The solar power industry is poised for significant advancements in 2025, driven by technological innovations, policy shifts, and increasing global demand for renewable energy. Here are ten key trends and statistics to watch out for:

One: Technological innovations in solar panels will increase in 2025

Advancements in solar panel technology are enhancing efficiency and reducing costs. Notably, Qcells has achieved a world record efficiency of 28.6% for a large-area silicon solar cell topped with perovskite, potentially reducing the space required for installations.

Two: Solar energy storage capacity will continue to growth rapidly

The integration of energy storage systems is addressing the intermittency of solar power, improving grid stability, and enabling energy availability during peak demand or nighttime. This trend is particularly significant in the UK, where it is predicted that battery storage capacity will increase from the current level of 2.1GW to around 24GW by 2030.

Three: Community and decentralised solar projects will expand

Community solar projects are expanding access to solar energy for those unable to install individual rooftop panels. In the UK, large-scale solar farms are becoming increasingly common, with over 1,336 operational sites and more planned, enhancing energy accessibility and contributing to decarbonization objectives.

Four: In the UK, there will be significant investment in solar infrastructure

Major investments are propelling the solar industry forward. In the UK, the government’s clean energy plan will require investments in excess of £40 billion between 2025 and 2030 to drive renewable output, upskill workers and decarbonise the economy.

Five: The corporates adoption of solar energy will continue

Businesses are increasingly adopting solar energy to meet sustainability goals and reduce operational costs. In the UK, companies like Marks & Spencer and Tesco entering into long-term solar power infrastructure projects, reflecting a broader corporate shift towards renewable energy sources.

Six: Policy support and government targets will drive the solar industry in 2025

The UK government has laid out ambitious targets for solar energy capacity expansion as part of its plans and commitment to decarbonising the electricity system by 2030. The government’s Clean Power 2030 Action Plan—unveiled in December 2024—aims to increase solar capacity to approximately 45–47 gigawatts (GW) by 2030.

Seven: There will be further advances in solar panel recycling

As solar installations age, recycling technologies are developing to manage end-of-life panels, recovering valuable materials, and reducing environmental impact. In 2024, the global solar panel recycling market was worth US$ 1.87 billion in 2024 and is expected to exceed US$ 118.54 billion by 2037, expanding at a compound annual growth rate of over 37.6% during the period 2025 to 2037.

Eight: Artificial intelligence will play a key role in both solar energy management and usage

Artificial intelligence (AI) will both help to optimise solar energy production through improvements in supply-chain efficiency, but also drive up the demand for renewable energy via ever-expanding energy-hungry data centres.

Nine: Floating solar farms will continue their expansion

Floating solar farms, installed on bodies of water, are emerging as a solution to land constraints, offering efficient energy production without occupying valuable land resources. This innovative approach is gaining attention globally and could influence future solar projects. In fact, annual floating solar installations are expected to exceed 6 gigawatts (GW) by 2031. Moreover, the value of the global floating solar panel market was around US$ 35.6 million in 2022 and is projected to exceed US$ 180 billion by 2030.

Ten: We will see more integration of solar energy technology with Electric Vehicle (EV) Infrastructure

The convergence of solar power and EV charging infrastructure is set to play a pivotal role in the UK’s renewable energy landscape. Innovations such as solar carports are being developed to provide efficient charging solutions for electric vehicles, utilising solar panels to generate clean energy on-site. This integration supports the growing adoption of EVs and contributes to the decarbonisation of the transport sector.

Solar Power trends and statistics in 2025 will be shaped by a multitude of factors, helping to bring renewable energy to more households, businesses and schools
