Solar Power or Solar Hot Water? Or get smart and get both.

Solar is often associated with solar power (PV), where the sun, a natural energy source, is used to generate and provide electricity for your home.

However, solar hot water is actually more efficient and a fantastic way to reduce your energy consumption. More and more Australians are realising its benefits, as they take advantage of Australia’s abundant sunshine to heat water, rather than rely on the grid.

In this article, we will explore both solar technologies (solar power and solar hot water) and how they also work together to deliver great benefits for you and your family.

Why solar hot water?

If you’re looking to go solar, a solar hot water system is a great start as it will help reduce the amount of energy you use in heating water. This technology uses the free energy from the sun to heat water and given that conventional water heating accounts for around 25% of the average Australian household’s energy use1, installing solar hot water could result in significant energy savings for your home.

Solar hot water collector panels are more efficient than solar power panels in that they take up approximately ⅓ of the roof space needed for an equivalent size solar power system.

By switching to an energy source that’s clean and green like solar, you can help reduce your carbon emissions and lead a more sustainable lifestyle. Replace your electric water heater with a Solahart, and you could save up to 1.6 to 2.7 tonnes of carbon emissions per year2, which is equivalent to taking a conventional 4-cylinder car off the road.

Why solar power?

Solar power is a great way to reduce your energy bills and your reliance on energy companies by harnessing the sun’s free energy. Australia has the highest uptake of solar globally, with more than 21% of homes with rooftop solar PV. As of 30 September 2020 more than 2.56 million rooftop solar power systems have been installed across Australia.

For ultimate savings, combine a solar water heater with a solar power system to provide power to your home, and supplement this with a battery system to store free energy you can use at night, or when the sun is not shining. Any surplus power can then be fed back into the grid.

Having both solar technologies could help reduce your reliance on fossil fuels in favour of one of the most abundant, consistent sources of energy we have available: our Australian sun and it works hand-in-hand to deliver maximum savings for you and your family. This is particularly important during these uncertain times, as we spend more time at home.

Get Smart. Get Both.

At Solahart we recognise that solar is a very important investment, that’s why we reward customers who purchase both technologies at the same time with a smart solar package. To find out more visit our promotional page here.

Why Battery Storage?

In most Australian homes with PV, a large proportion of the energy produced by solar power panels is sent back to the grid because it’s generated when it’s not needed, i.e. the middle of the day.

Adding home battery storage to a new or existing solar power system allows you to store your unused energy to use:

  • At night
  • On low sunlight days
  • When utility rates are more expensive
  • During blackouts

Battery storage is a smart way to offset your electricity costs as you maximise your solar energy usage and minimise your reliance on the grid.

So, there it is; your quick guide on the types of solar technology available, which you should start with, and how they work together to deliver maximum savings.

Solahart is the only national company that can provide you with expert advice on all three technologies (solar power, solar hot water and battery storage). With so much conflicting information out there, it’s hard to know where to turn. We are here to make it easy for you to make the right decision with honest, tailored solutions for you and your family.

Looking to get started with solar?

Before going solar, there are some key factors to consider, including your family size, energy usage patterns and large appliances in your home, i.e. dryer, washing machine. Your local Solahart Dealer can assist you in choosing the right solar solution for your home. 

Solahart Dealers can estimate how much you could save with solar, thanks to our proprietary  Savings Calculator. Our Dealers are trained to use the system to take you through some assumptions on your energy usage patterns, understand your needs and consider the site conditions to give you an idea of how much you could save.

To organise a safer home assessment, get in touch with your local Solahart Dealer by filling out the contact form below or calling 1300 721 984.

Solahart Solar-Ready water heater is a smart choice because it provides an immediate solution to your hot water needs right now and also gives you the flexibility to upgrade and save on your energy costs in the future.

Whether you need a simple solution to get back into hot water quickly, a solar water heater from day one, or the option to upgrade to energy-saving solar in the future, you’re in control.

And no matter which option you choose, enjoy the extra peace of mind with a 10-year cylinder warranty.


1: Solahart Warranty Details: 10/3/2 warranty; 10 year cylinder and collector supply, 3 year cylinder and collector labour, 2 year parts supply including labour; applies to a single family domestic dwelling only. All other applications have a 3/1/1/1 warranty; 3 year cylinder and collector supply, 1 year parts supply, 1 year labour.

2: Energy savings of up to 65% shown is based on Australian Government approved TRNSYS simulation modelling of a Solahart 302L and using a medium load in Zone 3 and apply when replacing an electric water heater. Any savings will vary depending upon your location, type of Solahart system installed, orientation and inclination of the solar collectors, type of water heater being replaced, hot water consumption and fuel tariff. Maximum financial savings off your hot water bill are achievable when replacing an electric water heater on continuous tariff. Refer to solahart.com.au for further information.

3: For a Solahart Solar Hot Water system, each STC represents 1 megawatt-hour (MWh) of electricity displaced over a 10 year period. The number of STC’s which may be created for the installation of an eligible solar water heater varies with the size and model of the solar water heater and the region (or zone) in which the unit is installed. The value of an STC is not fixed and varies depending on market factors.
