Reduce Your Energy Bills


Advances in solar capacity and capability are constantly growing, and they can come from unexpected sources. A great example is Electric Vehicles (EV) and the impact their design and popularity have had on battery storage systems.

What does that have to do with Solahart Wollongong and solar power to the Illawarra region? Home battery technology provides homes and businesses with 24/7 access to their solar power, that’s something we are definitely on board with.

One of the traditional drawbacks of solar energy is that it needs to be used instantly. While excess solar power can easily be sold back to the grid, it’s not at the same rate that you are paying for your evening household electricity.

Solar battery storage allows you to store excess solar energy instead of selling it back to the grid. This is the perfect solution for times when solar energy is limited due to storms, cloud cover, mist or rain, as well as in the evening and overnight when solar is not available.

This has a significant impact on your energy bills as you will no longer be dependent on peak rate electricity. Energy companies charge higher rates (as much as 32%) for afternoon and evening electricity use, typically between 5 pm – 9 pm.

If you don’t have solar, or not enough to fully charge your battery, you can opt to charge up during off-peak rates, and use stored energy during peak times.

Battery storage is now reliable, affordable and maintenance-free with slim and sleek battery packs that can be neatly mounted to a wall to significantly reduce your grid energy costs, or even get you off the grid entirely.

Excess energy harvested from your solar panels can be sent back to the grid, but this is at a low tariff because it’s the same time that other solar excess is entering from neighbours as well as low energy demands in general.

When you are switching on grid power in the evening, you are paying peak energy rates that will outstrip your grid credit.

Home battery storage, like the SolarEdge Energy Bank, gives you the ability to extend how far your solar energy takes you to maximise your solar value and minimise your energy bills.
You can use the excess energy from your solar to charge your battery and power your home:

● In the afternoon, evening and night
● During blackouts
● When sunlight is limited due to poor weather
● During peak energy torrid time periods

This gives you round-the-clock access to solar for your Wollongong, Shellharbour, Kiama and Helensburgh home that would otherwise be limited to strong sunlight hours.


Solar battery storage solutions work in a number of ways to reduce your reliance on peak grid electricity and give you better returns on your solar energy

● Collect excess energy from your solar panels and store it for later use
● Give you access to energy when the solar is not able to supply enough power
● Collect off-peak energy from the grid for storage
● Use off-peak energy during peak-rate times
● Provide backup power from the battery in the event of a blackout
● Record your energy consumption rates and usage patterns for analysis, feedback and programming recommendations

Different types of batteries will function a little differently, depending on the brand and style.
Most are Lithium-ion batteries, charging on a Direct Current (DC) to provide anywhere between 9.7kWh and 29.1kW of usable energy.

While you can choose to convert stored solar energy when solar is low, you can also store and keep energy for emergencies, such as during blackouts.

Solahart experts can give you advice on the best battery choice for your needs and explain the direct benefits and use for your home.


What are the benefits of solar battery storage?
Your solar battery storage solution reduces your dependence on the energy grid by providing reliable power to your home no matter the weather or time of day.

Even without a solar system, you can charge your battery at off-peak grid energy times to reuse at peak times or when there are blackouts or power failures.

Battery storage are smart technology systems giving you access to detailed information about your energy consumption, capabilities and daily patterns and track your battery use in real-time. The onboard computer can use this information to provide the best use of your stored energy, or can give you direction to set your own programs to harvest and use energy exactly to your personal requirements.


Solahart Wollongong gives you a wide range of battery choices. We provide a large range of units and brands to suit different needs as well as affordable options that tackle excess solar power a little differently with our Solahart PowerStore.
