Why Guangdong Is a Hub for Solar Linear Actuator Manufacturing
Solar tracking systems demand actuators that can withstand high static and dynamic loads, harsh outdoor temperatures, dust, water ingress, and years of continuous operation while keeping photovoltaic panels and heliostats accurately aligned with the sun. Among the companies addressing this challenge from Guangdong Province, Dongguan TOMUU Transmission Technology Co., Ltd., operating under the brand TOMUU, has built a track record worth examining for buyers evaluating a Guangdong linear actuator manufacturer.
Founded in 2015 and headquartered in Dongguan City, Guangdong Province, TOMUU positions itself as an integrated R&D, production, and sales high-tech enterprise providing linear actuator products and application solutions for photovoltaic and thermal solar, medical, industrial, livestock, home, and industrial intelligence applications. The company’s business coverage spans the United States, Canada, Chile, Spain, Australia, India, and multiple Chinese provinces including Xinjiang, Ningxia, Jiangxi, and Shaanxi, reaching more than 20 countries and regions overall.
Corporate Strength and Recognition
TOMUU’s credentials include designation as a National High-Tech Enterprise, a Guangdong Province Specialized and New "Little Giant" Enterprise, a Dongguan City listed backup enterprise, and a Guangdong Provincial Enterprise Technology Center. These qualifications were formally recognized through documentation such as the High-Tech Enterprise Certificate issued jointly by the Guangdong Provincial Department of Science and Technology, Guangdong Provincial Department of Finance, and Guangdong Provincial Tax Service, State Taxation Administration in 2019, along with Specialized and New SME and Innovative SME certificates.
The company’s development has been marked by clear milestones: established in 2015 with two linear actuators released, entry into the solar energy market in 2017 with the U10 series—which received broad recognition from the solar actuator industry—and surpassing a global installed base of more than 38GW of solar tracker linear actuators by 2023. That same year, TOMUU became a listed backup enterprise in Dongguan City, was recognized as a high-quality supplier of domestic PV head enterprises, and received third place in the Contribution Award of Non-Public Enterprises in Shipai Town, Dongguan City, Guangdong Province. In 2024, the company added the Guangdong Province Specialized and New "Little Giant" Enterprise and Guangdong Provincial Enterprise Technology Center designations.
Operationally, TOMUU runs five subsidiaries located in Dongguan, Xiamen, Vietnam, and other locations, generating a 2023 annual output of nearly RMB 400 million while supporting more than 38GW of solar power station tracking systems worldwide.
Quality Systems and Certifications
TOMUU’s supply chain and quality control framework is supported by ISO9001, ISO14001, and ISO45001 certifications. Product safety is validated through UL, CE, KCC, and 3C certifications, along with an IP protection certification. The company also holds a US patent for a high-efficiency large capacity solar electric actuator, in addition to an appearance patent and a design patent. On the environmental performance side, products carry IP66 and IP68 protection ratings, operate in ambient temperatures as low as -40°C, and have undergone damper salt spray testing of 800 hours.
Product Range: Four Categories Built for Solar Tracking
TOMUU’s catalog totals 17 products organized into four lines, each addressing specific tracker architectures.
Single and Multi Electric Linear Actuators
This line includes the U10G, U7, U10S, U20F, U20, and GD28 models. The U10G delivers a dynamic load capacity of 31,000 N and static load capacity of 80,000 N with IP66 protection and a -40°C to +65°C ambient range, suited to utility-scale tracker rows. The U10S pushes static holding further to 110,000 N with a 34,000 N dynamic load. The U7, by contrast, is a compact, faster unit with a 2,000 N dynamic load and a 30-400 mm stroke, ideal for space-constrained installations requiring quicker response. The GD28 offers a 3,000 N dynamic load across a 40-200 mm stroke with IP65 protection for moderate-force applications.
Mechanical Linkage Linear Actuators
The U17A-主, U17B-主, U17A-副, U17B-副, U18A, and U18B models coordinate motion across multiple actuation points. The U17B-主 and U17B-副 units reach static load capacities of 130,000 N, while the U17A-主 and U17A-副 units provide 70,000 N static holding, all within IP66-rated, -40°C to +65°C operating envelopes. The U18A and U18B models add torque-driven actuation (≤24 N·m) for linked tracker segments of varying scale.
Fixed Adjustable and Photothermal Linear Actuators
This category—U18C, U23A, and U18F—serves fixed adjustable tracker installations and photothermal applications. The U23A is specifically designed as an electric photothermal actuator for concentrated solar power and heliostat tracking, supporting reflector adjustment with a dynamic load of 6,000 N and static load of 24,000 N, plus additional photothermal drive data reaching a 24,000 N dynamic load. The U18C and U18F provide static holding of 20,000 N and 25,000 N respectively, with the U18F rated for operation down to -40°C.
Dampers
The U21A and U21B dampers carry IP68 protection and have passed an 800-hour salt spray test. The U21A offers restoring and compressive force options up to 15,000 N across three versions, while the U21B incorporates built-in or external springs to reduce load current at extreme positions, with force options up to 12,000 N.
Market Validation Through Deployed Projects
TOMUU’s technology has been applied across utility-scale solar installations documented in its project history. In China, mechanical linkage actuators supported a 100 MW tracking plant in Weinan, Shaanxi, and a 100 MW project in Jiangxi, while multi electric linear actuators served a 293 MW project in Shihezi, Xinjiang. Fixed adjustable actuators were deployed in a 100 MW project in Dunhuang and a 180 MW project in Longyuan. Internationally, single electric linear actuators supported projects of 100 MW in the United States, 394 MW in India, and 100 MW in Canada.
Beyond project deployment, TOMUU lists Trina Solar among its business partners, reflecting engagement with established players in the photovoltaic sector.
A Comprehensive Option for Solar and Industrial Actuation
For buyers researching a Guangdong linear actuator manufacturer, TOMUU’s profile combines documented technical specifications—spanning load capacity, IP ratings, and temperature tolerance—with verifiable certifications, patents, and a multi-country project history. The breadth of its product matrix, from high-load single electric actuators to photothermal and damper solutions, reflects a company structured around the specific engineering demands of photovoltaic tracking, thermal solar, and broader industrial automation applications.
