Quality Solar Hot Water Systems

Heating water with a traditional hot water system in your home accounts for around up to 40% of your total household energy use, and therefore, a large chunk of your energy bill each quarter.

On top of that, water heating is the largest single source of greenhouse gas emissions from most Australian homes, accounting for around 23 percent of the average household's emissions.

A solar hot water system can save up to $700 a year off your electricity bill as well as reducing your yearly household carbon emissions by a quarter – good for the environment and your family budget.

There are so many ways you can save with a Modern solar hot water system, and there is no better time than now to upgrade from an electric water heater to a solar hot water system.

Additional Solar Hot Water Information

How it works?

When the sun is shining, solar collectors from your Modern Solar Hot water system heat up the water in your solar hot water tank. This hot water is then circulated to the bottom of the tank. Hot water rises, so the heated water travels to the top of the tank and, whilst the sun is shining, more and more hot water is added and the water in the tank gradually heats up.


When you use hot water in your home, the water is provided at mains pressure from your Modern storage water tank. The hot water is drawn out near the top of the tank (this is the hottest part of the tank) and delivered into your home.

The solar collectors on the roof of your house are in the sun all day, it is common for the non-circulating water inside to get very hot. A tempering valve is supplied with all Modern solar hot water systems, which can moderate the temperature of water for safety reasons.

Electric boost solutions:

  • If you have continuous day rate electricity then Modern have a special solar thermostat built into the tank, which automatically senses when the water temperature has dropped from its preset temperature of 60°C. This automatically turns on the electric booster located in the centre of the tank, which heats the top half of the tank back up to 60°C.
  • If you have off peak rate electricity selected then the automatic thermostat won't turn on until the off peak electricity turns on in the middle of the night which shall provide power and once again heat the top half of the tank to 60°C.

System Components

Modern offer a range of solar hot water systems that allow you to generate your own hot water, reducing your carbon footprint as well as your energy bill. Each component of Modern's solar hot water system works in unison to provide your home with a sustainable, energy-efficient and cost-effective supply of hot water.

Modern Solar Collectors

Modern use only high efficiency flat plates with TINOX technology. Our patented solution includes a 95% titanium absorber, which still works when the sun is hiding behind clouds.

Each collector has:

  • 8 copper tubes and 2 copper heads to maximise heat transfer
  • 4mm high impact, low iron, tempered glass for maximum solar performance
  • Thick insulation wool to insulate the collector and reduce heat loss
  • An outer casing and back that is made of corrosion resistant aluminium

All Modern solar hot water tanks are lined with vitreous enamel and use an interior coat of silica glass, backed up by two magnesium sacrificial anodes to prevent corrosion. An electric booster is located half way up the tank to heat only the water you are about to use when there is not enough sunlight.

The Modern solar hot water control system circulates the water between the collector and the tank using an efficient pump. To ensure the water in the tank remains hot, the pump automatically turns on to pump water into the tank when the collector is hot, and automatically turns off as the collector cools down.


Rebates & Credits

Solar hot water rebates made available by the Federal and State governments have now closed, however, you may be able to take advantage of STCs to offset the initial cost of their investment in sustainable water heating solutions.

Renewable Energy Certificates (RECs) are part of Australia's Solar Credits Scheme. Recently renamed to small-scale technology certificates or STCs, RECs are an electronic currency earned when any renewable energy system such as solar panels or solar hot water systems are installed. This electronic currency can result in a huge discount on solar energy systems at point of sale; alternatively, they can be traded for cash. The value of RECs depends on the area in which you live and fluctuates according to market forces.

A single REC is equivalent to one megawatt hour of electricity generation. RECs can be seen as a measure of the efficiency of a solar hot water system and its ability to generate free hot water using the sun's heat. Essentially, more efficient systems earn more RECs. While RECs are offered for both grid connected systems and off grid systems, more RECs are generally earned for grid connected systems.

With climate change at the forefront of Australian politics and rising energy bills across the country, it is no surprise that more and more Australians are taking advantage of RECs – or STCs – and installing solar power in their homes and businesses.

All Modern solar products qualify for RECs, which can reduce the cost of a Modern system by thousands of dollars, depending on the area you live and the model purchased.

Types of Solar Hot Water Systems

Split System Solar Hot Water

A split system is made up of five key elements: the solar collectors mounted on the roof, a water storage tank, a solar controller, a small electric pump and an electric or gas booster.

Water from the storage tank is circulated by the pump to the solar collectors, where it is heated by the sun's energy. The heated water is then returned to the storage tank for use in the home when required.

The solar controller determines when the pump should run to avoid energy wastage and overheating water in the storage tank. If there is not enough sun, the electric or gas booster is used to heat the water.

Because the storage tank is installed discreetly on the ground, split systems have minimal impact on the appearance of a property, particularly when the solar collectors are mounted flush with the roof.

Modern offers a range of top-quality split system solar hot water models to cater for small or large households.

Roof-Mounted Solar Hot Water

A roof-mounted solar hot water system is made up of solar collectors and a water storage tank, both installed on the roof.

When the cold water receives heat from the sun, it rises into the water tank where it is stored until needed in the home. Any unused water that cools in temperature is returned to the collectors for re-heating.

A roof-mounted solar hot water system requires a roof that can bear the load of the water tank, which can weigh several hundred kilograms. If the roof is difficult to access, installation might be expensive.

Heat Pump Solar Hot Water

A heat pump hot water system is made up of a water storage tank and a heat pump mounted on top of or next to the tank. The heat pump consists of a condenser located around the outside of the water storage tank, a compressor and an evaporator.

Heat pump hot water systems work by capturing heat from the surrounding air, like an air conditioner in reverse cycle. Unlike solar hot water systems, heat pumps emit a noise when operating and generally cost more to run.

Heat pumps are generally installed when a home's design or location makes it difficult to install solar panels, or for homes in areas where there is a lot of frost.
