Saudi 12.538-MW solar-irrigation project adds over 5% capacity with reinforced back-contact panels

Advanced solar technologies are breaking ground in sustainable agricultural practices.

Globally, sectors are under pressure to decarbonize under strict climate regulations.

In Saudi Arabia, under its Vision 2030 target, agriculture is being addressed directly by incorporating photovoltaics across desert farmlands.

By scaling similar anti-dust technology, adding smart water management, and expanding public-private partnerships, nationwide decarbonization can be accelerated.

The high-tech design and engineering ensure minimal impact from the harsh desert climate while maximizing clean energy output.

What does this advanced infrastructure entail, and how does it work to support national goals?

How desert regions have historically struggled to decarbonize

The global shift toward renewable energy has achieved significant milestones in recent years.

In 2020, renewables experienced a record year, with solar power generation becoming the most affordable source of electricity in history.

This year, the transition began to focus on grid integration rather than raw capacity generation.

Despite these milestones, some regions still struggle to decarbonize and have been for years.

Desert nations like Saudi Arabia exemplify this, as heavy reliance on fossil fuels and extreme ambient temperatures complicate things.

Saudi Arabia is a rapidly developing country experiencing annual carbon dioxide emissions approaching 690 million tons.

This major footprint is driven by industrial growth and surging power demands.

However, it also stems from a longstanding history with natural gas and oil for electricity generation.

The region holds major hydrocarbon reserves, which have traditionally powered domestic grids and massive infrastructure.

Now, the nation is actively working to overcome this carbon-heavy legacy.

The limitations of standard green technologies

Despite the nation rushing to restore its oil pipeline capacity, decarbonization has become a priority.

Under Saudi Arabia’s Vision 2030 national framework, environmental preservation, sustainability, and economic diversification are key pillars.

The primary goal is to source at least half of the nation’s power from renewables by 2030.

The main strategy entails rapidly expanding clean capacity through major wind and solar initiatives.

However, traditional green technologies like standard solar panels face engineering difficulties when deployed across desert environments.

Conventional panels are not designed for extreme desert conditions.

Solar cells experience significant voltage drops and power losses under intense ambient heat.

Meanwhile, persistent dust buildup blocks vital sunlight and creates abrasive layers that lower efficiency.

These conditions also accelerate component degradation, causing micro-cracks and a shorter operational lifespan.

The only way to truly decarbonize is to deploy resilient renewable infrastructure designed for harsh desert climates.

Fortunately, that is exactly what LONGi began to do.

Advanced agrivoltaic systems in Saudi Arabia

Saudi Arabia is investing in smart solar technologies, some of which are being paired with agriculture.

In a partnership with SDC Group, LONGi deployed its advanced photovoltaics in a 12.538-megawatt farming irrigation project.

The innovative agrivoltaic framework powers water systems sustainably across desert farmland.

At the center of the project are Hi-MO X10 Anti-Dust modules.

It was built on LONGi’s advanced Hybrid Passivated Back Contact (HPBC 2.0) cell technology. It also uses high-strength TaiRay wafers.

The front surface does not have metal busbars to block sunlight, which maximizes light absorption.

The system’s specialized engineering advantages

Special framing and high-density packaging ensure minimal dust accumulation and stable output during partial shading.

Superior temperature coefficients enable panels to resist intense desert heat degradation.

Generating capacity is increased by over 5%, cutting local farm power costs by over 30% within six months of operation.

The project is fully completed and operational, highlighting the viability of high-efficiency desert agriculture.

Its success lays the groundwork for greater advanced agrivoltaic growth across Saudi Arabia. This will be key to supporting the nation’s food and water security.

By scaling similar anti-dust technology, adding smart water management, and expanding public-private partnerships, nationwide decarbonization can be accelerated.

Ultimately, combining solar power generation with agriculture presents distinct benefits for regions with similar desert climates.
