Upcoming Solar and Power Storage UK Trends: What To Expect

The power storage UK market is growing and is now adopting new trends moving forward. In 2024, the power storage industry in the United Kingdom is growing with 1,659 active UK battery storage projects and more to come. It is now moving towards new trends, including the incorporation of PV systems.

The solar capacity in the UK is growing rapidly. In 2025 alone, the UK completed 2GWp of solar power and is targeting 3.7GWp at the end of the year. This has already eclipsed 2024’s totals and showcases the UK’s dedication to solar power. This statistic falls perfectly with the initiative to make the UK a nation that runs on renewable energy.

In addition to installing PV systems, UK citizens are now starting to install battery storage systems. What was an optional choice before is now seen as a necessity, as it helps balance the grid. Paired with home PV units, it can now store surplus energy generated during the day for use during the evening, in case of emergencies.

These shifts in power generation and storage will allow consumers to save on their energy bills, have increased resilience, and make household donations that are leaning towards sustainability.

With the growing need for power storage and PV systems, EcoFlow and its products are making an impact towards sustainability and power independence. Products like the EcoFlow PowerOcean allow homeowners to store solar energy, which they can use during peak grid hours.

In 2025, the United Kingdom have already installed 2GWp of solar projects. By the end of 2025, the country aims to have 3.7 GWp of utility-scale ground-mounted solar PV systems under construction. Utility-scale ground-mounted solar-powered systems account for 70% of the country's total solar power capacity, with 1.5 GWp already installed.

Rooftop-mounted PV systems are also growing steadily at a rate of 20% year-over-year. The government is also offering incentives for homeowners to install roof-mounted solar-powered systems in their homes. With this mandate, the United Kingdom is moving towards better sustainable energy.

Homeowners will now have access to more affordable technology. They’ll also have access to better and more affordable installers for their solar power and storage units. The strong government targets will make sure that UK homeowners will get access to more sustainable power sources..

In the UK, the use of home battery storage units is growing at a fast pace. Homeowners are now starting to install power storage battery units to conserve power and have a backup source during emergencies and peak grid hours. In the United Kingdom, there are two prevalent forms of power storage, utility-scale and domestic battery storage.

Utility-scale power storage UK systems are grid-tied and store the excess energy generated by the grid. It releases this excess when grid demand is high or when sustainable sources are not generating enough. Domestic battery storage refers to the installation of storage systems in UK homes. Products like EcoFlow’s PowerOcean Three-Phase and Single-Phase units fall into this category.

A power battery storage system allows homeowners to balance supply and demand with their power grid. Using a battery storage unit and a renewable source like a Photovoltaic system will reduce curtailment as homeowners can use the stored energy during peak and high-demand hours. This will help homeowners save up on their electricity bills as well as promote renewable integration.

With the rise of roof-mounted PV systems and the Government’s mandate, home batteries are becoming more popular each year in the UK. Aside from government mandates and incentives, numerous benefits can arise from the use of domestic battery storage.

First and foremost is less reliance on your power grid. When you rely on the grid for your power, you tend to accumulate more charges, especially during peak hours. Having a backup power storage will allow you to power your home without the need for the grid and go back to using grid-connected sources during off-peak hours.

The same is true when you connect a PV system to your power storage. You can generate power through your PV and store it in your battery, like the EcoFlow PowerOcean, and use it during the evening or peak hours to save.

You can also save more by pairing your domestic battery storage with your EV charging wallbox. For example, if you are using the EcoFlow PowerPulse and PowerPulse2, you can connect them to your PowerOcean unit and use the stored energy rather than connecting to your grid.

In the UK, numerous solar resource projects are either completed or ongoing. These projects are either for general or private use. With the UK government’s mandate regarding renewable solar-powered energy sources, there is now a growing movement to build solar farms. These solar farms consist of multiple PV systems connected to generate more energy. These solar farms are connected to battery storage units that store the generated energy for use during grid peak hours and emergencies.

This is great, as most solar farms with battery storage have shared infrastructures, which leads to lower costs. They also have optimized grid connections and can adjust during periods of high demand. This also allows solar farm owners greater flexibility with how they connect to the grid.

This is relevant for homeowners who want to install a smaller-scale PV and storage system. You can store the energy generated during the day and use it to power your home during the evening or high-demand grid periods, thereby saving on charges.

With the rise of battery storage and PV systems in the UK, Ofgem, and ESO have introduced new frameworks. These solar and battery frameworks license batteries, determine tariffs, clarify regulations for co-located systems, and promote investment in electricity storage projects. There is also the issue of ED3 price control regulations, which are scheduled to take effect on April 1, 2028. DERs can now participate properly and focus on flexibility services related to power sources.

For households, it is a great way to signal that domestic batteries and small-scale solar systems can have more opportunities. Opportunities to not only feed households but also the power grid in the future. This will allow homeowners to calibrate and maintain their energy efficiency rating as well as manage feed-in tariffs.

Paired with government subsidies and incentives, it will enable the growth of wide-scale and residential battery storage and solar systems. This will also provide more flexibility for people who have installed their systems for their energy usage moving forward.

These growing trends in the UK will help alleviate high electricity prices due to the flexibility of solar-plus-storage systems. These steps will also safeguard consumers from the volatility of grid-dependent power. Due to regulations, subsidies, and incentives, it is expected that domestic battery storage adoption will increase significantly over the next 2-3 years.

Storage systems will help homeowners to power their homes if there is electric volatility and during outages, even in a limited manner. A greater number of products are compatible with battery storage units, which can facilitate better integration into smart home systems.

When integrating into a smart home, it is better to have a monitoring system that takes into account all connected devices. For a better experience, try using the EcoFlow PowerInsight and app, which can help you manage your smart home system and optimize your energy-saving technologies.

Solar power and energy storage systems are being incorporated into the mainstream in the UK. This is especially helpful for households as they can now pair their power storage battery with a PV system for a more practical, reliable, and future-facing power source. The UK government is pushing its citizens to be more sustainable and opt for more energy independence through solar systems and battery storage.

Excess electricity is stored either in large-scale energy storage facilities or through home battery storage systems. Home solar setups also often use lithium-ion batteries to store excess power for later use.

The UK adopts battery storage to balance renewable energy supply, reduce grid strain, and store excess solar or wind power for later use. This enhances energy security, reduces costs, and facilitates the transition to a low-carbon grid.

Yes, there are now regulations and incentives when installing home battery storage units. Battery storage can also be worthwhile in the UK by storing excess solar energy, thereby lowering reliance on the grid and reducing bills.
