As the colder months arrive, power cuts can become an unwelcome disruption for homes and businesses. Strong winds, heavy rain and faults on the electricity network can all leave properties without power, sometimes with very little warning.
While power cuts aren’t always preventable, there are steps you can take to prepare your property, reduce disruption and become less reliant on the National Grid.
For homeowners and businesses looking for greater energy independence, solar panels paired with battery storage can offer a practical, long-term solution.
At SJM Renewables, we help domestic and commercial clients across Worthing, West Sussex and the surrounding areas make better use of renewable energy through bespoke Solar PV and battery storage installations.
Why Do Power Cuts Happen?
Power cuts can occur for several reasons, particularly during autumn and winter when adverse weather conditions can affect the electricity network.
Common causes include:
- Strong winds damaging overhead power lines
- Heavy rain, flooding or storm-related damage
- Faults on the local electricity network
- Planned maintenance by electricity network operators
- Increased demand on electrical infrastructure
- Faults within a property’s electrical installation
Although many of these issues are outside your control, being prepared can help minimise the impact on your home or business.
How to Prepare Your Property for a Power Cut
A little preparation can make an unexpected power cut much easier to manage.
Whether you’re responsible for a family home or commercial premises, there are several practical steps worth taking.
Keep Essential Supplies Accessible
Make sure you have torches, spare batteries and fully charged power banks available.
Battery-powered lighting is generally a safer alternative to candles, particularly in homes with children or pets.
It’s also worth keeping important contact numbers accessible, including the free UK power cut helpline, 105.
Protect Essential Equipment
Power interruptions can affect everything from household appliances and internet connections to business equipment and security systems.
Consider which electrical devices are essential to your daily activities and whether they require additional protection.
For businesses, this might include computers, communications equipment, security systems or other critical operations.
Consider Backup Power Solutions
For properties where maintaining an electricity supply is particularly important, investing in suitable backup power can provide additional reassurance.
Solar PV systems paired with battery storage can offer backup electricity during a power cut, provided the installation has been specifically designed with this functionality.
Not all battery systems automatically provide power during an outage, which is why professional system design is essential.
How Can Solar Panels and Battery Storage Help During a Power Cut?
Solar panels and battery storage work together to help you generate, store and use more of your own renewable electricity.
During daylight hours, your Solar PV system generates electricity that can be used throughout your property.
When your solar panels produce more electricity than you’re using, the excess can be stored in a battery rather than exported to the National Grid.
This stored electricity can then be used later, such as during the evening or when solar generation is lower.
However, one of the additional benefits of a correctly designed battery storage system is the potential to provide backup electricity during a power cut.
Can Solar Panels Work During a Power Cut?
One of the most common misconceptions about solar panels is that they will continue powering your property whenever the National Grid goes down.
In reality, most standard grid-connected Solar PV systems automatically shut down during a power cut.
This is an important safety feature designed to prevent electricity from being exported into the network while engineers may be working to restore the supply.
However, when solar panels are paired with a compatible battery storage system and the appropriate backup equipment, selected parts of your property can continue receiving electricity during an outage.
Depending on the system design, solar panels may also be able to continue generating electricity and recharge your battery while the grid is unavailable.
What Are the Benefits of Solar Battery Storage?
Battery storage offers advantages beyond providing potential backup power.
For both domestic and commercial properties, it can help improve energy efficiency and make better use of the electricity generated by solar panels.
Greater Energy Independence
By storing excess solar electricity, you can reduce the amount of energy you need to purchase from the National Grid.
This gives you greater control over how and when you use electricity throughout your property.
Reduced Energy Bills
Using stored solar electricity during the evening or periods of higher demand can help reduce your reliance on purchased electricity.
The savings available will depend on your energy consumption, electricity tariff, system size and how much solar energy you generate.
Backup Power During Outages
With the correct equipment and installation, battery storage can provide electricity to selected essential circuits when the grid supply is interrupted.
Depending on the system’s capacity and configuration, this could include lighting, refrigeration, internet equipment or other essential appliances.
The amount of backup power available and how long it lasts will depend on the battery’s charge level, capacity and the electrical demand placed on it.
Make Better Use of Renewable Energy
Rather than exporting all your unused solar electricity, battery storage allows you to retain more of that energy for your own use.
This can increase the proportion of your electricity consumption met by your Solar PV system and support your wider sustainability goals.
Future-Proof Your Property
As renewable energy technology continues to develop, combining Solar PV with battery storage can help prepare your home or business for changing energy requirements.
Whether you’re planning to install an EV charging point, upgrade your heating system or simply reduce your reliance on grid electricity, battery storage can form part of a longer-term energy strategy.
Can Battery Storage Be Added to Existing Solar Panels?
Yes. In many cases, battery storage can be added to an existing Solar PV installation.
You don’t necessarily need to replace your current solar panels to benefit from a battery system.
However, compatibility depends on your existing inverter, electrical installation and the type of battery storage system being considered.
If backup power is a priority, it’s particularly important to establish whether your existing equipment can support this functionality.
At SJM Renewables, we assess your current system, energy usage and future requirements before recommending a suitable battery storage solution.
What About Commercial Properties?
For businesses, even a relatively short power cut can cause significant disruption.
Loss of lighting, internet connectivity, security systems or essential equipment can affect productivity and business continuity.
Commercial solar battery storage can help businesses make better use of the renewable electricity they generate while reducing reliance on the National Grid.
Where backup functionality is required, a properly designed system may also support selected essential operations during an outage.
However, not every commercial battery installation is designed to provide uninterrupted power. Businesses with critical equipment may also require a dedicated uninterruptible power supply (UPS) or another specialist backup solution.
Understanding your operational requirements is essential when choosing the right system.
