Cost & Estimating Costs
A Residential Solar PV System from Solar Galaxy costs from $3,000 to $6,500 for a 6KW to 13KW system. These prices include federal government Small-scale Technology Certificate (STC) incentives. On average, expect to pay between $3 to $5 per watt; for example, a 5-kilowatt (kW) system may cost between $15,000 and $25,000 before incentives. With government subsidies, you could save between $2,000 and $7,000, although these incentives decrease annually by 5% as part of a phase-out program, scheduled to reach zero by 2030.
What are the benefits of installing Solar Panels
The benefits of installing Solar Panels are:
- Reduce your electricity bill
- Reduce your carbon footprint
- Add value to your property
- Get paid for excess energy
- Low maintenance operation
- Reduce grid reliance
Solar power is an excellent way for both homes and businesses to generate renewable energy. By harnessing the sun’s heat and light, you can reduce your reliance on fossil fuels while enjoying numerous financial and environmental benefits
Reduce your electricity bill
Solar power can significantly lower your electricity bills. By generating your own energy, you can reduce or even eliminate traditional energy costs over time.
Reduce your carbon footprint
Solar installations help prevent harmful greenhouse gas emissions and reduce your overall carbon footprint, supporting a cleaner environment.
Add value to your property
A Solar PV System increases your property’s value.
According to a study by Origin Energy (2018), 77% of Australians believe homes with solar are more valuable than those without. Additionally, 57% of homeowners would pay up to $10,000 more for a home with solar, and 60% would pay even more if it includes a battery.
Get paid for your excess energy
Feed-in tariffs offer a financial return. Exporting excess solar power to the grid allows you to benefit from attractive buyback rates.
Low maintenance operation
Solar systems require minimal upkeep. Most systems last 25–30 years with little maintenance, though periodic checks ensure continued efficiency.
Reduce grid reliance
Generating your own electricity reduces dependence on the grid. This creates a safer and more self-sufficient energy environment for your property.
What factors influence solar panel installation costs
- System Size: Larger systems generate more electricity but require a higher initial investment.
- Location: Local labour rates, permitting requirements, and weather conditions all affect costs. Some regions offer additional rebates or incentives.
- Type of Panels: Monocrystalline panels, though more efficient, are generally more expensive than polycrystalline options.
- Roof Condition: The structural design and condition of your roof may require repairs or modifications before installation.
- Inverter Type: Choices between string inverters, microinverters, or power optimisers influence overall costs.
- Labour Costs: Vary based on installation complexity and local wage rates.
- Energy Consumption: Your household or business energy needs determine the optimal system size and type.
Considerations & Cost Analysis
While solar power offers long-term savings and increased property value, these benefits come with high initial costs that vary widely. Understanding your investment requires considering factors such as:
- Total system cost: The combined price of panels and installation.
- Energy production: How much electricity the system will generate.
- Alternative energy costs: Your current expenditure on equivalent energy.
- Payback period: The time it takes for your savings to cover the initial investment.
- Investment return: Whether the system can pay for itself within five years.
