At a cell operating temperature of 45°C, HJT loses ~1.3% less power than PERC, translating to a measurable gain in annual energy yield even in temperate climates. - **HJT bifaciality up to 95%** - HJT modules achieve a bifaciality factor of 80-95%, while standard bifacial PERC panels top out at ~70%. On high-albedo surfaces — mulch film, gravel, snow, concrete — the rear-side generation advantage is directly reflected in higher system yield, making this well-suited for agrivoltaic ground mounts and carports. - **Double glass + 30-year linear power warranty** - The glass-glass construction reduces annual degradation to below 0.4% (vs. 0.55-0.7% typical for backsheet laminates) and eliminates moisture ingress and UV-induced EVA discoloration. The 30-year power warranty exceeds the 25-year standard offered by peer comparables such as Heckert Solar NEMO 2.0. - **0BB technology — improved low-irradiance output** - Eliminating conventional busbars in the 0BB layout shortens current paths, lowers resistive losses, and improves photon collection at low incidence angles and under overcast skies — a meaningful advantage in Central European locations where diffuse radiation constitutes a significant share of annual GHI. - **BNEF Tier-1 bankable manufacturer** - Huasun (founded 2020) achieved BNEF Tier-1 status in Q1 2023, becoming the first dedicated HJT specialist to reach that ranking in record time. The designation confirms that six commercial banks have provided non-recourse financing for projects using Huasun modules, satisfying standard bankability requirements for utility-scale and commercial PV projects. ## Cons - **Module efficiency 14.6-15.1% — niche range** - Peer comparables in the same power bracket (up to 335 Wp) reach 19.9% (Heckert NEMO 2.0) and 20.16% (SunLink LUXMAX), meaning the HSN-210R-B72 requires approximately 33% more surface area per kWp installed. The low efficiency is intentional — wider cell spacing enables light transmission to crops below — but effectively limits this series to agrivoltaic and carport applications, ruling it out for space-constrained rooftop or standard ground-mount projects. - **Limited manufacturer track record** - Huasun was founded in 2020 and has only ~5 years of operating history. Issuing a 30-year power warranty without a long-term financial track record introduces counterparty risk for institutional investors and lenders, notwithstanding the BNEF Tier-1 bankability status. ## About this series The Huasun HSN-210R-B72 series was designed for installations where both energy production and light transmittance are critical - especially in agrivoltaic projects. These modules are based on **HJT** technology, which combines the benefits of monocrystalline silicon and thin-film layers. This allows the panels to operate stably in high temperatures and better utilize diffuse light, typical of many locations in Poland. The key feature of this series is the **bifacial construction**, which enables energy recovery from the rear side as well, such as from a light-colored substrate, film, or surface in agricultural and industrial facilities. The use of **dual glass** enhances resistance to moisture, UV exposure, and micro-cracking, ensuring a longer, predictable lifespan. Additionally, solutions like **0BB** shorten the current flow path within the cell, reducing losses and supporting performance under lower irradiance. This makes it an excellent choice for PV farms, carports, and canopy structures over crops, where competitive panels often require compromises between energy and light transmission. ## Notable figures - At 15.1% efficiency, this panel is 5.5pp below the \*\*HJT 0-400W\*\* median of 20.6% - Power density of 150.7 W/m² is 55.7 W/m² below \*\*HJT 0-400W\*\* median (206.4 W/m²) - needs more roof space - Temperature coefficient of -0.24%/°C matches the \*\*HJT 0-400W\*\* median - Weight of 26.9 kg is 5.4 kg above \*\*HJT 0-400W\*\* median (21.5 kg) - verify structural support - 90% bifaciality enables rear-side power generation, boosting yield by 4-14% on reflective surfaces ## Questions ### Are Huasun HSN-210R-B72 panels suitable for agrivoltaic installations? Yes, the HSN-210R-B72 series is purpose-built for agrivoltaics. The semi-transparent module design transmits a portion of solar radiation, allowing crops to grow underneath without excessive shading. At the same time, the bifacial HJT construction ensures efficient energy production