Moving On From A Solar Hot Water System To Solar Electric Panels

by John


On November 1, 2002, we installed a solar hot water system which preheated our hot water for household use and in winter, assisted with heating the house through a ducted hydronic gas heater system. In addition, we used a gas heater to supplement the solar hot water heating as required.

Recently, there has been a sharp increase in the cost of electricity in Australia which is primarily supplied by coal fired electricity generators. For instance, these generators supply the city of Melbourne and the State of Victoria. Also, there has been some wind turbines and gas fired generators contributing to the grid.

As a result, we have decided to use solar panels which contribute to the electricity grid and thus help cut our power bills.

The payback period quoted in the documentation is 15 years. However, other friends who have completed the switch have found that the payback period has proved to be only about 4 years. This has been due to the increase in the price of electricity.

Overall, I believe that this is a great way to reduce our greenhouse gas emissions and help stop climate change.

Knowing When To Install Solar Panels
by: John Cosstick

Thanks for these comments on this issue. We made a mistake in not doing the switch to solar electric panels earlier when the tariff for feeding into the grid was higher. However, there will never be a perfect time to make the switch.

Yes, Bob Brown did a good job during his years leading the Greens in Australia. Most fair minded Australians of any political party will say that.

Thanks for commenting on my post.

Value Of Your Home Goes Up
by: Liz

The value of your home would also be higher because of any type of solar option, that makes the cost of living in that home lower. Well done for making an excellent choice, (I wish I had when it cost very little) and good that it will be paid off sooner than you thought.

There are so many things that each of us can do. Bob Brown who used to be the leader of the Australian Greens (political party in Australia) and an activist for climate change was talking yesterday, and he was saying that he is setting up a new foundation.

Its aims are to fund environmental projects. It will be interesting if they come up with other ways the average person can help the environment and themselves at the same time. A win-win situation!

Solar Power Cost
by: Shirley

John, I agree solar power is great. One of the biggest stumbling blocks is cost. To hear the investment pays off sooner rather than later makes a difference. Thanks!
