Europe's installer market shifts to home batteries as price pressure rises

New research from Deventer software company OpusFlow says Europe’s renewable-energy installation market is entering a more competitive phase, with home batteries emerging as the fastest-growing segment in several countries. Installers are facing tighter margins, longer sales cycles and policy uncertainty as they move from selling solar panels to delivering broader energy-management solutions.

Why it matters: - The European installation market is moving from rapid expansion to margin pressure and tougher competition. - Home batteries are becoming the clearest growth engine for installers in several key markets. - The shift changes what wins business: efficiency, customer experience and complete energy solutions now matter more than technical expertise alone.

What happened: - OpusFlow, a Deventer-based ERP platform for the installation sector, surveyed installation companies in the Netherlands, Belgium, Germany and Spain. - The research says the market for sustainable-energy installations has entered a new phase. - Solar panels and heat pumps are under pressure, while battery energy storage is emerging as the strongest growth market. - OpusFlow said the market is not shrinking, but becoming more mature.

The details: - About half of installers expect price pressure to continue through 2026. - Most respondents identified intense competition and price pressure as their biggest operational challenge. - About half of the companies see uncertainty around government subsidies and policy as a major risk for the next year. - Buyers are requesting more quotes, asking more detailed questions and taking longer to decide. - Turning interest into profitable projects has become a top challenge for installation companies. - In the Netherlands, Belgium and Spain, installers named energy storage as the fastest-growing segment in their business. - In those markets, battery demand ranked ahead of solar, heat pumps and EV chargers. - Germany was the exception, where demand for standard solar installations still leads. - The shift toward batteries reflects demand for control over energy costs and for energy management, not just power generation. - Larger project values and longer customer relationships are becoming more common as installers move into energy optimization. - The trend aligns with recent market data from the International Energy Agency, which forecast a rapid battery rollout to help meet Europe’s demand for flexible energy.

Between the lines: - The easy-growth phase for installers appears to be over. - Companies that can move faster, communicate better and run cleaner operations are likely to take share. - The market is rewarding execution discipline more than raw capacity. - The battery shift also suggests the installation business is moving up the value chain from hardware sales to advisory and system integration.

What's next: - Installers are entering 2026 with caution as price declines and subsidy uncertainty continue. - Many companies are shifting attention from volume to profitability. - The strongest installers are likely to be those that can package batteries, solar and other systems into complete energy solutions. - Mennan Suslu, VP of Sales at OpusFlow, said the companies growing now are the ones with their operations in order.
