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. ## Product images ![Trina Solar TSM-500NEG18R.28 — original front and rear view of the range](https://batterado.com/wp-content/themes/wodatherm/assets/images/solar-projects/trina-neg18r28-original.png) ![Batterado — TRINA-TSM-500NEG18R.28](https://batterado.com/wp-content/uploads/2026/11/trina-neg18r28-original.png) ## Downloads [Trina Solar NEG18R.28 — datasheet 2024 C](https://batterado.com/wp-content/themes/wodatherm/assets/documents/solar-projects/trina-neg18r28-datasheet-2024c.pdf) ## AI search description 500 Wp from one module for home, workshop and business rooftops.
