Solar panels are an excellent way to reduce electricity bills and improve your home’s energy efficiency. But a common question for many is: Do solar panels work at night? The simple answer is no—solar panels aren’t generating power after sunset because they require sunlight to function.
However, that doesn’t mean your home needs to fall back entirely on grid electricity. Thanks to the advancement of solar battery storage systems, you can store excess solar energy generated during the day and use it to power your home at night or during power outages.
Do Solar Panels Work at Night?
Solar panels produce electricity only when exposed to sunlight. During the day, your solar panel system collects solar energy and powers your home’s appliances. Any excess electricity not used immediately is either sent back to the grid or stored in your battery.
When night falls, your solar panels aren’t generating, but a solar battery system ensures that your home continues to operate using energy generated earlier. This seamless transition is a key reason more people are choosing to add a battery to their existing solar power system.
How Do Solar Batteries Work?
Solar and battery systems work together to maximise your energy independence. Here’s how the battery system works:
-
During the day, electricity generated by your solar panels is used by your home.
-
Excess power is used to charge the battery.
-
At night or during outages, your home draws battery power instead of relying on the grid.
These systems help store energy for use later, making your solar PV system more versatile. Lithium-ion batteries—commonly used in home setups—work through a chemical reaction to store and discharge energy efficiently.
Benefits of Solar Battery Storage in Perth
Investing in solar battery storage Perth delivers key benefits:
-
Energy independence: Use your solar electricity when the sun isn’t shining.
-
Reduced energy bills: Avoid high evening tariffs by using stored energy.
-
Reliable backup: Maintain power to critical appliances during a power outage.
-
Environmental sustainability: Reduce reliance on electricity from the grid, cutting down fossil fuel use.
Whether you have a new solar setup or an existing solar system, a solar battery can power your home efficiently, day or night.
Choosing the Right Solar Battery System
When choosing a solar battery for home Perth, consider:
-
Battery size: Battery size is measured in kWh and should match your usage.
-
Cycle life: The number of times a battery can charge and discharge.
-
Battery inverter compatibility: Some setups need an AC-coupled battery system, while others may use a hybrid inverter.
-
Expandable storage: Modular storage systems allow you to increase capacity as your needs grow.

Can I Add a Battery to an Existing Solar System?
Yes, you can. If you have an existing solar system, adding battery storage is a great way to upgrade your setup. Our team can assess your current solar PV and recommend whether a battery to an existing solar system is feasible, or whether a system reconfiguration is needed.
Common Types of Batteries for Home Use
The most commonly used batteries are lithium-ion batteries. They are known for high energy density, long cycle life, and efficiency. Types of lithium-ion batteries include LFP (Lithium Iron Phosphate) and NMC (Nickel Manganese Cobalt), both widely used in home energy storage applications.
