Maximising the Benefit of your Solar PV Array, Minimise your Bills

Whether you have an existing solar PV array or you’re considering an installation soon, how you harness the energy generated by your system is key to maximising return on investment.

Lower installation costs and rising electricity prices have led to an increase in viability of solar PV. However, with lessening financial support from the government savings on energy bills are now the primary driver behind an installation.

So, how can you use more of your solar energy?


It sounds simple, but the design of the system influences how a customer can use their yield. Systems installed on a south-facing orientation generate the most electricity. On the other hand, east or west orientations may generate slightly less but result in generation at more usable times.

Solar installers should consider occupancy and usage to design a system that produces when demand is highest throughout the day.


Theory is great, but nothing beats the facts and figures.

Knowing exactly what your system is generating, when it’s generating and when it’s exporting puts you in the best position to maximise consumption. With this data, you’ll be able to justify your daytime usage and set your appliances accordingly.

Installing or adding monitoring to a solar PV array is a must.


Living with solar is a different way of life.

Switching from a traditional mindset of running devices during the evening to running them throughout the day will result in a higher percentage of solar gain that can be harnessed. With this step, it’s important to know what you can use and when (hence the monitoring) and a little trial and error.

Timing appliances to run during the day is the best way to maximise solar utilisation and reduce grid demand. Looking at what devices draw what power and fall within your generation patterns, what devices can overlap and what weather to be expecting should all be factored in. The result is higher usage and more gain.

Battery Storage & Hot Water Diverters

How homeowners can use their solar generation after it’s been generated has plagued solar installers for years. Battery storage and hot water diverters have been developed to combat this dilemma.

Storage solutions enable you to charge your solar energy into a battery that can be discharged throughout the evening. This replaces grid demand almost entirely and eradicates electricity bills. Hot water diverters send excess, unused electricity to heat your hot water tank via an immersion heater.

If you think you have high energy demand or you know you’re exporting lots of your generation, considering a secondary installation might be of benefit.
