The Mine-to-Module Supply Chain: A Complete Saudi Solar Ecosystem

The Saudi Solar Boom: An Unprecedented Opportunity

Saudi Arabia’s solar transformation is happening at a breathtaking pace. In 2020, the country had next to no renewables. By the end of this year, it’s predicted to have 12 gigawatts of solar, and the Kingdom has broken into the top 10 global markets for annual new solar for the first time . The target is clear: 50% of electricity from renewables by 2030, with Rystad projecting more than 70 gigawatts installed by the end of the decade .

The economics are driving this shift. Solar is now so cost-competitive that it makes financial sense even for the world’s largest oil exporter . Saudi Arabia benefits from abundant sunshine, cheap and plentiful land, and economies of scale from vast installations . ACWA Power, Saudi Aramco, and other major players have announced $8.3 billion investments into 15 gigawatts of renewables, dominated by solar .

But this rapid deployment raises a critical question: where will all the solar panels come from?

The answer lies in a national capability that few countries possess—the ability to build a complete solar ecosystem from mine to module. Saudi Arabia’s vast mineral wealth, combined with its ambitious industrial development plans, creates the foundation for an integrated solar solutions Saudi value chain that captures economic value at every stage.

At Darkstone Group, our four divisions represent exactly this integrated capability. Our Mining division provides the critical minerals essential for solar technology; our Industrial Construction division builds the manufacturing facilities; our Solar division installs the systems; and our Industrial O&M division maintains them for 25+ years. This renewable energy ecosystem KSA is a story of national capability, local content, and complete economic value retention that is unique to our company.

The Vision: From Sand to Solar Panels

The Solar Panel Value Chain

The journey from Saudi minerals to solar modules spans multiple stages, each requiring specialized capabilities:

Stage 1: Mineral Extraction

• High-purity silica sand (silicon dioxide) is the primary raw material for solar panels

• The Arabian Shield holds significant deposits of silica, copper, silver, aluminum, and rare earth elements essential for solar manufacturing

• Darkstone’s Mining division is exploring and developing these critical mineral resources

Stage 2: Material Processing

• Silica is refined into high-purity polysilicon (99.9999% purity) for semiconductor-grade use

• Copper and silver are processed for electrical conductors

• Aluminum is refined for structural components and frames

• Glass is manufactured for panel encapsulation

Stage 3: Solar Cell & Module Manufacturing

• Polysilicon is processed into wafers, then into photovoltaic cells

• Cells are assembled into modules with glass backing, encapsulants, and junction boxes

• Darkstone’s Construction division builds the factories where this manufacturing happens

Stage 4: System Installation

• Modules are combined with inverters, mounting structures, and trackers

• Darkstone’s Solar division delivers turnkey installation—from civil works to electrical integration

Stage 5: Operations & Maintenance

• Solar systems require 25+ years of monitoring, cleaning, and maintenance

• Darkstone’s O&M division ensures optimal performance throughout the system lifecycle

The National Imperative: Technology and Value Chain Localization

Saudi Arabia’s energy strategy explicitly prioritizes local content development. The King Abdullah City for Atomic and Renewable Energy (K.A.CARE) leads initiatives focused on Technology Localization and Value Chain Localization, aiming to increase local content by developing and demonstrating promising renewable energy technologies and studying value chains to identify promising opportunities for the private sector .

The Renewable Energy Technologies Localization Initiative aims to “increase the local content for the renewable energy technologies sector by accelerating the growth of the local private sector and support local companies to develop renewable energy products, applications and services” . This includes developing and owning renewable energy desalination technologies, energy storage, and concentrated solar thermal technologies .

Strategic Partnerships and Investment efforts “encourage local investment, attract foreign investment, build alliances and strategic partnerships locally and internationally to contribute to increasing local content, localizing technology, and positively impacting the national economy” . This creates a direct opportunity for companies like Darkstone to partner with international technology providers and establish local manufacturing capacity.

Lessons from the World: Rio Tinto’s Circular Mining Model

Global mining leaders are already demonstrating the viability of closed-loop mineral supply chains. Rio Tinto has energized a new 25-megawatt solar plant at its Kennecott copper operations in Utah, showcasing a circular critical-minerals supply chain in which tellurium produced at the site is used to manufacture the panels now powering it .

Key Metrics from the Kennecott Project:

• Solar Capacity: 30 MW (5 MW + 25 MW expansion) 

• Annual Generation: Enough to power 1,026 American homes 

• Emissions Reduction: 6% reduction in Scope 2 emissions (20,000 tonnes CO₂e) 

• Supply Chain: Tellurium mined at Kennecott → processed by 5N Plus Inc. in Canada → panels manufactured by First Solar → installed at Kennecott 

Nate Foster, Managing Director of Rio Tinto Kennecott, stated: “This new solar plant is more than a source of renewable power for our operations; it’s a demonstration of circularity and supply chain resilience. By mining copper and tellurium… and using that tellurium in the panels powering our site, we’re proving how domestic critical minerals support renewable energy manufacturing” .

This model directly parallels what Darkstone can achieve in Saudi Arabia: mining the minerals, building the facilities, installing the systems, and operating them for decades.

The Critical Minerals Foundation

Saudi Arabia’s Arabian Shield holds vast deposits of the minerals essential for solar technology:

Copper: Essential for wiring, inverters, and electrical systems. An electric vehicle contains nearly four times more copper than a conventional car.

Silver: Used in photovoltaic cell contacts and conductive pastes.

Silicon: The base material for most photovoltaic cells.

Aluminum: Structural components, mounting systems, and frames.

Rare Earth Elements: Advanced solar technologies and energy storage systems.

The supply chain for high-purity silica (HPQ) remains highly fragmented globally, creating a first-mover opportunity for countries that can integrate production . By controlling the entire journey—from mineral extraction through processing to finished products—integrated companies can capture margins at every stage, ensure quality control, and reduce exposure to commodity price swings .

The Vertical Integration Advantage

In the critical minerals sector, a vertically integrated business strategy means more than just mining. It’s about controlling the entire journey of a material—from the ground, through processing and logistics, to delivery as a high-value product to end users .

Benefits of Vertical Integration for Darkstone:
