Solahart’s High Performance Solar Power Systems

Solahart was one of the first companies in the world to recognise the value of the sun’s free energy.

We pioneered solar water heating in Australia in 1953. Since then we have installed over 1 million systems in over 70 countries and over half a million solar power panels.

Our extensive network of Solahart Experts is qualified to assess your home and provide you with the best solutions to meet your family’s needs. Our installers are trained to the highest standards with Clean Energy Council (CEC) accreditation, and every Solahart dealer is part of the CEC retailer code of conduct scheme, to ensure the safety and effectiveness of your system.

All this is backed by our comprehensive warranties and the peace of mind you’ll get from dealing with Australia’s solar pioneer.


Introducing Solahart Silhouette Solar Power Panels


Solahart Silhouette Solar Power Panels are the perfect choice for Australian homes.

Their stylish, all black appearance is designed to complement contemporary roofing designs while advanced cell technology and superior ‘low-light’ and ‘high-heat’ performances result in a consistently high yield.

And because they’re from Solahart, Australia’s trusted name in solar for over 65 years, you can be sure of worry-free, trouble-free energy for years to come.



Solahart Silhouette Solar Power Panels feature Australian-designed PERC (Passivated Emitter and Rear Cell) monocrystalline cell technology which generates high yields per surface area. This guarantees high performance under real conditions with exceptional low-light and high-temperature behaviour. High yields are produced throughout the day, even in periods of low radiation intensity including early morning and late afternoon. Even on hot days, these panels produce more reliable yields than standard solar power panels.



The rear surface of every cell within the Solahart Silhouette Solar Power Panel is treated with PERC technology so that they work like household mirrors. Rays of sunlight that would otherwise be wasted are reflected through the panels to generate more electricity and increase your panels’ efficiency.

Unsurpassed Attention to Detail


For your ultimate peace of mind, Solahart Silhouette Solar Power Panels go through four levels of quality testing before they get to you. We start with IEC Certification, an internationally recognised panel check. Panels are then quality tested through VDE, an independent authority considered the gold standard for European auditing and testing authorities.

Further testing continues in both regular Factory Quality tests, and the Solahart Quality Program, developed by Solahart R&D in Australia. These tests include an analysis of Solar Panel electrical data and checks for micro-cracks to ensure your panels are problem-free and deliver all the power you’ve purchased.


Solahart Silhouette Solar Power Panels are designed in Germany and built for the harshest Australian conditions. Their world-class build quality ensures an incredibly low rate of panel degradation. In fact, their output is guaranteed to be at least 83.6% 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.


At Solahart, we go to extreme lengths to guarantee the safety and reliability of every system we sell.

Our Solahart Silhouette Solar Power Panels are tested by the Cyclone Testing Station at James Cook University in Townsville and are capable of withstanding cyclonic wind loads in all regions of Australia. They’re even strong enough to survive cyclones similar to Cyclone Larry in 2006, and Cyclone Yasi in 2011.

How Solar Power Systems Work

Solar PV systems generate electricity from sunlight. The solar panels are made up of many photovoltaic (PV) cells which collect the light from the sun and convert this into DC current. This is fed through an inverter and converted to 240V AC to power your home. The amount of electricity you can produce depends on the number of panels and their efficiency, the size of the inverter, the orientation of your roof and the amount of sunlight in your location.

Your home remains connected to the power grid so that when you generate more electricity than you need, you can feed it back into the grid. Alternatively, you can purchase more electricity from the grid when the sun’s not shining or when your system is not producing enough to meet your requirements.

Did You Know?

Water heating is a significant user of energy in Australian households; approximately 25 per cent of household energy use in Australia+. In fact, water heating is the second largest segment of household energy use, after space heating and cooling. 

Installing a solar power (PV) system can reduce the amount of energy you buy from the grid to provide hot water. But, did you know that a solar water heater uses up to 50%-90%* less energy than a conventional electric water heater? Many Solahart customers have found that installing a solar water heater allows them to substantially reduce their energy consumption before they install Solar Power.  In most cases this means they can install a smaller Solar Power system because their household energy use is lower with a solar water heater than without one.

The great thing about Solar Water Heaters is that they store energy free from the sun in a tank for later use, which is in effect, just like a battery. Because they are so efficient, Solar Water Heater collector panels take up about 1/3** of the roof space needed for an equivalent sized PV system.

What's right for me?

If you’re keen to reduce your energy use with solar power, then there are a few things worth considering.

Your Daily Power Usage Patterns

It is important that we install the PV system that best suits your needs. By looking at your recent power bills, your Solahart Expert will understand your daily power usage patterns and size the system that maximises savings. Further savings are possible by adding a Tesla Powerwall battery to store free power for use at night or when the sun’s not shining.

Your Roof Space and Orientation

Our smallest PV system needs just 10m² of roof space to generate around 30% of the average Australian household’s energy use. Larger systems will require over 30m² of roof space however they have the potential to significantly reduce your reliance on the grid. In Australia, PV systems are most efficient when installed on a North facing roof and as you move away from North the efficiency of the system is reduced.

*Energy savings of up to 50% to 90% shown are based on Australian Government approved TRNSYS simulation modelling using a medium load. Savings and incentives 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 for further information.

**Calculation based on comparing the STCs for a 272MLV to a 2kW PV system in zone 3, adjusted for a 10 year deemed period.
