Solar energy is a highly viable alternative to the conventional electricity infrastructure in Australia due to its economical nature and the country's ample sunshine. Installation and the total solar system cost can vary from $3,800 to $15,000. However, solar fees are contingent on various factors, including the quantity of panels, the system's quality, and the anticipated output.

Solar electricity is environmentally benign but a long-term investment lasting for years. Solar energy costs vary greatly depending on where you reside, the merchant or installation you choose, the size of your system, and additional components. As an alternative, you can choose a portable solar system - Jackery Solar Generator - with a lower cost and bigger capacity to power most of your home appliances. 

To understand the current solar cost in Australia, you must first know that the advertised solar power system price usually includes the installation cost. However, you may be eligible for additional benefits after qualifying for solar panel subsidies.

The price of solar energy will vary substantially depending on your location, the scale of the solar system you implement, and the quality of the materials used in the installation. Generally, solar expenses are subdivided into solar panels, inverters, and installation costs. Installing a solar battery into a solar system will incur an additional fee.

The average cost of solar systems in Australia was $5,667, as reported by Canstar Blue. 

Government subsidies have contributed to the reduction in solar panel costs in Australia. As a result, solar energy systems are more economically viable in this region than most of the world.

Per Watt: The initial step in ascertaining the cost per watt of the solar panels is to evaluate the system's overall dimensions and the applicable state-specific rebates. As an illustration, the cost per watt of a 6kWh panel system is approximately AUD 1.04. Nonetheless, when the system capacity is increased to 12 kWh, the price falls to AUD 0.92.

Per kWh: When the global solar power industry is considered, the cost of panels per kilowatt-hour in Australia is among the most affordable. As a result of government rebates, initiatives, and the nation's burgeoning solar industry, prices have become extraordinarily affordable for the average citizen. For instance, the cost per kilowatt-hour (kWh) for a high-quality solar panel system can range from $800 to $1000.

To offset the cost of solar panels and installation against their electricity expenses, the typical householder requires 28 to 34 solar panels. Assuming households' average annual electricity consumption is around 10,000 kWh, these figures are derived from the power output of 250-watt panels.

A kilowatt-hour is consumed when one thousand watts of power are used for one hour. Thus, if your residence contains twenty 50-watt light bulbs, leaving them on for an hour consumes one kilowatt-hour of electricity. The cost of solar energy in Australia has decreased significantly over the past decade, with larger systems costing the most.

• The typical cost for a 3 kW solar system and installation is $5,250.
• The government rebate is $1,005.
• The overall price for a 3 kW solar power system is approximately $4,245.

A 6kW solar photovoltaic system would cost between $4,000 and $6,000 in most Australian states, while a 10kW system would cost between $7,500 and $10,500. The starting price for a 5kW solar system of satisfactory quality in Sydney is $5,500 on average. Approximately $7,000 should be budgeted for panel-level output.

Including every conceivable feature, high-efficiency panels cost nine thousand dollars. The International Energy Agency (IEA) reports that the global installed photovoltaic (PV) capacity is at least 627 GW. Solar energy accounted for approximately 3% of global power generation in 2020.

As demonstrated previously, Queensland had the most extraordinary average solar costs. Victoria and South Australia residents followed suit, while New South Wales and Western Australia registered the lowest solar installation costs.

Solar panels are available in basic and premium varieties due to variations in energy output and lifespan among manufacturers. The cost of a 5kW monocrystalline solar panel is greater than that of any other variety.

Adding battery packs, power/utility meters, and inverters can substantially increase the price of installing solar panels on a residential property. Although including these supplementary elements raises the overall cost of solar systems, they can also yield advantageous outcomes.

Every solar panel requires an inverter. A 4 kWh premium inverter may cost approximately $2,000. A solar battery pack facilitates the storage of surplus energy generated by a solar panel during the day for later use, such as on overcast days or at night. A Tesla 13 kWh battery could cost approximately $12,000. Additionally, you could reduce expenses by taking advantage of solar battery incentives.

Power metres indicate the quantity of electrical energy consumed and returned to the grid. A standard monitoring system is included with most inverters to provide fundamental power generation and consumption data. Consider incorporating a smart meter to provide additional information, such as a notification when your system is operating at a suboptimal level.

Instead of wasting money on upfront solar costs, consider purchasing an all-in-one portable solar system, such as the Jackery Solar Generator, which integrates solar panels with a mobile power station to convert sunshine into electricity. The Jackery Portable Power Station includes a first-rate lithium battery, MPPT charge controller, and pure sine wave inverter.

Solar energy costs vary significantly depending on the choices you make on the solar panel, inverter battery brand and solar system size, the location of your home, type of roof and the local solar installation market. These are some of the most critical factors affecting the cost of picking and installing a solar system.

Solar System Size: Because solar panels are available in various capacities and configurations, a 10kW solar system will be more expensive than a 3kW system. An increase in the size of your solar system, expressed in kilowatt-hours (kW), will not only result in a greater output of electricity but will also necessitate a more suitable roof area to accommodate the necessary dimensions of the solar panels.

Solar Installation Costs: As with all significant financial outlays, shop for at least three quotations before committing to a purchase. The rates set by the installer are their own, and they can vary considerably from smaller or local retailers to chain retailers, depending on whether the installation is included in a package or not.

Factors such as the condition and accessibility of the roof, the size of the solar system, whether a more complex monitoring system is desired, local regulations governing solar installers, and the feasibility of repairing an ageing roof before solar panel installation are all significant considerations. 

As a result of the abundant sunlight in Australia, installing will significantly reduce your electricity bill. As an illustration, a 6kW solar system producing 10,000 kWh per year can result in savings ranging from $1,400 to $1,600. Anticipated savings over two decades are between $28,000 and $32,000.

However, the computation of the precise amount is complex due to numerous factors. Your electricity rate fluctuates frequently by your usage patterns. Determining the average unit of power consumed is thus the initial stage in estimating the amount of money that can be saved through solar energy. Divide by two the unit of electricity consumed during a given period.

Your solar energy savings will also grow with the rising electricity rate. Solar panels ultimately recoup their investment through reduced electricity expenses and, in certain instances, revenue generation via feed-in tariffs. Depending on location, solar panels in Australia have a repayment period of five to eight years. Investing in solar panels is highly advantageous, notwithstanding their maximum repayment period of 8.2 years.
