Solar hot water systems

Solar hot water systems take advantage of Australia’s supply of sunshine and use solar energy to heat water for household use. A solar hot water system should provide between 50 and 90% of your hot water needs—the amount depends on your local climate and the model of solar hot water heater you install. Solar hot water systems generally come with electric or gas boosters to provide the rest of your hot water needs.

There are many types of solar hot water systems (or solar water heaters) available so it’s important to do your research and choose one that suits your needs. You can consult the Solar water heater guide for households for comprehensive information to assist you before and after installation.

How do solar hot water systems work?

 

Solar hot water systems use solar collectors (either flat panels or evacuated tubes) which absorb energy from the sun to heat water for your home.

The heated water is then stored in an insulated tank for when you need it. The solar collectors are usually located on the roof of your home—they are best positioned facing north.

On cloudy days, or when hot water usage is higher than usual, your hot water system may need a boost. The booster will come on when the temperature of water in the storage tank falls below the thermostat setting and turn off automatically when the water reaches the required temperature.

For more control over the system, a manual booster switch and a timer may be installed to ensure you make the most of the amount of energy coming from the sun to heat the water. A gas booster generally produces less greenhouse gas emissions than an electric booster.

If you live in a frost-prone area ask your retailer about frost protection for your solar hot water system.

To maximise the benefits of installing a solar water heater ensure you understand how solar water heaters work, the best type for your particular circumstances as well as how they should be installed, operated and maintained.

The benefits of solar hot water systems

Solar hot water systems generally cost more to buy and install than other types of water heaters, but the extra upfront cost will be recovered over the life of the system through reduced energy bills.

Solar hot water systems will recover their costs more quickly in larger households, in warmer parts of the country, or where there is plenty of access to sunlight.

The benefits of solar hot water should outweigh the upfront cost:

The difference in cost will be paid back as you’ll spend less on heating water.
You’ll reduce the amount of greenhouse gases your home produces.
And of course another major benefit of solar hot water systems is that they use a renewable energy resource.

If you decide a solar hot water heater is the best system for your household ensure you understand how different electricity tariffs will impact your bills and install the system correctly.

7 reasons to choose a solar hot water system

Solar Hot Water Heaters

By installing a solar hot water heating system in your home you can:

  • ENJOY free energy from the sun
  • PROTECT yourself from rising energy costs
  • SAVE up to 90% on your water heating bills*
  • Access RELIABLE hot water 24/7
  • DECREASE your household’s carbon footprint
  • INCREASE the value of your property

Solar water heaters use the solar energy from the sun to generate heat – not electricity – which can then be used to heat water for your household. Depending on the climate you live in, Solar Hot Water heating systems can provide up to 90% of your hot water for free using the sun’s energy – without generating greenhouse gas emissions.*

Water heating is the largest source of greenhouse gas emissions from an average Australian home. It accounts for nearly 21% of the energy and generates about 23% of the greenhouse gas emissions.* Electric water heaters, in particular, contribute to these emissions. Only 50% of Australian homes use electric water heaters and they contribute 80% of hot water greenhouse emissions.

In Australia, the split of energy used for water heating comes from**:

Natural gas 48%
Electricity 45%
Liquefied Petroleum Gas (LPG) 3%

An efficient hot water service can also add value to your home and help meet state, territory or local government regulations.

The solar revolution on India’s rooftops is gaining momentum.

The country added more rooftop solar power capacity in the last financial year than in the previous four years combined, making it the fastest-growing segment in the country’s clean energy space. During the financial year 2017, some 715 megawatts (MW) of systems were added, up from 227 MW in the previous year, taking the country’s total installed capacity to 1.3 gigawatts (GW, 1 GW = 1,000 MW) according to a report (pdf) by Bloomberg New Energy Finance (BNEF). By 2022, the report estimates that the country will have around 9.5 GW of rooftop solar capacity—but that is still substantially short of the Narendra Modi government’s target of 40 GW.

