In 1500V systems, the voltage differential between the frame and cells is significantly higher than in 1000V architectures, amplifying PID risk — TD-AN3's dual barrier directly addresses this, protecting long-term energy yield across the full asset lifetime. - **1500V DC system compatibility** - Certified 1500V system voltage allows designers to configure longer strings (more modules per MPPT input), reducing cabling runs, DC combiners, and junction boxes. BoS cost savings from 1500V architecture over 1000V are typically estimated at 5–10% of CAPEX, improving project LCOE. - **IEC 61701 salt mist level 6 certification** - Level 6 is the highest tier in the IEC 61701 salt mist corrosion standard. Combined with triple certification (IEC, TUV, UL), the series is a reliable choice for coastal, harbor, and industrial sites where corrosion-driven degradation is the primary portfolio risk factor. - **Floating PV deployment capability** - The moisture-blocking rear surface enables installation on water bodies. Floating PV sees growing demand due to the water-cooling effect — modules typically operate 5–15% more efficiently than ground-mount during summer peaks — while eliminating land-use conflicts. - **Manufacturer credibility: BNEF Tier-1, since 1965** - Hansol Technics held BNEF Tier-1 status (Q4 2024 / Q1 2025) at ~600 MW/year production capacity. Operating since 1965, the company's long operational history reduces orphaned-warranty risk over the 25-year linear power guarantee period — a key bankability parameter for project finance. ## Cons - **Discontinued series** - The TD-AN3 series is marked as discontinued. This limits the availability of replacement modules for mechanical failures, complicates system expansion with identical panels (string power mismatch), and may hamper post-warranty service once distributors exhaust their remaining inventory. - **Efficiency below current peer comparables** - The series peaks at 18.05% efficiency, while peer comparable Corab Encor reaches 19.27% (+1.22 pp) at the same 360 Wp max power, and Lina Energy LE MEPV reaches 18.44% (+0.39 pp). The gap versus Corab means TD-AN3 requires approximately 6–7% more rooftop or ground area to achieve the same installed capacity. - **Older-generation mono-crystalline cell technology** - Since 2024, TOPCon accounts for over 66% of global new PV module production capacity, delivering lower LID/LeTID and a better temperature coefficient (~–0.28%/°C) compared to conventional mono (~–0.37%/°C). TD-AN3 does not benefit from these advances, resulting in a measurable annual yield disadvantage at elevated operating temperatures. - **Monofacial construction — no bifacial gain** - The non-bifacial design (is\_bifacial: false) forfeits rear-side irradiance capture. Standard bifacial gain ranges from 5–30% depending on ground albedo — in ground-mount and floating PV applications where albedo is high (light water surface), the monofacial construction represents a quantifiable energy yield loss compared to newer bifacial series. ## About this series The Hansol TD-AN3 series consists of monocrystalline photovoltaic modules based on a 72-cell array, designed for installations requiring high reliability and long-term energy production stability. A key innovation of this series is the **Anti-PID technology** - implemented at both the cell and encapsulation levels - which effectively eliminates potential-induced degradation (PID), protecting the investment's profitability for decades. The modules are designed for operation in **1500V systems**, resulting in real cost savings on Balance of System (BoS) components and a reduced overall investment cost. Exceptional **mechanical durability**, certified by IEC, TUV, and UL, makes the TD-AN3 ideal for use in harsh climatic conditions, including heavy snowfall and strong winds. Optional compatibility with **floating PV systems** (thanks to the back side that prevents moisture penetration) opens up possibilities for mounting on reservoirs and water bodies. Certification for salt spray resistance (IEC 61701, level 6) makes these panels ideal for marine and industrial environments. The series is covered by a **25-year linear performance warranty**, making it a reliable choice for investors and developers seeking long-term, predictable returns on investment. ## Notable figures - At 17.3% efficiency, this panel is 4.5pp below the \*\*database\*\* median of 21.8% - Power density of 173.0 W/m² is 45.1 W/m² below \*\*database\*\* median (218.1 W/m²) - needs more roof space - At -0.45%/°C, loses 0.15pp more power per degree than \*\*database\*\* median (-0.30%/°C) - Weight of 22.5 kg (4.0 kg below \*\*database\*\* median of 26.5 kg) allows easier transport and roof mounting - In the top 96% for efficiency among all N-type panels ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/uEpT2fHgcKuHEJ_9KLDCgg-8ca75e958a45.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-300MH-72](https://comparepv.com/panel/ja-solar-ns-300mh-72) | 300 W | Cooler, lighter, +6.0 pp | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | Cooler, lighter, +6.0 pp | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, lighter, +5.8 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +5.8 pp | | [Gamko New Energy GKA182M300W](https://comparepv.com/panel/gamko-new-energy-gka182m300w) | 300 W | Lighter, +5.7 pp, +5 yr warranty | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | Lighter, +5.7 pp, +5 yr warranty | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +5.7 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +5.7 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +5.7 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +5.7 pp, +5 yr warranty | | [Hansol NB-AN3](https://comparepv.com/panel/hansol-nb-an3) | 280 W | -65 W, cooler, -0.5 pp | | [Hansol TB-AN3](https://comparepv.com/panel/hansol-tb-an3) | 300 W | -45 W, cooler, +0.7 pp | | [Hansol TD-AN3 320W](https://comparepv.com/panel/hansol-td-an3-320w) | 320 W | -25 W, -1.2 pp | | [Hansol TD-AN3 325W](https://comparepv.com/panel/hansol-td-an3-325w) | 325 W | -20 W, -1.0 pp | | [Hansol ND-AN3](https://comparepv.com/panel/hansol-nd-an3) | 330 W | -15 W, cooler, -0.8 pp | | [Hansol TD-AN3-335](https://comparepv.com/panel/hansol-td-an3-335) | 335 W | -10 W, -0.5 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | Cooler, +6.7 pp, +15 yr warranty | --- Source: https://comparepv.com/panel/hansol-td-an3-345 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
