Frequently Asked Questions
What is battery storage, and how does it work?
Battery storage allows you to store excess energy produced by your solar panels in rechargeable batteries for later use. In Western Australia, where solar panels can produce more energy than you might need during the day, battery storage can save that extra power for nighttime or cloudy days when solar isn’t being generated. This stored energy provides a backup during peak demand times, ensuring you have reliable power even when the sun isn’t shining.
What types of batteries are commonly used for energy storage?
The most commonly used batteries for home solar energy storage in WA are lithium-ion, lead-acid, and flow batteries. Lithium-ion batteries are especially popular in residential settings due to their high energy density, efficiency, and long lifespan, making them ideal for homes and businesses looking for reliable storage.
Can I run my house on solar battery power only?
Yes, it’s possible to run your home on solar and battery backup power alone, though the specifics depend on your energy needs, the size of your solar system, and the battery capacity.
How long can a solar battery power my home?
The duration a battery can power your home depends on its size, your energy usage, and whether it’s recharged by solar during the day. In Western Australia, homes typically need a battery large enough to last through overnight hours and potentially cloudy days. Some batteries can also recharge with any available sunlight, even during a grid outage.
Can the batteries charge at night?
No, batteries charge directly from solar panels, so they only charge during the day when there’s sunlight. However, a fully charged battery can provide stored power for evening and nighttime use.
How much would it cost to run on solar battery only?
The cost of going solar battery-only varies widely and depends on factors such as your household’s energy consumption, battery type and size, solar system size, and local sunlight hours in WA. It can be expensive initially, but energy savings may make up for the cost over time.
How long will the solar batteries last?
Most solar batteries last between 5 to 15 years, depending on the type, usage, and local climate conditions. Lithium-ion batteries, which are popular in WA, tend to have a longer lifespan, especially with regular maintenance.
What size battery system do you need?
The right battery size for your home depends on how much energy you use at night. The average Australian home uses 16-20 kWh in a day, with over 60% of that used after sunset. For a typical household, a 10 kWh battery is a good starting point to cover nighttime energy needs. To keep it reliably charged, you’d also need at least 10 kW of solar panels to produce enough energy throughout the year.
How do solar batteries save you money?
Solar batteries store extra energy from your solar panels during the day, allowing you to use this “free” solar power at night. Instead of paying to draw electricity from the grid after the sun goes down, you’re using the energy stored in your battery. With a big enough solar and battery setup, you could potentially avoid electricity bills altogether, with only minimal grid usage and the savings from selling any extra solar energy back to the grid helping cover your daily service charge.
How much space does a battery storage system take up?
The space needed depends on the size of the battery system. For a residential setup in WA, most systems are compact enough to fit in a garage, utility room, or a shaded outdoor area. Larger commercial battery systems, however, require more space, so available area is something to consider when choosing your battery system.
