Photovoltaic energy in Europe: the future of renewable power

Solar photovoltaic energy is rapidly emerging as one of the most promising solutions for the future of global energy. Thanks to its abundance, accessibility, and continuous technological innovation, photovoltaics is expected to become the world’s leading source of energy by 2050, surpassing both gas and coal. In Europe, the adoption of solar panels is accelerating thanks to favourable policies and incentives that make this technology increasingly accessible for households, small businesses, and large companies alike. Solar power is not only an effective response to the growing demand for clean energy but also a unique opportunity to combat climate change by reducing CO₂ emissions and promoting energy self-sufficiency.

The Future of Energy: The Growing Role of Photovoltaics

Over the past decades, the global energy sector has undergone profound transformations, with a strong shift toward renewable sources. Within this context, photovoltaic energy is establishing itself as one of the most promising and accessible solutions to meet the rising demand for clean electricity. With the goal of reducing CO₂ emissions and tackling climate change, solar energy is becoming one of the primary energy sources of the future.

In Europe, and globally, solar power is reshaping the energy landscape, driven by a combination of continuous technological innovation and a sharp reduction in costs. By 2050, solar production could surpass every other energy source, including gas, coal, and even wind. This section explores why this shift is happening and why photovoltaic energy is set to become the backbone of the global energy system.

What is solar energy and how is it transforming Europe’s energy landscape?

Photovoltaic energy is the process of converting sunlight into electricity through solar panels. These panels contain photovoltaic cells that exploit the photovoltaic effect, a physical phenomenon whereby sunlight striking semiconductor materials triggers the flow of electricity. This technology is not only one of the most promising forms of renewable energy but also one of the most widely deployed worldwide.

In Europe, photovoltaics has become one of the most adopted renewable energy solutions. Its rapid growth has been supported by favourable government policies, tax incentives, and increased public awareness of the environmental benefits of solar energy. Countries such as Germany, Spain, and Italy have strongly pushed PV adoption through legislation and incentive programs that have facilitated large-scale deployment.

Why Photovoltaics Is Set to Become the Leading Energy Source by 2050

By 2050, photovoltaic energy is projected to become the world’s main source of electricity. This is not just an ambitious target but a projection grounded in concrete data and observable trends. The main drivers of this growth are continuous technological innovation and falling costs. Today, the price of installing a photovoltaic system has dropped dramatically, making it accessible to both private consumers and businesses.

Moreover, solar energy is one of the most abundant and evenly distributed resources on Earth. Every day, the Sun delivers more energy to the planet than humanity could ever consume. Unlike fossil fuels, solar energy is inexhaustible and available wherever sunlight exists.

Exponential growth of photovoltaics

Global trends and future expansion of solar energy

Global photovoltaic growth has been remarkable, especially over the last decade. According to the International Energy Agency (IEA), global PV capacity has increased by around 30% annually since 2010, driven by public policies and rapid technological progress.

Governments worldwide are recognising the potential of PV energy as a key solution for reducing emissions and transitioning to sustainable energy systems. In Europe, the shift toward a low-carbon energy model is strengthened by initiatives such as the European Green Deal, which aims to make Europe the first climate-neutral continent by 2050.

Globally, China has dominated the photovoltaic market, both in manufacturing and in large-scale installations. Europe, however, is becoming an increasingly relevant player, with significant growth recorded in countries like Germany, Italy, France and Spain.

Solar power deployment forecasts in Europe

Europe is expected to play a central role in the future of solar energy. Projections indicate that photovoltaic capacity could exceed 300 GW by 2030—double the 150 GW installed in 2020. This growth is driven by favourable policies, tax incentives, renewable energy funding, and an increasing focus on self-consumption.

Installations are no longer limited to industrial-scale systems: families and small businesses are increasingly adopting modular and scalable PV solutions, thanks to decreasing panel prices and more efficient technologies.

Why solar energy is the energy source of the future

Solar energy as an inexhaustible renewable resource

One of the main reasons photovoltaics is becoming the energy source of the future is that solar power is virtually limitless and universally available. The Sun provides hundreds of times more energy each day than what humanity consumes globally. Unlike fossil fuels, solar energy is not tied to finite reserves.

Solar energy is also evenly distributed geographically, making it accessible in almost every region of the world. This advantage sets it apart from fossil fuels, which are concentrated in limited areas.

How photovoltaics compares to other renewable technologies

Compared to wind or hydropower, photovoltaics offers key advantages:

• It is modular and scalable
  
  

• It can be integrated into urban environments
  
  

• It does not require large land areas or major infrastructure
  
  

• It can be installed on roofs, façades, and existing structures
  
  
  

As solar efficiency improves and panels perform better even under low light, PV technology becomes ever more competitive.

The Evolution of Solar Panels: Technology Driving Change

Declining Costs and Increased Accessibility

One of the main drivers of PV expansion is the massive drop in costs. Over the past decade, solar panel prices have fallen by more than 80%. This is due to:

• Technological advances
  
  

• Economies of scale
  
  

• More efficient manufacturing
  
  
  

As costs fall and efficiency improves, photovoltaic systems have become accessible to households, SMEs and large industries.

Bifacial panels, transparent modules and new sustainable solutions

Innovation is introducing next-generation technologies such as:

• Bifacial panels, which capture sunlight from both sides
  
  

• Transparent modules, allowing solar integration into windows and façades
  
  

• New materials with lower environmental impact
  
  
  

Solar windows, semi-transparent modules, and perovskite-based cells could revolutionise the sector in the coming years.

Improved Efficiency and Durability

Modern PV panels:

• convert a greater share of sunlight into electricity
  
  

• have a lifespan of 25–30 years
  
  

• degrade far more slowly than older models
  
  

• are designed to resist extreme weather
  
  
  

Solar power and self-consumption: the rise of cecentralised energy

Energy self-sufficiency through residential and commercial PV systems

Self-consumption is one of the strongest drivers of photovoltaic adoption. Solar systems allow consumers to generate electricity independently, reducing dependence on the grid and lowering energy bills.

With battery storage, self-consumption becomes even more effective, enabling the use of stored solar energy at night or during low-production hours.

The Importance of Storage Systems

Energy storage systems (batteries):

• store excess daytime energy
  
  

• allow 24-hour use of solar power
  
  

• increase energy independence
  
  

• reduce vulnerability to grid outages
  
  
  

Falling battery costs are helping accelerate their widespread adoption.

Energy Communities and the Future of Distributed Energy

Renewable energy communities allow citizens, companies and public entities to share energy produced from solar installations. This promotes:

• collaborative consumption
  
  

• decentralisation
  
  

• local energy resilience
  
  
  

Europe is encouraging energy communities through incentives and favourable legislation.
