Need help?Do you have a question about the Trina Solar Crystalline Series and is the answer not in the manual?
This document outlines the installation, handling, use, and maintenance procedures for Trina Solar crystalline photovoltaic (PV) modules, specifically the TSM-PC06A, TSM-DE171H(II), and TSM-DC082H.08(II) models, for both IEC and UL versions. It emphasizes safety precautions, proper installation methods, electrical configuration, and ongoing care to ensure optimal performance and longevity of the solar system.
Trina Solar crystalline PV modules are designed to convert sunlight into DC electricity. These modules are intended for use in photovoltaic systems, where they are typically connected in series to increase voltage or in parallel to increase current, ultimately feeding into an inverter to convert DC electricity to AC for grid integration or direct use. The modules are engineered to operate automatically with minimal day-to-day supervision, generating electricity whenever exposed to light. They are equipped with bypass diodes within the junction box to minimize module heating and current losses, enhancing efficiency and reliability. The design also accounts for various environmental conditions, including resistance to ammonia fumes and suitability for humid or sandy environments, ensuring broad applicability.
The modules offer flexible mounting options, allowing for installation in either landscape or portrait orientation. For optimal energy output, installation at an optimized tilt angle, typically corresponding to the project site's latitude and facing the equator, is recommended. The document details two primary mounting methods: using corrosion-proof M8 bolts through designated mounting holes on the module's rear frame, or employing specially designed module clamps. Both methods require specific hardware, torque settings, and clearances to ensure structural integrity and compliance with safety standards.
When mounting with bolts, the module frames feature 4-φ9*14mm mounting holes, strategically placed for optimal load handling. Stainless steel fixings are strongly recommended for longevity, with M8 bolts tightened to a torque of 16-20 N.m (140-180 lbf.in). Flat stainless steel washers of minimum 1.5mm thickness and 20-24mm outer diameter are required for all parts in contact with the frame.
For clamp mounting, Trina Solar modules are compatible with various clamps from different manufacturers, provided they meet specific criteria: a minimum length of 40mm (1.57in), thickness of 3mm (0.12in), and made from aluminum alloy 6003 or 6005. The clamp must overlap the module frame by 7-10mm (0.28-0.39in) and should not contact the front glass or deform the frame. A minimum of four clamps per module is required, placed on the long sides for portrait orientation or short sides for landscape orientation, with additional clamps potentially needed based on local wind and snow loads. The applied torque for M8 bolts in clamp systems is also 16-20 N.m (140-180 lbf.in).
A third mounting method is described for single-axis tracking systems, where the module is fixed on the axis by bolting the long frame. This method utilizes 4-φ7*10mm (0.28*0.39in) mounting holes, M6 bolts, two flat washers, a spring washer, and a nut, with a recommended torque of 16 N.m (140 lbf.in). All contact parts should use flat stainless steel washers of minimum 1.5mm thickness and 16-20mm outer diameter.
Regardless of the mounting method, a minimum clearance of at least 115mm (4.5in) is recommended between the module frame and the mounting surface (wall or roof) to prevent affecting UL Listing or fire class ratings. A minimum distance of 10mm (0.4in) between modules is also specified. Crucially, the mounting method must not obstruct the module drainage holes, and panels should not be subjected to static loads exceeding permissible limits or excessive forces from thermal expansion of support structures.
Electrical connections are made using stranded copper cables with a cross-sectional area of 4mm² (0.006in²), rated for 1500V DC, 90°C, and UV resistance. Modules are connected in series by plugging the positive plug of one module into the negative socket of the next, and in parallel by connecting positive terminals together. Proper polarity must be verified before making parallel connections to prevent irreparable damage to the product. The system's maximum voltage must not exceed 1500V DC, and the open circuit voltage of the array string must be calculated at the lowest expected ambient temperature to ensure compatibility with the inverter and other electrical devices. For parallel connections, it is suggested that every series SPV module string be fused to protect against overcurrent. The modules are supplied with two 90°C sunlight-resistant output cables, 12AWG in size, terminated with plug-and-play connectors, suitable for direct sunlight exposure.
The document emphasizes that a well-designed solar system requires minimal maintenance, but regular checks can significantly improve performance and reliability. Annual maintenance by trained personnel, wearing appropriate safety gear (rubber gloves and boots rated for 1500V DC), is recommended.
Key maintenance tasks include:
The document also provides guidance on troubleshooting and reporting technical issues. Users are advised that the solar modules do not contain user-serviceable parts. In case of malfunctions, the installer should be contacted immediately. For damaged modules (broken glass or scratched back sheet), specific safety precautions must be followed during replacement, including isolating the impacted array string, disconnecting connectors with the proper tool, and verifying the open circuit voltage of the array string before reconnecting.
Grounding is a critical maintenance aspect. All module frames and mounting racks must be properly grounded according to the National Electrical Code. This involves bonding metallic structural members together with a suitable grounding conductor (copper, copper alloy, or other acceptable material) and connecting to an earth ground electrode. Trina Solar modules can also be grounded using third-party listed grounding devices, installed according to the manufacturer's instructions. Electrical contact is made by penetrating the anodized coating of the aluminum frame and tightening the mounting screw (with a star washer) to 25 lbf.in. Grounding wire size (6 to 12 AWG solid bare copper) should be selected and installed under the wire binding bolt, tightened to 45 lbf.in. Specific grounding bolt methods from Tyco and ERICO are detailed, emphasizing proper torque and wire type.
