Trina Solar Vertex S+ TSM-500NEG18R.28 — 500 Wp photovoltaic module, N-type i-TOPCon, dual glass

Description

Technical specifications

An individual module for your solar installation

This offer covers one specified 500 Wp photovoltaic module. Combine individual modules into a generating array and pair them with a suitable inverter or charge controller. Select energy storage in kWh separately through a battery and its matching charging system.

N-type i-TOPCon and 22.5 % efficiency

TSM-500NEG18R.28 uses 108 monocrystalline cells and produces 500 Wp at 22.5 % module efficiency under standard test conditions. Positive power tolerance is 0 to +5 W. Rated power is measured at 1000 W/m² irradiance and 25 °C cell temperature; actual generation planning accounts for location and operating conditions.

Electrical data for string design

Maximum-power voltage is 33.3 V and current 15.03 A. Open-circuit voltage is 40.1 V and short-circuit current 15.86 A. Series-connected module voltages add together; select string length so the entire array meets the actual device MPPT range and maximum voltage at local temperatures.

Performance under NOCT conditions

For this 500 Wp variant the datasheet lists 382 W at NOCT, with 31.5 V MPP voltage and 12.11 A MPP current. Defined comparison conditions are 800 W/m² irradiance,20 °C ambient temperature and 1 m/s wind. These values help assess module behaviour alongside its STC peak rating.

Dual glass and black frame

Front and rear glass are each 1.6 mm thick and heat-strengthened; the front adds an antireflective coating and high transmission. A 30 mm black anodised aluminium frame surrounds the module. The glass-glass construction supports long-term rooftop photovoltaic applications.

Temperature and climatic conditions

Module operating temperature is −40 to +85 °C. Temperature coefficients are −0.29 %/°C for power,−0.24 %/°C for open-circuit voltage and +0.04 %/°C for short-circuit current. Design accounts for cold-weather voltage and hot-cell output. Tested loads are 5400 Pa for snow and 2400 Pa for wind; mounting is designed for the actual building.

Connections, cables and bypass diodes

The junction box is rated IP 68 and contains three bypass diodes. The manufacturer specifies 4 mm² PV cable, standard 1300/1300 mm lengths and a 280/350 mm special-order option. Connector options are TS 4 and TS 4 Plus, with MC 4 EVO 2 available by special order. Choose a specific matching connector variant for the system.

Equipment to pair with the module

Use a suitable PV input on an inverter, microinverter or MPPT charge controller. Match voltage range and maximum voltage, operating and short-circuit currents, array power and connector type. For battery charging, route solar power through a charge controller or hybrid inverter designed for that battery.

Array power and generated energy

Two modules provide 1 kWp nominal array power and ten provide 5 kWp. Wp describes peak array rating; energy generated in kWh depends on sunlight, orientation, tilt, temperature and system losses. Select inverter AC output for the actual loads and battery capacity for operation after sunset.

Long-term performance specified by Trina Solar

The datasheet states a 25-year product workmanship warranty and 30-year power warranty subject to manufacturer terms. Its power curve specifies maximum 1 % first-year degradation and 0.4 % annually in years 2–30, reaching 87.4 % at year 30. Applicable warranty terms relate to the actual product and region.

Choose module quantity and the supply configuration

Specify required power, available area and mounting method, inverter or controller and any storage. An individual-module offer lets you select the actual quantity. Use the Batterado product enquiry to confirm supply, the connector variant and matching equipment.
