Battery vs Solar: What's the Difference?
Battery vs Solar:
Solar panels generate electricity, while batteries store electricity for later use. Understanding the difference can help you decide whether you need solar, battery storage or a combination of both.
Solar panels and home batteries are often discussed together, but they perform completely different jobs.
Solar panels generate electricity from sunlight.
A battery stores electricity so that it can be used later.
Understanding this difference is important when deciding what type of home energy system is right for you.

Battery vs Solar What do They Do?
- Solar panels generate electricity when they receive daylight.
The panels produce DC electricity, which is converted into AC electricity by an inverter so it can be used within the home.
Solar generation is normally highest during the middle of the day, although actual production depends on factors such as weather, season, orientation, panel angle and shading.
The main purpose of solar panels is to generate electricity.
Key points:
• Generates electricity from sunlight.
• Produces electricity mainly during daylight hours.
• Generation varies throughout the day and across the seasons.
• Can reduce the amount of electricity purchased from the grid.
• Can potentially export surplus electricity to the grid.
• Can be combined with battery storage.
What Does a Battery Do?
- A battery does not generate electricity.Instead, it stores electricity so that it can be used later.A battery can potentially charge using surplus solar generation or, where supported, electricity from the grid.It can then discharge electricity when the home needs it.The main purpose of a battery is to store and manage electricity.Key points:• Stores electrical energy.• Can store surplus solar electricity.• Can potentially charge from the grid.• Can supply electricity later when required.• Can help reduce electricity purchased during expensive periods.• Can work alongside time-of-use electricity tariffs.
UK Power Tech Hub Takeaway
Solar panels generate electricity.
Batteries store electricity.
Solar can reduce the amount of electricity you need to buy from the grid, while a battery can help you use electricity at a different time from when it was generated or purchased.
If you are deciding between the two, start with your electricity usage and what you are trying to achieve rather than simply choosing the biggest system available.
