People should be considering solar hot water (SHW) and solar power (PV) in combination, rather than entirely covering their roof with PV
Prior to 2010, the word ‘solar’ referred more to Solar Hot Water (SHW) than to PV. While solar power was a cottage industry, there were tens of thousands of SHW units being installed every year. At its peak in 2009, the Australian SHW sector installed 200,000 solar water heaters (including air-sourced heat pumps), compared to just over 50,000 PV systems. This all changed in 2010 as PV overtook SHW to be the dominant solar technology in Australia.
