How are Solar Panel Storage Batteries useful in a power outage?

Solar power batteries have become an increasingly popular solution for providing backup power during power cuts.

With more and more homes relying on renewable energy sources, having a backup power source is important to ensure that essential appliances and lights stay on during power cuts or outages. But just how long can solar power batteries provide power during a power cut?

In this blog, we’ll explore the factors that determine how long solar power batteries can provide power and help you understand what you need to know to choose the right solar power battery for your home.

We’ll cover topics such as battery capacity, energy usage, solar panel output, and more to give you a comprehensive understanding of solar panel storage batteries

Power cut solar batteries

Solar panel storage batteries – how do they work?

Solar storage batteries work by storing excess energy generated by solar panels during the day and then releasing it as needed, such as during a power cut.

Solar storage batteries consist of a series of interconnected batteries that store energy as direct current (DC) electricity. The energy generated by the solar panels is converted into DC electricity and then stored in the batteries.

When the grid goes down and there is a power cut, the stored energy can be converted back into alternating current (AC) electricity, which is the type of electricity used in homes, and used to power essential home appliances.

How long can solar panel storage batteries power appliances?

The length of time that solar power batteries can power essential items in a home during a power cut depends on several factors.

Battery Capacity

The first is battery capacity. Battery capacity is a measure of the amount of energy that a battery can store and release. When it comes to solar power batteries, the capacity is expressed in kilowatt-hours (kWh). The larger the battery capacity, the more energy it can store and provide during a power cut.

When choosing a solar power battery, it’s important to consider the capacity that you’ll need based on your energy usage during a power cut. For example, if you want to be able to power a few lights, a small refrigerator, and a television for several hours during a power cut, a battery with a capacity of 10-15 kWh should be sufficient.

However, if you want to be able to run more energy-intensive appliances such as air conditioners or electric stoves, you’ll need a larger capacity battery.

Solar Panel Output

The output of a solar panel is directly related to the performance of a solar panel battery.

The size and wattage of a solar panel determines the amount of energy that the panel can generate, while the capacity of a solar storage battery determines the amount of energy that can be stored.

A larger solar storage battery will theoretically store a higher amount of energy, meaning that it can be used for longer depending on the next condition…

Energy Usage

The amount of energy that you use during a power cut has a significant impact on the length of time that a solar power battery can provide power.

If you use a lot of energy-intensive appliances, such as air conditioning or electric heating, the battery will discharge more quickly, and you’ll need to replace it sooner.

How do I reduce energy usage so my solar battery lasts longer?

Fortunately, we are lucky that most power outages don’t last very long in the UK, although the average in 2021 was between 30 and 50 minutes in total which can cause a high inconvenience if this is even a monthly occurrence.

There are several things that you can use to reduce your energy usage during a power cut and extend the life of your solar power battery when there is a power outage.

  • Using energy-efficient appliances, such as LED lights and low-power electronic devices
  • Turning off appliances and lights that you’re not using
  • Unplugging electronic devices when they’re not in use
  • Keeping the temperature in your home moderate, rather than using air conditioning or electric heating
