In agrivoltaic deployments where modules operate under full irradiance for extended hours during summer, this advantage translates into measurably higher energy yield on hot days. - **Bifacial dual-glass with zero-busbar cells** - The bifacial design (bifaciality factor >90%) combined with a frameless glass-glass laminate captures reflected irradiance from the ground, mulch, or vegetation. In agrivoltaic installations with light-colored substrates (mulch, snow, pale soil), rear-side gain can reach 5-15% above equivalent monofacial modules at the same STC rating. - **32% transmittance optimized for PAR** - The module transmits 32% of visible light, targeting the photosynthetically active radiation (PAR) band. Per Huasun's technical documentation, the proprietary light-conversion film technology achieves higher PAR distribution beneath the array than competing agri-PV modules that require ≥39% bulk transparency to reach equivalent crop-level irradiance. - **30-year linear power output warranty** - Huasun provides a 30-year linear performance warranty - on par with leading Tier-1 manufacturers such as LONGi and Jinko. For agrivoltaic projects typically financed over 25-30-year debt terms, this warranty directly supports LCOE modeling and lender bankability assessments. - **BNEF Tier-1 status (Q1 2025)** - Huasun has held BNEF Tier-1 bankable manufacturer status since Q1 2023 and maintained it through Q1 2025. As the world's largest HJT module manufacturer (20 GW installed capacity, deliveries to 80+ countries), it meets the supply chain reliability and after-sales support criteria required by project finance institutions. ## Cons - **Module efficiency below peer group** - Efficiency of 14.3-14.8% is the lowest among all peer comparables: Hiwatt Solar HW-P360H reaches 17.8%, AE Solar Terra E CMD-72BD - 15.39%, Solar-Fabrik Mono S4 Halfcut - 15.11%. The reduced power density (W/m²) is an inherent consequence of the module's transparency design; however, in agrivoltaic installations with constrained roof or land area, this results in approximately 15-20% lower total energy output per unit area compared to full-cell modules. - **Product warranty limited to 15 years** - The product (materials & workmanship) warranty covers only 15 years, while leading Tier-1 manufacturers (LONGi, Jinko, JA Solar) standardly offer 25-year product warranties, and some HJT specialists provide up to 30 years. For agrivoltaic projects with a 25-30-year operational horizon, the shorter product warranty increases the risk of post-year-15 O&M costs. - **Limited manufacturer operating history** - Huasun Energy was founded in July 2020, giving it roughly 5 years of operating history while issuing 30-year power warranties. The lack of a long-term financial track record remains a residual risk for project finance banks and warranty insurers evaluating the sustainability of warranty obligations - despite the company's BNEF Tier-1 designation in Q1 2025. ## About this series Huasun 64 Half-cell Agrivoltaics HJT Module is an innovative solution designed with the synergy of agriculture and modern solar energy in mind.

Agrivoltaics refers to the simultaneous use of the same land for solar power generation and agricultural production. The Huasun 64 Half-cell HJT modules feature increased glass transparency so that crops grown beneath the array receive adequate sunlight. This is especially attractive where farmland prices are rising, as dual land use can significantly increase revenue per hectare while generating clean energy. ### What warranty comes with the Huasun 64 Half-cell Agrivoltaics HJT modules? Huasun provides a 15-year product warranty and a 30-year linear power warranty. Over those three decades, modules retain more than 88% of their rated power output. For agrivoltaic installations, which often face harsher environmental conditions than rooftop systems, these warranty terms are highly competitive and provide strong long-term investment security. ### Does HJT technology in the Huasun 64 Half-cell series perform well during hot summers? Yes, this is one of HJT's key advantages. The temperature coefficient of Huasun's HJT modules is approximately -0.24%/°C, compared to around -0.35%/°C for standard PERC modules. In practice, when module temperature exceeds 60°C on a hot summer day, the Huasun 64 Half-cell series loses significantly less power than conventional alternatives, resulting in higher annual energy yield - particularly important for open-field agrivoltaic installations with no shading from buildings. ### What does bifacial dual-glass construction mean, and how does it affect the performance of these modules? Bifacial dual-glass means the module generates electricity from both the front and rear sides, with both surfaces protected by tempered glass instead of a plastic backsheet. In agrivoltaic setups, the rear side captures light reflected from soil, grass, or mulch, boosting total energy output by up to 15%. The dual-glass design also delivers superior resistance to moisture ingress, ammonia corrosion, and mechanical stress - all critical factors in agricultural environments. ### What is the maximum power output of the Huasun 64 Half-cell Agrivoltaics HJT module, and is it sufficient for a large solar farm? The module's maximum power output is 295 Wp under STC conditions. The 64 half-cut cell format is purpose-built for agrivoltaic applications where controlled light transmission and crop shading management take priority over peak power density. Large-scale farms combine multiple modules into strings connected to string or central inverters. Standard 72-cell modules offer higher per-unit wattage but cannot provide the calibrated light transparency that this series delivers. ### Are the Huasun 64 Half-cell HJT modules rated for heavy snow loads and high winds typical of open agricultural sites? Yes. The dual tempered-glass construction is rated for snow loads up to 5400 Pa and wind loads up to 2400 Pa. For ground-mounted installations on open farmland where there are no natural windbreaks, this structural rating is critical. The glass also provides certified resistance to ammonia corrosion, making these modules well-suited for sites near livestock buildings. ## 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 | | [Heckert Solar ZEUS 3.2 285WP FullBlack](https://comparepv.com/panel/heckert-solar-zeus-3-2-285wp-fullblack) | 285 W | Hotter, lighter, +8.6 pp | | [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 | | [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-b64-dsn290 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.
