Global Supply Chain
Raw material → electricity · who dominates each layer
Country dominance by segment
China dominates upstream (polysilicon, wafers, cells). India is competitive in EPC, IPP, grid, and emerging in cells/modules.

Segment deep-dives
Quartz / Silica
High-purity quartz and silica feedstock used to produce metallurgical-grade silicon and ultimately polysilicon.
Polysilicon
Ultra-purified silicon (>99.99999%) made via Siemens or fluidized-bed processes; primary feedstock for wafers.
Ingots & Wafers
Polysilicon is crystallized into ingots then sliced into wafers — the substrate for solar cells.
Solar Cells
Wafers are processed into electricity-generating photovoltaic cells (PERC, TOPCon, HJT, etc.).
Solar Modules
Cells are assembled into panels using glass, encapsulants, backsheets, frames and junction boxes.
Solar Glass
Low-iron tempered glass with anti-reflective coating; ~6–7% of module BOM.
Encapsulants & Backsheets
EVA/POE films and polymer backsheets that protect cells from moisture, UV and thermal stress.
Aluminium Frames
Anodised aluminium frames provide structural support for modules; ~10–12% of module BOM.
Inverters
Convert DC from panels into AC; the brain of every solar plant.
Trackers & Mounting
Single-axis and fixed-tilt structures that hold modules and maximize generation.
Cables & Conductors
DC cables, AC cables, conductors and evacuation cabling required at every solar project.
EPC
Engineering, procurement and construction firms that build utility-scale and C&I solar projects.
IPP / Developer
Independent power producers owning and operating solar assets, selling power under PPAs or merchant.
Rooftop Solar
Distributed generation on residential, commercial and industrial roofs, with net or gross metering.
C&I Open Access
Solar power sold directly to commercial and industrial customers through open access or captive structures.
Transmission & Grid
HV/EHV transmission lines, substations, transformers and grid automation required to evacuate renewable power.
Storage
Battery energy storage (BESS) and pumped hydro to shift solar from daytime to evening demand.
Financing
Renewable project finance, refinancing, green bonds, securitisation and InvITs.
Power Trading
Exchange-based power markets including DAM, RTM, GTAM and REC trading.
Smart Metering
Smart prepaid and post-paid meters required for net/gross metering, DISCOM modernization and ToD tariffs.
Recycling
End-of-life solar module recycling and re-use of aluminium, glass, silicon and silver.
