The 1.78–5.02 percentage-point advantage translates into a measurably smaller installation footprint for the same peak power output. - **N-type TOPCon Cell Technology** - N-type TOPCon cells exhibit significantly lower light-induced degradation (LID) and a superior temperature coefficient compared to P-type PERC cells, which — given Poland's climatic conditions with large diurnal temperature swings — meaningfully increases annual energy yield. Bifacial TOPCon technology has been recognized as the premium standard in the residential and commercial module segment since 2023. - **Bifacial Design — Additional Yield from Reflected Irradiance** - The bifacial construction enables energy generation from both the front and rear faces of the module. At a typical TOPCon bifaciality factor of 70–85% and with a high-albedo surface (light-colored roofing, gravel, or snow), real-world energy yield can increase by 10–25% relative to a monofacial equivalent, making this series particularly attractive for ground-mounted systems and rooftop installations with light-colored surfaces. - **30-Year Power Output Warranty** - The manufacturer provides a 30-year linear power output warranty, placing it among the longest commitments in the segment — peer-comparable products such as the First Solar Series 6 Plus Bifacial and the Sunket SKT460~480M10-120D3 offer a standard 25–30-year warranty. The extended warranty horizon reduces investor financial risk and improves IRR metrics for projects financed under long-term models. - **Mechanical Ratings Suited to Polish Conditions** - The series carries certified resistance to snow load (5,400 Pa) and wind load (2,400 Pa), meeting the requirements for the majority of Polish climatic zones under standard PN-EN 1991-1-3. Additional PID resistance limits degradation in systems operating at high system voltages typical of 1,000 V DC string configurations. ## Cons - **12-Year Product Warranty — Below the Premium Benchmark** - The manufacturer offers only a 12-year product warranty (materials and workmanship), whereas leading Tier 1 manufacturers — LONGi, Trina Solar, and JA Solar — routinely provide 15 years. For investors planning installations with a 25–30-year service life, this represents a real risk of no warranty coverage during the final 13–18 years of operation. - **No BNEF Tier 1 Status — Limited Bankability** - Gamko New Energy does not appear on the BNEF Tier 1 lists (Q1 2025 / Q1 2026), which complicates or prevents securing third-party project financing (investment loans, leasing) for utility-scale PV projects where financial institutions require modules from bankable manufacturers. While this factor carries less weight for prosumer installations, it limits the potential for reselling the project to an institutional investor. ## About this series The Gamko New Energy GKA96N-PRO series is designed to maximize energy yield on a limited surface area - a solution that truly helps to "extract" more power from a roof or a tightly planned installation. The use of **N-type TOPCon** cells supports high efficiency and stable performance over a longer period, while the **multi busbar** design improves current collection and increases resistance to micro-cracks during installation and operation. In practice, this series also performs well in less sunny conditions - thanks to the optimized surface of the cells and anti-reflective coated ribbons, which results in more predictable yields on cloudy days. Another advantage is **PID resistance**, which is particularly important in demanding environments. For investors, **resistance to wind and snow loads** is also important, making it easier to select panels for Polish conditions. The GKA96N-PRO is suitable for residential, commercial, and projects where efficiency and reliability are paramount. ## Notable figures - Efficiency of 23.3% is 0.8pp above the \*\*TOPCon 450-500W\*\* median (22.5%) - Power density of 232.7 W/m² packs 7.5 W/m² more into the same footprint vs \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 450-500W\*\* median - 21.0 kg weight - 3.0 kg lighter than \*\*TOPCon 450-500W\*\* median (24.0 kg), reducing installation effort - In the top 9% for efficiency among all TOPCon panels ## Questions ### What warranty is provided for Gamko New Energy GKA96N-PRO panels? The GKA96N-PRO series comes with a 12-year product warranty covering material and workmanship defects, as well as a 30-year linear power output warranty. The latter means the manufacturer guarantees a specified minimum energy yield from the panel over three decades. This is the standard warranty level for N-type TOPCon cells, which exhibit lower annual degradation rates compared to older PERC technology. ### Is the Gamko GKA96N-PRO a bifacial panel, and what does that mean in practice? Yes, the GKA96N-PRO is a bifacial module. The front side absorbs direct solar irradiance, while the rear side captures light reflected from the ground surface (albedo). In installations over highly reflective surfaces — such as gravel-covered flat rooftops, light-colored facades, or ground covered with a white geomembrane — the rear-side power gain can reach several to over ten percent. On steep roofs with dark tiles, the bifacial effect is minimal. ### Will the GKA96N-PRO 480 W panels perform reliably in the Polish climate, with heavy snow and wind loads? Yes. The GKA96N-PRO series is certified for snow loads up to 5,400 Pa and wind loads up to 2,400 Pa, meeting Polish structural standards even in mountainous regions. The aluminum frame and tempered glass with an anti-reflective coating protect the cells against moisture and frost. It is always advisable, however, to verify the mounting design against the local snow and wind load zones applicable to the specific installation site. ### How does the N-type TOPCon technology in the GKA96N-PRO differ from conventional PERC cells? TOPCon (Tunnel Oxide Passivated Contact) cells are built on N-type silicon substrate, which contains fewer impurities and exhibits lower degradation over the entire service life of the module. Compared to PERC, they deliver higher module efficiency (up to approximately 23%), better performance at elevated temperatures, and greater resistance to PID (Potential-Induced Degradation). This translates into higher annual energy yields per square meter of rooftop without requiring a larger number of panels. ### Do Gamko GKA96N-PRO panels perform efficiently on overcast days? Yes, the GKA96N-PRO series is optimized for low-irradiance conditions. The anti-reflective coated glass increases the transmittance of diffuse light, while the multi-busbar technology shortens the current path and reduces internal resistive losses. The manufacturer confirms strong performance under diffuse irradiance — a significant advantage in Poland, where more than half of all days per year involve partial cloud cover. ### How many Gamko GKA96N-PRO 480 W panels do I need for a 10 kWp installation? At a peak power of 480 W per panel, a 10 kWp system requires approximately 21 modules (10,000 W ÷ 480 W ≈ 20.8, rounded up). The exact number depends on the selected power variant within the series range (460–480 W) and the string-inverter configuration. It is recommended to consult a certified installer who can determine the optimal panel count based on available roof area, orientation, shading analysis, and inverter capacity. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/pro-96n-182x210mm-solar-cells-26242b40715b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +30 W, cooler, +1.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +40 W, cooler, +1.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +25 W, cooler, +1.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +35 W, cooler, +1.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +35 W, cooler, +1.2 pp | | [Gamko New Energy GKA96N-PRO-460W](https://comparepv.com/panel/gamko-new-energy-gka96n-pro-460w) | 460 W | -0.2 pp | | [Gamko New Energy GKA96N-PRO-470W](https://comparepv.com/panel/gamko-new-energy-gka96n-pro-470w) | 470 W | +0.2 pp | | [Gamko New Energy GKA96N-PRO-475W](https://comparepv.com/panel/gamko-new-energy-gka96n-pro-475w) | 475 W | +10 W, +0.5 pp | | [Gamko New Energy GKA96N-PRO-480W](https://comparepv.com/panel/gamko-new-energy-gka96n-pro-480w) | 480 W | +15 W, +0.8 pp | --- Source: https://comparepv.com/panel/gamko-new-energy-gka96n-pro-465w Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
