This solution directly addresses the needs of investors seeking maximum yields from limited roof space, eliminating the problem of energy loss in less favorable weather conditions. A key differentiator of this series is its **exceptional resistance to high temperatures**, which allows for stable power production on hot summer days when traditional modules lose their efficiency. The use of **N-type cells** makes the panels almost completely free from the light-induced degradation effect, ensuring long-term energy security and higher power output after many years of operation. Sun-Pursuit TW-415HT-1 stands out from the competition with its **excellent performance in low light**, generating energy more efficiently at dawn and dusk. This product is dedicated to demanding residential users and companies that prioritize uncompromising quality and modern design. Thanks to its reinforced construction and innovative cell architecture, this series provides investors with a faster return on investment and reliability that outpaces standard solutions available on the Polish photovoltaic market. By choosing this model, you gain the certainty of operating at peak performance for decades. ## Notable figures - At 20.7% efficiency, this panel is on par with typical \*\*PERC 400-450W\*\* modules - Power density of 207.4 W/m² matches the \*\*PERC 400-450W\*\* median - At -0.35%/°C, hot weather performance is typical for \*\*PERC 400-450W\*\* panels - At 20.8 kg, this panel is 1.2 kg lighter than \*\*PERC 400-450W\*\* median (22.0 kg) - easier handling during installation - #10645 for efficiency, #10419 for temperature performance out of 14005 panels ## Questions ### What cell technology is used in the Sun-Pursuit TW-415HT-1 panels? The Sun-Pursuit TW-415HT-1 series uses proven PERC (Passivated Emitter and Rear Cell) technology, which improves conversion efficiency compared to standard modules through a passivated rear surface. This allows the panel to reach up to 415 Wp while staying competitively priced, making the series a solid choice for residential and commercial installations focused on value for money. ### What warranty comes with the Techwise Solar Sun-Pursuit TW-415HT-1 panels? The manufacturer provides a 12-year product warranty covering material and workmanship defects, along with a 25-year linear power output warranty. This means that even after a quarter century of use, the panel should still deliver a significant share of its original rated power, giving investors a predictable return on their solar installation. ### Are the Sun-Pursuit TW-415HT-1 panels bifacial? No, the TW-415HT-1 series consists of monofacial modules rather than bifacial ones. The panels generate power only through the front, sun-facing surface, which is the standard configuration for typical sloped-roof installations. This means they don't require a bright, reflective ground surface that bifacial modules often need for optimal performance on flat roofs or ground mounts. ### Is Techwise Solar a Tier 1 manufacturer, and does that matter when buying? Techwise Solar is not currently listed as a Tier 1 manufacturer under BloombergNEF's classification, indicating a smaller production scale and shorter financial track record than the top-tier brands. This doesn't necessarily mean lower quality, but buyers should confirm local distributor support, warranty service terms, and whether their financing bank accepts non-Tier 1 panels before purchasing. ### How do the Sun-Pursuit TW-415HT-1 panels perform on hot summer rooftops? PERC cells have a moderately good temperature coefficient, so power loss from roof heating on hot days is limited, though somewhat higher than in more expensive heterojunction technologies. In practice, this translates to stable, predictable energy production even during high-irradiance summer months in a temperate climate. ### Is the Sun-Pursuit TW-415HT-1 suitable for a standard sloped-roof residential installation? Yes, the 415 Wp power rating and typical module dimensions fit well with the most common mounting systems used on sloped residential roofs. The 12-year product warranty and 25-year power warranty add reassurance for investors planning a long-term installation, though it's worth confirming local warranty service availability with the distributor before purchase. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/tw-415ht-1-en-412d9706b0f6.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | +50 W, cooler, +2.6 pp | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | +50 W, cooler, +2.6 pp | | [Yingli YL455CF54 e/2](https://comparepv.com/panel/yingli-yl455cf54-e-2) | 455 W | +50 W, cooler, +2.6 pp | | [Einnova Solarline ESM-455T](https://comparepv.com/panel/einnova-solarline-esm-455t) | 455 W | +50 W, +2.6 pp, +5 yr warranty | | [SunEvo Solar SE5-54HBC-455W](https://comparepv.com/panel/sunevo-solar-se5-54hbc-455w) | 455 W | +50 W, cooler, +2.6 pp | | [Just Solar JST-EDMH-(445-465)W-TD (455W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-455w-class) | 455 W | +50 W, +2.6 pp, +5 yr warranty | | [Luxor Solar LX-455M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-455m-182r-96-gg) | 455 W | +50 W, cooler, +2.6 pp | | [Techwise Solar TW-400HTB-1](https://comparepv.com/panel/techwise-solar-tw-400htb-1) | 400 W | -0.3 pp | | [Techwise Solar TW-410HTB-1](https://comparepv.com/panel/techwise-solar-tw-410htb-1) | 410 W | +0.3 pp | | [Techwise Solar TW-415HT-1](https://comparepv.com/panel/techwise-solar-tw-415ht-1) | 415 W | +10 W, +0.5 pp | | [Techwise Solar TW-425HT-06](https://comparepv.com/panel/techwise-solar-tw-425ht-06) | 425 W | Cooler, +1.0 pp, +5 yr warranty | | [Techwise Solar TW-430HT-06](https://comparepv.com/panel/techwise-solar-tw-430ht-06) | 430 W | Cooler, +1.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +105 W, cooler, +4.3 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +90 W, cooler, +4.1 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +100 W, cooler, +4.0 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +85 W, cooler, +3.8 pp | --- Source: https://comparepv.com/panel/techwise-solar-tw-405ht-1 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
