This status translates into strong financial backing of the warranty and simplifies project financing with lenders and insurers. - **Positive Power Tolerance (+0/+5 Wp)** - All variants in the 270–290 W range carry a positive power tolerance of 0/+5 Wp. In practice, both installer and investor can be confident the module will meet or exceed its rated output, reducing the risk of underestimating energy yield at the project level. - **IP68 Junction Box and MC4 Connectors** - The datasheet confirms an IP68 ingress protection rating for the junction box and standard MC4 connectors, accelerating installation and eliminating the need for additional adapter cabling even in legacy string array configurations. - **25-Year Linear Power Warranty** - The manufacturer guarantees at least 80% of nominal power output after 25 years — a warranty standard identical to contemporaneous Tier-1 modules from Trina Solar and JA Solar — protecting the asset value of the installation across its full operational lifetime. ## Cons - **Series Discontinued (since 2020)** - The HT60-156P / HT60-156P(V) was manufactured between 2012 and 2020 and is officially designated as discontinued. Availability of new modules is limited exclusively to distributor warehouse stock; after-sales support, matching replacement frames, and original junction boxes may be difficult to source in the event of a failure post-2025. - **Outdated Cell Technology vs. the 2025+ Market** - The series is based on P-type cells (polycrystalline/PERC), whereas the current market is dominated by N-type TOPCon and HJT technologies — both offering higher annual energy yield, lower LID/LETID degradation rates, and a superior temperature coefficient of power (≤ −0.30%/°C vs. −0.41%/°C for this series). For new installations, this results in a measurably lower annual energy yield per kWp. - **12-Year Product Warranty — Below Current Market Standard** - Current HT-SAAE N-type series (2024+) carry a 25-year product warranty. This series originally shipped with a 10-year product warranty, subsequently extended to 12 years — still significantly below the market standard of 15–25 years. When purchasing from warehouse stock, the remaining warranty coverage is further reduced accordingly. ## About this series The HT-SAAE HIGHWAY HT60-156P / HT60-156P(V) series are 60-cell modules based on **polycrystalline cells**, designed to combine stable performance with easy integration into common rooftop installations. In practice, their positive power tolerance stands out, offering the installer and investor greater predictability of energy yield under real-world conditions, without the risk that the module will perform below its declared specifications.

The (V) variant facilitates customization of the modules for various projects, particularly where compatibility with existing string configurations is crucial. The entire design is complemented by a weatherproof junction box with a high protection class and **MC4 connectors**, which shortens installation time and minimizes the risk of wiring errors. This is an excellent choice for homes, small businesses, and system upgrades in existing installations, where proven technology and reliable performance over years are essential. ## Notable figures - Efficiency of 17.2% is 2.2pp below the \*\*PERC 0-400W\*\* median (19.4%) - Power density of 172.1 W/m² is 22.3 W/m² below \*\*PERC 0-400W\*\* median (194.4 W/m²) - needs more roof space - Temperature coefficient of -0.41%/°C is 0.05pp worse than \*\*PERC 0-400W\*\* median (-0.36%/°C) - higher losses in summer heat - At 18.5 kg, this panel is 2.0 kg lighter than \*\*PERC 0-400W\*\* median (20.5 kg) - easier handling during installation - #13396 for efficiency, #13738 for temperature performance out of 14005 panels ## Questions ### Is the HT-SAAE HIGHWAY HT60-156P series still available for purchase? The HT-SAAE HIGHWAY HT60-156P / HT60-156P(V) series has been discontinued and is no longer in active production or standard distribution. If you need modules with similar specifications, newer HT-SAAE panels or other current Tier 1 offerings are the recommended alternative. Occasionally, units from this series may still surface as overstock or clearance inventory with select distributors. ### What warranty does the HT-SAAE HIGHWAY HT60-156P come with? The HT-SAAE