When you’re comparing solar quotes, it’s easy to focus on kilowatts and rebate amounts. But  solar panel size, dimensions and weight  quietly decide whether a system actually suits your roof, how it will look, and how simple the installation will be. For Australian homes, those details matter just as much as the brand badge on the panel. Drawing on leading Australian guides and Solar National’s on-roof experience, this article breaks down what “size” really means, typical  solar panel dimensions  and  solar panel weight  in Australia, and how to match them to your roof. What does “solar panel size” actually mean? Online,  solar panel size   is used in two ways: Electrical size (wattage)  – 370W, 400W, 440W, etc. Physical size (dimensions and weight)  – length, width, thickness, and kilograms. Most modern residential panels in Australia sit in the  370–440W  range, but the physical footprint doesn’t change as much as you might...

  Australia’s uptake of rooftop solar has made us world leaders in distributed renewable energy.  Many households are now looking beyond panels to  solar battery installations  to increase self‑sufficiency, reduce bills and improve resilience during blackouts.  Yet the simple question “how long can a solar battery power a house?” has no one‑size‑fits‑all answer. Runtime depends on battery size, household consumption, how you use your system and whether solar panels are available to recharge the battery. This article draws on independent research and government guidance to explain the factors that determine battery runtime and to help you choose the proper storage solution. Understanding battery capacity and household consumption The ability of a battery to keep your lights on is governed by its capacity, measured in kilowatt‑hours (kWh). One kWh represents the amount of energy required to run a 1 kW appliance for one hour. An article on battery sizing notes ...

  Homeowners and businesses across Australia are increasingly pairing rooftop solar panels with energy-storage batteries. A solar battery stores surplus electricity produced during daylight hours for use later at night or during an outage. It gives property owners more control over the electricity they generate, reduces reliance on the grid, and can even provide income through feed-in tariffs or virtual power plant (VPP) schemes. However, batteries are not without drawbacks. They involve a significant upfront cost, and their environmental footprint depends on how they are manufactured and recycled. This article from  Solar National  looks at how solar batteries work, the main types available, the advantages and disadvantages of installing one in a Sydney home, and answers frequently asked questions. It draws on independent research and government information from 2024–2025 to help you decide whether a solar battery is right for you. How a Solar Battery Works A solar batt...

  The solar inverter market in Australia is heating up — and not from the sun. In 2025, both  Sungrow  and  SolarEdge   have rolled out aggressive trade-in programs offering households rebates and tech upgrades. These aren’t just discounts—they’re incentives for Australians to modernise their energy setups with hybrid inverters and battery-ready systems, while responsibly disposing of aging hardware. Sungrow claims over  400,000 residential systems   installed across Australia, while SolarEdge offers up to  12-year warranties  with their trade-up plans. Whether you’re looking to upgrade, improve backup capabilities, or align with energy providers’ new phase balancing rules, this guide breaks down everything about both offers and what they really mean for your home—and your wallet.

  In September 2025, the Australian Competition and Consumer Commission (ACCC) officially announced a safety recall for certain GoodWe EHB series and GE branded GEH series hybrid inverters sold across Australia. The root of the issue lies in a bypass‑switch bug: when the inverter is placed in “bypass” mode while operating in backup mode, it can continue exporting power to the grid. In the event of islanding (i.e. the grid is down), this raises a serious risk of electric shock to workers or consumers. This recall again highlights that even well‑regarded solar inverters like GoodWe are not immune to design or firmware flaws. If you own a GoodWe or GE hybrid inverter, it’s essential to act quickly, check your firmware version, and avoid using the bypass switch until the fix is confirmed. In this article, we’ll break down what’s going on, what common GoodWe inverter problems look like, and what steps you should take now to protect your system and your safety. What Models Are Affecte...

  As the push for clean energy solutions continues to gain momentum across Australia, solar batteries have become an essential part of many homes and businesses. Among the most popular options is the  Tesla Powerwall 2 , a home battery system that stores energy from solar panels for use during the night or in power outages. However, recent news has caused concern among Australian consumers. Tesla has issued a recall for some  Powerwall 2  units due to safety risks. In this blog, we’ll explore what we know about the recall, the potential risks, and how you can protect your investment in solar energy. What Is the Tesla Powerwall 2? Before delving into the recall specifics, let’s quickly review what the  Tesla Powerwall 2  is and why it’s so widely used . The Powerwall 2 is a lithium-ion battery storage system designed to store excess energy generated by solar panels. This allows homeowners to have access to renewable energy even when the sun isn’t shining. I...
