Is It Worth Adding a Battery with Solar Panels? Exploring the Benefits for UK Homeowners

Published on:
1 September 2023

In recent years, the adoption of solar panels in the UK has witnessed a substantial increase as homeowners seek to reduce their carbon footprint and energy bills. A natural progression from this is considering adding battery storage systems to the solar panel setup. But is it truly worth the investment? This blog post delves into the benefits of combining solar panels with battery storage systems for UK homeowners.

Maximising Energy Utilisation

One of the primary advantages of incorporating battery storage alongside solar panels is the ability to maximise energy utilisation. According to the Energy Saving Trust, solar panels often generate excess energy during sunny days when energy demand is relatively low. This surplus energy can be stored in batteries for later use, such as during the evening or on cloudy days when solar panel production is lower. This self-consumption of stored energy can reduce electricity bills, as you will rely less on the grid during peak times.

Increased Energy Independence

The concept of energy independence becomes a reality by integrating battery storage systems. As stated by the Solar Trade Association (STA), combining solar panels with battery storage can provide you with a level of energy autonomy. This is particularly significant given the volatile nature of energy prices and supply uncertainties. By harnessing and storing solar energy, homeowners are less susceptible to fluctuations in energy costs and potential grid outages.

Optimising Return on Investment

Investing in solar panels is a long-term commitment, and homeowners are often reasonably concerned about the return on their investment. The addition of battery storage systems can enhance this return. According to a report by Solar Power Portal, battery storage can extend the lifespan of solar panels by allowing homeowners to manage their energy output more efficiently. This optimisation can lead to higher energy savings over the years, ultimately resulting in a better return on the initial investment.

Supporting Grid Stability

Battery storage systems can contribute to grid stability on a larger scale. The UK’s electricity grid is evolving, with a greater emphasis on renewable energy sources. The National Grid Electricity System Operator highlights that homes equipped with battery storage can participate in grid-balancing initiatives. During times of excess energy demand or supply, homeowners can discharge stored energy back into the grid, helping to stabilise the overall electricity supply.

Environmental Impact and Sustainability

A fundamental reason behind adopting solar panels and battery storage systems is to reduce environmental impact. The UK Government’s Department for Business, Energy & Industrial Strategy emphasises the importance of transitioning to cleaner energy solutions to combat climate change. By storing excess solar energy in batteries, homeowners contribute to reducing carbon emissions associated with conventional energy generation.

Factors to Consider

While the benefits are significant, it’s essential to consider a few factors before deciding to add battery storage to solar panels. Firstly, the cost of battery storage systems, including installation, must be weighed against the potential long-term energy savings. 

Additionally, the battery system size should align with your household’s energy consumption patterns. A larger battery may be necessary for homes with higher energy usage, while smaller batteries might suffice for those with lower consumption.


In conclusion, the question of whether it’s worth adding a battery with solar panels can be answered with a resounding yes, particularly for UK homeowners. Combining solar panels and battery storage systems offers benefits ranging from increased energy utilisation and independence to supporting grid stability and environmental sustainability. The positive impact of this dual solution makes it a worthy investment for those seeking to harness the power of renewable energy while enjoying financial and ecological rewards. As the UK’s energy landscape evolves, embracing solar panels with battery storage sets a promising course towards a greener and more resilient future.
