The increasing adoption of renewable energy solutions is expected to drive growth in the rooftop solar PV market in the coming years. Renewable energy adoption refers to the growing use of clean and sustainable energy sources, particularly solar, wind, and other non-fossil electricity generation, to meet rising power demand. This surge in renewable energy adoption is driven by intensified efforts from governments and private stakeholders worldwide to reduce greenhouse gas emissions, achieve climate objectives, and promote sustainable energy access. The rooftop solar PV market supports the adoption of renewable energy solutions by offering accessible, decentralized clean power through distributed rooftop installations, which complement grid and utility-scale generation while enabling consumers to produce their own electricity. For instance, in June 2024, according to the Department for Energy Security and Net Zero, a UK government ministerial department, renewable electricity generation in the first quarter of 2024 increased by 3.7 percent to 39.2 TWh, mainly driven by onshore wind, raising renewables’ share of total generation to 50.9 percent and installed capacity by 2.5 GW compared to the first quarter of 2023. Therefore, the increasing adoption of renewable energy solutions is fueling the growth of the rooftop solar PV market.

Major companies operating in the rooftop solar photovoltaic market are focusing on technological advancements, such as n-type i-TOPCon technology, to enhance cell efficiency, improve module reliability, and maximize energy generation for residential and commercial installations. N-type i-TOPCon technology refers to an advanced solar cell architecture that minimizes recombination losses, increases conversion efficiency, and delivers better performance in high-temperature and low-light conditions. For instance, in January 2024, Trina Solar Co. Ltd, a China-based solar energy solutions provider, introduced the Vertex S N-Type Dual-Glass Modules for commercial and industrial rooftop applications. These modules incorporate n-type i-TOPCon technology along with a durable dual-glass design, offering high power output, improved resistance to potential-induced degradation, and extended service life. These attributes enable installers and end users to achieve greater energy yields while ensuring reliability and sustainability. The launch highlights the growing shift toward high-efficiency, long-lasting solar modules in rooftop applications, helping businesses, industries, and homeowners optimize rooftop energy generation, lower carbon emissions, and support the transition to clean and sustainable energy solutions.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs have had a mixed impact on the rooftop solar photovoltaic market by increasing costs of imported photovoltaic modules, inverters, and balance of system components. These tariffs have raised project costs and slowed adoption in price-sensitive residential and commercial segments, particularly in Asia-Pacific and emerging markets dependent on imports. However, tariffs have encouraged domestic manufacturing and localization of solar components in regions such as North America and India. In the long term, this supports supply chain resilience and strengthens local solar ecosystems while promoting innovation in cost-efficient rooftop solutions.

Rooftop solar photovoltaic refers to the decentralized generation of electricity using photovoltaic panels installed on residential, commercial, or industrial rooftops, which convert sunlight directly into usable electrical energy. It is intended to reduce dependence on grid electricity and fossil fuels, lower greenhouse gas emissions, and promote cost-effective clean energy production at the point of consumption while supporting energy security and sustainability.

The main components of rooftop solar photovoltaic systems include photovoltaic modules, inverters, mounting structures and solar racking, balance of system components, energy storage systems, and monitoring and smart energy management systems. Photovoltaic modules are devices that generate electricity directly from sunlight using the photovoltaic effect. The key technologies include thin film and crystalline silicon. Deployment types include terrace-mounted and pole-mounted systems. The various grid configurations comprise off-grid and grid-connected systems, and these are utilized by different end users such as residential, industrial, and commercial sectors.
