Battery storage is one of the best ways to get more value from solar panels, especially for households that use a lot of electricity in the evening. But battery sizing is where many people get stuck.

This blog explains how to choose the right size solar battery for a Newton Abbot home, without overbuying.

What a battery does, and what it doesn’t

A battery:

• Stores surplus solar electricity generated during the day
• Lets you use that energy later, usually evenings and early mornings

A battery does not increase generation. It increases self consumption, which usually improves savings.

The three questions that decide battery size

1) How much surplus solar do you produce?
If your system already uses most of what it generates, a battery may have less to store.

2) When do you use electricity?
Evening heavy households often benefit most.

3) Do you plan to add EV charging or electrified heating?
Future load changes can affect what the right battery size is.

A practical approach that avoids mistakes

For many homes, the best process is:

• Install solar and set up monitoring properly
• Review import, export, and daily patterns
• Size a battery around real data, not guesses

If you already know your usage is evening heavy, you can often size storage confidently at install stage, but it should still be based on a proper assessment. You can also find out about our solar panels here.
