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 - Efficiency of 22.5% matches the \*\*HJT 700-750W\*\* median - Power density of 225.3 W/m² is 4.9 W/m² below \*\*HJT 700-750W\*\* median (230.2 W/m²) - needs more roof space - -0.26%/°C temperature coefficient - 0.02pp worse than \*\*HJT 700-750W\*\* median (-0.24%/°C), expect higher hot weather losses - Ranked #3982 out of 14005 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-700-720w-8bdd30f86c06.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | -50 W, lighter, +2.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | -20 W, lighter, +2.7 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -25 W, lighter, +2.5 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Lighter, +2.5 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Lighter, +2.4 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -30 W, lighter, +2.3 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -30 W, lighter, +2.3 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -30 W, lighter, +2.3 pp | | [Shinson Technology S650M66P4BF](https://comparepv.com/panel/shinson-technology-s650m66p4bf) | 650 W | -50 W, hotter, -1.6 pp | | [Shinson Technology S655M66P4](https://comparepv.com/panel/shinson-technology-s655m66p4) | 655 W | Hotter, -1.4 pp, -5 yr warranty | | [Shinson Technology S660M66P4BF](https://comparepv.com/panel/shinson-technology-s660m66p4bf) | 660 W | -40 W, hotter, -1.3 pp | | [Shinson Technology S665M66P4BF](https://comparepv.com/panel/shinson-technology-s665m66p4bf) | 665 W | -35 W, hotter, -1.1 pp | | [Shinson Technology S670M66P4](https://comparepv.com/panel/shinson-technology-s670m66p4) | 670 W | Hotter, -0.9 pp, -5 yr warranty | | [Shinson Technology S680M66NT4BF](https://comparepv.com/panel/shinson-technology-s680m66nt4bf) | 680 W | -20 W, hotter, -0.6 pp | | [Shinson Technology S685M66NT4BF](https://comparepv.com/panel/shinson-technology-s685m66nt4bf) | 685 W | -15 W, hotter, -0.5 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +105 W, heavier, +2.6 pp | --- Source: https://comparepv.com/panel/shinson-technology-s700m66ht4bf 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.
