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.

Solahart’s 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 have become a world leader in the field of solar energy.

Today our solar power PV systems are among the most efficient in the world, offering big energy savings to homeowners who switch to solar panels and energy free from the sun.

Our Solahart Experts are qualified to assess your home and provide you with the best systems to meet your family’s needs. Our installers are trained to the highest standards 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.

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.