HIGHWAY HT60-156P modules carry a 12-year product warranty covering materials and workmanship, plus a 25-year linear power output warranty. The power warranty guarantees the module maintains a specified minimum efficiency level over a quarter century — a Tier 1 standard commitment that secures the investor's return across the full operational lifetime of the system. ### Are the HT-SAAE HIGHWAY HT60-156P panels suitable for both pitched and flat roofs? Yes, the HT60-156P series is designed for pitched and flat roof installations alike. The aluminum frame and tempered glass deliver a robust structure capable of handling snow and wind loads typical of Central European climates. The high-IP-rated junction box and MC4 connectors are fully compatible with standard rail-based mounting systems used on both roof types. ### What is the difference between the HT60-156P and the HT60-156P(V) variant? The HT60-156P(V) variant features adjusted electrical parameters — typically a different open-circuit voltage or current configuration — making it easier to match existing string layouts in a PV system. This is particularly valuable when expanding or retrofitting an installation where string-level compatibility with the inverter's MPPT input range is critical to maintaining system performance. ### What does positive power tolerance mean for the HT-SAAE HIGHWAY HT60-156P, and why does it matter? Positive power tolerance means each module is guaranteed to meet or exceed its rated 290 Wp — it will never deliver less than the datasheet value. For installers and investors, this provides greater confidence in real-world energy yield projections and eliminates the risk of underperforming modules pulling down the overall output of the array. ### What type of installations are the 290 Wp polycrystalline HT-SAAE HIGHWAY HT60-156P modules best suited for? The HT60-156P series at 290 Wp is well suited for residential systems, small commercial applications, and retrofits of older PV installations where proven technology and long-term reliability are priorities. Ten modules produce a nominal 2.9 kWp system, covering a significant share of a typical household's electricity consumption. The series was also a practical choice for replacing modules in legacy systems with existing MC4 wiring infrastructure. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ht60-156p-en-full-cell-156-75mm-ee4cf661d6a9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Canadian Solar CS3K-330P](https://comparepv.com/panel/canadian-solar-cs3k-330p) | 330 W | +50 W, cooler, +2.7 pp | | [Canadian Solar CS3K-325P](https://comparepv.com/panel/canadian-solar-cs3k-325p) | 325 W | +45 W, cooler, +2.4 pp | | [SunLink LNSK-330M](https://comparepv.com/panel/sunlink-lnsk-330m) | 330 W | +50 W, cooler, +2.3 pp | | [Canadian Solar CS3K-320P](https://comparepv.com/panel/canadian-solar-cs3k-320p) | 320 W | +40 W, cooler, +2.1 pp | | [SunLink LNSK-325M](https://comparepv.com/panel/sunlink-lnsk-325m) | 325 W | +45 W, cooler, +2.0 pp | | [Canadian Solar CS3K-315P](https://comparepv.com/panel/canadian-solar-cs3k-315p) | 315 W | +35 W, cooler, +1.8 pp | | [HT-SAAE HT60-156P-270](https://comparepv.com/panel/ht-saae-ht60-156p-270) | 270 W | -10 W, -0.6 pp | | [HT-SAAE HT60-156P-275](https://comparepv.com/panel/ht-saae-ht60-156p-275) | 275 W | -0.3 pp | | [HT-SAAE HT60-156P-285](https://comparepv.com/panel/ht-saae-ht60-156p-285) | 285 W | +0.3 pp | | [HT-SAAE HT60-156P-290](https://comparepv.com/panel/ht-saae-ht60-156p-290) | 290 W | +10 W, +0.6 pp | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +5.4 pp, +15 yr warranty | | [Lina Energy LEPV 400](https://comparepv.com/panel/lina-energy-lepv-400) | 400 W | +120 W, cooler, +5.1 pp | | [Phono Solar NS-360MH-60](https://comparepv.com/panel/phono-solar-ns-360mh-60) | 360 W | +80 W, cooler, +4.9 pp | | [PolyCrown Solar Tech NS-360MH-60](https://comparepv.com/panel/polycrown-solar-tech-ns-360mh-60) | 360 W | +80 W, cooler, +4.9 pp | | [Maxeon SPR-MAX3-390-COM](https://comparepv.com/panel/maxeon-spr-max3-390-com) | 390 W | Cooler, +4.9 pp, +15 yr warranty | | [Meyer Burger MB\_TG120ByB\_390](https://comparepv.com/panel/meyer-burger-mb-tg120byb-390) | 390 W | +110 W, cooler, +4.6 pp | --- Source: https://comparepv.com/panel/ht-saae-ht60-156p-280 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
