Get more from your solar system with smart battery storage.

Solar panels are a fantastic way to generate your own electricity, but without a battery, much of that clean energy could go to waste. A solar battery stores the excess power your panels produce during the day, allowing you to use it later when the sun isn’t shining.

At Solar First, we help customers across Rutland, Leicestershire, Northamptonshire, Lincolnshire, and Cambridgeshire make the most of their solar energy. Whether you already have panels installed or you’re starting fresh, adding a battery means greater energy independence, better savings, and more control over how and when you use electricity.

We’ll help you understand your options, assess your usage, and recommend the best battery setup for your home or small business, all with honest advice, certified products, and no sales pressure.

What is a Solar Battery?

A solar battery is a rechargeable unit that stores surplus energy generated by your solar panels. Instead of sending that energy back to the grid, you keep it and use it later when you need it most, like in the evenings, overnight, or on low-sunlight days.

Battery storage systems are usually compact and wall-mounted, with smart features like mobile monitoring, time-of-use scheduling, and integration with EV chargers or home heating systems. Many modern batteries also support “grid balancing,” allowing you to buy and store electricity when it’s cheap and sell it back at peak times if your tariff allows.

Some key features include:

  • Lithium-ion technology for long life and high efficiency
  • Modular storage sizes to suit different properties
  • Compatibility with most solar panel systems
  • App-based usage tracking and smart charging settings

 

With a battery, your solar system becomes more than a daytime energy generator — it becomes a 24/7 energy solution.

Benefits of Solar Battery Storage

Adding battery storage to your solar system unlocks a range of powerful benefits:

  • Lower Energy Bills: Use your own power in the evening instead of paying peak electricity rates.
  • Energy Independence: Reduce reliance on the grid and protect yourself from price rises or supply issues.
  • Increased Self-Consumption: Make the most of the energy you generate, especially if you’re out during the day.
  • Smart Export Guarantee (SEG): Still export any excess energy you don’t use and get paid for it under SEG schemes.
  • Backup During Outages (with certain systems): Some batteries can provide emergency power if the grid goes down.
  • Future-Proof Flexibility: Works alongside EV chargers, air source heat pumps, and time-of-use tariffs for a smarter home.

 

For customers on variable-rate tariffs like Octopus Agile or those with electric vehicles, a battery system can dramatically enhance overall energy efficiency.

Is a Battery Right for You?

Solar batteries aren’t one-size-fits-all. They’re best suited to homes and businesses with:

  • High energy use in the evening or early morning
  • An existing solar PV system with excess generation
  • Interest in reducing grid dependence or going off-grid
  • EV chargers or time-of-use energy tariffs
  • A desire for greater control over bills and usage

 

We’ll help you assess your electricity usage patterns and design a solution that offers real savings, not just a shiny gadget. We’ll also advise on compatibility, future-proofing, and how to integrate your battery with other renewable technologies.
