A 50kW solar system in Australia costs $46,100 – $51,400, produces around 190 – 220 kWh per day, and typically suits commercial sites aiming to save $15,500 – $18,000 per year, depending on usage and feed-in tariffs. All prices in the tables below include incentives available through the federal Renewable Energy Target (i. STCs) as well as GST, but do not incorporate meter installation fees or additional costs such as ground-mounting, grid protection or grid connection studies. A 50kW solar system generates an average of 200kWh daily, but this output varies. Based on this data we can see the average cost of a 50kW system as of August 2024 is $50,480 including the STC rebate and GST. For higher quality components from top tier manufacturers with highly efficient inverters the prices will start from $55,000. 45 kwH daily and delivering savings of up to $16,432 per year, this solar energy solution is designed to achieve robust solar energy generation and usage results.
