Solar Power Shines in Adelaide: Comparing Prices & Installers

Adelaide, SA boasts an impressive 30-40% of homes equipped with solar panels, making it a prime destination for solar power. As electricity rates soar, more residents are embracing solar to harness the sun's energy. 

This article dives into the essentials of going solar in Adelaide, covering energy production, incentives, and the financial return, while also touching on home battery storage.

Illuminating Energy Production: Power from Solar Panels

Understanding a solar PV system's potential is vital when seeking the best solar deal. Solar panels generate electricity only during sunny hours, depending on the sunshine intensity and duration. 

The article presents energy generation estimates for common residential solar system sizes, highlighting their seasonal variations.

Calculating Solar Needs: Consumption and System Sizing

Determining the solar system size depends on factors like available roof space, budget, and SA Power Networks' restrictions. Solar panels' affordability allows for flexibility, with 5kW being the popular choice due to its value for money. 

Incentives and Rebates in Adelaide

The City of Adelaide's Sustainability Incentive Scheme provides rebates for solar PV and battery storage systems in specific postcodes. South Australia's appealing battery incentive scheme adds up to $3,000 for eligible solar batteries in Adelaide customers.

Furthermore, it is important to mention that Australian households are eligible to receive a single payment known as the Solarmarkit Electricity Rebate. This payment is designed to assist with cost-of-living expenses and to incentivize them to compare energy packages, ultimately leading to potential savings.

Feed-in Tariffs: Maximizing Solar Savings

Maximizing solar savings involves consuming generated solar power, and reducing reliance on grid electricity. The feed-in tariff, paid for excess solar energy sent back to the grid, varies based on electricity retailers and plans. 

Adelaide's solar households capitalize on this by reducing grid purchases, equating solar power's value to grid electricity.
