Mount Gambier is the second most populous city in what is arguably Australia’s most ambitious state for renewable energy uptake. A number of factors make SA a great place to install a solar PV system. However, the best returns on investment and shortest payback periods on systems are available only to Mount Gambier residents who find the best deals on their solar PV system. With the price of systems hitting all-time lows, plus Federal Solar Credits providing significant up-front discounts on the cost of an installation, systems have never been more affordable. South Australia residents also have access to the state’s Transitional Solar Feed-in tariff of 23c/kWh, which provides an excellent means of guarding against rising electricity rates in SA.
The advantages of installing a solar power PV system in Mount Gambier, SA
Find the best solar deals in Mount Gambier to harness the power of the sun
Finding the best deal on solar PV in Mount Gambier, or anywhere in Australia, depends first on understanding what a solar PV system potentially offers a home or business. Solar panels produce electricity only when the sun is shining, and how much electricity is generated depends on the intensity and duration of the sunshine.
The average Mount Gambier rooftop receives 3.7 hours of peak sun per day, averaged across the year. This number will be higher in summer and lower in winter, and the output of a solar system will fluctuate accordingly. With a 1.5kW solar array, 3.7 hours of peak sun will generate approximately 5.5kWh of electricity. A 2kW system in Mount Gambier will generate approximately 7.4kWh of electricity, a 3kW system in Mount Gambier will produce around 11.1kWh per day, a 4kW system 14.8kWh, and a 5kW system will generate around 18.5kWh per day.
Solar panel electricity production vs energy use in Mount Gambier
What capacity of solar power system to select for a home or business depends on a number of factors, including budget and aims. Electricity use patterns differ from house to house and from business to business, but to give a general example, an average 3-person home will use around 20kWh of electricity per day. A 5kW system, therefore, will produce roughly enough electricity to cover the needs of a 3-person household. However, a system of this size may be outside the budget range of certain households or businesses, who may instead opt to install a system with the intention of reducing their electricity bill.
Federal Government Solar Rebates for Mount Gambier
Under the Federal Government’s Solar Credit Scheme, solar systems (‘small-scale generation units’) are allotted a number of Renwable Energy Certificates (RECs, also known as Small-scale Technology Certificates or STCs). This number will be higher or lower depending on the location and the size of the system installed. It is important to keep in mind that STC prices change according to supply and demand. Solar installers will usually inform customers as to what price they give per STC when initial pricing details are settled on. (STC prices are also clearly detailed in Solar Choice’s Solar Quote Comparison sheets.)
Mount Gambier is located in REC Zone 4. (REC Zone and applicable STCs can be calculated for free on ORER‘s website.). A 5kW solar system installed in in Mount Gambier city would, for example, generate a base number of 103 RECs/STCs. When the Solar Credit REC Multiplier (currently 3x until 1 July 2012) is applied, however, the total number of STCs generated is (88 + 54 =) 142. This means that, assuming an STC price of $30, a discount of $4,260 off the up-front price of the system will be applicable. This up-front rebate is one of the reasons that solar PV system prices are currently reaching record levels of affordability across Australia and the world.
Electricity bill savings through solar PV systems in Mount Gambier: Transitional Feed-in Tariff and Self-consumption
Solar PV system owners in South Australia stand to benefit in two separate ways: 1) from exporting solar power to the grid under the state’s Transitional Solar Feed-in Tariff scheme, or 2) from consuming the solar electricity from their system as it is generated, thereby mitigating the need to purchase electricity from the grid in the first place. Fortunately, with a Feed-in Tariff of 23c/kWh (higher than the retail rate of electricity), Mount Gambier residents don’t need to be home and consuming their solar electricity to benefit from having a solar system–for the time being, exporting to the grid is more economical than using the solar electricity directly.
It is important to keep in mind, however, that the SA Transitional Solar Feed-in Tariff is composed of 2 separate components–a steady rate of 16c/kWh plus a ‘retailer contribution‘ of 7.1c/kWh for the remainder of 2012. The latter component is expected to continue rising (at a rate of several cents per year) as time goes on to match the ‘real value’ of solar power to the electricity grid, while the former is scheduled to expire on 30 September 2016. This means that after 30 September 2016, unless the retailer’s contribution has jumped to a rate equal to or nearly equal to the cost of retail electricity, it will make more sense for solar system owners to consume as much of their electricity as possible at home; to favour self-consumption over export to the grid.
Finding the best solar PV system deals in Mount Gambier
Good return on investment and short payback periods on solar PV systems are predicated on finding the best deal possible on a solar PV system. Most solar PV customers, knowing that cutting corners by looking only for the cheapest system possible can result in future disappointment, look for high-quality components at reasonable prices. Solar Choice, as Australia’s free Solar Energy Brokering and advice service, is uniquely positioned to identify the best deals on offer anywhere in Australia. Solar Choice can then match customers up with installers to help them find the solar system that best suits their needs and budget.
