Is a 5kW solar system right for you?

Do you have a pool, a dryer, air-conditioning or other appliances which use a lot of energy at your home? Investing in solar panels could be a great way to put renewable energy to work for you. 

We’re here to help you find the right solution to match your needs. On average, we find that a household of four or more people tends to suit a 5kW solar system or larger.

How many solar panels do you need?

The number of solar panels you need depends on a number of factors including your energy needs, your roof space and the type of appliances you use. Here’s a general guide to how many solar panels you could have based on your system size.

A 5kW system is about 19 solar panels.

This would take around 32 square metres of roof space.


A 6kW system is about 23 solar panels.

This would take around 36 square metres of roof space.

Calculate your solar or battery savings...

How much energy you use each day will help determine the right system size for your property. For example, the average household of 2-3 people in Australia consumes around 18 kilowatt hours (kWh) per day. ^

This is the storage capacity of the battery, with a usable value of around 80%. A depth of discharge (DoD) is set for batteries so they’re never fully drained (draining a battery to empty affects their ongoing capacity retention).

Battery storage might not be right for you just yet because customers with system sizes below 5kW generally don’t reap the most rewards from installing a battery. Still keen to see the difference it could make? Just add a battery.

Frequently asked questions

icon_solid_solarpanels

Technically, yes – but practically, no. Or at least not yet. Batteries which are built to store solar energy are not currently designed to allow you to go off grid. To be fully self-sufficient and disconnect from the grid entirely, your solar PV and battery system size would generally need to much larger to ensure it works properly across all seasons. Find out more

icon_solid_smart_tariff

A battery will generally help you to reduce your energy bill. The energy your solar panels generate using the power of the sun is free and the battery will make the most of the way you use this free energy. Changing the way you use energy will have a positive effect on your overall savings. Find out more

icon_solid_fronius-inverter

Maybe for a few hours. A battery can’t generate electricity, it can only store it. If there is no other generation source (e.g. solar, grid or diesel generator) and your battery has been depleted, it can’t provide power until it has been recharged. Find out more

icon_solid_fronius_battery

Yes, you can! This is one of the main benefits of installing a battery system. During the day, your solar panels can generate energy and your battery stores any excess generation you may have until it is fully charged (at battery capacity). Find out more
