Segment Insights

Service Type Insights

Why Did the Engineering & Design Services Segment Lead the Market in 2025?

The engineering & design services segment led the solar project development services market with a 32% share in 2025 because accurate system design, feasibility analysis, and site optimization are critical to maximizing project efficiency and returns. Advanced conceptual and detailed engineering are used to optimize plant layout and performance, as well as the selection of components and the system. Electrical, civil, and structural design services are provided to meet grid code requirements, safety standards, and long-term durability. As project complexity increased, such as with hybrid solar-storage plants, larger utility-scale facilities, and challenging terrains, the need for high-precision engineering became critical.

The financial modeling & PPA structuring segment is expected to grow at the fastest CAGR of 16.40% during the forecast period, driven by the need for precise project valuation, risk analysis, and bankable contract formats. The use of advanced financial models is becoming popular among developers, investors, and utilities to predict energy yields, returns, and long-term cash flows. As the process of corporate decarbonization accelerates, the PPA organization has become extremely important.

The feasibility studies & site assessment segment is expected to grow significantly in the coming years, as these services are crucial in the early stages to help developers determine land suitability, solar resource potential, and environmental restrictions. Developers also increasingly prioritize early-stage risk reduction and accurate project planning. Detailed assessments help optimize site selection, ensure regulatory and environmental compliance, and improve financial viability, making them essential for securing investments and long-term project success.

Technology Insights

What Made Solar Photovoltaic (PV) the Leading Segment in the Solar Project Development Market?

The solar photovoltaic (PV) segment led the market while holding a 85% share in 2025. This is mainly due to its declining installation costs, scalability across residential to utility-scale projects, and shorter development timelines. Advancements in PV efficiency and widespread policy support further accelerated adoption compared to other solar technologies.

The floating solar segment is expected to grow at the fastest CAGR of 22% during the forecast period due to land shortages, the rise in water-based projects, and increased efficiency caused by cooler operating environments. Installing solar systems on reservoirs, lakes, hydropower dams, and other industrial water bodies optimizes land use and reduces water evaporation. Floating PV is able to combine with hydropower plants to enhance grid stability and capacity. Thus, this technology is gaining attention in areas where land scarcity is a major concern.

Deployment Model Insights
