How to Use Solar Panels During A Power Outage in UK

home power outage

In recent years, the United Kingdom has experienced an increasing frequency of power outages, driven by a variety of factors such as extreme weather events. As a result, individuals and businesses are exploring alternative energy solutions to maintain power during unexpected outages.  With the declining cost of solar panels, an expanding number of households can now enjoy savings of hundreds of pounds on their electricity bills for decades to come. How to use solar panels during power outages in UK? We will delve into the operation of solar panels during power outages in the UK in this detailed article, studying both off-grid and on-grid systems, explaining the constraints, and offering insights into effective utilization.

Do Solar Panels Work in A Power Outage in the UK?

Do solar panels work in a power cut in the UK? Most people question if solar panels work when the power goes out. Solar panels alone will not function during a power outage because electricity can only be stored in batteries. During a rolling power cut, if you have solar battery storage, you may quickly recharge it with solar energy and utilize it to power appliances. Only if your installer configures your solar panels to function during a power outage will they be able to do so.

The majority of solar panel systems will shut off automatically during a power outage. Still, your installer can add a relay to the system to allow it to transfer energy from your solar battery to your house during a power outage at an extra expense. If you remove this extra feature during a power outage, neither your battery nor your solar panels will be able to provide any electricity to your house.

Off-Grid Solar Panels:

Off-grid solar systems allow you to live without relying on the utility company for energy and instead use your energy source. You can use a BLUETTI Solar Generator Kit to harness solar energy and power your home appliances. 

You don't have to worry about a rolling blackout or paying a high energy bill to the utility company if you live off the grid. Off-grid solar systems are also environmentally friendly because they emit no emissions. The first step towards becoming self-sufficient and independent is to begin using your energy. However, living an off-grid existence is not easy. Before you can live an off-grid existence, you must first organize everything, make preparations, and conduct extensive research.

On-Grid Solar Panels:

Installing an on-grid solar system means that regardless of how much power your system produces or whether you have batteries, you will always have access to electricity (until the grid goes down).

You can use energy from the utility grid to supplement your system's output if it isn't providing enough electricity to run the appliances, lights, equipment, etc., that you need. It guarantees that you will always have the electricity you require.

You can always have access to power if you are connected to the grid. But some guidelines apply to you. Unless you choose a grid-tied solar system with battery backup, you won't have electricity if you have a solar system that is connected to the grid and the grid goes down.

Why Don’t Solar Panels Automatically Work in A Power Cut?

Do solar panels work in a power cut in the UK? Most homes have solar systems that are connected to the grid. You can obtain free energy during the day by using these solar panels, which convert sunlight into power. Nevertheless, since your home needs utility company electricity at night and there is no sunlight, these solar systems are inoperable during that time. 

The grids and grid-tied solar systems both shut down in the event of a weather-related power outage. The reason for this is an automated switch that makes sure no energy is sent by a solar system that is connected to the grid. Utility workers run the risk of electrocuting themselves while attempting to resolve a power outage caused by a problem with the grid or the lines. 

How to Use Solar Panels During Power Cut?

How to use solar panels during power outages in the UK? Off-grid solar systems or battery-backed solar systems are options if you want your solar panels to run during a power outage. 

Off-Grid Solar Systems

Off-grid solar systems allow you to live without relying on the utility company for energy and instead use your energy source. You may easily use solar energy as a sustainable energy source to live off-grid and avoid paying for electricity. All you need to do is purchase an off-grid solar system and locate a convenient and safe location to put up your house and begin living off-grid.

Battery Backup Systems for Solar Power

Solar power battery backup systems are the best option if you don't want to live off-grid but still want to use solar panels to acquire electricity during a power outage. You can use the BLUETTI Solar Generator Kit to convert sunlight into electricity and store it in batteries for later use. When the grid goes down, you can utilize the stored energy to run your home appliances for several hours while waiting for the blackout to end safely.

During a power outage, battery-backed solar systems provide you with a short-term energy backup. Ordinary generators, on the other hand, are expensive to operate and rely on fossil fuels to produce hazardous CO emissions that are bad for the environment and you. You can obtain free, environmentally friendly electricity with a solar generator. It is also cost-effective.

How Do You Prepare For the Next Power Outage?

How to use solar panels during power outages in the UK? No one enjoys losing power. But you can cope with them less irritatingly if you prepare ahead.

  • Make every effort to stay warm.
  • You may stay warm without using the heating in several ways. Even though being without heat would be miserable, there are short-term ways to stay warm, such as wearing thick clothing, exercising, heating any leftover water in your boiler, sitting in your car, or getting a hot beverage.

    To avoid the worst of the cold, think about stocking up on hand warmers if you frequently experience blackouts or if you just enjoy staying warm.

  • Get a standby generator.
  • If your area experiences frequent power outages, installing a diesel generator can be beneficial. These are not very environmentally friendly, but they could come in handy at times. A generator that can power your entire home is available, however, it will cost a lot to purchase and maintain. They typically call for a customized solution that should fit your unique needs.

  • Install a solar battery that can be used as backup power.
  • Your solar system may be able to provide some assistance during a blackout, depending on the type of battery you have installed. It's undoubtedly preferable to nothing at all.

    FAQ about Solar Panels during A Power Outage

    How to Use a Solar Panel Directly Without Battery?

    Although there are numerous advantages to combining solar panels with a battery, you can still do without. Setting up your solar panel can be difficult if you do not want to use a grid-connected solar system. You'll need a DC-to-DC and a DC-to-AC solar inverter, as well as the appropriate voltage for the converter to work. 

    How to Use a Solar Panel to Charge a Battery?

    Connect the BLUETTI AC300+B300+PV350 Solar Generator Kit. When sunlight strikes the solar panel, it converts the sun's energy into direct current electricity, which is then used to charge the battery in the portable power station. The recharging time is determined by the number of solar panels used.

    Will My Solar Battery Charge During A Power Outage?

    This is determined by the type of backup system you have. When a power outage is detected, some low-cost batteries will immediately discharge their stored energy. This is because the battery inverter is often smaller than the solar inverter; allowing the energy from the solar inverter to flow into the battery could overload it. If the battery inverter is larger than the solar inverter, energy can flow into the battery until it is fully charged.


    How to use solar panels during power outages in the UK? Depending on the kind of solar system being used, solar panels can play a different function during power outages in the UK. While off-grid solar systems, which are frequently fitted with battery storage, offer a dependable supply of power, on-grid solar panels do not automatically turn on during a power outage for safety concerns. Cutting-edge technologies, such as the BLUETTI AC300 + B300 + PV350 Solar Generator Kit, offer a thorough method for utilizing solar energy during blackouts, giving people and organizations a practical and sustainable substitute for conventional power sources.
