Solar power storage batteries

What is a Solar Battery?

A solar battery is a storage unit that allows you to store the excess electricity generated by your solar panels. This stored energy can be utilised when your solar panels are not generating sufficient power, such as in the evening or on cloudy days, and will ensure you still have energy during power outages.

How Do Solar Batteries Work?

When your solar panels generate excess electricity, it is directed to the battery for storage. The stored energy can be used when your energy consumption exceeds the solar panel’s current output. This ensures a continuous and reliable power supply for your home, reducing reliance on the grid and maximising energy independence.

There are two types of systems available: AC and DC coupled. Solar batteries store energy in DC form, but to be utilised in your home, it must be converted to AC. 

With an AC-coupled system, energy is generated and converted into AC by your inverter; if it is not used, it is then transformed by a second inverter back into DC in order for your battery to store it or to be fed back to the grid. Whereas a DC-coupled system flows the energy into a charge controller, which feeds it into the battery, it is only converted to AC when needed. DC-coupled systems are more efficient as the energy is only converted once. However, AC-coupled  systems are generally less complex and, thus, cheaper to install.

Is a Solar Battery Storage System Right for My Home?

Installing solar power battery storage in your home in Essex and the south east offers several benefits. Having battery storage ensures that you have access to power around the clock, even during nighttime or periods of low sunlight, providing greater energy reliability and independence. Battery storage systems also provide backup power during grid outages, ensuring that essential appliances continue running.

Which Solar Battery Types Are There?

Several types of solar batteries are available, each with pros and cons. Here are the most common types:

Lithium-ion solar batteries

These batteries are known for their high energy density and longer lifespan. They are lightweight and commonly used in solar systems due to their efficiency and reliability.

Lead-acid solar batteries

This is a more traditional and cost-effective option. Lead-acid batteries are widely used in off-grid solar systems but have a shorter lifespan than lithium-ion batteries.

Lithium iron phosphate batteries

These batteries are gaining popularity in solar applications due to their enhanced safety, stability, and long cycle life. They provide reliable performance and are generally considered a safer alternative to other lithium-ion batteries.

Nickel-cadmium batteries

While less commonly used in solar applications, nickel-cadmium batteries offer high energy density and excellent durability. They are known for their ability to withstand extreme temperatures and heavy usage.

Flow batteries

Flow batteries, also known as redox flow batteries, have the unique ability to store large amounts of energy. They offer a longer lifespan and are ideal for applications that require continuous and long-duration energy supply, making them suitable for solar systems that require sustained power output.

Each battery type has its advantages and considerations, and the choice depends on specific requirements, such as energy storage capacity, lifespan, safety, cost, and application.

Which brands of batteries are available?

At Prime Time Solar, we offer batteries from SolaX and GivEnergy. These brands are well known for their quality and reliability, and we have a wide range of battery options available to suit your needs. SolaX provides various solar battery options, including the X-Hybrid and Triple Power series.

What Are the Pros and Cons of Solar Batteries?


  • Energy Independence: Solar batteries allow you to store excess energy and use it when needed, increasing your self-consumption and reducing your reliance on the grid.
  • Cost Savings: Using stored energy during peak times can reduce your electricity bills and take advantage of lower energy rates.
  • Backup Power: During a power outage, solar batteries provide a reliable source of electricity, ensuring that your essential appliances continue to operate.


  • Cost: Solar batteries are an additional investment, which may increase the overall cost of your solar energy system.
  • Limited Capacity: The storage capacity of solar batteries is limited, and you’ll need to choose an appropriately sized battery based on your energy needs.
  • Maintenance: Depending on the battery type, some maintenance may be required to ensure optimal performance and lifespan.

How Much Does Home Battery Storage Cost?

The cost of home battery storage can vary based on various factors, such as the battery’s capacity, the type of battery, and installation requirements. We can provide customised quotes based on your specific needs and requirements.

Frequently Asked Questions (FAQs)

Can I install a solar battery storage system myself?

No, it is recommended to have a professional solar installer handle the installation of a solar battery storage system. They have the expertise and knowledge to install the system safely and correctly, ensuring optimal performance and safety.

How long do solar batteries last?

The lifespan of solar batteries can vary depending on the type and manufacturer. On average, lithium-ion batteries used in residential solar systems can last anywhere from 10 to 20 years. It’s important to check the warranty information provided by the manufacturer for specific details.

Will a solar battery system reduce my electricity bills?

Yes, by storing excess energy generated by your solar panels, you can utilise stored energy during peak times or when your solar panels are not producing enough power, resulting in lower reliance on the grid and potential cost savings.

What maintenance is needed for solar batteries?

Solar batteries generally require minimal maintenance. However, having them regularly inspected by a professional is recommended to ensure optimal performance. Additionally, monitoring the battery’s state of charge and scheduling regular cleanings of the solar panels can help maintain efficiency.
