Solar Manufacturing Investment to Triple by 2035, Reshaping European Supply Chains

This forecast of tripling manufacturing CAPEX is the clearest signal yet that the global solar industry is entering its next major phase: massive vertical integration and supply chain localization. For European installers, this isn't just a distant manufacturing story—it directly impacts project costs, equipment availability, and competitive positioning over the next decade.

Why This Matters for European Solar Businesses

The projected $43.8 billion annual investment by 2035 will fundamentally reshape equipment markets. We're moving beyond the current cycle dominated by Chinese oversupply and price volatility. This capital influx will fund next-generation technologies (like TOPCon and perovskite-tandem lines), create new regional manufacturing hubs (especially in the US and India due to IRA and PLI schemes), and potentially ease the bottleneck in critical components like inverters and mounting systems that have plagued European projects.

Market Implications: Prepare for a Bifurcated Supply Chain

European installers should anticipate a two-track market emerging by the late 2020s. On one side, ultra-low-cost Asian modules will continue for utility-scale projects where price dominates. On the other, premium-priced 'Made in Europe' products (supported by the Net-Zero Industry Act and potential CBAM adjustments) will cater to residential and commercial segments where sustainability credentials and supply chain transparency command a premium. The smartest installers are already building supplier relationships with both tracks.

What to Watch For

• Technology Shifts: This capital will accelerate the transition from PERC to TOPCon and eventually perovskite-tandem cells. Installers need to understand the performance and degradation profiles of these new technologies.
• Regional Content Requirements: National incentives across Europe will increasingly tie subsidies to local manufacturing content. Track policy developments in Germany, Spain, and France closely.
• Equipment Innovation: Watch for breakthroughs in balance-of-system components—smarter inverters, lightweight mounting, and integrated storage solutions that will emerge from this R&D investment wave.

The message is clear: The solar industry is graduating from a 'garage startup' phase to becoming a capital-intensive industrial powerhouse. Installers who understand this transition will secure better margins and more resilient supply chains.
