vs gas)


Will I receive a government solar rebate?

The Australian Government solar rebate scheme ceased on 1 January 2013, however Small Scale Technology Certificates (STCs) will apply when you purchase a solar PV system. This is a type of carbon trading, free market mechanism that reduces the cost of renewable energy. One STC is equivalent to 1MWhr of electricity generated by your solar PV system. The price of STCs changes according to market conditions. When negotiating solar PV package prices with our suppliers, GV Community Energy obtains a fixed price for these STCs and this will be detailed in your quote. STCs applicable in the current pricing package equate to discounts of between $470 and $5,493, depending on the size of system purchased.


Solar “Zones” explained

Zones are determined by the Federal government based on your postcode and will relate to how many STCs you will receive for your solar PV purchase. 

How much electricity will a solar power system produce?

How much will I be paid for an excess solar power produced?

The ‘feed-in tariff’ offers a minimum of 5 cents per kWh for excess electricity fed back into the grid. All electricity retailers with more than 5,000 customers must offer a minimum 5c per kWh for excess electricity fed into the grid, and they may offer different packages and terms and conditions. Some electricity retailers may offer a higher rate but are not obligated to do so.

The rate for the feed-in tariff is currently under review by the Essential Services Commission and may change in 2017.


Will I need a Smart Meter?

Households installing solar PV will require a Smart Meter so that the power in and out of your home can be accurately measured. Connection of your Smart Meter will be organised by your electricity distributor. Solar customers will be charged approximately $340 (Powercor) or $240 (SP AusNet) for the connection of Smart Meters, where a Smart Meter has not already been connected as part of the National roll out of Smart Meters. If you already have a smart meter it may need to be reconfigured which will still attract a cost of proximately $270.
