Solar power adoption throughout Canberra has been quite rapid over the past 10 years. With liberal amounts of sunshine, high environmental awareness and an electricity marketplace that continues to evolve, the next question that many ACT homeowners are now posing is should a solar battery be part of my home energy system.
Solar batteries are not just a niche technology and the reservation of early adopters anymore. For a lot of grid-connected residential properties in Canberra, battery storage is becoming a feasible proposition to increase the amount of energy independence as well as deal with the rising electricity prices and make better use of rooftop solar production.
This is a long form guide for Canberra home owners specifically. It explains how solar batteries work, what solar batteries cost at your location, how “payback” is calculated in your case, and when battery storage makes sense without hype, sales pressure or brand bias.
What Is a Solar Battery and How Does It Work?
A solar battery is a home energy storage system that uses the energy produced from any excess electricity at the facility generated by rooftop solar panels during the day, which enables the energy to be used earlier, when solar power production is low or absent.
Instead of exporting unused solar energy to the grid to receive a small administration of feed-in tariff, a battery stores this energy onsite. This stored power can then be used to supply your home during periods of low solar generation- in the evenings, overnight or during times of low solar generation in your region.
How Solar Batteries Store Solar Energy
So, solar panels generate electricity as long as sunshine falls on them. However, most households consume most energy outside of the day’s daylight hours. This mismatch in the generation and consumption is where the battery storage plays its role.
In layman’s words, the process is as follows:
- Solar panels are used to produce electricity during the day
- Household appliances are the first to use solar power
- Apart from these, excessive electricity is utilised and sent to the battery
- The energy stored in this battery is stored chemically
- Stored energy is run off when the home needs to have power later
This cycle repeats daily. Over time, the battery then reduces the dependency on grid electricity by acquiring usage of solar energy from day time to night.
Difference between Solar panel and battery
How solar panels and solar batteries work is very different and at the same time fulfilling.
Solar panels:
- Produce electricity from sunlight
- Only produce power during the day time hours
- Do not store energy
Solar batteries:
- Use electricity for power generation in stored
- Do not have their own power generation
- Supply energy when solar panels are inactive
Panels are the production system – batteries are the storage system. One cannot replace the other, but both form a more flexible home energy set up.
AC coupled vs DC coupled systems (simple explanation)
There are two technical types of solar battery systems in Canberra in general.
DC-coupled systems are those in which the energy is stored directly from solar panels before it is converted into the household AC power. These systems are usually more efficient systems and are often found in new solar installations.
AC-coupled systems are used to store energy after the solar power has been converted to AC. They are usually used when adding a battery in an existing solar system.
For homeowners, the decision often depends on whether a battery is being installed as part of a new solar system or retrofitted to a system that is 20 years old or more.
Why More Canberra Home owners are considering Solar Batteries
Interest in home storage of batteries has accelerated throughout ACT. Several things within the country are driving this shift.
Increasing electricity prices in ACT
Electricity prices in Canberra have trended amazingly morning up, especially for grid energy consumed in the evening. While there has been a decline in solar feed-in tariffs, electricity prices at the retail level are still relatively high.
This pricing gap means:
- Exported solar energy making less
- Imported grid electricity has a higher cost
- Self consuming solar energy becomes more valuable
For a large number of households, batteries provide an opportunity to insure against future price increases for electricity, as opposed to relying exclusively on the electricity feed-in tariff.
Grid reliability, blackout protection
While Australia’s tropical capital city Canberra’s electricity grid is largely reliable, outages happen affected by storms and the risk of bushfires or for infrastructure maintenance. In some configurations, battery blackout can take some backup power and is limited.
For homeowners using their homes as offices or for those who require medical gear even a partial backup capability can be worth it. It’s important to note that not all batteries provide backout protection by default.
Maximising self-consumption
Many houses in Canberra produce more solar energy at or during the day than they consume. Without a battery, with excess electricity there is export to the grid.
Battery storage helps to increase self-consumption by:
- Reducing grid imports
- Utilizing more onsite solar power
- Improving the overall system efficiency
Higher self-consumption doesn’t always equate to faster payback, but does provide more control over household energy consumption.
Are Solar Batteries Worth It Canberra?
Whether solar batteries are “worth it” depends a lot on individual circumstances. Canberra’s climate and household energy patterns and electricity pricing are all factors that contribute to outcomes.
Canberra climate and generation from solar
Canberra experiences:
- High summer solar solar generation
- Decreased magnitude of day during winter
- Cooler temperatures in order to ensure battery longevity
While mechanical production of solar systems is lower in the winter, these systems still do generate valuable amounts of energy year-round. Batteries help to even out seasonal variations by transferring available energy to when it is most required.
Winter vs summer performance
In summer:
- Excess energy is produced by the solar panels
- Batteries are frequently charged during the middle of the day
- Night time control is possible – Night time use can be primarily solar powered
In winter:
- Shorter length of days – this decreases generation
- Batteries may not be fully charged on a daily basis
- Increasing use of grids, even storage
This seasonal difference is normal and must be considered in the context of realistic has in mind their savings every month.
