Over the last few days I have highlighted some of the uses of solar energy in South Australia. I will conclude by mentioning my solar devices.
A few years ago I replaced my in-roof hot water service with this on-roof solar hot water service. As with the solar panels for generating electricity for use in the house, the solar hot water systems like this attract government subsidies. Without these subsidies the costs would be prohibitive and so far the savings made have been minimal - but the environmental savings justify the installation.
This is my yacht and the solar panel mounted on the back keeps the batteries topped up; sufficient to keep a fridge running and to run lights and electronic devices on board and still be able to start the motor!
