European countries are well into the era of annual TERRAWATTHOUR generation from solar PV, and the trend continues.
Here’s some outtakes from this years Photovoltaics Report (2025) from Fraunhofer ISE, indicating the global state of solar photovoltaics (PV), some market trends, latest efficiency records, life-cycle metrics, and cost developments.
PV Market Growth & Installed Capacity
PV continues its rapid expansion globally. From 2014 to 2024, the compound annual growth rate (CAGR) of PV installations hovered around 27 %. In Germany, renewable energy accounted for 188.4 GW of the country’s 263.9 GW net installed electric generation capacity by early 2025, representing 71.4 % of the total.
Every six months Germany is installing the equivalent 8 GW that represents Ireland’s ENTIRE SOLAR AMBITION, ie 8 GW by 2030. In 2024 alone photovoltaics in Germany generated 74 TWh, avoiding approximately 51 million tonnes of CO₂-equivalent emissions.
Global PV Production
Global PV module production reached around 703 GWp in 2024, dominated by monocrystalline silicon at 687 GWp, with thin-film technologies contributing the remainder.
Solar PV Efficiency
- Commercial crystalline-Si (c-Si) wafer-based modules achieved a weighted average efficiency of 22.0 % in Q4 2024—up from 21.6 % in Q4 2023; the lowest and highest performers in the top-10 shipment group ranged between 18.8 % and 23.8 %.
- Market momentum is shifting from p-type PERC technology toward more efficient n-type TopCon and heterojunction (HJT) modules.
Factors in Recycling Solar Panels
- The energy payback time (EPBT) for rooftop monocrystalline systems produced in Europe is shorter than those produced in China, driven by higher grid efficiency — even though irradiation influences EPBT as well.
- PV module mass comprises mainly glass, aluminum frames, and other materials. While up to 100 % material recycling is technically feasible, in practice, only glass, frame, and junction box are typically recycled today. The WEEE directive stipulates at least 80% of PV modules mass must be recycled.
- Recommendations include reducing material intensity (e.g., thinner glass), substituting silver with less scarce elements like copper or aluminum, minimizing use of hazardous substances, and improving design for recyclability.
LCOE for Solar PV (to 2025)
- Globally, the weighted average levelized cost of electricity (LCoE) for large PV systems in 2023 stood at 0.036 €/kWh, down significantly over the past decade; the global total installed cost averaged 617 €/kWp, also showing a consistent downward trend.
- Every time PV cumulative module production doubled historically, module prices dropped by approximately 25.7 %, reflecting a strong learning curve effect.
Summary: The Fraunhofer ISE Photovoltaics Report (May 29, 2025) delivers a clear picture: PV continues robust global growth, with efficiency and sustainability improving steadily. Costs are falling, policy frameworks are ambitious — especially in Germany — and evolving technologies (TopCon, HJT) are reshaping the market. The shift toward healthier life-cycle practices, increased recyclability, and efficiency gains underpins PV’s central role in the transition to clean energy.
