Top 12 Solar Farm Investment Destinations

Top 12 Solar Farm Investment Destinations in Europe & Eurasia: Expert EPC & Advisory Analysis 2025

A comprehensive investment guide for institutional investors seeking profitable photovoltaic opportunities with professional EPC and advisory services

The European and Eurasian solar investment landscape has fundamentally transformed, creating exceptional opportunities for institutional investors seeking both superior returns and environmental impact. According to Ember’s latest energy analysis, solar became the EU’s largest single source of electricity in June 2025 for the first time ever, achieving a record 22.1% share. This milestone reflects the sector’s maturation and the increasing sophistication of solar farm development across diverse geographic markets.

The financial fundamentals driving this transformation are compelling. IRENA’s Renewable Power Generation Costs 2023 report shows global weighted average LCOE of utility-scale PV plants has fallen to US$0.044/kWh, representing a 12% year-on-year decline and an unprecedented 90% reduction since 2010. This cost competitiveness, combined with increasingly sophisticated policy frameworks and advanced EPC capabilities, has established utility-scale solar photovoltaics as the premier infrastructure investment opportunity of the decade.

Aurora Energy Research’s European Solar Markets Attractiveness Report identifies Germany, Spain, and Italy as the three most attractive solar markets for investors in Europe, with these countries expected to host 58% of the continent’s installed PV capacity by 2030 and attract 83% of the €148 billion investment required to meet projected growth. However, our comprehensive analysis reveals that exceptional investment opportunities extend far beyond these established markets, encompassing emerging economies with superior IRR profiles and strategic advantages for experienced solar farm developers.

Spain: The Mediterranean Investment Champion

Spain stands as the undisputed leader among European solar investment destinations, where exceptional natural resources combine with mature regulatory frameworks to create an environment where investors achieve the highest returns on unsubsidized utility-scale developments. Spain’s Ministry for Ecological Transition reports solar irradiance levels exceeding 1,800 kWh/m² in optimal locations, providing the fundamental resource foundation that drives project economics superior to any other European market.

The financial performance metrics demonstrate Spain’s investment superiority. Spanish utility-scale solar projects consistently deliver internal rates of return between 12% and 17% without requiring significant government subsidies, according to Aurora Energy Research’s market analysis.

In Málaga, ETIP PV’s LCOE calculations show utility-scale PV LCOE at €24/MWh in 2024, declining to €19/MWh by 2030 and €13/MWh by 2050. These economics are supported by Spain’s increasingly sophisticated Power Purchase Agreement market, with PV Tech reporting that Spanish companies lead European adoption of long-term electricity contracts providing revenue certainty for project developers.

Recent market activity demonstrates the scale of opportunity available to experienced EPC contractors and institutional investors.
