## Overview

**New York, NY – August 20, 2025 –** The Global Rooftop Solar PV Market is projected to reach **USD 109.2 billion** by **2034,** growing from **USD 61.0 billion** in **2024** at a **CAGR** of **6.0%** from **2025** to **2034.** The **Asia Pacific** region led with **USD 21.2 billion** in growth, driven by robust policy support and abundant solar potential. Rooftop Solar Photovoltaic (PV) systems involve solar panels installed on residential, commercial, or industrial building rooftops to convert sunlight into electricity. This power can be used on‑site, stored in batteries, or fed into the grid, depending on system design and local regulations. The market is expanding due to declining solar panel costs, supportive government incentives, and rising conventional electricity prices. It encompasses panel manufacturers, installers, storage integrators, and utility partners. Rooftop PV is especially appealing in areas with high solar exposure and unreliable grids, where energy independence and cost savings drive adoption. Key growth drivers include the global push for renewable energy to cut greenhouse gas emissions. Rooftop PV systems generate clean electricity at the point of use, reducing transmission losses and supporting climate goals. Advances in panel efficiency and energy storage have further boosted system viability. Recent developments highlight the role of public funding and policy. For instance, the Trump‑era EPA aimed to reclaim **$7 billion** in rooftop solar grants, while India’s MNRE allocated **₹20 million** to foster solar startup innovation. In the UK, Great British Energy committed **£10 million** to expand rooftop solar access. Rising electricity costs and energy insecurity are fueling demand across developed and developing regions. Households and businesses are adopting rooftop PV for cost savings and reliability, with urbanization and smart city projects further accelerating uptake. Financial and institutional support is also growing. Dugar Finance, a rooftop solar‑focused NBFC, raised $3 million in debt funding to support installations. Meanwhile, Telangana’s **81 MW** rooftop solar tender reflects increasing government‑led efforts to promote decentralized solar adoption.
