Middle of its segment, weak in heat
The Rarlon PV Tech Polycrystalline Photovoltaic Module series, available in 60-cell and 72-cell configurations, are designed for stable operation in typical operating conditions in Poland, from rooftop installations to larger ground-mounted systems. The use of polycrystalline cells is a practical choice for investors seeking a proven technology with predictable performance and a good cost-effectiveness ratio in both renovation and budget-conscious projects.
A key feature of this series is positive power tolerance, which makes it easier to maintain the intended performance of the entire string without unexpected issues after installation. The modules feature a high-sealing junction box and bypass diodes, which improve resistance to partial shading and reduce the risk of losses due to uneven sunlight exposure. The construction, based on tempered glass, supports durability in windy, rainy, and temperature-fluctuating conditions.
This is a good option for installers and investors who want to rely on a simple, compatible, and easy-to-maintain series of panels in standard formats.

Signals from the data
Residential and commercial.
Hot climates, tight roof space and roofs where every square metre has to count.
Bottom 2% of the 160-360 W band, against a median of -0.360. Ranked 13,879th in the whole database.
Bottom 18% of the 160-360 W band, against a median of 17.70%.
Bottom 19% of the 160-360 W band, against a median of 176.4.
Modules feature positive power tolerance, meaning no risk of receiving a panel below the rated Wp value. This simplifies precise string power balancing without unexpected losses after installation.
Bypass diodes reduce performance losses under partial shading, while a high-rated junction box improves resistance to moisture and contamination in more demanding mounting environments.
The series has been in production since 2014, meaning years of field performance history and well-understood degradation behavior - a strong asset for investors who prioritize predictability over novel technologies.
The use of tempered glass supports mechanical resistance to snow and wind loads, relevant for Poland's typical climate with significant seasonal variability.
Efficiency up to 17.21% is comparable to similar poly-Si modules on the market, e.g. TPL P-60 (17.1%) or Gintech GIN P6F-60 (17%), placing the series in the typical range for this technology.
Maximum efficiency of 17.21% clearly lags behind modules based on newer cell technologies - e.g. Techwise Solar Micro Sun Series reaches 21.12% at the same 280 Wp power rating, a roughly 4 percentage-point gap that means lower energy yield from the same roof area.
Rarlon PV Tech (Ningbo Rarlon Photovoltaic Technology) does not appear on the current BloombergNEF Tier 1 list, unlike segment leaders such as JA Solar, Trina Solar, or Jinko Solar. This can complicate project financing where banks require Tier 1 components.
Polycrystalline cells inherently have a lower efficiency ceiling than mono-Si PERC or TOPCon cells now dominant in the market, meaning lower installed power for the same roof area compared to newer mono-based solutions.
- Efficiency of 16.0% is 5.8pp below the database median (21.8%)
- At 159.8 W/m², this panel generates 58.3 W/m² less per unit area than database median (218.1 W/m²)
- At -0.47%/°C, loses 0.17pp more power per degree than database median (-0.30%/°C)
- Weight of 17.0 kg (9.5 kg below database median of 26.5 kg) allows easier transport and roof mounting
- In the top 97% for efficiency among all N-type panels
