A Comprehensive Guide to Solar Power Systems in Australia
Are you curious about how solar power works and what it means for your energy needs in Australia? In this post, we’ll take a closer look at the basics of solar power systems, how they operate and some of the benefits they offer to homeowners and businesses.
Solar Power System Basics
Solar power systems harness the energy of the sun and convert it into usable electricity through the use of solar panels or photovoltaic cells. These cells absorb sunlight and transform it into direct current (DC) electricity. An inverter then converts this DC electricity into alternating current (AC) electricity, which can power homes or businesses.
One key advantage of solar power is its versatility. Any excess electricity generated by your solar panels can be stored in batteries or sent back into the grid. This means you can make the most of the energy you produce, even on cloudy days or during nighttime hours.
On-Grid vs Off-Grid Systems
In Australia, most residential solar power systems are on-grid, meaning they remain connected to the electricity grid. This allows you to purchase electricity from the grid when your solar panels aren’t generating enough power whilst also allowing you to sell any surplus energy back to the grid. It’s a cost-effective way to balance your energy needs.
On the other hand, off-grid systems, which consist of solar panels and batteries, are an excellent choice for those seeking a standalone power source. While the initial cost of off-grid systems can be significant, they offer the advantage of free power for their entire lifespan. This makes them increasingly popular in rural areas where grid access is perhaps limited.
Saving Money with Solar Power
One of the primary benefits of solar power is its potential to reduce your reliance on grid power and save you money. Grid-connected solar systems prioritise solar energy, which can lead to substantial savings on your electricity bill. In Queensland, for example, electricity prices typically range from 28 to 40 cents per kWh as of July 1, 2023. By offsetting your energy consumption with solar power, you can expect to reduce your energy bills by anywhere from 30% to 70%.
Understanding Australia's Solar Rebate
Australia’s Small-scale Renewable Energy Scheme (SRES) was introduced in 2011 to promote the adoption of renewable energy. The scheme issues Small-scale Technology Certificates (STCs) to homes and businesses that install solar power systems with a DC capacity of under 100 kW and have them commissioned by a Clean Energy Council-accredited Solar Installer. The number of STCs you receive is based on factors such as your postcode, the solar panel capacity of your system, and the time left until 2030. Once your system is commissioned, your solar installer or broker/aggregator can sell your STCs on the market. The rebate value changes annually on January 1st, so if you install your system after the new year, there may be a slight difference in the rebate value. Generally, the rebate amounts to around 30-35% of the total system cost, making it a great incentive to switch to solar power.
How long will it take to get a return on investment (ROI) from a solar power system in Australia?
Unfortunately, there is no one-size-fits-all answer, but don’t worry. We are here to help. The time it takes to see an ROI depends on various factors, including the size of the system, your energy usage and the cost of electricity in your area. Typically, most households expect an ROI within 3 to 5 years.
