At a typical module operating temperature of 65°C, this translates to approximately 4–5% higher retained power output compared to a PERC module with identical STC nameplate rating. - **Bifaciality factor >90% from HJT symmetry** - The naturally symmetrical heterojunction structure enables a bifaciality factor above 90%, versus 70–75% typical for bifacial PERC. In agrivoltaic installations over light-colored ground surfaces (soil, sand, light mulch), this realistically boosts energy yield by several percent at no additional BoS cost. - **30-year linear power warranty** - Huasun provides a 30-year linear power output guarantee alongside a 15-year product warranty. The linear degradation profile improves revenue predictability in project-finance models and extends the LCOE calculation horizon compared to products with shorter power warranties. - **BNEF Tier-1 status and TÜV Rheinland certification** - Huasun achieved BNEF Tier-1 manufacturer status (confirmed Q1 2025), ensuring bankability for projects requiring external financing or insurance. Modules in the agrivoltaics line hold TÜV Rheinland certification, confirming compliance with safety standards for specialized dual-use applications. - **Purpose-built semi-transparent agri-PV design** - The HSN-210R-B64 series is specifically engineered for agrivoltaic systems: approximately 33% photosynthetically active radiation (PAR) transmission enables crop growth beneath the modules — a capability unavailable in standard bifacial panels that block virtually all light. Huasun developed this technology in partnership with French agri-PV operator Feedgy. ## Cons - **Efficiency 14.3–14.8% below peer comparables** - Against comparable transparent and bifacial modules in a similar power range — Solar-Fabrik Mono S4 Halfcut Transparency Project (15.11%) and AE Solar Terra E CMD-72BD (15.39%) — the HSN-210R-B64 series trails by 2–8% in module efficiency. This requires proportionally more mounting area to achieve the same target system capacity. - **15-year product warranty vs. 25-year industry standard** - The Tier-1 module industry standard for product (materials and workmanship) warranty is 25 years. The HSN-210R-B64 series offers only 15 years, which may be a barrier for bank-financed or fund-financed projects that require full warranty coverage aligned with the loan tenor (typically 20–25 years). ## About this series The Huasun HSN-210R-B64 series is designed to prioritize stable yield in challenging operating conditions and maximize diffuse light utilization. These modules, based on n-type cells using HJT technology, perform exceptionally well at high temperatures and maintain their parameters over time. Another key feature is the **bifacial design** - the module can operate not only "frontally," but also harness reflections from the ground, which genuinely increases energy production in properly designed systems. In practice, the HSN-210R-B64 addresses common issues such as yield drops during hot periods and space limitations on the mounting surface - especially in light roof projects, carports, or agricultural solutions. The application of **HJT technology** and **n-type cells** helps minimize degradation and improves yield predictability. This is an excellent choice for investors seeking **high energy yield from diffuse light** and looking to build installations with a better annual production balance. ## Notable figures - Module efficiency of 14.5% is 6.1pp below average for \*\*HJT 0-400W\*\* panels (median: 20.6%) - Power density of 145.1 W/m² is 61.3 W/m² below \*\*HJT 0-400W\*\* median (206.4 W/m²) - needs more roof space - At -0.24%/°C, hot weather performance is typical for \*\*HJT 0-400W\*\* panels - Bifacial design (90% factor) captures reflected light - adds 4-14% yield on ground-mount or white roof - In the top 99% for efficiency among all HJT panels ## Questions ### What is the temperature coefficient of the Huasun HSN-210R-B64, and does it matter in summer? The temperature coefficient of Pmax is just -0.24%/°C, one of the best figures available for HJT modules. In practice, the HSN-210R-B64 loses far less power on hot days compared to typical PERC cells (around -0.35%/°C). For carport or open-air agricultural installations exposed to intense sunlight, this difference translates into a measurable gain in annual