結論と提言

Global Distributed Solar Power Generation Market size was valued at USD 140.3 billion in 2023 and is poised to grow from USD 149.98 billion in 2024 to USD 255.77 billion by 2032, growing at a CAGR of 6.9% during the forecast period (2025-2032).

The shift from traditional centralized power generation to distributed solar power systems is gaining traction as a sustainable alternative, motivated by environmental concerns and inefficiencies in existing models. These decentralized networks, comprising residential rooftops, commercial installations, and community solar gardens, empower consumers to generate their own electricity, thus decreasing reliance on fossil fuels and enhancing energy security. The significant reduction in solar technology costs has been a major driver for market expansion, making solar energy more accessible. Increased awareness of solar power's advantages, such as lower electricity costs and reduced carbon emissions, further propels adoption. Additionally, factors like enhanced local manufacturing and a surplus of foreign panels contribute to decreased installation costs, benefiting both individual and commercial users.
