Summary of the Solar Report March 2023

State of Solar in Australia

• Total rooftop solar capacity has increased to 21.2 GW by the end of the third quarter, with 68,500 new installations contributing 620 MW. New South Wales leads with 34.8% of national installations.
• Average system size stabilized at 9.3 kW, influenced by technological advancements, consumer optimization, and reduced feed-in tariffs.
• Battery storage adoption grew, with Victoria and New South Wales leading new combined solar-battery installations.
• Government incentives vary by state, with a national net-zero target by 2050.

Electric Vehicles

• Electric vehicle sales surged by 269% year-over-year, with 46,624 EVs sold in Australia; battery electric vehicles (BEVs) dominate the market at 83%.
• EV adoption is linked to solar ownership, increasing the probability of BEV ownership by 34%. Economic and environmental benefits include cost savings and carbon reduction.
• Government support includes rebates and infrastructure development, but current policies face criticism for not addressing freight transport emissions.

Levelized Cost of Energy (LCOE)

• Solar energy cost varies by location and discount rate, ranging from $0.06 to $0.42 per kWh. Grid parity is reached when LCOE matches retail prices.
• Sensitivity analysis shows higher discount rates increase LCOE, while business systems (10 kW and above) offer lower costs, supporting commercial solar adoption.

Payback Period

• Payback period depends on system size, initial investment, and discount rates. Smaller system sizes like 5 kW show faster payback in cities such as Melbourne.
• Factors include electricity price increases due to inflation and feed-in tariff declines, with some regions maintaining short payback periods despite high interest rates.

Methodology

• Data sources include Clean Energy Regulator figures with a 12-month reporting lag. Payback period calculations consider investment, savings from electricity avoidance and feed-in tariffs, but excludes maintenance costs.
• LCOE is based on retail prices and historical mortgage rates, with sensitivity tested across different discount rates, including business-specific examples.
