How solar power works

Solar power systems generate electricity from sunlight, using solar panels made up of many photovoltaic (PV) cells that collect the light from the sun and convert it to DC current.

The DC current is then is fed through an inverter and turned into usable electricity (240V AC) to power your home, greatly offsetting your electricity costs by minimising the amount of power you consume from the grid. The amount of electricity you produce depends on the number of panels you install, their efficiency, the size and quality of the inverter, the orientation of your roof and the amount of sunlight available in your location.

Your home remains connected to the power grid so that when you generate more electricity than you can consume, you can feed it back into the grid. You will also be able to purchase electricity from the network when the sun is not shining or when your system is not producing enough to meet your requirements.

Solahart Solar Power

We have a range of solar power systems available to suit your needs; including our own Solahart Silhouette panels with all-black stylish appearance, world-class inverters and energy storage solutions that are second to none.

We have a range of solar panels to suit your needs, including our Solahart Silhouette panel with an all-black stylish appearance and an Australian 25-year Solahart Product Warranty, and our Solahart SunCell panel, offering great value for money. Ask us about our range.


Introducing the latest Solahart Silhouette solar panels with an Australian 25-year Solahart Product Warranty

The new ultimate-performance Solahart Silhouette panel, with stylish all-black appearance, is the ideal solution for Australian homes thanks to its innovative and premium cell technology.

The new zero-gap layout boosts panel efficiency to up to 19.8% and because they’re from Solahart, Australia’s trusted name in solar for over 65 years, they come with an exceptional 25-year Australian Solahart product warranty, so you can be sure of worry-free, trouble-free energy for years to come.

Designed in Germany and built to withstand the harshest Australian conditions ensuring an incredibly low rate of panel degradation. In fact, their output is guaranteed to be at least 86% of the nominal power for up to 25 years, which means you’re sure to enjoy energy free from the sun, for years to come.

The rear surface of every cell within a Solahart Silhouette has been treated with Passivated Emitter and Rear Cell (PERC) technology so that they work like household mirrors. Rays of sunlight that would otherwise be wasted reflect through the panels to generate more electricity and increase your panels’ efficiency per surface area. This guarantees high performance under real conditions, with exceptional low-light and high-temperature behaviour. This means high yields are produced throughout the day, even in periods of low radiation intensity including early morning and late afternoon; and even on hot days, these panels produce more reliable yields than standard solar power panels. 

Solahart SunCell solar panels
High-efficiency panel technology offering great value for money

The new high-performance Solahart SunCell panel is not only great value but is also custom designed and built to Solahart’s strict specifications.

With innovative half-cell technology and excellent power efficiency that results in more energy production per square metre, Solahart SunCell ticks all the boxes on durability and has passed endurance testing for up to three times more cycles than the international standard, which makes it an ideal solution in Australia’s harsh conditions.

Manufactured to specification, these panels are only available through Solahart and come with a 15-Year Solahart Product Warranty for ultimate confidence and peace of mind.

Our Inverters

Inverters are considered to be the 'brains' or the engine room to your solar power system. Their primary function is to convert the direct current (DC) output into alternating current (AC). AC is the standard used by all home appliances.

Your inverter needs to provide efficiency and reliability so you can get the most power out of your PV system. That's why Solahart only selects inverter suppliers that we can trust.

Before releasing new models into our product range, we thoroughly check certifications and performance data from the manufacturer and perform our own field tests to ensure quality and reliability. Plus, all our inverters come with a Solahart Warranty – for extra peace of mind.

Energy Storage

In most Australian homes, 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. However, 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.

Residential battery storage solutions to suit your needs

When combined with a new or existing solar power system, batteries allow you to maximise the use of your solar power by storing excess electricity produced during the day for use at any time.

You can reduce your reliance on power from the grid and lower your power bills even more.

Solahart can help you choose the configuration that best suits your needs.

Batteries in our range include:

  • Tesla Powerwall 2
  • Goodwe battery
  • SolarEdge Energy Bank battery

Solahart PowerStore also fits into the Energy Storage category.

Home Energy Management Systems (HEMS)

Installing solar technology is a smart way to reduce your energy costs and create a more sustainable lifestyle. And now, you can get more out of your solar system by making it even smarter with a Solahart Home Energy Management System (HEMS) that brings your connected appliances and energy-generating devices together under one monitoring and control platform.

Did you know?

Water heating is the second largest household energy user comprising approximately 25% of the average Australian household’s energy use*.
So, when it comes to selecting solar technology, it makes sense to start by reducing the amount of energy required by your home by installing a solar water heater.

The great thing about heating your water with the sun is that you will also be helping the environment. Did you know that a Solahart solar water heater can help you save up to 1.6 to 2.7 tonnes of carbon emissions per year? 

Compared to solar power panels, solar hot water technology uses collector panels that are much more efficient per square metre. In fact, solar water heater collectors take up about ⅓^ of the roof space needed for a PV system that would produce an equivalent amount of energy. So, if your roof space is limited and you’re looking to maximise your solar production, choosing a solar water heater makes a lot of sense.
