REC solar panels are manufactured in Singapore. REC produces its solar panels in a highly automated manufacturing facility located in Tuas, Singapore. The company was founded in Norway in 1996 and is now owned by Reliance Industries of India, but all panel production, including the REC Alpha series, takes place in Singapore.
Who Makes REC Solar Panels: Company Background
Founded in Norway in 1996
REC Group’s roots trace back to a Norwegian company called Fornybar Energi AS, established in 1996. The solar pioneer began operations during a period when renewable energy was gaining traction globally. Following a strategic merger in September 2000, Fornybar Energi AS combined with ScanWafer AS and SolEnergy AS to form what became the Renewable Energy Corporation.
The company produced its first solar cell in 1997, just one year after its founding. Norway’s abundant hydroelectricity made it an attractive location for silicon production, providing low-cost energy for manufacturing processes. In fact, REC reportedly continues to use Norwegian silicon in its solar panels despite shifting production facilities elsewhere.
During its early years in Norway, REC established manufacturing operations in multiple locations. In 2002, REC ScanCell started producing multicrystalline solar cells in Narvik, supplying the sister company REC ScanModule in Glava, Arvika. This vertical integration allowed REC to control quality across the production chain.
Current Ownership Structure
REC’s ownership has changed hands several times, though these transitions haven’t compromised product quality. In 2015, the Norwegian company Elkem acquired REC for $778 million. However, Elkem itself had been owned by China National Bluestar Group (ChemChina) since 2011, making REC indirectly Chinese-owned.
The most significant ownership change occurred on October 10, 2021, when Indian conglomerate Reliance Industries announced its subsidiary, Reliance New Solar Energy Limited, had acquired complete control of REC from China National Bluestar Group for $771 million. At year-end 2023, Reliance New Energy Ltd owned 100% of the shares in REC Solar Holdings AS.
This acquisition by Reliance brought substantial financial backing and ambitious expansion plans. The new ownership committed to growing REC’s capacity to over 5 GW within 2 to 3 years across Singapore, Europe, and the USA. In India specifically, Reliance plans to deploy REC’s technology at the Dhirubhai Ambani Green Energy Giga Complex in Jamnagar, starting with 4 GW annual capacity and eventually reaching 10 GW per annum.
Global Operations and Market Presence
While REC maintains its headquarters in Norway, honoring its Scandinavian heritage[12], the company operates with a truly global footprint. The operational headquarters are located in Singapore, where the primary manufacturing facility produces solar cells and modules.
REC has established regional hubs across North America, Europe, and Asia-Pacific to serve its diverse customer base[22]. This geographic distribution allows the company to provide localized support and respond quickly to market demands in different regions.
The company’s workforce reflects its international scope. According to different sources, REC currently employs more than 1,300 employees worldwide, with other reports indicating over 2,000 employees. This substantial team supports manufacturing operations, research and development, sales, and customer service across multiple continents.
In 2023, REC announced the REC@NUS Corporate R&D Laboratory for Next Generation Photovoltaics project with the National University of Singapore. This partnership demonstrates the company’s ongoing commitment to innovation and technological advancement in solar panel manufacturing.
Where Are REC Solar Panels Manufactured Today
Primary Manufacturing Facility in Singapore
REC solar panels are manufactured at a vertically integrated production facility in Tuas, Singapore. The facility officially opened in November 2010 and represents one of the largest solar manufacturing complexes globally. This modern facility produces solar wafers, cells, and modules under one roof, giving REC exceptional control over quality at every production stage.
The Singapore plant currently operates with 600MW of production capacity for the Alpha Pure range. REC plans to expand this capacity to 1.3 GW, with an additional 600MW dedicated to manufacturing the company’s latest Alpha Pure-R line. Following the Reliance Industries acquisition, REC aims to scale production to more than 5GW across Singapore, Europe, and the US.
