The advantage of up to +2.4 percentage points translates into measurable area savings — on a 10 kWp rooftop system, that means approximately 0.5–1 fewer modules to achieve the same installed capacity. - **Low Temperature Coefficient Pmax: −0.29%/°C** - N-type TOPCon technology delivers a significantly more favorable temperature coefficient than typical PERC modules (−0.34 to −0.36%/°C). At a summer module operating temperature of 65°C, power losses are reduced by approximately 1.3–1.75 percentage points, with a measurable positive impact on summer energy yield in the Polish climate. - **30-Year Power Output Warranty, Retention ≥87.4%** - The power warranty terms are on par with leading Tier-1 brands — Jinko Solar likewise guarantees 30 years at 87.4% retention for its bifacial module series. For investors, this enables a credible LCOE calculation over the full system lifetime. - **Independent pvmagazine Rating: 5★ (91/100)** - The HY SOLAR N-type TOPCon series received a "Very Good" rating in a pvmagazine test conducted by Gsola laboratory on 5 randomly sampled modules from mass production. Independent third-party validation is rare among manufacturers outside the BNEF Tier-1 list and represents a meaningful risk-mitigation argument for quality-conscious investors. ## Cons - **No BNEF Tier-1 Status (Q1 2026)** - HY SOLAR does not appear on the BNEF Tier-1 list as of Q1 2026 data. In practice, this creates a barrier to project finance for commercial installations and utility-scale PV plants above 50 kWp, where financial institutions routinely require modules from Tier-1-listed manufacturers as a condition for granting loans or leasing agreements. - **Product Warranty of 15 Years vs. the 25-Year Industry Standard** - Leading Tier-1 manufacturers — Jinko Solar, Trina Solar, and JA Solar — standardly offer a 25-year product warranty (materials and workmanship) on their new TOPCon series as of 2025–2026. HY SOLAR's coverage is limited to 15 years, which represents a real gap in risk protection for projects with long financing horizons of 20 years or more. ## About this series The HY SOLAR HY-NT10/54GDF series is a double-sided N-type TOPCon module that effectively increases energy yield not only from the front, but also from reflected light from the ground. This makes it ideal for locations where maximum power generation from a limited area is crucial, such as rooftops of homes and businesses, carports, and ground-mounted installations. The use of **SMBB and half-cut cell technology** improves performance under partial shading and reduces losses due to internal resistance, resulting in more stable generation under typical, variable conditions in Poland. The modules also stand out due to **high PID resistance**, which is important for long-term operation, and **good performance at high temperatures**, which helps maintain efficiency on hot days. The entire system is complemented by **a long, multi-year warranty**, which is important for investors who expect predictability and security in their projects. Compared to many competing PERC panels, this series offers a more modern cell architecture and better performance in low-light conditions. ## Notable figures - At 22.3% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - Power density of 222.7 W/m² matches the \*\*TOPCon 400-450W\*\* median - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - Weight of 24.5 kg is 2.5 kg above \*\*TOPCon 400-450W\*\* median (22.0 kg) - verify structural support - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### What warranty does the HY SOLAR HY-NT10/54GDF series come with? The HY-NT10/54GDF series carries a 15-year product warranty covering material and workmanship defects, and a 30-year power output warranty guaranteeing at least 87.4% of rated power after 30 years of operation. This is one of the longer power warranties available in this product class, providing reliable return-on-investment predictability over three full decades. ### What does bifacial mean for the HY-NT10/54GDF and how much extra energy can it generate? A bifacial panel harvests light from both the front side and reflected light from the ground or surroundings. The HY-NT10/54GDF has a bifaciality factor of 80–85%, which can deliver 5–15% additional energy depending on surface albedo — light gravel, white membranes, and concrete improve reflection. On pitched roofs the gain is lower than in ground-mounted systems. ### Do HY-NT10/54GDF panels handle partial shading from a chimney or tree well? Yes. SMBB and half-cut cell technology mean that shading one section of the module does not proportionally reduce output for the entire panel. Each half-cell string operates independently, significantly limiting losses from typical roof-level shading caused by chimneys, antennas, or tree branches — compared to conventional PERC modules. ### How does TOPCon technology in the HY-NT10/54GDF series differ from older PERC technology? TOPCon (Tunnel Oxide Passivated Contact) is a newer N-type cell architecture offering higher efficiency (up to 23.3% for this series), better performance under low irradiance, and a lower temperature coefficient of −0.29 %/°C versus a typical −0.35 %/°C for PERC. This means smaller power losses on hot days and higher energy yield under real-world conditions — overcast mornings and variable spring and autumn weather. ### What are the dimensions and weight of the HY-NT10/54GDF panel — will it fit on a residential roof? The module measures 1762 × 1134 × 30 mm and weighs 24.5 kg. A standard pitched residential roof typically accommodates 15 to 25 modules, yielding a system in the 7–12 kWp range — suitable for most single-family homes. Dimensions are close to common PERC panels, so no custom mounting hardware is required. ### How does the HY-NT10/54GDF series perform during hot summer days? With a low temperature coefficient of Pmax at −0.29 %/°C, the HY-NT10/54GDF loses less power on hot days than typical PERC modules rated at −0.35 %/°C. At a cell temperature of 65 °C, the module retains approximately 88.7% of rated power. This translates into higher yields in July and August, when rooftop surface temperatures in Poland can exceed 70 °C. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/hy-solar-pv-modules-product-handbook-en-v-2505-1-4cf2fe6a1a5c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, lighter, +2.5 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +45 W, lighter, +2.2 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +45 W, lighter, +2.2 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +40 W, lighter, +2.0 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +40 W, lighter, +2.0 pp | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +40 W, lighter, +2.0 pp | | [HY SOLAR HY-NT10/54GDF-450](https://comparepv.com/panel/hy-solar-hy-nt10-54gdf-450) | 450 W | Very close match | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +65 W, cooler, +2.7 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +60 W, cooler, +2.4 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +55 W, cooler, +2.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +55 W, lighter, +2.2 pp | --- Source: https://comparepv.com/panel/hy-solar-hy-nt10-54gdf-445w 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.
