Qcells Solar Panels Ireland: Q.TRON & Q.PEAK Duo Review
Qcells (Hanwha Qcells, formerly styled Q CELLS) is a Korean-owned, German-engineered brand with a strong reputation for build quality. Here's our independent review of Qcells solar panels for Ireland, covering the premium Q.TRON N-type range, the budget Q.PEAK Duo line, and how Q CELLS compares to Jinko and LONGi.
Quick Answer
Qcells (Q CELLS) is a premium, German-engineered solar brand owned by Korea's Hanwha group. The flagship Q.TRON range uses N-type TOPCon cells reaching around 22.5% efficiency, up to ~440W, with around 90.6% output guaranteed at year 25. The budget Q.PEAK Duo (P-type Q.ANTUM) range runs around 19.5–21.1% efficiency. The whole current range carries a 25-year product warranty, making Q CELLS a strong choice for Irish homeowners who value engineering reputation.
Who Are Qcells (Q CELLS)?
Qcells is a Korean-owned, German-engineered solar manufacturer. The brand traces its roots to Germany and is now part of the Hanwha group of South Korea, where it is often styled Hanwha Qcells. It built its name on German engineering standards and is best known for its Q.ANTUM cell technology and zero-gap cell connection.
The current line-up splits into two tiers. The premium Q.TRON range uses N-type TOPCon cells for higher efficiency and slower degradation, while the budget Q.PEAK Duo range uses the older P-type Q.ANTUM platform. Both carry a 25-year product warranty across the current range, which is a key reason Q CELLS appeals to Irish homeowners who prioritise engineering reputation over chasing the very highest headline efficiency.

The Qcells Panel Range
Q CELLS splits its residential offering into a premium N-type range and a budget P-type range. For new Irish installs in 2026, the Q.TRON range is the one to ask your installer about.
Q.TRON (premium)
N-type TOPCon cells reaching around 22.5% efficiency and up to ~440W. Around 90.6% output guaranteed at year 25 with degradation of roughly 0.33% per year. The flagship choice.
Q.PEAK Duo (budget)
P-type Q.ANTUM cells with around 19.5–21.1% efficiency and roughly 86% output guaranteed at year 25. A more affordable option where budget matters more than peak output.
Q.ANTUM platform
The cell technology underpinning both ranges, paired with zero-gap cell connection. This is the engineering heritage Q CELLS is best known for.
Qcells Q.TRON Specifications
| Specification | Value |
|---|---|
| Range | Q.TRON (premium) |
| Wattage | Up to ~440W |
| Cell Technology | N-type TOPCon (Q.ANTUM) |
| Efficiency | Up to ~22.5% |
| Temperature Coefficient | ~−0.29 to −0.30%/°C |
| Product Warranty | 25 years |
| Performance Warranty | ~90.6% output at year 25 |
| Degradation Rate | ~0.33% per year |
| Connection | Zero-gap cell technology |
| Budget alternative | Q.PEAK Duo (P-type, ~19.5–21.1%) |
| Engineering | German-engineered, Hanwha-owned |
The Q.TRON range is the panel most Irish installers will quote for new premium systems. Its N-type TOPCon cells deliver a low temperature coefficient of around −0.29 to −0.30%/°C and slow degradation of roughly 0.33% per year — both useful in Ireland's mild, overcast climate. The budget Q.PEAK Duo range remains a cheaper option but trails on both efficiency and end-of-life output.
Q CELLS vs Jinko and LONGi: Which Is Better?
| Feature | Qcells Q.TRON | Jinko Tiger Neo | LONGi Hi-MO 6 |
|---|---|---|---|
| Wattage | Up to ~440W | 440W | 415–435W |
| Cell Technology | N-type TOPCon | N-type TOPCon | HPBC (back-contact) |
| Efficiency | Up to ~22.5% | 22.3% | Up to 22.8% |
| Temperature Coefficient | ~−0.29 to −0.30%/°C | −0.29%/°C | −0.29%/°C |
| Product Warranty | 25 years | 25 years | 25 years |
| Performance Warranty | ~90.6% at year 25 | 30 years (87.4%) | 25 years (88.85%) |
| Degradation | ~0.33%/year | 0.4%/year | 0.4%/year |
| Reputation | German engineering | Largest by output | Largest by shipments |
Verdict: All three are strong N-type-led choices. Q.TRON's headline draw is its German engineering reputation plus an impressive ~90.6% guaranteed output at year 25 and low ~0.33%/year degradation. LONGi's Hi-MO 6 edges ahead on peak efficiency (up to 22.8%) with a back-contact full-black look, while Jinko offers the longest performance warranty (30 years) and the broadest installer availability in Ireland. For homeowners who value build reputation and long-term output retention, Q CELLS is an excellent pick; for the lowest price and widest availability, Jinko typically wins.
