Do I Need a Solar Battery?

When storage earns its place and when it does not — a straight answer rather than a sales pitch.

The question is when you use electricity

If you are home during the day, you already use much of what you generate and a battery adds less. If the house is empty until six, most of your generation is being exported and a battery changes that picture substantially.

What it does not do

It does not make you self-sufficient, and it will not carry a British household through winter on solar alone. Anyone implying otherwise is selling.

Retrofit or now

Adding storage later is normally possible. Fitting a hybrid inverter now makes it cheaper and simpler when you do, which is often the sensible middle path if you are undecided.

Tariffs change the maths

A time-of-use tariff lets a battery charge cheaply overnight, which can matter as much as the solar. It also depends on tariffs that may not exist in the same form in five years.

Common questions

Should I just get a bigger array instead?

Often a reasonable question. If you export most of what you generate already, more panels add less than storage would.

What does the quote cost?

Nothing, and there is no obligation. The installer provides a free design and written quotation.

Who actually does the work?

A trusted MCS-certified installer covering Cardiff and the surrounding area. Solar Panels Cardiff is a quote service, not the installer, so the work, the price, the certification and the warranties are all theirs.