from both the front and rear sides, capturing light reflected from the soil or light-colored ground cover. ### How does HJT technology in the Huasun HSN-210R-B72 series compare to standard PERC panels? HJT cells combine a crystalline silicon absorber layer with thin amorphous silicon layers, resulting in a lower temperature coefficient — typically around -0.26%/°C versus -0.35%/°C for PERC. The HSN-210R-B72 therefore loses less power on hot days and handles diffuse irradiance better, which translates to a measurably higher annual energy yield in climates with frequent cloud cover, without requiring additional modules. ### What warranty does the Huasun HSN-210R-B72 series carry? The HSN-210R-B72 series comes with a 15-year product warranty and a 30-year power output warranty. The modules are guaranteed to maintain manufacturer-specified performance levels for three full decades of operation. For the agri-PV segment, these are strong warranty terms, and Huasun's Tier 1 manufacturer status backs the credibility of those commitments. ### What is the 0BB technology in Huasun HSN-210R-B72 panels and why does it matter? 0BB (zero busbar) eliminates traditional metal busbars from the cell surface. Current is collected via micro-wires or specialized film, which shortens the electron path and reduces resistive losses. In practice, the module performs better under low-irradiance conditions common during transitional months, and removing busbars improves the uniformity of light transmittance — a critical feature in agrivoltaic applications. ### Is the HSN-210R-B72 dual-glass series a good fit for carports and agricultural canopy structures? Yes. The dual-glass construction makes these modules highly resistant to moisture, UV radiation, and microcracks — the main failure modes for panels installed on open carports and farm canopies. The bifacial design captures additional energy from light reflected off concrete or asphalt surfaces below, and dual glass eliminates the EVA encapsulant degradation risk associated with single-glass outdoor installations. ### What is the maximum power output of the Huasun HSN-210R-B72 and is it sufficient for commercial PV farm projects? The HSN-210R-B72 series has a maximum peak power of 335 Wp. For a semi-transparent agrivoltaic module that must balance power generation with crop light transmittance, this is a strong result. Higher wattages in this product class typically come at the cost of reduced light transmission, so 335 Wp in HJT technology represents a favorable trade-off for both agri-PV farms and industrial installations with aesthetic or dual-use requirements. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/agrivoltaics-module-hsn-210r-b72dsn-325-335-en-20250814-e1e91ac472d0.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-300MH-72](https://comparepv.com/panel/ja-solar-ns-300mh-72) | 300 W | Lighter, +8.2 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | Lighter, +8.2 pp, -5 yr warranty | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Lighter, +8.0 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Lighter, +8.0 pp, -5 yr warranty | | [Gamko New Energy GKA182M285W](https://comparepv.com/panel/gamko-new-energy-gka182m285w) | 285 W | -50 W, 16 kg lighter, +7.9 pp | | [Gamko New Energy GKA182M300W](https://comparepv.com/panel/gamko-new-energy-gka182m300w) | 300 W | -35 W, lighter, +7.9 pp | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | -15 W, lighter, +7.9 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +7.9 pp | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | +25 W, lighter, +7.9 pp | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | +45 W, lighter, +7.9 pp | | [Huasun HSN-210R-B72DSN325](https://comparepv.com/panel/huasun-hsn-210r-b72dsn325) | 325 W | -10 W, -0.5 pp | | [Huasun HSN-210R-B72DSN330](https://comparepv.com/panel/huasun-hsn-210r-b72dsn330) | 330 W | Very close match | | [Huasun RS490S8R-108GANT](https://comparepv.com/panel/huasun-rs490s8r-108gant) | 490 W | +155 W, hotter, +7.0 pp | | [Huasun HSN-210R-B108DSN495](https://comparepv.com/panel/huasun-hsn-210r-b108dsn495) | 495 W | +160 W, +7.2 pp | | [Huasun HSN-210R-B108DSN500](https://comparepv.com/panel/huasun-hsn-210r-b108dsn500) | 500 W | +165 W, +7.4 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +225 W, hotter, +9.7 pp | --- Source: https://comparepv.com/panel/huasun-hsn-210r-b72dsn335 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.
