Solar Energy Business Models: A Sustainable Systems Perspective

Abstract

The global transition towards low-carbon energy systems has positioned solar energy as a cornerstone of sustainable development, not only as a technology but as a catalyst for innovative business models. This paper examines solar energy business models through a sustainable systems perspective, emphasising the interconnections between technological innovation, economic viability, environmental stewardship, and social value creation. Moving beyond conventional utility-scale and ownership-based models, the study explores emerging configurations such as energy-as-a-service, community solar, peer-to-peer energy trading, and digitally enabled platform models. These approaches leverage system thinking to integrate generation, storage, distribution, and consumption while aligning stakeholder incentives across the value chain. The analysis highlights how sustainability-oriented business models enhance resilience, reduce lifecycle costs, support energy access, and contribute to decarbonisation goals. Furthermore, the paper underscores the role of policy frameworks, financial mechanisms, and digital technologies in shaping scalable and inclusive solar ecosystems. By adopting a systems perspective, the study provides a holistic understanding of how solar energy business models can balance profitability with long-term environmental and social objectives. The findings offer practical insights for policymakers, investors, and energy entrepreneurs seeking to design and implement solar solutions that are economically sustainable, environmentally responsible, and socially inclusive in diverse market contexts.
