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. ^

Every year. *Calculated using the Home plan (A1) and REBS buyback rate (if applicable). Does not take into account any concessions or rebates.. It assumes 80% of system output offsets electricity use. ^ Source: Synergy solar data and Clean Energy Council data.

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.

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

Here’s a quick guide to some of the technical terms you’ll come across as you explore your options for a solar system or battery.

Alternating current (AC)
This is the type of power used by most of our appliances. If you’re using solar panels or a battery, you’ll have an inverter to change the batter or solar DC power into AC power so you can use it in your home.
Battery
This is an electrochemical device used to store energy for a range of uses – from noisy toys to energy to use in your home. The main purpose of a battery for your home is to store excess solar PV that’s generated by your solar system, so you can use that energy when there’s no sun to power your PV system.
Battery capacity
This is the amount of energy a battery is able to store and deliver in a single discharge. Battery capacity is usually measured in kilowatt hours (kWh) for home batteries.
Charge/discharge rate
This is the rate at which a battery can be charged and discharged. It’s a measurement of power and can be expressed in kilowatts(kW). The higher the charge rate, the faster your battery will be able to charge. The lower the discharge rate, the longer your battery will last but you’ll need to rely on the grid to support larger appliances.
Cycle
This is one sequence of charge and discharge of a battery.
Cycle life
Cycle life has nothing to do with cyclists wearing lycra and drinking lattes at your local café (although keep up the great work if you are one!). Cycle life is the number of charge/discharge cycles a battery can achieve prior to reaching end of its design life which is usually when its capacity is significantly reduced.
Depth of Discharge
This is the level the battery is set to discharge to and is crucial to ensure the longevity of certain battery chemistries. Lithium ion batteries (and some other types) are never fully discharged, because that would have a detrimental effect on the life of the battery. For example, if the depth of discharge was 80%, the battery would shut off and not provide any further power once it reached 20% of its capacity. Older lead acid batteries typically are set to discharge to about 50% and more modern Lithium Ion batteries are able to have much higher depths of discharge up to about 90%. If manufacturers advertise 100% depth of discharge, they usually have a buffer of battery capacity that they do quote on their data sheet.
Direct current (DC)
This is the type of power used by batteries and solar panels.
Energy
You know what energy is – you might feel like you have more of it after that chocolate bar at 3pm. Scientifically speaking, energy is the ability to do work or produce a change over time. It’s expressed in kilowatt hours (kWh).
Inverter
An inverter is a device used to convert direct current (DC) power into applied current (AC) power. Solar panels and batteries use DC power so they need an inverter to convert the power into AC power so that it can be connected to the grid and also used by most of our appliances.
Kilowatt (kW)
This is a unit that power is measured in. See the definition of power.
Kilowatt-Hour (kWh)
This is a unit of measurement for energy. See the definition of energy.
Micro inverter
Micro inverters sound cute – and they’re also really clever. They convert DC power to AC, just like a normal inverter. If your solar panels come with micro inverters, these will be positioned on the back of each panel. These types of inverters can cope in any type of weather condition over a longer time each day. They are most suitable for spaces that have shading issues or have panels facing a number of ways.
Photovoltaic (PV)
In really simple terms, the photovoltaic process turns light into energy. With your solar panels, the PV process turns the sun’s energy into a flow of electrons which can then be turned into a direct current and sent to your inverter.
Power
Power is the rate at which energy is flowing, or the rate at which work is being done. While energy is measured in terms of time, power is not. It’s just expressed in watts or kilowatts (kW).
Renewable energy buyback scheme (REBS)

If you’re eligible, REBS gives you the chance to earn money just for sending any excess solar energy back into the grid. Any money earned will be displayed as a credit on your next bill.

Solar panels
These are panels designed to absorb the sun’s rays as a source of energy for generating electricity. If you’re looking for a solar system for your home, the solar panels will be installed on your roof, in a position that will catch the most sunshine.
String inverter

You know the Christmas string lights that light up as a team – or don’t light up as a team? String inverters work in the same way.

String inverters
You know the Christmas string lights that light up as a team – or don’t light up as a team? String inverters work in the same way. String inverters are the most common type of inverters on the market. They convert almost all of the energy generated by the sun into usable energy and function in a set as series.
Tier 1
This is a scale used to rank solar panel manufacturers on their reliability and economic stability. Tier 1 is the top ranking.
Total Energy Throughout
This is the amount of energy a battery is able to provide over its entire design life. It is calculated by multiplying the usable energy a battery system has by that batteries cycle life. This is an important factor to consider when comparing the upfront cost of different products as it will give a better indication of value for money.

It is usually expressed in megawatt hours(MWh). One MWh is equal to 1000 KWh.

Total energy throughput (MWh) = usable energy (kWh) x battery cycle life / 1000
