Discover how the electricity your solar panels generate is used, where surplus energy goes, and how battery storage helps you make the most of every kilowatt.

Solar panels can generate a surprising amount of electricity throughout the day, but many homeowners don’t realise that not all of that energy is used immediately. Depending on how much electricity your home is using at the time, surplus energy may be exported to the National Grid or stored for later use with a home battery.

Understanding where your solar energy goes is key to getting the most from your renewable energy system.

As your solar panels generate electricity, your home uses that energy first. Lighting, kitchen appliances, televisions, home offices and electric vehicle chargers can all run using renewable electricity as it’s produced.

The more electricity you use while your panels are generating power, the less you need to import from the National Grid, helping reduce your electricity bills.

On sunny days, solar panels often generate more electricity than your household needs. Without a home battery, this surplus electricity is automatically exported to the National Grid.

Many homeowners receive payments through the Smart Export Guarantee (SEG), but once your electricity has been exported, it is no longer available for your own home.

If your home has battery storage, excess solar energy can be stored instead of being exported. Later, when the sun goes down and your panels stop generating electricity, your home can draw power from the battery before importing electricity from the grid.

This helps increase self-consumption and reduces reliance on your energy supplier.

Battery storage allows homeowners to keep more of the renewable electricity they generate, making better use of their investment in solar panels.

For many households, this means lower electricity bills, greater energy independence and better control over when and how electricity is used.

Why do solar panel owners still receive electricity bills?

Because most homes use electricity after sunset. Without battery storage, that electricity needs to be imported from the National Grid.

Do I get paid for exporting electricity?

Many UK energy suppliers offer payments through the Smart Export Guarantee (SEG), although export rates are usually lower than the price of buying electricity from the grid.

Can battery storage eliminate my electricity bill?

Not completely. However, it can significantly reduce the amount of electricity you need to buy by storing excess solar energy for later use.

Is battery storage worth it?

For many households, battery storage improves self-consumption, reduces reliance on the grid and helps maximise the value of a solar PV system.
