Hyundai Solar Panels: Shingled-Cell & Corrosion-Resistant | Wholesale EU

Rebor B.V. is an EU wholesale distributor of Hyundai Energy Solutions (HD Hyundai Energy Solutions Co., Ltd.). Our range includes a selection of Full Black modules based on two fundamentally different cell technologies: G12 PERC Shingled for residential installations where shade tolerance and aesthetics are priorities, and N-Type HJT (Heterojunction) for projects where maximum efficiency, minimal degradation and a long warranty period are decisive. Both technology lines have been tested for salt-mist and ammonia resistance, making them suitable for installations in coastal areas and agricultural environments. View the current models below for the exact power class and datasheet for each model.

Two cell technologies: G12 PERC Shingled and N-Type HJT

The Hyundai modules in our range represent two technologically different product lines. The terms are not interchangeable, and each technology has its own advantages and disadvantages for specific applications.

G12 PERC Shingled: HiE Series (Full Black)

Shingled refers to a cell layout in which cells overlap like roof tiles and are bonded using electrically conductive adhesive (ECA) instead of conventional soldered connections. This eliminates solder joints as potential weak points, reduces internal resistance and maximises the active cell area. The underlying cell chemistry is PERC (Passivated Emitter and Rear Cell), which is a P-Type technology. Because of the overlapping cell structure, the contact lines on the front are largely covered by the cell above, resulting in a completely black front surface without visible busbars.

In practical terms, this provides improved shade tolerance through the parallel block configuration of the Shingled structure, Anti-LID/PID protection and an operating current that is compatible with most commonly used hybrid inverters. The efficiency of the HiE range is in the upper segment for PERC-based technology. Consult the datasheet of the current model for the exact efficiency and electrical parameters.

N-Type HJT (Heterojunction): HiT Series (Full Black dual glass)

HJT (Heterojunction Technology) combines a crystalline N-Type silicon core with thin layers of amorphous silicon on both sides. This results in superior electron flow, no LID (Light Induced Degradation) or PID (Potential Induced Degradation), and an exceptionally low temperature coefficient. The HiT range therefore performs better than PERC or conventional TOPCon modules at higher roof temperatures. The dual-glass construction enables bifacial light capture and provides increased mechanical protection.

In practical terms, the HiT Series offers the highest module efficiency of the two Hyundai lines, the lowest annual degradation and the longest warranty period. The high operating current of the HiT range requires a modern inverter that supports high input currents. Check this before installation. Consult the datasheet of the current model for the exact electrical parameters.

Shingled ≠ HJT ≠ PERC: Shingled describes a cell layout with overlapping cells. HJT and PERC describe cell technologies. The HiE range combines PERC cell technology with a Shingled cell layout. The HiT range uses HJT cell technology without a Shingled layout. These are two fundamentally different technologies with different efficiency levels, warranty structures and inverter compatibility requirements.

Warranty and power degradation

Hyundai Energy Solutions applies a linear performance-warranty structure to both product lines. The guaranteed remaining output decreases by no more than a fixed maximum percentage each year, providing a clear minimum performance level throughout the service life of the installation.

HiE Series: G12 PERC Shingled

  • Long-term linear product and performance warranty
  • High guaranteed remaining output after the first year
  • Anti-LID/PID protection reduces the risk of voltage-induced degradation
  • Consult the product page or datasheet of the current model for the exact warranty period and degradation curve

HiT Series: N-Type HJT

  • Longest warranty period of the two Hyundai product lines in our range
  • Very low annual degradation after the first year, characteristic of the N-Type HJT architecture
  • No LID or PID due to N-Type HJT, resulting in structurally lower degradation than P-Type technologies
  • Consult the product page or datasheet of the current model for the exact warranty period, remaining-output percentages and degradation curve

Solar panel and inverter compatibility: operating current and MPPT range

When designing a PV system with Hyundai solar panels, two electrical parameters are critical for selecting the inverter: the open-circuit voltage (Voc) and the maximum-power operating current (Impp).

The HiE range (G12 PERC Shingled) has an operating current that is compatible with most commonly used hybrid inverters. When designing a string, calculate the Voc at the lowest expected ambient temperature and compare it with the inverter’s maximum permitted input voltage.

The HiT range (N-Type HJT) has a high operating current. Older string inverters and entry-level models may limit this current. This current clipping can lead to structural power losses. We recommend using modern high-current inverters. View our range of Solis inverters and GoodWe inverters. When using microinverters, verify that the selected model supports the input current of the HiT range.

Consult the datasheet of the current model for the exact Voc, Isc, Vmpp and Impp values. For project-specific system guidance, use our battery calculator or contact our technical support team.

⚠️ Important, HiT Series N-Type HJT: The high operating current of the HiT range exceeds the maximum input current of many standard inverters. Check the inverter specifications before purchase and installation.

