Solar batteries are quickly becoming one of the most popular upgrades for Australian homes with rooftop solar. With electricity prices rising and new battery incentives available, many households are asking the same question:

What size solar battery do I actually need?

Choosing the right battery size matters. Too small and it may run out before the night is over. Too large and you might pay for storage capacity you rarely use.

The ideal battery size depends on several factors including your household energy usage, the size of your solar system, and whether you plan to power things like electric vehicles or backup circuits during blackouts.

This guide breaks down the key things that influence battery sizing so homeowners can make a more informed decision.

If you’ve started exploring solar for your home, you may have already noticed something surprising: solar quotes can vary a lot.

It’s not uncommon for homeowners to receive three quotes for what seems like the same system and see prices ranging from several thousand dollars apart. Naturally, this raises questions. Is someone overcharging? Is someone cutting corners? Or are the systems actually different?

The truth is that a solar system isn’t a single product like a television or a fridge. It’s a combination of equipment, design, installation quality, and long-term service. Each of these factors can influence the price of a quote.

Understanding these differences helps homeowners make better decisions and focus on the factors that actually affect the long-term value of a solar system.

If you’ve started looking into home batteries, you’ve probably seen the terms “AC-coupled” and “DC-coupled” thrown around like everyone should already know what they mean. Totally fair if it sounds like electrical jargon, because it is.

The good news is the concept is simple once you picture how electricity flows through a home. In this guide, we’ll explain AC vs DC coupling in plain English, why it matters for performance and upgrades, and how to choose the right setup depending on whether you already have solar or you’re starting fresh.

As more Australian households embrace solar, one question comes up more often...

What actually happens to solar panels when they reach the end of their life?

It’s a fair question. With millions of rooftop systems now installed nationwide, understanding how solar panels are reused, recycled, or regulated at end of life is an important part of the clean energy story.

The short answer is this: solar panels don’t simply become waste. Australia is actively building systems to manage panel reuse and recycling, and policy is evolving to support a more circular solar industry, aligning with global best practice.

Here’s how it works.
