Case Study: How Solar Power and Solar Hot Water Delivered Big Energy Savings for a Large Tasmanian Home

Why Combine Solar Power and Solar Hot Water?
Australia has the most solar per capita in the world. It is a title Aussies can be proud of as we lead the charge towards a cleaner, more sustainable future.
In fact, as of late 2024, Australia reached the remarkable landmark of four million solar installations, up from just 22,000 in 2008.
However, did you know you can have both solar power and solar hot water to lower your energy consumption even further? Both solar technologies work together to deliver maximum savings for you and your family by reducing your reliance on fossil fuels in favour of one of the most abundant, consistent sources of energy we have available: our Australian sun.
Benefits of Solar Power
Solar power combines panels and an inverter to power your home. More Australians are switching to solar power to:
- Generate their own electricity.
- Reduce their reliance on the grid.
- Help future-proof their home against rising energy costs.
Benefits of Solar Hot Water
Solar hot water helps reduce the amount of energy required to heat water and stores it in a tank ready for your use. Hot water is one of the biggest energy drains on homes, accounting for approximately 25% of the average Australian household’s total energy use.1 By switching to a Solahart Solar Hot Water system, you could significantly save on your water heating energy consumption.2
Real Results: A Large Tasmanian Home Saves 60%
Kylee, a Solahart Tasmania customer, said solar was an important decision. Ten people reside in their multi-generational home, where bills can skyrocket if they rely solely on the grid for their energy needs.
“We chose to get solar primarily because it’s a large house; there are ten people living in our house, a multi-generational home,” Kylee said.
“That was always going to cost us, we knew that, so solar was always on the cards from a saving money, cost point of view."

Kylee and her family have solar power and solar hot water systems installed on their roof to produce more of their own energy. This has resulted in savings of about 60% on their energy bill.
“From an energy savings point of view, we’ve only been in the house for a short amount of time. But, from the comparisons that we’ve made from the earlier bills to now, it’s got to be about 60% on our bill,” Kylee said.
“And with a house this big with this many people, we were super stoked.”

Kylee praised her experience with Solahart: “Our relationship with Neil [Solahart representative] has been great right from the start. He looked over our plans [for the house], made his own plan for our build, which was great. We felt really confident in what he’s doing; he’s great at explaining things. It’s just reassuring to know that these guys are doing their job well,” Kylee said.
