SOLAR Battery Storage FAQ’s

Knowledge is Power

Solar battery storage is an innovative technology that allows for the efficient storage of energy generated by solar panels. It works by converting the direct current (DC) electricity produced by solar panels into alternating current (AC) electricity, which can then be used to power homes or businesses. The process begins when solar panels absorb sunlight and convert it into DC electricity. This electricity is then directed to an inverter, which transforms it into AC electricity, suitable for everyday use.

However, not all the energy produced is immediately consumed. This is where solar battery storage comes in. Excess energy, instead of being sent back to the grid, is stored in these batteries. Solar batteries are designed to store this surplus energy, and because of this, they play a crucial role in ensuring a consistent power supply, even when the sun isn’t shining. For instance, during the night or on cloudy days, the stored energy can be used, ensuring that solar power systems are not solely dependent on real-time sunlight.

And there’s more to solar battery storage than just providing backup power. It also enables homes and businesses to become less reliant on the traditional power grid, potentially leading to reduced energy bills. But the benefits extend beyond financial savings. Because solar battery storage systems allow for the more efficient use of renewable energy, they also contribute to the reduction of carbon emissions, supporting environmental sustainability.

So, in summary, solar battery storage works by storing excess energy produced by solar panels, ensuring a reliable power supply regardless of sunlight availability, and contributes to both financial savings and environmental protection.


The Sun, an immense powerhouse in the sky, showers our planet Earth with a staggering amount of energy. In just one hour, it emits more energy than the entire global population uses over the span of an entire year. This fact opens up a world of possibilities for harnessing solar power. Imagine if every single rooftop in the United Kingdom was equipped with solar panels, each connected to efficient battery storage systems. This scenario could revolutionize our energy landscape. Such a setup would potentially generate enough electricity to meet every power need across the country, impacting every aspect of our daily lives. Recognizing the importance of this knowledge and its potential to empower individuals, we have embarked on an ambitious project to create a comprehensive database. This resource is designed to provide all the essential information one might need to make informed, forward-thinking decisions about their energy future, exploring the benefits and practicalities of embracing solar energy and other renewable sources.

Solar battery storage refers to the process and technology involved in capturing and retaining the energy produced by solar panels. Solar panels, typically installed on rooftops or other strategic locations, absorb sunlight and convert it into electricity. This electricity, however, is often generated at times when it is not immediately needed, such as during the day when solar irradiance is at its peak.

To maximize the utility of this solar-generated electricity, it is stored in specially designed batteries. These solar batteries are engineered to hold large amounts of electricity for later use. When the sun is not shining, such as during the night or on cloudy days, the stored energy in these batteries can be tapped into to provide a continuous and reliable power supply. This system ensures that the fluctuating availability of sunlight does not disrupt the steady provision of electricity.

Moreover, solar battery storage enables users to become less reliant on the traditional power grid, offering a more sustainable and eco-friendly way to meet energy needs. It can also provide significant cost savings over time, as the stored solar energy can reduce or even eliminate the need for electricity from conventional, often more expensive, sources.

The question of needing batteries when you have solar panels arises because solar energy systems primarily generate power during daylight hours. Over the course of a 24-hour period, there are significant times, specifically during the night, when these systems are not producing electricity because of the absence of sunlight. If your solar panel system generates more electricity than you use during the day, this excess energy is typically exported back to the grid, rather than being utilized directly in your home.

Introducing a battery storage system to your solar setup can change this dynamic significantly. Batteries have the capability to store most, if not all, of the surplus energy generated by your solar panels during the day. This stored energy can then be used during the night-time hours, when your solar panels are not producing power. In essence, battery storage allows you to capture the excess energy that would otherwise be sent back to the grid and use it during times when your solar panels are inactive, providing a more consistent and self-reliant source of electricity regardless of the time of day.
