AI Is Reshaping Solar Power, Review Finds, but Hurdles Remain

Artificial intelligence is rapidly changing how solar energy systems are developed and operated, according to a review published in the journal Discover Sustainability. The study, authored by Pouria Rezagholikhani and colleagues, surveys AI applications in solar energy over the last five years, from 2020 to 2025, and maps both the technology’s gains and the obstacles that remain.

The review identifies five major areas where AI techniques have accelerated system development and improved performance: power and energy forecasting, fault detection and maintenance, energy management, grid integration, and optimization. Across these areas, the authors describe a synergistic integration of AI with solar applications that has sped up development across the sector.

Two emerging technologies receive particular attention. Digital Twin systems, which create virtual replicas of physical solar installations, and Explainable AI, which the authors highlight as an emerging role alongside Digital Twins, are both identified as notable recent directions in the field.

The authors frame solar energy as a pivotal component of the global transition toward sustainable power, offering a robust alternative to fossil fuel systems with low environmental, ecological, and social impacts and contributing to energy security. Yet the review is candid about the barriers. AI deployment in solar systems confronts multifaceted technical, economic, environmental, and ethical challenges, including weather variability, high initial and operational costs, data security and privacy concerns, and potential job displacement.

Looking ahead, the review points to a next wave of AI technologies: Generative Artificial Intelligence, Causal AI, and Foundation Models, alongside a shift from centralized control toward autonomous and intelligent systems. If these transitions are navigated through responsible and innovative AI adoption, the authors conclude, they can further unlock the potential of AI in the solar sector and strengthen its role in advancing sustainable energy systems.
