Automated Weather Station
Surechem is Malaysia's leading system integrator for Automatic Weather Stations (AWS) and Solar PV Monitoring Systems. We specialize in designing, supplying, and commissioning meteorological stations that meet the strict IEC 61724-1 Class A standards required for Large Scale Solar (LSS) farms, the Corporate Green Power Programme (CGPP), and the newly introduced Corporate Renewable Energy Supply Scheme (CRESS).
Unlike general suppliers, Surechem provides full turnkey solutions—from sensor selection (EKO Instruments, Campbell Scientific) to SCADA integration and TNB/SEDA compliance checks.
Solar Farm Weather Stations (LSS, CRESS & C&I)
For Solar PV developers and EPCs, accurate weather data is critical for Performance Ratio (PR) calculation, Yield Assessment, and Grid Interconnection. Our systems are fully compliant with TNB Technical Connection Guidelines, Malaysian Standard (MS) 1760, and the specific data requirements for Third Party Access (TPA) under the CRESS framework.
-
Class A Irradiance Monitoring: We utilize Secondary Standard (Class A) Pyranometers (such as the EKO MS-80SH) to ensure the highest accuracy for Global Horizontal Irradiance (GHI) and Plane of Array (POA) measurements—essential for the "Bilateral Energy Supply Contract" billing verification in CRESS projects.
-
Module Temperature: High-precision RTD sensors (Pt100/Pt1000) for back-of-module temperature tracking.
-
SCADA Integration: Seamless data transmission via Modbus TCP/IP or RTU to your Plant Process Computer (PPC), Data Aggregators, and the Single Buyer interface.
-
Proven Track Record & Future Ready: Trusted partner for major projects including LSS3 Sg. Petani (110MW), LSS4 Kerian (100MW) & LSS5 Sg. Petani (50MW). We are fully equipped to meet the strict local content and technical mandates for the newly awarded LSS5 projects and the upcoming LSS6 tenders, alongside supporting CRESS Renewable Energy Developers (RED).
Scientific & Environmental Monitoring
We build rugged, standalone AWS solutions for solar resource assessment, government agencies, agriculture (smart farming), and environmental research. Our stations are designed to withstand Malaysia's tropical climate—high humidity, frequent lightning, and heavy rainfall.
-
Solar Resource Assessment (SRA): We deploy autonomous, solar-powered stations to capture long-term "bankable" irradiance data, essential for securing financing and accurate yield forecasting for new developments.
-
Parameters Monitored: Global Horizontal Irradiance (GHI), Plane of Array (POA), Wind Speed/Direction, Rainfall (Precipitation), Barometric Pressure, Relative Humidity, Ambient Air Temperature, Back of Module Temperature & Soiling.
-
Data Logging: Utilizes Campbell Scientific data loggers (CR1000Xe, CR310, CR350) to ensure reliable data storage and seamless integration with existing PLC and SCADA architectures, including support for Huawei, Sungrow, and other leading solar farm platforms.
Our Strategic Partners & Technology
We are the Authorized Distributor and Preferred Integrator for the world’s most respected sensor manufacturers:
| Brand | Role / Specialization |
| EKO Instruments (Japan) | Class A Pyranometers (MS-80SH, MS-80S, MS-80). The industry leader for "Domeless" technology, offering faster response times and lower maintenance—ideal for ensuring "Firm Output" accuracy in LSS & CRESS projects. |
| Campbell Scientific (USA) | Data Loggers. The global standard for solar monitoring, offering programmable logic for complex SCADA requirements. |
| Gill Instruments (UK) | Compact Weather Station (GMX600). Features a built-in ultrasonic anemometer for maintenance-free Wind Speed & Direction, plus integrated sensors for Temperature, Humidity, Barometric Pressure, and Precipitation—eliminating the mechanical failure points of traditional cup anemometers. |
Why Choose Surechem?
-
Regulatory Compliance: We ensure every station meets the Grid Code for Peninsular Malaysia, which is mandatory for all LSS and CRESS participants connecting to the grid.
-
Local Technical Support: Our in-house engineering team handles the programming, wiring, and troubleshooting locally in Kuala Lumpur.
-
Calibration Services: We ensure your sensors (Pyranometers, Anemometers) remain within calibration validity as required by Operation & Maintenance (O&M) contracts.
Frequently Asked Questions (FAQ)
Q: Does Surechem weather stations comply with LSS5 and CRESS requirements?
A: Yes. We design our stations to strictly meet the IEC 61724-1 Class A standard, which is mandatory for all Large Scale Solar (LSS) projects and Renewable Energy Developers (RED) participating in the Corporate Renewable Energy Supply Scheme (CRESS).
Q: What is the advantage of EKO MS-80 pyranometers in Malaysia?
A: The EKO MS-80SH is a Class A "domeless" pyranometer. In Malaysia's tropical climate, this design prevents dew and dust accumulation better than traditional glass-dome sensors, ensuring higher data accuracy with less cleaning.
Q: Can you integrate with my existing SCADA system?
A: Yes. Our systems use industry-standard protocols like Modbus TCP/IP, Modbus RTU, and DNP3, ensuring compatibility with major SCADA platforms used in solar farms.
