There has never been a more affordable time to install a solar electricity system on your home. The Solar Credits Scheme provides significant discounts at the time of purchase, whilst the Premium Feed-in-Tariffs can help you pay off the system quickly and even earn money over many years. A solar electricity system has a typical lifespan greater than 30 years and represents an excellent investment to save on your future electricity bills and improve the value of your home.
There are a number of reasons warranting the installation of a Solar Electricity System:
All you need is a pitched roof with a predominantly northerly aspect, an inclination between 20° and 30°, a useable rectangular area of at least 12m2 that is ideally free of any obstructions and is free of shade throughout the day. If you are unsure, please ask our friendly staff to help you assess the suitability of your roof. Generally, this can be determined from a simple telephone interview and using Internet tools such as Google Earth to view your roof. Depending on the complexity of house’s design, a site inspection maybe necessary and this will be organized to suit your availability.
The panels are rectangular; which must be kept in mind when estimating the usable area of your roof. It is not permissible to have panels overhanging the roof. For tiled roofs, the edges of the array must be at least 150-200mm from the closest ridge tile. As a guide a 6 panel or 1kW array has the nominal dimensions of 5.1m x 1.6m.
Typical roof area required by system size:

Gold Coast Energy offers a large range of solar electricity system sizes and configurations designed to suit almost any need and budget.
The size of the system chosen depends on a range of key factors including;
The Solar Credits Scheme in its current form provides the greatest percentage discount for a 1.5kWp solar electricity system but this size system may not meet your total electricity demand. The level of discount reduces as the system size increases. But because larger systems generate more electricity, they may not only meet your average daily demand but significantly exceed it. This is especially important for net premium feed-in tariff schemes where only excess electricity generation is eligible for payment at the higher tariff. The more electricity that can be exported to the grid, the greater the earnings and financial return. In some cases these systems could finance themselves.
The Government’s RET scheme is designed to ensure that 20 per cent of Australia’s electricity comes from renewable sources by 2020. The new RET laws include the Solar Credits mechanism to boost support to Australian households and businesses installing small scale solar systems.
The Solar Credits mechanism works by allowing eligible households, businesses and community groups at the time of installation to create STCs equivalent to the output of up to 15 years operation; and for the first 1.5kW of capacity installed, multiply their number. The scheme is designed to allow the system owner to transfer the right of STC creation to their system provider in return for a discount on the system price. This provides an upfront capital subsidy to the householder. The householder if they choose may create the STCs themselves.
Solar Credits are available for eligible systems installed on or after 9 June 2009. Solar credits apply to the first 1.5 kilowatts (kW) of capacity installed. Generation from capacity above 1.5 kW is only eligible for the standard 1:1 rate of STCs creation.
STCs are a tradeable form of currency equivalent to 1 Megawatt hour of electrical energy produced. Many renewable energy devices or installations, including residential solar photovoltaic systems that reduce carbon emissions have a STC value attached to them. STCs can be traded for money or “surrendered” / “retired” (removed from trading circulation) to ensure additional renewable energy capacity is added.
The STCs are a tradable commodity and; thus, are subject to price volatility. As the STC price increases, so does the level of the Solar Credits discount.
Gold Coast Energy, on its quotation, will specify the STC price it is currently offering and the level of Solar Credits discount available at this price. If you choose to sell your REC’s to Gold Coast Energy, the balance payable for the solar electricity system will be determined as well.
To be eligible, the following conditions must be met;
This is our step by step process:
A standard installation comprises;
Peace of mind that Gold Coast Energy is a local company which has been on the Gold Coast since 2008. We are at the forefront of ecologically sustainable engineering and design excellence.
Gold Coast Energy has installed over 6,000 systems in the Gold Coast, Northern Rivers, Brisbane and surrounding areas, and are passionate about the future of green energy. We practice what we preach. Due to the PV installations on our commercial premises, we are a 100% carbon neutral business!
Gold Coast Energy offers a market leading 10 year limited written Product Warranty and a minimum Performance Guarantee of 25 years. The performance guarantee is 90% of initial output after 10 years, and 80% after 25 years. The expected lifetime of photovoltaic panels is in the range of 30 – 40 years.
Gold Coast Energy offers a range of high quality and high performance inverters to suit a range of budgets and performance requirements.
All inverters supplied by Gold Coast Energy are weatherproof IP65 rated. They can hang on any external wall that is preferably sheltered from rain and direct sunlight. Extreme temperatures affect the internal operating components and may shorten their operating life. The inverters may be installed internally provided there is adequate air ventilation..
Yes, it is possible to upgrade/expand your solar system at any stage by adding more PV panels and a larger capacity inverter. Should you do this from the outset? Generally, yes. Future expansions will incur an additional installation charge.
Gold Coast Energy can provide assistance in determining whether an upgrade or expansion is possible. We also recommend that before proceeding, you should inquire with the previous supplier/installer whether contracting another system provider for the upgrade would void the warranty on the existing installation.
Take Victoria as an example where the State is split into Zone 3 and 4, the solar irradiance is low in winter but extremely high in summer (exceeds Sydney and Brisbane). This coincides with extremely high electrical cooling demand.
The Victorian average household uses about 16-18 kWh (kilowatt-hours) per day. A 1.5kWp system will produce approximately 6 kWh of electrical energy per day on average. This could be as high as 10-12kWh per day in summer and as low as 2 kWh per day in winter.
Assuming that 4kWhr/day are fed into the grid and 2kWhr/day are used in the household from the Solar Electricity system, the saving calculated is as follows;
|4 kWh @ 66cents/kWh (Origin Energy)||= $2.64|
|2 kWh @ 20cents/kWh||= $0.40|
Equivalent kWh based on saving is $3.00/$0.20 = 16.6 kWh. This is in excess of average daily usage of 16 kWh.
Based on this analysis, with approximate annual savings of $800-$900 from a 1.5kWp solar electricity system, a Zone 4 customer with a final balance payable of $3,500 will yield an approximate 25% return on investment. The system will be paying for itself in approximately 4 years. If the balance payable for customers in Zone 3 is $2,500, then the return on investment is approximately 35%. The system will pay for itself in 3 years.
Property evaluations are used to understand the specific circumstances of each resident’s house, switchboard and meter-box. This will also help us determine whether there will be a variation to our advertised pricing as well as whether electrical upgrade work is required prior to installation.
