What technology will be used for the project?webkNeoen’s Western Downs Green Power Hub will work very similarly to residential solar photovoltaic installations. The project’s solar panels will use solar irradiance to generate direct current, which will then be converted into alternative current with solar inverters, and be stepped up to 275kV to feed Western Downs and the national electricity grid. New technology breakthroughs happen on a regular basis; as such, the mounting system will be selected in the final stages of development. Neoen is experienced in financing, constructing and operating several different types of systems including north-facing fixed tilt systems, east/west-facing fixed tilt systems and single-axis tracking systems. Photos of Neoen solar plants with these technologies can be found in the library section of this website.
When will the project be constructed and how long will it take to build it?webkNeoen anticipates that construction will begin August 2018. Construction timeframes can vary depending on the number of workers deployed on site, but a 12-18 month timeframe is anticipated.
What will be the life cycle of the solar farm?webkSolar panels generally come with a 25-year manufacturer warranty. Depending on the local environment they can generate power for 30 years or more, with only about half a percent of efficiency loss each year. Neoen intends to operate the Western Downs Green Power Hub for 25 to 30 years, and may consider replacing the whole equipment with newer technologies once the initial project has been decommissioned
Is it true that it requires more energy to manufacture a solar panels than it will ever generate?webkSeveral independent studies have concluded that depending on the technology and the project location, the energy payback of a solar panel is somewhere between 1 and 3.5 years, with newer technologies reaching the best results. This means that on average solar panels will produce more than ten times as much energy as is required for their fabrication and installation.
Will the solar panels generate glare?webkSolar photovoltaic panels are designed to reflect as little light as technically possible (generally around 2% of the light received) in order to maximize their efficiency. Therefore solar photovoltaic farms are not considered reflective and have even been installed on a number of airports around the world.
