How To Use Solar Power During Power Outage

Welcome to a future where the power never goes out. A world where we harness the sun’s energy to light up our homes, power our appliances, and ensure we’re never left in the dark, even during a power outage.

This is the power of solar energy, a resource that’s not just sustainable but also reliable in a crisis. With the rising frequency of severe weather events and increasing power demands, it’s an investment in resilience that’s well worth considering.

You might be here because you’re looking to reduce those hefty electricity bills, or perhaps you’re embarking on a home renovation project and are considering your energy options. Maybe you’re part of the growing global community that seeks sustainable, renewable energy solutions for a greener future.

Whatever your motivation, you’re on the right path. By being here, you’re already taking a step towards understanding and tapping into the phenomenal power of the sun, particularly its utility during those inconvenient and sometimes downright dangerous power outages.

The Vital Role of Solar Energy During Power Outages

Solar energy is a dynamic and powerful resource that can support our everyday energy needs, even in the most challenging of circumstances. To understand how it can help during power outages, we first need to understand how solar panels work.

At the heart of solar energy lies an amazing process. Solar panels, also known as photovoltaic (PV) panels, are designed to generate electricity from sunlight. Each panel is made up of numerous solar cells that contain a semi-conductor material, usually silicon. When sunlight strikes these cells, it knocks the electrons loose from their atoms, and this movement generates electricity. This clean and renewable power source fuels our homes with energy, allowing us to power up our appliances and devices.

Typically, most homeowners have a grid-tied solar system. These systems are connected to the local electricity network. During the day, if your solar system produces more electricity than your home needs, that excess energy is fed back into the grid. At night, the grid supplies your home with power and at other times during the daylight hours when your solar system isn’t producing enough electricity, the grid supplies your home with the balance or power required,. It’s a great way to ensure you’re using renewable solar power to its fullest potential while still maintaining a reliable power supply.

However, when it comes to power outages, conventional grid-tied solar systems have their limitations. For safety reasons, when the electricity network goes down, your solar system automatically shuts off as well. This is to protect utility workers who might be repairing the power lines. As a result, even with solar panels on your roof, you might find yourself without power during an outage. But, don’t worry – there is a solution to this dilemma, and it’s transforming the way we use solar power.

Solar and Battery Storage Systems: A Revolutionary Approach to Energy Management

Enter the Solar and Battery Storage Systems. This innovative set-up takes solar energy usage to a whole new level, offering a significant advantage during power outages. With the addition of a solar battery system to your solar power arrangement, the game completely changes.

Here’s how it works: While a typical solar system generates electricity, the battery storage system stores this energy for later use. So, during the day, your solar panels are not just supplying power to your house, but are also charging your solar battery. This stored energy then comes into play when the sun sets, on cloudy days, or crucially, during power outages.

Imagine never having to worry about your lights going out during a storm again. With a solar and battery storage system, you gain energy independence. Your solar power system doesn’t have to shut down when the grid does. Your stored energy can keep your home running smoothly, reducing your reliance on the grid power and giving you peace of mind during outages.

Key Components to Harness Solar Power During Power Outages

In order to make the most of solar power during a power outage, it’s important to understand the key components involved. There are four main parts: the solar panels, the solar hybrid inverter, the battery storage system, and the automatic changeover switch.

Solar Panels: Your Personal Power Plant

Solar panels, as we have discussed, absorb sunlight and generate electricity. Each panel consists of individual solar cells which work together to convert solar energy into a usable form of power. The quality and efficiency of these panels play a critical role in how much electricity you can generate and subsequently store for later use.

The Solar Hybrid Inverter: From Direct to Alternating

The electricity generated by solar panels is in the form of direct current (DC). However, our homes use alternating current (AC). The solar inverter is responsible for this conversion. During normal operation and a power outage, the inverter also ensures that solar power is directed to your appliances via the AC connection and to your solar battery via the DC connection.

Battery Storage: Your Energy Bank

The solar batteries are where the magic happens during an outage. These batteries store excess energy produced by your solar panels during the day. This energy can then be used when solar panels are not supplying enough power or no power, such as cloudy days, during the night, or during power outages.

The Changeover Switch: Your Safety Net

During a power outage, the automatic changeover switch disconnects your home from the grid and allows you to run off your solar and battery storage system. This ensures your solar power doesn’t feed back into the grid during an outage, which can be dangerous for those working to restore power. It’s a crucial component that allows you to use solar power safely and effectively when the grid is down.

Understanding these components and how they work together during a power outage is key to effectively using your solar power system. With the right set-up, not even a blackout can leave you in the dark.

Understanding the Process: How Your Solar and Storage System Works During an Outage

So, you’re curious about how your solar and storage system responds when the grid power goes out? We’re excited to guide you through this process!

  • Step 1: Detection of a Power Outage
    The moment a power outage happens, your solar and storage system kicks into action. The system detects that the electricity network has lost power.
  • Step 2: Isolation from the Grid
    Safety is paramount in these situations. To prevent sending electricity back into the grid, your solar system will automatically disconnect from the grid. This function is carried out by your homes’ automatic changeover switch.
  • Step 3: Activation of the Solar Battery System
    Now that your home is safely isolated from the grid, the stored energy in your solar battery comes to life. They start to supply power to your home, ensuring a continuous supply of electricity despite the grid outage..
  • Step 4: Power Distribution
    Your solar inverter, responsible for converting direct current (DC) from your solar panels and batteries into the alternating current (AC) your home uses, manages the distribution of this stored power to your essential circuits, appliances and lights.
  • Step 5: Recharging the Batteries
    Even during an outage, your solar panels continue their job when the sun is shining. They keep producing electricity, part of which can power your home directly, and the excess is used to recharge your solar batteries.


Understanding how your solar and storage system works in a grid outage is crucial to appreciate the seamless transition to solar power during these times. Your solar battery system ensures you have access to power, while the safety measures in place protect both you and those working to restore the grid.

How to Maintain Solar Energy Usage During Extended Power Outages

With your solar and storage system, you have a reliable power source during an outage. But how can you maximise this power, especially during extended power outages? It’s all about strategic energy use and prioritising.

Firstly, be conscious about your energy usage. Small acts like turning off lights in unoccupied rooms, unplugging non-essential devices, and keeping the use of high-energy appliances to a minimum can extend the life of your stored power. Energy conservation is your ally during a power outage.

Secondly, prioritise your appliances. Identify which appliances are crucial for your household to function and focus on powering those. This typically includes your refrigerator (for food preservation), modem, a few lights, power circuits and critical water pumps and a small reverse cycle air conditioning unit. By managing your energy usage wisely, you can extend the duration of your stored solar power.

The Importance of Quality Materials and Proper Installation

Investing in a solar and storage system is a significant step towards energy independence and resilience. However, to reap these benefits, the quality of both the components and the installation process is paramount.
