Light for its output, weak in heat
The Gamko New Energy GKA182M144 series consists of modules with a large active area, designed to maximize energy yield in a limited mounting space. The use of monocrystalline PERC cells and a half-cut (semi-cut) design helps minimize losses and improves panel performance even with partial shading - a common occurrence in Poland due to chimneys, skylights, or trees. The MBB multi-busbar design also enhances current collection and supports stable operation in everyday conditions.
The GKA182M144 is suitable for both high-end residential installations and larger commercial and industrial projects, where rapid power generation and predictable energy production are crucial. Thanks to its refined design, the module performs well even in less sunny conditions, and its resistance to degradation and long-term performance sets it apart from many standard panels in this segment.

Top 1% of the PERC 550-600 W segment, against a median of 52.7. Ranked 725th in the whole database.

The 144 half-cut cell layout reduces resistive losses by approximately 75% compared to full-cell configurations, while the multi-busbar (MBB) architecture improves current collection efficiency. Bifacial light absorption delivers a real-world yield gain of 8-15% on rooftop installations and 20-30% on ground-mounted systems with high-albedo surfaces, translating into higher annual energy yield without increasing the installation footprint.
The maximum module efficiency of 21.28% matches that of the IBC Solar 182M Half Cell 540-550W and sits only 0.02 percentage points below the Goldi Solar GS10-B144-TF and S-Energy SL65-72BGJ (both at 21.3%). The series therefore sacrifices nothing in power density relative to its direct competitors in this cell format.
Gamko offers a 30-year linear power output warranty - exceeding the 25-year standard common among most mainstream Chinese manufacturers. The extended warranty horizon directly improves bankability for externally financed projects and supports stronger IRR figures in 25+ year financial models.
Availability across 10 variants spanning 530-550 Wp allows precise module selection to match a fixed number of strings without exceeding inverter input limits - particularly valuable for expanding existing installations or projects subject to strict grid connection power caps.
The modules carry IEC 61215 (performance and durability testing) and IEC 61730 (electrical safety) certifications, and according to ENF Solar data also hold CE, ISO 9001, and ISO 14001 marks. This full certification package enables installation and subsidy eligibility under national support programs (Mój Prąd, KPO) without risk of rejection during audits.
In 2025-2026, the premium segment for the 182 mm format is broadly migrating to TOPCon (N-type) technology, which exhibits approximately 0.3-0.5% lower annual LID degradation rate and a better temperature coefficient (approx. -0.30%/°C vs. -0.35%/°C for PERC). Over the 30-year warranty horizon, this translates into measurably lower cumulative energy yield compared to manufacturers that have already transitioned to N-type in this power class.
Gamko New Energy (1.2 GW of manufacturing capacity in 2023) does not appear on Bloomberg NEF's Tier-1 Module Manufacturer lists. For installations financed through bank loans or institutional leasing, this may create difficulties in obtaining lender module approval and result in less favorable residual value insurance terms compared to Tier-1 manufacturers.
A 12-year workmanship warranty is the norm for Chinese mid-tier suppliers, but falls noticeably short of the 15-25 years offered by European and Korean manufacturers in a comparable price bracket (e.g., IBC Solar at 15 years). In longer-term commercial installations, this gap directly affects the cost of potential module replacements once the manufacturer's product warranty has expired.
- Efficiency of 21.3% matches the PERC 550-600W median
- At 212.8 W/m² power density, roof space requirements are typical for PERC 550-600W panels
- At -0.36%/°C, hot weather performance is typical for PERC 550-600W panels
- Weight of 25.0 kg (5.8 kg below PERC 550-600W median of 30.8 kg) allows easier transport and roof mounting
- Ranked #8863 out of 14129 panels for efficiency in the database