Day daytime Export vs night Night Use
Without having a battery, many households export solar energy during the day and purchase it, at a higher price, during the night. It is on this inconsistency that batteries try to reduce.
However, if a household currently uses a lot of energy in the daytime hours, the fill-in of energy during storage hours may be financially limited.
Who benefits most from battery storage
Solar batteries have a way to make use of:
- Poll Bach CPi Households with high use of electricity in the evening
- Families are home during mornings and nights
- Homes that have electric heating or cooling
- Properties planning long term occupancy
Homes that could have no need to batteries now
Battery storage may not be ideal for:
- Very low-usage households
- Homes with the bulk of day time usage
- Recent solar systems still in an optimal export condition
- Owners who intend to sell on a short-term basis
In those cases, waiting, or preparing for later battery readiness may be more practical.
Solar Battery Prices Canberra What Affects the Price?
Understanding solar battery price Canberra home owners suffer from requires looking beyond the initial sale beyond. A number of variables affect the overall system cost.
Battery size (kWh capacity)
Battery capacity comes in kilowatt extent hours or kWh. Larger batteries hold more energy but cost more as well.
Typical residential sizes are between:
- Small systems – for modest evening use
- Medium averagely family systems
- Rather larger systems for high consumption home
Choosing Size: Choosing the biggest size available is less important than choosing the right size.
Installation complexity
Installation costs are subject to variation in function of:
- Existing configuration of the solar system
- Electrical incentives required | Close cobwebs, improve windows and interior, remove wallpaper, install carpet, allow room assessments.
- Switchboard capacity
- Location of the battery
Homes built with older infrastructure may require more work to bring the house standards up to date.
Inverter compatibility
All inverters do not work smoothly with all batteries. Some systems require:
- Inverter upgrades
- Additional controlling equipment
- Replain hybrid inverter replacements
Compatibility assessments are a major component of proper pricing.
Typical Price Ranges (no exact promises)
While the price varies, it is pretty much in a range at the time for the solar battery systems in Canberra, depending on the capacity and installation requirement. Quoted prices are often inclusive of hardware, installation and commissioning.
Rather than just start looking at lowest upfront cost, homeowners need to look at lifetime value, warranty coverage and system suitability.
Why cheap batteries are: Sometimes, cheap batteries may cost more money in the long run
Lower-priced batteries may:
- Degrade faster
- Have shorter warranties
- Provide the limited expandability
- Lack local support
Over time, these things can surpass the savings made.
Solar Battery Payback Explained to Canberra Homes
Payback is also one of the most misunderstood concepts in the battery storage world.
What Does “payback period” Really Mean
Solar battery payback stands for time taken to be equivalent (energy savings/upfront system cost). With the exception of solar panels, batteries tend to have longer payback periods.
Payback is influenced by:
- Electricity prices
- Household usage patterns
- Battery lifespan
- Export tariffs
Importantly, payback is not the measure of the only value.
Factors that influence payback time
No two Canberra households are alike. Two homes with the same system on them could have vastly different results.
Energy usage patterns
High night time users generally benefit more from storage. Batteries are best value if the electricity grid is expensive.
Feed-in tariffs vs storage
Lower feed-in tariffs make storing energy more relative than exporting energy. With changes in tariff over time, the economics of batteries could improve.
Solar battery payback Canberra homeowners are more likely to discover a gradual, rather than instantaneous payback on their investment so it is important to plan for the long-term.
Types of Solar Battery Systems that are Available in Canberra
Battery technology continues to change and there is more choice for home owners than ever before.
Modular vs Fixed Capacity Batteries
Modular systems:
- Allow capacity to be increased at later time
- Suit staged investment
- Support change when it comes to future household change
Fixed-capacity systems:
- Have set storage limits
- Are often simpler to install
- Suit stable energy usage
Hybrid inverter systems
Hybrid systems are combined systems of solar and batteries. They are used in new installations very often and have streamlined system management.
Considerations for the expandability of the future
The purpose of choosing the battery: Here are some things to keep in mind when selecting a battery:
- Planned charger electric vehicle charging
- Household growth
- Heating and cooling improvements
Even though it might take some time to put a battery in place, it still makes sense to plan a solar system with battery storage in mind to save money in the future.
Can current Solar Systems Add a battery
Many Canberra homes already have rooftop solar installed and many are looking at battery retrofits for their homes.
Compatibility with older systems
The older systems may still support the storage of batteries but the compatibility depends on:
- Inverter type
- System age
- Electrical configuration
A professional assessment is critical before investing in any kind of retrofit.
Upgrading inverters v. replacing inverters
Some ways battery installations require:
- Adding a Separate Battery Inverter
- Replacing the present inverter
- Installing a hybrid inverter
Each of the options has varying cost and performance implications.
