A key advantage of this series is its **high power density**, which allows for greater energy generation from the same area and simplifies the BOS (Balance of System) design. Depending on the variant, S-Max utilizes modern approaches to solar cells, including N-type and **HJT technology** - which is valued for its stable operation at higher temperatures and good performance in low-sunlight conditions. For investors, **long warranties** and a focus on durability are also important. The series was marketed as being tested for hail resistance, which increases the safety of operation in more challenging conditions. S-Max is a sensible choice for C&I (Commercial and Industrial) applications, farms, and roofs with limited surface area, when you want to combine **high reliability** with above-average energy production without paying extra for competitor marketing. ## Notable figures - At 22.4% efficiency, this panel is on par with typical \*\*HJT 550-600W\*\* modules - Power density of 224.5 W/m² matches the \*\*HJT 550-600W\*\* median - Temperature coefficient of -0.26%/°C is 0.02pp worse than \*\*HJT 550-600W\*\* median (-0.24%/°C) - higher losses in summer heat - Ranked #4680 out of 14129 panels for efficiency in the database ## Questions ### What is TOPCon technology and why does the Shinson S-Max series use it? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that reduces recombination losses, achieving higher efficiency than conventional PERC cells. In the S-Max series, this translates to up to 720 Wp per module, better temperature stability, and lower power loss on hot days. For large-scale C&I and utility projects, every efficiency point has a direct impact on the overall LCOE of the system. ### What warranty do Shinson Technology S-Max panels carry? The S-Max series comes with a 30-year product warranty and a 30-year linear power output warranty. The manufacturer guarantees a defined minimum power level for three decades of operation. For developers financing PV farms or C&I installations, this is one of the most important parameters in the investment return calculation and project bankability assessment. ### What is the peak power output of a Shinson S-Max module and how much does it reduce construction costs? The top S-Max variant delivers 720 Wp per module. This high unit power reduces the total module count for a given capacity, shortens DC string runs, and lowers overall BoS costs. For a 1 MWp utility farm you need roughly 1,389 S-Max 720 Wp modules instead of over 1,600 at 600 Wp. Shinson claims BoS cost savings of more than 15% compared to lower-wattage modules. ### Are Shinson S-Max panels suitable for an industrial rooftop or warehouse? Yes - the S-Max series was designed primarily for commercial and industrial (C&I) rooftop systems and large-scale PV farms. Its high power density maximizes energy yield from the limited roof area of warehouses and production facilities. Before installation, the roof structure should be verified for load-bearing capacity, as 720 Wp modules have larger dimensions and correspondingly higher weight. ### Are Shinson S-Max panels hail-resistant? Yes. The S-Max series has successfully passed a 45 mm hailstone impact test. This is a meaningful durability credential for installations in regions prone to severe hailstorms. Hail resistance is one of the key resilience benchmarks Shinson highlights for this series, alongside the 30-year product and power output warranty. ### How do Shinson S-Max modules perform in overcast conditions and high summer temperatures? N-type TOPCon cells have a lower temperature coefficient (Pmax) than conventional PERC cells, meaning less power loss on hot days. N-type technology also delivers better performance under diffuse irradiance on cloudy days. For year-round installations in climates with frequent cloud cover, this translates to a measurably higher annual energy yield compared to older PERC-based modules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/hjt-580-600w-a798bf164117.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -20 W, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -25 W, lighter, +2.2 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +50 W, +1.9 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -30 W, 16 kg lighter, +1.9 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -40 W, lighter, +1.9 pp | | [Shinson Technology S345M48BPV](https://comparepv.com/panel/shinson-technology-s345m48bpv) | 345 W | -235 W, hotter, -9.1 pp | | [Shinson Technology S350M48BPV](https://comparepv.com/panel/shinson-technology-s350m48bpv) | 350 W | -230 W, hotter, -8.9 pp | | [Shinson Technology S355M48BPV](https://comparepv.com/panel/shinson-technology-s355m48bpv) | 355 W | -225 W, hotter, -8.7 pp | | [Shinson Technology S360M48BPV](https://comparepv.com/panel/shinson-technology-s360m48bpv) | 360 W | -220 W, hotter, -8.5 pp | | [Shinson Technology S365M48BPV](https://comparepv.com/panel/shinson-technology-s365m48bpv) | 365 W | -215 W, hotter, -8.3 pp | | [Shinson Technology S540M72P3BF](https://comparepv.com/panel/shinson-technology-s540m72p3bf) | 540 W | -40 W, hotter, -1.6 pp | | [Shinson Technology S545M72P3BF](https://comparepv.com/panel/shinson-technology-s545m72p3bf) | 545 W | -35 W, hotter, -1.3 pp | | [Shinson Technology S550M72P3BF](https://comparepv.com/panel/shinson-technology-s550m72p3bf) | 550 W | -30 W, hotter, -1.2 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +70 W, lighter, +2.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +65 W, lighter, +2.6 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +60 W, lighter, +2.4 pp | --- Source: https://comparepv.com/panel/shinson-technology-s580m72ht3bf Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
