Why Solar Batteries Make Sense for Your Home
Your solar panels will usually get the most amount light ingress around midday however this is usually when your property is using the least amount of electricity due to you being at work and the kids at school. So, what can you do to keep that surplus energy?
Installing a battery into your Solar PV system can be a game changer, instead of selling the electricity back to the grid you can use the stored energy when you are most active in your home.
If you have an electric car you can even divert that energy to charge your car or heat up your water.

Frequently Asked Questions
What is battery storage and how does it work?
Battery storage systems store excess electricity generated from solar panels or the grid for later use. Typically they use rechargeable lithium-ion batteries to store and discharge energy as needed.
What are the benefits of battery storage?
There are many key benefits for battery storage here is a short list including storing excess solar energy for use at night or during outages Reducing reliance on the grid and lowering electricity bills, Providing backup power during outages (systems like the Tesla power wall can stop those annoying power outages if you live in an area prone to power cuts), Even if you don’t have solar panels, you can charge your battery on a late-night tariff (where electricity is cheaper) and discharge it during the day when electricity costs are higher.
Are we qualified to install these?
Yes, all our engineers have undertaken solar and battery storage training to gain their qualifications. OJF are also part of RECC (Renewables Energy Consumer Code) and are MCS (Microgeneration Certification Scheme) certified.
How long do battery storage systems last?
Most lithium-ion battery systems are warranted for 10 years and can last 15-20 years with proper maintenance. Battery capacity gradually degrades over time.
What size battery system do I need?
The size depends on you and your family’s energy usage, solar system size (if applicable), and goals. A typical home system ranges from 5-20 kWh of capacity but can go all the way up to 80kWh if needed in a domestic property
Can battery storage be added to an existing solar system?
Yes, in most cases battery storage can be retrofitted to existing solar panel systems. If your inverter installed is a ‘String’ inverter we will need to change the inverter to a ‘Hybrid’ version to allow the installation of a battery
How much maintenance is required?
Think of the battery as an iPhone, it needs minimal maintenance. Regular monitoring and occasional firmware updates are typically all that’s needed – Simple!
Are there safety concerns with battery storage?
Modern battery systems have multiple safety features and must comply with strict UK electrical and fire codes. Proper installation by qualified professionals is important.
Can battery storage power my whole house during an outage?
It depends on the system size and your energy usage within your property. Many systems can power essential loads during an outage. For example, the leading battery for power outages is the Tesla Power Wall, these have a discharge rate of 5kW (per power wall).
