These are **bifacial** modules, meaning they can utilize not only direct sunlight, but also reflected light from the ground - a significant advantage on roofs with light-colored membranes, on soil with gravel, or in PV farms with optimized albedo. A key feature is **N-type TOPCon technology**, which is valued for its low degradation over time and high efficiency even with lower sunlight - which is important in the Polish climate, especially in autumn and winter. The use of half-cut architecture and a **18BB multi-busbar** design improves current flow and reduces micro-crack losses, making it easier to maintain high yields over the long term. The Summit Pro is a good choice for investors in solar farms, large industrial rooftops, and projects where **long-term reliability** and predictable energy production are the top priorities. ## Notable figures - At 22.4% efficiency, this panel is 0.6pp below the \*\*TOPCon 700-750W\*\* median of 23.0% - Power density of 230.2 W/m² matches the \*\*TOPCon 700-750W\*\* median - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 700-750W\*\* median - Bifaciality factor of 70% can add 4-10% extra yield with reflective mounting surface - In the top 36% for efficiency among all TOPCon panels ## Questions ### How do the bifacial Techwise Solar Summit Pro panels differ from standard monofacial panels? The Summit Pro TW-720HT-01 modules have an active rear side that captures light reflected from the ground, roof, or nearby surfaces. This can add several up to over ten percent extra energy yield compared to a classic module, especially on light-colored roofs, gravel ground, or PV farms with high-albedo terrain. However, it requires proper mounting with clearance beneath the panel. ### What is N-type TOPCon technology in the TW-720HT-01 panels, and is it really better than PERC? N-type TOPCon is a cell technology using an additional passivation layer that reduces carrier recombination and lowers module degradation over time. In practice, this means higher efficiency, better performance in low or diffuse light, and a slower power decline over the years compared to older PERC cells. For Poland's climate with long autumns and winters, this translates into more stable energy production. ### What warranty comes with the Summit Pro TW-720HT-01 panels, and what exactly does it cover? Techwise Solar provides a 15-year product warranty covering material and workmanship defects, plus a 30-year power warranty guaranteeing a minimum performance level over that period. This is close to the standard set by leading manufacturers, giving investors predictability when planning return on investment, particularly for PV farm projects and large industrial rooftops. ### What is the maximum power output of the Summit Pro panel, and what installations is it suited for? The TW-720HT-01 module reaches a maximum power of 720 Wp, placing it among high-power panels. Such output per panel means fewer modules are needed to reach a target installation capacity, lowering mounting structure and labor costs. It is particularly well suited for PV farms and large industrial roofs where maximizing yield per square meter is a priority. ### Do the half-cut architecture and 18BB busbar design in the Summit Pro panels have a real impact on system durability? Yes. Half-cut cells reduce current losses and limit how partial shading affects the whole panel, while the 18-busbar (18BB) layout improves current distribution and reduces stress on individual current paths, lowering the risk of microcracks. In practice, this results in slower power degradation over the long term and more stable system performance throughout the warranty period. ### Is Techwise Solar Summit Pro TW-720HT-01 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 mainly assesses a supplier's financial stability and bankability rather than module quality itself. Summit Pro panels can still offer strong technical parameters, but for projects financed through loans or leasing, it's worth checking with your installer whether manufacturer tier status affects financing terms. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/tw-720ht-01-en-bf52f37d1723.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +2.8 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -40 W, lighter, +2.6 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +2.6 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -45 W, lighter, +2.4 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -45 W, lighter, +2.4 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -45 W, lighter, +2.4 pp | | [Techwise Solar TW-650HT](https://comparepv.com/panel/techwise-solar-tw-650ht) | 650 W | -65 W, lighter, -1.4 pp | | [Techwise Solar TW-655HT](https://comparepv.com/panel/techwise-solar-tw-655ht) | 655 W | -60 W, lighter, -1.3 pp | | [Techwise Solar TW-660HT](https://comparepv.com/panel/techwise-solar-tw-660ht) | 660 W | -55 W, lighter, -1.1 pp | | [Techwise Solar TW-665HT](https://comparepv.com/panel/techwise-solar-tw-665ht) | 665 W | -50 W, lighter, -5 yr warranty | | [Techwise Solar TW-670HT](https://comparepv.com/panel/techwise-solar-tw-670ht) | 670 W | -45 W, lighter, -5 yr warranty | | [Techwise Solar TW-720HT-01-700W](https://comparepv.com/panel/techwise-solar-tw-720ht-01-700w) | 700 W | -15 W, -0.5 pp | | [Techwise Solar TW-720HT-01-705W](https://comparepv.com/panel/techwise-solar-tw-720ht-01-705w) | 705 W | -10 W, -0.3 pp | | [Techwise Solar TW-720HT-01-710W](https://comparepv.com/panel/techwise-solar-tw-720ht-01-710w) | 710 W | Very close match | | [Techwise Solar TW-720HT-01-720W](https://comparepv.com/panel/techwise-solar-tw-720ht-01-720w) | 720 W | Very close match | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +90 W, cooler, +2.7 pp | --- Source: https://comparepv.com/panel/techwise-solar-tw-720ht-01-715w 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.