Environmental resistance: coastal areas, ammonia and mechanical loads

Both Hyundai product lines have been tested for salt-mist resistance and ammonia resistance. This makes them suitable for installations in coastal areas and agricultural environments with elevated ammonia concentrations, such as locations near livestock buildings. Salt-mist testing validates the corrosion resistance of the frame, junction box and connectors under prolonged exposure to a saline coastal climate.

The HiT range is certified in accordance with IEC 61215 and IEC 61730, the international baseline standards for the mechanical and electrical safety of PV modules. The dual-glass construction provides increased mechanical protection and improved resistance to microcracks. Consult the datasheet of the current model for the complete certification list and mechanical-load ratings.

Diagnostic protocol: power loss in Shingled and HJT solar panels

Both Hyundai product lines feature Anti-PID protection and are therefore less susceptible to potential-induced degradation. Other causes can nevertheless lead to unexpected power losses. The following protocol can support the diagnostic process.

  1. Check the inverter data. Compare the daily energy yield in kWh of the affected string with an appropriate reference period. A consistently lower yield during specific parts of the day may indicate a permanent source of shading or a fault in that string.
  2. Check for current clipping in the HiT range. If the inverter limits the high input current of the HiT range, the string will consistently operate below its potential rated power. Check the inverter logs for signs of current limitation.
  3. Inspect the ECA connections in the HiE range. In Shingled modules, the cells are connected using electrically conductive adhesive. Mechanical damage caused by incorrect installation or extreme thermal cycling may affect these connections. Visually inspect the module for cracks or delamination.
  4. Measure the open-circuit voltage (Voc) of each string. A significantly lower Voc than the calculated theoretical value may indicate a defective bypass diode or damaged solar panel.
  5. Inspect the junction box. Visually check for moisture ingress or corrosion. This is particularly relevant for coastal installations, despite the module’s tested salt-mist resistance.
Important note: A single case of power loss does not establish the existence of a structural product defect. Power losses frequently have installation-related or environmental causes. If in doubt, engage a qualified installer to perform a complete system inspection.

Frequently asked questions about Hyundai solar panels

What is the difference between the Hyundai HiE and HiT ranges?

The HiE range uses G12 PERC Shingled technology. The cells overlap like roof tiles and are joined using electrically conductive adhesive instead of conventional soldered connections. This provides improved shade tolerance through parallel block configuration, a completely black surface without visible busbars and an operating current that is compatible with most commonly used inverters. The HiT range uses N-Type HJT (Heterojunction) technology. It combines a crystalline silicon core with thin layers of amorphous silicon. This results in higher module efficiency, an exceptionally low temperature coefficient, no LID/PID and the longest warranty period of the two product lines. The high operating current of the HiT range requires a modern inverter that supports high input currents. View the current models above for the exact specifications.

Are Hyundai solar panels suitable for coastal areas?

Yes. Both Hyundai product lines, the HiE Series with G12 PERC Shingled technology and the HiT Series with N-Type HJT technology, have been tested for salt-mist resistance and ammonia resistance. This makes them suitable for installations in coastal areas and agricultural environments. Salt-mist testing validates the corrosion resistance of the frame, junction box and connectors under prolonged exposure to a saline coastal climate.

What are the advantages of Shingled cell technology compared with conventional PERC?

In conventional PERC modules, cells are positioned next to each other and connected using visible solder ribbons or busbars. In a Shingled layout, the cells overlap like roof tiles and are connected using electrically conductive adhesive (ECA). This eliminates solder joints as potential weak points, reduces internal resistance and maximises the active cell area. The parallel block configuration of the Shingled structure also means that partial shading of one block has less effect on the other blocks than in a conventional series connection. The result is improved shade tolerance and a completely black front surface without visible busbars.

What warranty structure does Hyundai Energy Solutions offer?

Hyundai Energy Solutions applies a linear performance-warranty structure to both product lines. The guaranteed remaining output may decrease by no more than a fixed maximum percentage each year. The HiT range with N-Type HJT technology offers the longest warranty period of the two product lines and very low annual degradation, characteristic of the N-Type HJT architecture. The HiE range with G12 PERC Shingled technology also offers a long-term linear warranty. Consult the relevant product page or datasheet for the exact warranty period, guaranteed remaining-output percentages and degradation curve.

Which inverters are compatible with Hyundai solar panels?

The HiE range (G12 PERC Shingled) has a standard operating current and is compatible with most commonly used hybrid inverters, including models from Solis and GoodWe. The HiT range (N-Type HJT) has a high operating current. Before installation, verify that the inverter supports this input current. We recommend modern high-current inverters. For project-specific system guidance, use our battery calculator or contact our technical support team.

Where can I find the exact specifications of a Hyundai model?
