Interview with Alfredo Beggi, Director of Sales & Strategic Development at Stern Energy.
What are the main areas of activity of the company?
Alfredo Beggi: Stern Energy operates across four strategic pillars that together cover the entire lifecycle of a photovoltaic asset: Operation & Maintenance, Revamping & Repowering, Construction and Asset Management.
This integrated approach ensures that each plant — new or existing — achieves optimal performance, reliability, and long-term value creation. By combining advanced engineering, extensive field experience, and data-driven management, we support the sustainable growth and operational excellence of solar portfolios throughout their lifecycle.
What are the ranges of products/services?
A.B: Our service offering spans the full operational journey of a photovoltaic asset, ensuring continuity, performance and durability.
Construction: Design and execution of ground-mounted and rooftop plants, supported by an in-house engineering team with strong technical expertise and proven experience in coordinating complex project workflows, ensuring high-quality and timely delivery.
Revamping & Repowering: Upgrades designed to improve performance, optimize configurations and extend asset lifetime — essential interventions in a rapidly evolving technological landscape.
Operation & Maintenance: Comprehensive technical management and continuous monitoring, including preventive and corrective maintenance, rapid-response troubleshooting, and advanced performance analytics to ensure maximum availability and yield.
Asset Management: Support in maximizing long-term value through compliance oversight, technical-administrative monitoring, and integrated reporting, ensuring transparency, performance, and operational integrity.
Across all service lines, Stern Energy delivers a unified, data-driven approach to guarantee high performance and sustainability throughout every phase of a solar project.
What is the state of the market where you are currently active?
A.B: The European photovoltaic market is experiencing strong and sustained growth, driven by accelerating decarbonization targets. Expansion is evident across residential, commercial-industrial, and especially utility-scale segments, supported both by the development of new large-scale plants and by significant revamping and repowering activity on existing assets.
Rapid advancements in trackers, inverters, and photovoltaic modules have improved plant efficiency, reduced CAPEX, optimized land use, and increased energy yield. These shifts have strengthened project fundamentals for investors and created new opportunities for owners and operators to enhance performance and extend asset lifetime.
At the same time, the rising installed capacity across Europe has generated a structural demand for high-quality Operation & Maintenance and Asset Management services, with reliability, availability, and long-term value protection now central to asset strategy.
Active across the full lifecycle of solar assets, Stern Energy supports clients from development through long-term operation, leveraging field know-how, engineering capabilities, and a culture of continuous improvement to help investors, IPPs, and industrial partners achieve sustainable growth and superior performance in a rapidly evolving market.
