An enormous 500-kilowatt (kW) solar photovoltaic (PV) system has just been installed by Autonomous Energy in Melbourne. Two thousand Kyocera solar panels now cover the roof of Toyota Australia’s Engine Factory at its Altona North plant.You think an industrial factory is going to run on solar panels? It's commercial reality - if the production cost is higher due to higher energy prices, they wouldn't sell one panel. Industry doesn't get solar rebates from power companies, you know.