Autonomous, intelligent robots produce REC solar panels using Industry 4.0 technology, drastically reducing human error and setting quality standards for competitors. This high level of automation distinguishes REC from many other panel manufacturers. The facility also practices what it preaches: a 2.6 million kWh rooftop solar installation powers approximately 550 four-room apartments’ worth of electricity annually, saving 1,400 tons of carbon emissions each year.
The Singapore Building and Construction Authority awarded the facility its ‘Green Mark’ designation, recognizing achievements in energy efficiency, project development, and environmental protection. Initially, REC employed about 1,500 people at the Tuas plants, though workforce numbers have evolved as automation increased.
Why Singapore Was Chosen for Production
Singapore’s selection as REC’s primary manufacturing hub stemmed from strategic advantages. The modern island-nation offers world-class infrastructure, stable governance, and a strong business ethics framework. As Singapore continues leading technological advancements, REC benefits from being located in an innovation-focused environment.
The facility represented the largest clean tech investment ever made in Singapore at the time, totaling 2.5 billion Singapore dollars (approximately €1.3 billion). This massive investment reflected confidence in Singapore’s ability to support advanced manufacturing operations.
The Singapore location also provides excellent access to growing Asian markets. REC recognized that demand would diversify away from European markets toward Asia and the United States. By establishing operations in Southeast Asia, the company positioned itself closer to these expanding markets while maintaining the ability to ship panels worldwide from the strategically located port city.
Closure of Norwegian Manufacturing Plants
In November 2023, REC closed its polysilicon production activities in Kristiansand and Porsgrunn, Norway. This closure affected around 250 workers and marked the end of REC’s Norwegian manufacturing operations. However, the closure had no impact on cell and module operations in Singapore.
High electricity prices drove the decision to shutter Norwegian facilities. After restarting production in March 2023, REC paused operations again in August before permanently closing. REC’s activities in Norway accumulated losses totaling NOK 335 million (USD 31.20 million). The closure eliminated 2.4GW of polysilicon production capacity from Europe, leaving only German producer Wacker Chemie as a major European polysilicon manufacturer standing.
This wasn’t REC’s first Norwegian closure. In 2012, the company shut down its wafer plant at Heroeya, eliminating 460 jobs as competition from Chinese manufacturers drove down prices. In effect, REC’s Norwegian manufacturing chapter closed after years of struggling against global price pressures and unfavorable local production economics.
REC Solar Panel Manufacturing Process and Technology
Advanced Manufacturing Equipment and Automation
REC’s Singapore facility employs autonomous, intelligent robots using Industry 4.0 technology to produce solar panels. This automation level drastically reduces human error and sets quality benchmarks that competitors struggle to match. The integrated manufacturing process handles everything from wafers to cells to modules under one roof.
Multiple automated inspection systems monitor production continuously. Infrared cameras detect inclusions and cracks in wafers, while sawmark detection systems identify defects that could weaken wafers or cause electrical shunts. Camera systems inspect for chips and edge defects throughout the cell and module assembly lines. At the module level, inspectors check cells, strings, matrices, and laminates using automated vision systems that catch cracks, spacing issues, misalignment, and contamination.
Specifically, REC performs 100% inline cell IR imaging and dark IV testing on every cell produced. These quality measures aren’t widespread across the solar industry. Each module undergoes I-V curve testing, maximum power verification, resistance testing, and hi-pot testing for electrical insulation before shipping.
Quality Control Standards
REC operates three quality control checkpoints: Incoming Quality Control (IQC), In-process Quality Control (IPQC), and Outgoing Quality Assurance (OQA). The company’s internal testing runs twice as stringent as International Electrotechnical Commission (IEC) standards. In designing new products, REC works not only to meet international standards but surpass them.
The results speak volumes. Out of approximately 4 million panels manufactured yearly, fewer than 400 return from the field with claims. Other sources report REC averages less than 100 claims per million modules. This exceptionally low failure rate stems from rigorous testing protocols that subject panels to multiple cycle accelerated tests beyond standard requirements.
