How Uttar Pradesh built its solar manufacturing base!

The headline indicates a buildout of solar manufacturing capacity in Uttar Pradesh, adding supply of solar hardware.

The trace

How it reaches your house.

Starting from Solar-Grade Polysilicon, we walked the supply graph hop by hop to the goods you buy and the companies you own. Each step is the engine’s reasoning, scored for confidence and cited where a source backs it.

First impact
Solar-Grade Polysilicon →Stands to benefit
China
China dominates this input's supply on the graph (93.5%), so a downstream solar-manufacturing buildout should lift demand for Chinese polysilicon.
84% confidence
Solar-Grade Polysilicon →Stands to benefit
Tongwei Co., Ltd.600438.SS
Tongwei's 26% share and low substitutability make it a strong near-term beneficiary of higher polysilicon demand.
76% confidence
Solar-Grade Polysilicon →Stands to benefit
GCL Technology Holdings3800.HK
GCL has a large supply position and long replacement lead time, so it should capture some of the added downstream demand for polysilicon.
Hop 2
GCL Technology Holdings →Prices rise
Solar-Grade Polysilicon (9N Purity)
The same downstream manufacturing expansion should tighten demand for 9N-purity polysilicon, where GCL has a 20% share and a 12-month replacement lead time, supporting higher prices.
61% confidence
GCL Technology Holdings →Prices rise
Solar-Grade Polysilicon
A buildout of solar hardware manufacturing in Uttar Pradesh should increase demand for GCL's standard solar-grade polysilicon; with an 18% share and low substitutability, the commodity's price likely firms.
58% confidence
Hop 3
Solar-Grade Polysilicon (9N Purity) →Stands to benefit
China
China supplies 91% of this input, so a solar-manufacturing buildout in Uttar Pradesh should channel most incremental polysilicon demand toward Chinese producers.
86% confidence
Solar-Grade Polysilicon (9N Purity) →Stands to benefit
Tongwei Co., Ltd.600438.SS
Tongwei's 26% share of solar-grade polysilicon means higher downstream solar-hardware demand should lift its sales volumes.
82% confidence
