Solar System lie within a nearly flat disc called the ecliptic. The Solar System also contains smaller objects. The asteroid belt, which lies between the orbits of Mars and Jupiter, mostly contains objects composed, like the terrestrial planets, of rock and metal. Beyond Neptune's orbit lie the Kuiper belt and scattered disc, which are populations of trans-Neptunian objects composed mostly of ices, and beyond them a newly discovered population of sednoids. Within these populations are several dozen to possibly tens of thousands of objects large enough that they have been rounded by their own gravity. Such objects are categorized as dwarf planets.
Solar power in Australia the state government announced a new round of finance for renewable energy projects which included a Planet Arc Power - Schneider Electric development of a $13.9m solar PV and battery project at a major distribution centre in Adelaide’s North. The project includes a micro-grid management system optimising 5.7MW of solar PV coupled with 2.9MWh of battery storage. The University of South Australia will develop 1.8MW of ground and roof mounted solar PV at its Mawson Lakes campus. At the Heathgate Resources Beverley mine there are plans for a relocatable 1MW of solar PV paired with a 1MW/0.5MWh battery which will
