Through our database, Solar Choice has live quote pricing data for 1MW systems across all states of Australia. As an indicative guide, 1MW solar power systems can start as cheap as $1,100,000 for a straightforward installation with cost-effective products. There are some common factors that can influence the price of an installation:
The solar panels convert the energy from sunlight into direct current (DC) electricity, then inverters convert the power into alternating current (AC) that can be integrated into the electricity grid. LSS generation has grown rapidly in Australia and continues to hold an increasing share of Australia's total energy mix.
Cheap systems often cost more long term due to breakdowns, inefficiency, or required replacements. In 2025, Australians have more control than ever over how they power their homes. With generous government rebates and falling technology costs, both solar and battery storage are no longer out of reach.
Our support has helped to close the cost gap that existed between large-scale solar PV and other commercially competitive forms of power generation. As a result, utility-scale solar is now cost competitive with wind energy.
