Research Methodology
Step 1: Ecosystem Creation
We begin by mapping the complete ecosystem of the India Rooftop Solar Market across demand-side and supply-side entities. On the demand side, entities include commercial and industrial power consumers (manufacturing plants, warehouses, logistics parks, IT parks, hospitals, malls, and office campuses), residential homeowners and housing societies, institutional users such as schools, universities, government buildings, railways, airports, and public-sector undertakings, as well as real estate developers integrating rooftop solar into new projects. Demand is further segmented by consumer category (C&I, residential, institutional), system size (small, mid-scale, large rooftop), installation context (new building vs retrofit), and ownership model (CAPEX vs OPEX / RESCO).
On the supply side, the ecosystem includes rooftop solar EPC companies, integrated solar developers, inverter and module manufacturers, mounting structure suppliers, electrical balance-of-system providers, financing partners, asset owners under OPEX models, operations and maintenance service providers, and local distribution companies (discoms) responsible for approvals, metering, and grid interconnection. Regulatory bodies, state electricity regulatory commissions, and subsidy-implementing agencies are also mapped as critical ecosystem participants. From this mapped ecosystem, we shortlist 8–12 leading rooftop solar EPCs and developers based on installed capacity track record, geographic presence, segment focus, execution capability, financing access, and after-sales service strength. This step establishes how value is created and captured across system design, procurement, installation, grid integration, financing, and long-term asset operation.
Step 2: Desk Research
An exhaustive desk research process is undertaken to analyze the India rooftop solar market structure, demand drivers, and segment behavior. This includes reviewing national and state-level renewable energy policies, rooftop solar program guidelines, net-metering and gross-metering regulations, discom interconnection frameworks, and subsidy mechanisms. We assess electricity tariff trends across consumer categories, grid reliability indicators, and regional variations in rooftop solar adoption.
Company-level analysis includes review of EPC and developer business models, project portfolios, customer mix, ownership structures, and technology preferences. We examine rooftop availability trends across industrial, commercial, and residential buildings, along with typical system sizing, cost benchmarks, and payback expectations. Regulatory and compliance dynamics such as electrical safety standards, fire clearance norms, inverter certification requirements, and structural considerations for rooftop loading are also analyzed. The outcome of this stage is a comprehensive industry foundation that defines segmentation logic and establishes the assumptions required for market sizing, penetration analysis, and long-term outlook modeling.
Step 3: Primary Research
We conduct structured interviews with rooftop solar EPC companies, developers, equipment suppliers, financing partners, commercial and industrial consumers, residential installers, and energy consultants. The objectives are threefold: (a) validate assumptions around demand concentration by consumer segment and region, (b) authenticate segment splits by system size, ownership model, and installation type, and (c) gather qualitative insights on pricing trends, approval timelines, discom engagement, execution challenges, and customer expectations around system performance and service quality.
A bottom-to-top approach is applied by estimating the number of rooftop installations and average system capacity across key consumer segments and regions, which are aggregated to derive the overall market view in capacity and value terms. In selected cases, disguised buyer-style interactions are conducted with installers and EPCs to validate field-level realities such as quotation timelines, financing availability, subsidy disbursement delays, and common operational bottlenecks during installation and commissioning. These insights are used to refine adoption assumptions and competitive positioning.
Step 4: Sanity Check
The final stage integrates bottom-to-top and top-to-down approaches to cross-validate market size estimates, segmentation splits, and forecast assumptions. Demand estimates are reconciled with macro indicators such as electricity demand growth, rooftop solar targets, urbanization trends, commercial real estate expansion, and industrial capacity additions. Assumptions related to tariff inflation, policy continuity, net-metering availability, and financing access are stress-tested to assess their impact on adoption rates.
Sensitivity analysis is conducted across key variables including regulatory stability, discom cooperation levels, capital cost reduction trajectories, and adoption of OPEX models. Market models are refined until alignment is achieved between supplier execution capacity, financing availability, regulatory throughput, and buyer demand pipelines, ensuring internal consistency and robust directional forecasting through 2035.