energy yield. ### Is the Huasun HSN-210R-B64 suitable for agrivoltaic installations on farmland? Yes, that is exactly what this series is designed for. The module features 32% light transmittance, allowing crops growing beneath the panels to receive sufficient solar radiation. At 1762×1134 mm and 21.5 kg, it fits lightweight structures above farmland. It is a ready-made solution for farmers who want to combine energy production with agricultural activity on the same plot. ### What does the bifacial design offer in the HSN-210R-B64 series, and when does it actually pay off? The bifacial design means the rear side of the module also generates power from light reflected off the ground. In agrivoltaic setups over bright soil, snow, or light-colored gravel, the bifacial gain can range from a few to over ten percent annually. The effect is greatest with open-rack structures, good airflow, and a bright reflective surface directly beneath the panels. ### What warranty does the Huasun HSN-210R-B64 come with? Huasun provides a 15-year product warranty covering defects and workmanship, plus a 30-year power output warranty. Under the power warranty, the manufacturer guarantees the module will retain at least 90.3% of its rated power after 30 years of operation. These are among the best warranty terms available for HJT panels and reflect the low degradation rates characteristic of n-type cells. ### Why is the efficiency of the HSN-210R-B64 lower than other Huasun HJT modules? The HSN-210R-B64 is a semi-transparent module with 32% light transmittance — a portion of incoming sunlight is deliberately passed through rather than converted to electricity. This is why efficiency sits at 14.3–14.8%, well below opaque HJT modules (22–24%). The trade-off is intentional: the priority is simultaneous power generation and adequate light delivery to plants below, not maximizing panel efficiency alone. ### Can Huasun HSN-210R-B64 modules be installed on carports and lightweight structures? Yes. The 1762×1134×30 mm dimensions and 21.5 kg weight make these modules well suited for lightweight structures above vehicles (carports) and crops. HJT n-type cell technology and low annual degradation ensure installations on open-air structures maintain solid output over many years. Proper tilt is recommended to maximize bifacial gain from ground reflectance. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/agrivoltaics-module-hsn-210r-b64dsn-285-295-en-20250814-778921a81da1.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-300MH-72](https://comparepv.com/panel/ja-solar-ns-300mh-72) | 300 W | Lighter, +8.8 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | Lighter, +8.8 pp, -5 yr warranty | | [Heckert Solar ZEUS 1.2 FullBlack 280W](https://comparepv.com/panel/heckert-solar-zeus-1-2-fullblack-280w) | 280 W | Hotter, lighter, +8.8 pp | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Lighter, +8.6 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Lighter, +8.6 pp, -5 yr warranty | | [Gamko New Energy GKA182M285W](https://comparepv.com/panel/gamko-new-energy-gka182m285w) | 285 W | Lighter, +8.5 pp | | [Gamko New Energy GKA182M240W](https://comparepv.com/panel/gamko-new-energy-gka182m240w) | 240 W | -50 W, lighter, +8.5 pp | | [Gamko New Energy GKA182M260W](https://comparepv.com/panel/gamko-new-energy-gka182m260w) | 260 W | -30 W, lighter, +8.5 pp | | [Gamko New Energy GKA182M270W](https://comparepv.com/panel/gamko-new-energy-gka182m270w) | 270 W | -20 W, lighter, +8.5 pp | | [Huasun HSN-210R-B64DSN285](https://comparepv.com/panel/huasun-hsn-210r-b64dsn285) | 285 W | Very close match | | [Huasun HSN-210R-B64DSN295](https://comparepv.com/panel/huasun-hsn-210r-b64dsn295) | 295 W | +0.3 pp | | [Huasun HSN-210R-S96DSC410](https://comparepv.com/panel/huasun-hsn-210r-s96dsc410) | 410 W | +120 W, heavier, +6.0 pp | | [Huasun HSN-210R-B96DSN435](https://comparepv.com/panel/huasun-hsn-210r-b96dsn435) | 435 W | +145 W, +7.3 pp | | [Huasun HSN-210R-B96DS440](https://comparepv.com/panel/huasun-hsn-210r-b96ds440) | 440 W | +150 W, +7.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +220 W, heavier, +10.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +205 W, hotter, +10.3 pp | --- Source: https://comparepv.com/panel/huasun-hsn-210r-b64dsn290 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.
