The use of **N-type cells in TOPCon technology** helps minimize losses and maintain stable production even at higher temperatures and during periods of reduced sunlight. The module features **a monocrystalline structure**, which promotes high efficiency and predictable performance over a long lifespan, which will be appreciated by investors who are calculating the total cost of energy over the entire lifespan of the installation. In practice, the Sun-Pursuit Pro solves common problems with roofs of limited surface area - it allows you to generate more energy from the same number of modules, while also simplifying the design of the installation thanks to its refined electrical architecture. Another advantage is **an extended power warranty**, which is important for those who want to secure the profitability of their investment for years to come. This is a good solution for homes, businesses, and commercial projects where **high performance** and **reliable operation** are important in variable climatic conditions. ## Notable figures - At 21.4% efficiency, this panel is 1.2pp below the \*\*TOPCon 450-500W\*\* median of 22.5% - At 221.8 W/m², this panel generates 3.3 W/m² less per unit area than \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - At 23.0 kg, weight matches the \*\*TOPCon 450-500W\*\* median - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### How does TOPCon technology in Techwise Solar Sun-Pursuit Pro panels differ from standard monocrystalline PERC cells? The N-type cells with TOPCon technology used in the Sun-Pursuit Pro series reduce energy losses from carrier recombination, resulting in higher efficiency and a smaller power drop at high temperatures compared to classic P-type PERC cells. In practice, this means more stable energy production during summer and in high-irradiance regions where panels heat up significantly. ### Are Sun-Pursuit Pro TW-500HT-06 panels bifacial, and how much extra energy does that provide? Yes, the TW-500HT-06 series uses bifacial modules that also generate power from reflected light hitting the rear side of the panel. Depending on ground albedo, mounting height, and tilt angle, the additional energy yield can range from a few to over ten percent, especially on light-colored surfaces such as white metal roofing or gravel. ### What warranty comes with Techwise Solar Sun-Pursuit Pro TW-500HT-06 panels? The manufacturer provides a 15-year product warranty covering material and workmanship defects, along with a 30-year linear power warranty guaranteeing a minimum output level throughout that period. This exceeds the standard 10-12 year product warranty offered by many manufacturers, providing solid long-term protection for the investment's payback. ### Is it worth choosing 500 Wp panels over standard 400-450 Wp modules for a roof with limited space? Yes, the higher output of a single 500 Wp module allows for a greater total system capacity using the same number of panels or the same roof area, which is important when installation space is limited. This helps optimize the number of modules needed to reach the target system capacity, reducing mounting structure and labor costs. ### Are Sun-Pursuit Pro panels suitable for commercial installations and larger solar farms? Yes, the high efficiency of TOPCon cells combined with bifacial technology and 500 Wp output makes the Sun-Pursuit Pro series a solid choice for residential, commercial, and utility-scale solar farm projects, where maximizing energy yield per unit area matters. Stable performance under variable climate conditions also makes return-on-investment forecasting easier at scale. ### Is Techwise Solar a Tier 1 manufacturer, and does that matter when choosing panels? Techwise Solar is not currently listed as a Tier 1 manufacturer under the BloombergNEF classification, which is based primarily on bank project financing scale rather than product quality directly. It's worth focusing on actual technical specifications, such as the TOPCon technology used and the extended warranty terms, which in this series are competitive with many higher-tier brands. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/tw-500ht-06-en-37d3b6d325db.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +30 W, cooler, +3.6 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.4 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +25 W, cooler, +3.3 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.1 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +20 W, cooler, +3.1 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +20 W, cooler, +3.1 pp | | [Techwise Solar TW-445HT](https://comparepv.com/panel/techwise-solar-tw-445ht) | 445 W | Hotter, -0.8 pp, -5 yr warranty | | [Techwise Solar TW-450HT](https://comparepv.com/panel/techwise-solar-tw-450ht) | 450 W | -30 W, hotter, -5 yr warranty | | [Techwise Solar TW-455HT](https://comparepv.com/panel/techwise-solar-tw-455ht) | 455 W | -25 W, hotter, -5 yr warranty | | [Techwise Solar TW-460HT](https://comparepv.com/panel/techwise-solar-tw-460ht) | 460 W | -20 W, hotter, -5 yr warranty | | [Techwise Solar TW-500HTS-06-480](https://comparepv.com/panel/techwise-solar-tw-500hts-06-480) | 480 W | Cooler, -5 yr warranty | | [Techwise Solar TW-480HTS-06](https://comparepv.com/panel/techwise-solar-tw-480hts-06) | 480 W | Cooler, +0.8 pp, -5 yr warranty | | [Techwise Solar TW-485HT-06](https://comparepv.com/panel/techwise-solar-tw-485ht-06) | 485 W | +0.2 pp | | [Techwise Solar TW-500HTS-06-485](https://comparepv.com/panel/techwise-solar-tw-500hts-06-485) | 485 W | Cooler, -5 yr warranty | | [Techwise Solar TW-485HTS-06](https://comparepv.com/panel/techwise-solar-tw-485hts-06) | 485 W | Cooler, +1.0 pp, -5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +80 W, cooler, +3.4 pp | --- Source: https://comparepv.com/panel/techwise-solar-tw-480ht-06 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