This has happened largely because rooftop solar power is now cheaper than commercial and industrial power in all major Indian states, according to BNEF. Besides, costs have halved over the last five years. Overall, because of increased competition and low solar panel prices, setting up rooftop systems has become cheaper than the global average by between 39% and 50% in India.

“If a mall is purchasing power from (a) grid at Rs8-9 (per unit)…going by (the) rooftop model, the power cost will be half of that. So it is a viable proposition,” Gautam Bafna, an analyst at CARE Ratings who tracks the renewables sector, told Quartz.

Government incentives and policies to push rooftop solar installations have also contributed to the growth over the last year, Bafna added. For instance, the government has held auctions to have companies set up over 1 GW of rooftop projects in the first nine months of 2017.

Meanwhile, the size of installations is getting bigger as well. The average size of a rooftop system has increased from 250 kilowatts (kW) in 2015 to 855 kW in 2018, according to BNEF. This is due to better utilisation of rooftop space and consumers’ willingness to use power generated from their own buildings rather than purchase the power from elsewhere, the report said.

90 percent energy self-sufficiency almost reached

Solar energy efficiency.
With a combination of a 34 kW photovoltaic installation, energy storage, and a small wind turbine energy pioneer Andreas Haehnel reaches over 80% energy self-sufficiency. An electric heating system electric car charging is integrated.

“Not for me!”, said Andreas Haehnel. In a land where the conventional electric power system looms over the energy landscape as the mighty Roman Empire once did over its vast domains, Mr. Haehnel’s house in the Bavarian town of Burgthann stands out like a small, rebellious Gallic town, evoking the image of the heroic Asterix from the well-known European comic strip of the same name. In this same spirit, Mr. Haehnel has taken it upon himself to be a pioneer in the movement toward renewable energy. And for this undertaking he is relying on Fenecon Technologies.

The Challenge
Independence is a noble goal for many people. However, when it comes to self-sufficiency in the area of power generation, it is not that easy. “It simply was and still is not”, explains Mr. Haehnel. “I have invested a lot of time and money together with my project partner in order to get to where I am today: nearly 90% self-generated power. Integrated yet decentralized power generation is, in my opinion, the best strategy for bringing about my own personal energy transformation.” As an employee at a regional brewery, Haehnel is no expert in the area of power generation. He is, nevertheless, what you might call a man of conviction. He places great value on maintaining a high quality of life.

And technological solutions are indispensable toward this end. Not only does this project require will and knowledge, but the wide range of potential solutions and combinations of technologies presents a challenge to those interested, because there exists such a large variety of providers when it comes to power sources; the conversion into household electricity as well as its storage or management; and the necessary consultation for such a project. It was clear to Haehnel from the very beginning that the project would require a great deal of personal initiative and that he would have to rely on trustworthy partners in order to profit from their experience and knowledge.

Own personal energy transformation

As for his own knowledge, Haehnel applied the learning-by-doing method, along with skills learned in a partial apprenticeship as an electrician. His enthusiasm for electricity and renewable energy can also be seen in his appearances as a tester of electric cars on YouTube. Even his house, which he built in 2000, was configured to facilitate his own personal energy transformation. The “energy rebel” laid out the following basic functions required for his home: transportation using electric cars, 90% self-sufficiency for electricity consumption and heating from an intelligently operated renewable energy supply management system, which he hopes to use as a model for other buildings.

Two storage systems
In order to reach this ambitious goal using solutions from the variety available on the market, Haehnel chose Fenecon. “Our team is very young and engaged, and we were

all very impressed by how much energy Andreas Haehnel brought to the project.”, declared Franz-Josef Feilmeier, CEO of Fenecon. The dimensions that Mr. Haehnel specified for the solutions are considerable: The sun is to be the main source of energy tapped by a photovoltaic unit with a peak output of 34 kilowatts, the modules of which will face south, west, and even north. Additionally, a small wind turbine will contribute 800 watts of electricity.