REC products hold certifications for ISO 9001, ISO 14001, ISO 45001, and RoHS compliance. The company’s test lab is certified by VDE to TDAP standards, ensuring measurement accuracy and calibration precision at every testing stage.
HJT Technology and Innovation
REC’s Alpha series employs Heterojunction Cell Technology (HJT), combining crystalline silicon with amorphous silicon layers for superior energy conversion. Manufacturing HJT cells requires only 6 production steps compared to 11-14 steps for TOPCon technology. This simpler process reduces microcrack risk and energy consumption.
The low temperature production process for HJT cells operates at just 200°C, minimizing thermal stress and energy use. HJT cells feature a temperature coefficient of -0.24% per °C, enabling higher energy output even as temperatures rise.
REC guarantees at least 92% power output at year 25 for Alpha HJT products. In contrast, most TOPCon panels on the market offer 0.4% degradation per year, delivering only 89.X% power at year 25.
Comparison with Chinese-Made Panels
A 12-month study by Germany’s Fraunhofer Institute found REC modules performed 4.8% more efficient than panels from a leading Chinese manufacturer. REC also outperformed a European competitor’s modules by 1%. The anti-reflective treatment applied to all REC module glass since 2007 contributes to this performance advantage, allowing more sunlight to penetrate solar cells for conversion to electricity.
What Buyers Should Know About REC Panel Quality
Product Warranty and Performance Guarantees
REC backs their panels with warranty terms that reflect manufacturing confidence. All current REC panels include a 20-year product warranty covering defects in materials and workmanship. However, buyers working with REC Certified Solar Professional installers receive an extended 25-year product warranty. For the most part, installers offering REC panels are certified, so you’ll likely receive the full quarter-century coverage.
The ProTrust Warranty package adds labor coverage for systems under 25kW, lasting the full 25 years when installed by certified professionals. This protects you from out-of-pocket costs if panels require servicing.
Performance guarantees vary by product line but remain industry-leading. REC Alpha panels maintain 98% of nameplate power in year one, then degrade by a maximum of 0.25% annually, guaranteeing 92% output after 25 years. TwinPeak panels allow 0.5% annual degradation, delivering 86% minimum output at year 25[102]. Identically rated competitors typically offer 0.5-0.7% degradation rates, meaning REC Alpha panels produce 4-12% more energy over their lifetime.
Efficiency Ratings and Real-World Performance
REC panel efficiency ranges from 19.1% to 22.3% depending on model, with all current series exceeding the 20% threshold considered high-efficiency.
In reality, nameplate ratings tell only part of the story. Independent testing at REC’s Singapore facility showed actual yields exceeding PVsyst software predictions by over 5%. European installations demonstrated performance ratios 1.8-8.0% above projections. A Fraunhofer Institute study found REC modules achieved an 87.9% performance ratio, outperforming Chinese panels by 4.8% and European competitors by 1%.
Temperature coefficients matter significantly in hot climates. REC Alpha Pure-RX panels feature a -0.24%/°C coefficient, compared to typical panels at -0.34% to -0.40%. At 45°C, REC panels maintain 95.2% of rated power while standard panels drop to 93%.
Customer Reviews and Reliability Data
REC’s warranty claim rate stands at approximately 52 claims per million panels, translating to roughly 1 in 14,000 probability. Out of 4 million panels manufactured annually, fewer than 400 return with claims.
Customer satisfaction reflects this reliability. Analysis of over 1,100 reviews shows an average 4.9 out of 5 stars. In SolarQuotes Installer Choice Awards, REC ranked first in 2023 and second in 2025. The Alpha Pure 410-watt panel scored 100 out of 100 on EnergySage based on performance, warranty, durability, and manufacturing.
Buyers report production exceeding estimates, with panels generating throughout severe weather including tropical cyclones. Long-term owners note panels performing “beyond expectations” after 8 years of operation.
