Global Rooftop Solar PV Market Size

The size of the global rooftop solar PV market was worth USD 165.48 billion in 2025. The global market is anticipated to grow at a CAGR of 15.53% from 2026 to 2034 and be worth USD 606.74 billion by 2034 from USD 191.18 billion in 2026. 

Solar photovoltaic panels on rooftops are gaining popularity as they provide off-grid services and flexibility over the grid. Transmission of solar electricity to other sites is less efficient for rooftop solar due to the lack of smart grid infrastructure. The off-grid rooftop photovoltaic solar panel segment dominated the market in 2023. Rooftop solar photovoltaic systems are available through rental and a third-party model, resulting in increased demand for off-grid applications networks. The off-grid system allows you to store your solar energy in batteries for use when the power grid goes down or shuts down. Off-grid provides energy for your critical loads when the power grid is down.

MARKET GROWTH

The growing adoption of rooftop solar photovoltaic (PV) solar panels in residential and commercial installations for power generation using solar energy and increasing investments from key players in the solar industry for the development of photovoltaic solar panels are the main trends observed in the global rooftop solar photovoltaic market. This growing adoption is facilitated by regulatory policies, infrastructure development, strong growth in the gross domestic product (GDP), a large consumer base, low cost of power generation, and sustainable energy needs in economies emerging like China and India.

MARKET DRIVERS

The global rooftop solar PV market is expected to be guided by government policies and initiatives. In addition, the growing demand for photovoltaic solar panels from different regions has led to the production of inexpensive modules and thus caused the prices of solar modules to fall around the world. This is expected to further contribute to capacity additions for solar PV installations in the future. Government and private companies are expected to adopt these modules in residential and commercial establishments, thus stimulating their demand in the future.

MARKET RESTRAINTS

Rooftop solar PV systems require capital investment and solar radiation over a significant period. The Energy Payback Time (EPBT) for 2.5kW rooftop solar systems is typically around two years, which is likely to inhibit the growth of the global rooftop solar PV market during the period forecast.

SEGMENTAL ANALYSIS

By Technology Insights

The thin film segment held a dominant market share of over 38% in 2025 and is expected to grow at the highest CAGR during the outlook period. The growth can be attributed to making thin films from light and flexible materials, high durability, and narrow design. Photovoltaic solar energy for thin film roofs finds application mainly in the commercial sector, as they have lower installation costs due to their low weight. The crystalline silicon segment held a 33.4% share of the market revenue in 2023.

By Application Insights

The industrial sector accounted for the largest share of revenue with around 43% in 2025 and is expected to maintain its dominance during the foreseen period. Solar rooftop energy provides energy for industrial heating and cooling, which would otherwise be obtained from fossil fuels which generate harmful emissions. Increasing industrialization in developing economies is expected to significantly boost market demand during the forecast period.

The residential segment is anticipated to rise at the highest CAGR during the estimated period. Off-grid rooftop solar photovoltaics equipped with a battery energy storage system provides reliable secondary power in residential homes, driving product demand across the segment. The deployment of large-scale storage systems to protect against peak demand power changes has resulted in the adoption of an oversized rooftop solar photovoltaic system to store the desired energy in batteries.

The commercial segment accounted for 33.42% of the market revenue share in 2025. The increasing penetration of solar photovoltaic energy on the roofs of hospitals, hotels, and corporate offices, as well as the growing demand for energy centers, databases, and communications stations, are driving product demand in the business sector.

By Grid Type Insights

The on-grid segment accounted for the largest revenue share of over 87% in 2025, as it offers the advantage of transferring the excess electricity generated to the grid and there is no need to install storage by a battery near the system source. The non-complexity of grid-connected rooftop photovoltaic systems coupled with low operation and maintenance costs will certainly generate positive demand for the market growth of the grid-connected segment.

The off-grid segment is expected to achieve the highest CAGR during the envisioned period due to increasing demand for electricity from remote locations coupled with strict regulatory regimes for distributed power generation.

REGIONAL ANALYSIS

The Asia-Pacific rooftop solar PV market accounted for the largest revenue share of over 35% in 2025 and is expected to continue to dominate during the conjecture period. China was the biggest contributor to revenue generation in the market. Favorable government policies offering financial incentives and subsidies for solar PV projects as well as the presence of large market players are among the important factors contributing to the growth of the market in China.

The European rooftop solar PV market captured a revenue share of over 29.47% in 2025. The UK recorded the largest revenue share in Europe. The growing trend to generate energy from renewables adds to the increase in solar PV capacity on rooftops. In addition, stringent regulatory reforms regarding the deployment of clean energy are stimulating the growth of the regional market.

North American rooftop solar PV market held a significant market share, with the United States being the main contributor to regional growth revenues. The growing need for electricity generation from clean fuels, coupled with the growing capacity of residential solar power, is expected to improve product penetration across the area in the coming years.
