The distributed PV systems segment is anticipated to grow at the fastest CAGR during the forecast period. Increasing retail electricity tariffs are improving the financial attractiveness of distributed and rooftop PV systems. As grid electricity becomes more expensive, households and businesses can reduce their electricity bills by generating and consuming solar power onsite. Higher tariffs increase the savings from self-consumption and can shorten PV system payback periods. Therefore, the rising electricity costs are encouraging residential, commercial, and industrial customers to invest in grid-connected rooftop solar installations.

Component Insights

The solar modules segment led the market with the largest revenue share of 51.2% in 2025 and is anticipated to grow at the fastest CAGR during the forecast period. The adoption of larger wafer sizes and higher-power solar modules is improving the economics of grid-connected PV projects. Larger modules can deliver greater power output per unit, reducing the number of modules required to achieve a specific project capacity. This can lower requirements for mounting structures, cables, connectors, and installation labor. Consequently, developers can reduce balance-of-system costs, simplify installation, improve land utilization, and lower overall project costs, particularly for large utility-scale solar installations.

The PCU/Inverters segment is anticipated to grow at a significant CAGR during the forecast period. The expansion of utility-scale solar farms is increasing demand for high-capacity inverter solutions. Large PV projects require inverters capable of converting substantial amounts of DC electricity generated by thousands of solar modules into grid-compatible AC electricity. Central and high-power string inverters enable efficient power conversion while supporting grid management and monitoring.

PV Module Type Insights

The monocrystalline segment accounted for the largest market revenue share of 80.9% in 2025 and is anticipated to grow at the fastest CAGR during the forecast period. Monocrystalline modules offer higher power output per unit area than lower-efficiency PV technologies. This makes them particularly valuable where available rooftop or land space is limited. Residential buildings, commercial facilities, and urban industrial sites can generate more electricity without requiring larger installation areas. Similarly, utility-scale developers can maximize energy generation from constrained land parcels. Higher power density also reduces the number of modules, mounting structures, cables, and installation components required for a given capacity, helping improve overall system economics and project efficiency.

The polycrystalline segment is expected to grow at a significant CAGR during the forecast period. Polycrystalline solar cells are manufactured by melting silicon and casting it into blocks, which are then sliced into wafers. This process is generally simpler and involves fewer processing steps than producing high-purity monocrystalline wafers. Lower manufacturing complexity can reduce equipment, energy, and production costs. Subsequently, polycrystalline modules can remain attractive in price-sensitive markets and solar projects where minimizing upfront investment is more important than achieving the highest possible efficiency.
