  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...

  Choosing the right solar battery can make all the difference in how much value you get from your solar system. With electricity costs climbing, more Australians are turning to battery storage to maximise savings and ensure backup power when it’s needed most. A good solar battery comparison usually comes down to a few key factors: capacity (kWh), depth of discharge (DoD), cycle life, efficiency, warranty, and cost. Lithium-ion options, especially LiFePO₄ batteries, have become the most popular because they offer long lifespans and safer performance. Meanwhile, modular batteries give households the flexibility to expand storage as energy needs grow. When weighing up options, it’s also important to consider whether your goal is to cut bills, increase energy independence, or have reliable backup power during outages. Each brand and model brings different strengths—some excel in affordability, while others focus on durability or higher storage capacity. At Solar National , we help h...

  Powering your home when the sun goes down requires more than just solar panels. The right battery system lets you store sunshine for later, cut bills and keep the lights on during outages. This guide compares popular solar batteries available in 2025, explains different battery chemistries, outlines government rebates and helps Australian households decide which storage solution is best for them. Why consider a solar battery in Australia? Australia’s love affair with rooftop solar continues. By mid‑2025, more than 3.5 million homes had solar panels and many households were exploring batteries. Several factors make 2025 a particularly attractive time: Rising electricity prices and shrinking feed‑in tariffs:  Day‑time export rates have fallen below $0.05 per kWh in some states, reducing the return from sending solar back to the grid. Using a battery to self‑consume solar generation protects households from higher retail tariffs. Cheaper Home Batteries Program:  The fede...

When investing in solar technology, the choice of battery is only part of the equation. Solar battery placement is just as critical to ensure efficiency, safety, and long-term performance. For Australian households and businesses, where and how the battery is installed can make the difference between reliable clean energy and a system that underdelivers. At Solar National , we guide our customers through both the selection of the right solar battery and its ideal placement for maximum returns. Why Solar Battery Placement Matters Batteries are sensitive to their environment. Factors such as temperature, humidity, and airflow directly influence their performance and lifespan. Poor solar battery placement can lead to overheating, reduced storage efficiency, and costly replacements.  Best Locations for Solar Battery Placement 1. Garage or Utility Room The garage is one of the most popular spots for solar battery placement in Australian homes. It offers: Protection from harsh weather ...

As homeowners in Sydney and its surrounding suburbs look to utilize the power of the sun, understanding solar panel efficiency becomes crucial.  Solar panels  are a fantastic investment, but not all panels are created equal. Efficiency ratings play a significant role in determining how well your solar system will perform over time. This article will explore how these ratings affect solar panel performance, helping you make an informed decision for your home. What is Solar Panel Efficiency? Solar panel efficiency refers to the percentage of sunlight that a solar panel can convert into usable electricity. For example, if a panel has an efficiency rating of 20%, it means that 20% of the sunlight hitting the panel is transformed into energy. The higher the efficiency, the more electricity you can generate from the same amount of sunlight, which can lead to lower energy bills and a quicker return on your investment. Understanding Efficiency Ratings Efficiency ratings are typically ...

  Choosing the right location for your solar battery is crucial not only for safety but also for optimising the performance and lifespan of the system. Where solar energy adoption is on the rise, finding the best spot to install your solar battery ensures you get the most out of your investment. This guide will explore the factors to consider when selecting the ideal location for your solar battery, highlighting both indoor and outdoor options, and addressing common concerns. 1. Compliance with Battery Installation Standards When installing a  solar battery  , location choice isn’t just about convenience—it’s a regulatory issue. Installers and homeowners must comply with the current standard for battery systems in Australia. This guideline outlines acceptable zones, restricted areas, and minimum clearances from habitable spaces, windows, and ignition sources. Additionally, the  Clean Energy Council (CEC)  provides technical guidelines that align with most manufa...
