As we enter the final quarter of this year, we’re naturally looking ahead to the trends we might see across the solar energy industry in 2025.
Advancements in photovoltaic technology, innovations throughout the renewable energy sector as a whole and a drive towards sustainability means the next 12 months are shaping up to be revolutionary for the solar energy industry.
Below we explore the top trends we’re expecting to see going forward.
Five future trends across solar energy in 2025
With 2025 around the corner, here’s the top five trends we expect to see taking place:
1. Advancements in solar panel technology
An ever-present trend across the industry is the advancement of solar panels, their efficiency and their various applications.
Over the last five years, we’ve seen huge strides in the development of the panels themselves, with new materials and improved designs enabling solar panels to convert sunlight into energy more effectively. Next year is set to be no different.
As the technology becomes more effective and accessible, it also becomes more practical and cost-effective for businesses. Only this year, research by the University of Surrey resulted in a manufacturing breakthrough of ‘next-generation solar cells’ which are both cheaper and lighter than traditional alternatives.
This vastly increases the number of potential applications and creates a more competitive market for solar energy professionals seeking top roles.
2. Improvements in energy storage capacity
A key part of ensuring solar energy’s viability is by improving energy storage capabilities. While technological advancements improve our ability to capture energy, it also supports advancements in the storage of this energy.
New solutions such as lithium-ion and solid state batteries are crucial for building a consistent energy supply, maintaining a reliable stream of energy even during non-sunny days.
Likewise, we’re seeing the integration of smart technology into the wider production process which is streamlining the entire system. Energy professionals can now use AI tools to facilitate real-time monitoring, optimisation and maintenance, vastly improving the efficiency of invested resources.

3. Adoption by developing nations
As the solar energy industry becomes more accessible, expect to see developing countries invest in their infrastructure.
With the cost of solar energy and PV infrastructure falling, it’s becomes much more viable for countries to adopt – providing sustainability and cost-effectiveness.
This not only provides power for millions of households but allows these countries to start developing energy independence, driving economic growth and indirectly impacting the quality of life throughout the country.
4. Floating solar installations
A key trend in 2024 was the commissioning of floating solar farms across key areas. Over the last year, huge projects have been commissioned throughout Europe, Asia and various parts of the Americas – signifying a shift towards a new method of energy production.
It’s expected that this trend will continue in 2025, particularly in areas that house significant bodies of water. By making use of all available resources, these ‘hybrid’ systems leverage floating solar platforms alongside wind and hydro infrastructure, creating an effective and completely renewable energy source.
5. Renewables take the lead
According to expert forecasts, 2025 could be the year that renewable energy finally becomes the largest source of electricity generation.
As government initiatives and guidelines have pushed for true sustainable energy production, 2025 could be the year we see a major milestone achieved.
If we look ahead even further, these same forecasts suggest that by 2028, renewable energy will account for 42% of electricity generation. If we break this number down again, the share of wind and solar PV doubles to 25% – highlighting the sector’s potential going forward.
