This solution not only increases the active surface area of the module but, above all, significantly reduces the risk of hot-spots and micro-cracks, which translates into higher long-term reliability. A unique advantage of this line is its **eco-friendly lead-free design**, making it one of the most sustainable choices on the market, perfectly aligning with strict environmental standards. Users looking for aesthetics will appreciate the **elegant, modern design**, which blends perfectly with various roofing materials while maintaining high resistance to extreme mechanical loads. This series effectively addresses the problem of energy losses resulting from partial shading, offering significantly better performance characteristics in demanding lighting conditions than standard competitor modules. It is an optimal solution for residential and commercial installations where the priority is **maximizing yields per square meter** while maintaining low investment costs. TERRA 5K stands out on the market with a unique combination of an innovative **structure with high resistance to PID degradation** and care for the product's natural life cycle. ## Notable figures - Module efficiency of 20.9% is 0.9pp below average for \*\*database\*\* panels (median: 21.8%) - 209.0 W/m² power density is 9.1 W/m² below \*\*database\*\* median (218.1 W/m²) - requires larger installation area - -0.34%/°C temperature coefficient - 0.04pp worse than \*\*database\*\* median (-0.30%/°C), expect higher hot weather losses - At 20.8 kg, this panel is 5.7 kg lighter than \*\*database\*\* median (26.5 kg) - easier handling during installation - Ranked #10148 out of 14129 panels for efficiency in the database ## Questions ### What is the shingled technology used in the Tongwei TERRA 5K series and what benefits does it offer? Shingled technology cuts cells into narrow strips and interconnects them without traditional solder ribbons, eliminating gaps between cells. This increases the module's active surface area and boosts energy yield from the same roof space. Removing ribbon connections also significantly lowers the risk of hot spots and microcracks, resulting in higher long-term reliability. ### What warranty comes with Tongwei TERRA 5K panels? The manufacturer provides a 15-year product warranty covering material and workmanship defects, plus a 25-year power output warranty guaranteeing a minimum energy generation level over that period. Tongwei is a Tier 1 manufacturer, which adds further confidence that these warranty commitments will be honored throughout the system's lifetime. ### How many TERRA 5K panels are needed to build a 5 kWp installation? TERRA 5K panels reach a maximum power of 425 Wp, so a roughly 5 kWp installation typically requires 12 panels (12 × 425 W ≈ 5.1 kWp). The exact number depends on available roof area, roof pitch, and inverter sizing, so it's best to confirm the final design with an installer. ### Are TERRA 5K panels suitable for mounting on a pitched residential roof? Yes, the TERRA 5K series is designed for residential installations, including pitched roofs. Its sleek, uniform black appearance blends well with common roofing materials, and the module's build offers strong mechanical resistance to snow and wind loads typical of sloped-roof mounting. ### Is the Tongwei TERRA 5K a bifacial panel? No, the TERRA 5K is a monofacial panel, generating power only from its front side. This is a standard choice for typical pitched-roof installations, where the rear side wouldn't receive reflected light anyway. It also keeps installation simpler and cheaper than bifacial systems, which require special mounting structures. ### What does it mean that TERRA 5K is a lead-free panel, and why does it matter? Thanks to shingled technology without traditional soldered ribbons, the panel's lead content is significantly reduced compared to conventional modules. This is an eco-friendly design choice that helps meet strict environmental standards and simplifies future recycling. For buyers, it means a more sustainable product without any trade-off in performance or durability. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/TW-Solar-5K-44SCF-DE-6b2faf6b148f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | +50 W, +2.9 pp, +5 yr warranty | | [Luxor Solar LX-465M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-465m-182r-96-gg) | 465 W | +50 W, cooler, +2.9 pp | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | Cooler, +2.7 pp, +5 yr warranty | | [Luxor Solar LX-465M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-465m-182r188-108-gg) | 465 W | +50 W, cooler, +2.7 pp | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +45 W, +2.7 pp, +5 yr warranty | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | Cooler, +2.7 pp, +5 yr warranty | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | Cooler, +2.6 pp, +5 yr warranty | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | Cooler, +2.6 pp, +5 yr warranty | | [Tongwei TH400PMB7-44SCF](https://comparepv.com/panel/tongwei-solar-tw-solar-th400pmb7-44scf) | 400 W | -15 W, -0.8 pp | | [Tongwei TH405PMB7-44SCF](https://comparepv.com/panel/tongwei-solar-tw-solar-th405pmb7-44scf) | 405 W | -10 W, -0.5 pp | | [Tongwei TH410PMB7-44SCF](https://comparepv.com/panel/tongwei-solar-tw-solar-th410pmb7-44scf) | 410 W | -0.3 pp | | [Tongwei TH420PMB7-44SCF](https://comparepv.com/panel/tongwei-solar-tw-solar-th420pmb7-44scf) | 420 W | +0.2 pp | | [Tongwei TH425PMB7-44SCF](https://comparepv.com/panel/tongwei-solar-tw-solar-th425pmb7-44scf) | 425 W | +10 W, +0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +95 W, cooler, +4.1 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +80 W, cooler, +3.9 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +90 W, cooler, +3.8 pp | --- Source: https://comparepv.com/panel/tongwei-solar-tw-solar-th415pmb7-44scf Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
