Over a 30-year installation lifetime, this translates into several percentage points of genuinely higher cumulative energy yield. - **30-year power output warranty** - The manufacturer provides a 30-year linear power warranty — longer than the Talesun TM7G78M (BIPRO), which carries a standard 25-year term. For externally financed utility-scale PV projects, a longer warranty horizon directly reduces investment risk. - **Bifacial design + 132 half-cut cells** - The bifacial construction enables an additional 5–15% energy gain from ground-reflected irradiance (light gravel, white roofing membrane, snow), while the 132 half-cut cell layout reduces resistive losses and improves performance under partial shading compared to full-cell configurations. - **Wide range of wattage variants** - Seven variants spanning 605–635 Wp allow precise string sizing to match roof or field conditions without the need for power optimizers. This is a significant advantage when designing larger agricultural and commercial PV installations. ## Cons - **No BNEF Tier-1 bankable status** - HD Solar does not appear on the BNEF Tier-1 bankable manufacturers list (confirmed Q1 2026), unlike LONGi Solar, which is present among peer comparables. This limits the availability of non-recourse bank financing for large-scale utility PV projects and may reduce module acceptability for institutional investors requiring bankability verification. ## About this series The HD Solar HD-N-G12 132 half-cell series utilizes monocrystalline N-type TOPCon cells, designed to maximize energy yield under real-world operating conditions. The use of a **132 half-cell** arrangement minimizes losses due to microcracks and reduces the risk of power drops in partially shaded conditions - which is particularly important on roofs with skylights, chimneys, or installations near trees. The **bifacial** design further allows for the utilization of reflected light from the ground, improving production, especially on bright roofs and in PV farms. A key advantage of this series is its **stable performance at high temperatures**, which translates to more predictable results in the summer. The series is also complemented by a **long product warranty**, which supports investment security. HD-N-G12 132 half-cell is a good choice for companies, agriculture, and large ground-mounted installations where high power density, reliability, and lower system cost per watt are important. ## Notable figures - Efficiency of 22.6% matches the \*\*TOPCon 600-650W\*\* median - Power density of 225.8 W/m² matches the \*\*TOPCon 600-650W\*\* median - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 600-650W\*\* median - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - In the top 26% for efficiency among all TOPCon panels ## Questions ### What warranty does the HD Solar HD-N-G12 132 Half cells series come with? The HD-N-G12 132 Half cells series includes a 15-year product warranty and a 30-year power output warranty. The power warranty guarantees a minimum percentage of rated output after 30 years of operation, which is a critical factor when calculating ROI for commercial projects and utility-scale PV farms with a long investment horizon. ### Do the HD Solar HD-N-G12 132 Half cells handle partial shading well? Yes, the half-cut cell layout with 132 cells significantly reduces power losses under partial shading. Splitting each cell in half lowers the internal operating current, limiting the impact of shadows from chimneys, dormers, or nearby trees on the entire string. This makes the HD-N-G12 a practical choice for urban and agricultural rooftops where avoiding shading is difficult. ### What does bifacial mean for the HD Solar HD-N-G12 panels, and is it worth the extra cost? A bifacial module generates electricity from both the front side (direct irradiance) and the rear side (light reflected off the surface below). On light-colored rooftops, white membranes, or ground-mounted systems with high-albedo surfaces, bifacial gain can add several percentage points to annual yield. On standard clay rooftiles the effect is smaller but still measurable and contributes to a shorter payback period. ### What is the peak power of the HD Solar HD-N-G12 132 Half cells and what does it mean for system design? The maximum power output of the HD-N-G12 132 Half cells series reaches 635 Wp. The large-format G12 (210 mm) cells deliver high power density per square meter, reducing the total number of modules required and lowering overall BoS costs — including racking, cabling, and labor — per kilowatt-hour of energy produced. ### How does TOPCon technology affect HD-N-G12 panel performance during hot summer days? N-type TOPCon cells have a lower temperature coefficient than conventional PERC cells, meaning the percentage power drop per degree Celsius increase is reduced. In practice, HD-N-G12 modules retain more of their rated output during peak summer heat compared to standard p-type modules, delivering more predictable and consistent energy yield throughout the summer season. ### What types of installations are the HD Solar HD-N-G12 132 Half cells best suited for? The HD-N-G12 132 Half cells series is best suited for large commercial, agricultural, and ground-mounted utility-scale PV installations where high power density and low system cost per unit of energy yield are the top priorities. The combination of up to 635 Wp, TOPCon cell technology, and bifacial construction also makes them a strong fit for agrivoltaic projects and large industrial rooftops. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/hd-n-132-g12-half-cells-605-635wp-bifacial-double-glass-pv-m-82aecc99036b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +40 W, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -50 W, lighter, +2.2 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +2.2 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, lighter, +2.0 pp | | [Longi Solar LR8-66HVD-660M](https://comparepv.com/panel/longi-lr8-66hvd-660m) | 660 W | +50 W, cooler, +1.8 pp | | [HD Solar HD-N-G12-605](https://comparepv.com/panel/hd-solar-hd-n-g12-605) | 605 W | -0.2 pp | | [HD Solar HD-N-G12-615](https://comparepv.com/panel/hd-solar-hd-n-g12-615) | 615 W | Very close match | | [HD Solar HD-N-G12-620](https://comparepv.com/panel/hd-solar-hd-n-g12-620) | 620 W | +10 W, +0.4 pp | | [HD Solar HD-N-G12-625](https://comparepv.com/panel/hd-solar-hd-n-g12-625) | 625 W | +15 W, +0.5 pp | | [HD Solar HD-N-G12-630](https://comparepv.com/panel/hd-solar-hd-n-g12-630) | 630 W | +20 W, +0.7 pp | | [HD Solar HD-N-G12-635](https://comparepv.com/panel/hd-solar-hd-n-g12-635) | 635 W | +25 W, +0.9 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +70 W, lighter, +2.6 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +65 W, lighter, +2.4 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +90 W, cooler, +2.4 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +85 W, cooler, +2.3 pp | --- Source: https://comparepv.com/panel/hd-solar-hd-n-g12-610 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.
