This is a notably stronger degradation profile than the standard 25-year warranties with ~84.8% retention offered by many TOPCon competitors. - **Reduced shading losses in urban settings** - The soft-breakdown design cuts power loss under partial shading by up to 70% compared to standard TOPCon modules, translating into real-world yield gains for C&I installations on existing urban rooftops affected by chimneys, dormers, or trees. - **0BB (zero-busbar) design lowers resistive losses** - Replacing traditional busbars with 0BB technology reduces current transmission losses and improves interconnect durability, supporting stable power output over the full 30-year service life. - **Bankable Tier-1 manufacturer** - Founded in 2000, Longi Solar is one of the world's largest module manufacturers, reducing counterparty risk for C&I project financing and rooftop portfolios, and easing long-term warranty servicing. ## Cons - **No bifacial construction** - Unlike all three peer comparables (Sunpro Power TOPCon 210R Bifacial, Talesun BIPRO, RedSolar Bifacial), the Hi-MO X10 Explorer is not a bifacial module. This means no additional rear-side yield gain from reflected light (typically 3-8% depending on ground albedo), which may matter for ground-mount projects or rooftop farms over light-colored surfaces. ## About this series High-performance premium modules designed for maximum yield from the same surface area - especially where every square meter of roof matters or installation space is limited. The key advantage is the ****HPBC 2.0 back-contact technology****, which moves metalization to the rear side, improving light utilization and front-side aesthetics. In practice, this means higher energy yields in real-world conditions, not just in the lab. The series features ****n-type solutions**** and optimized passivation, resulting in more stable performance and less susceptibility to degradation over time. Additionally, the ****0BB (zero busbar) structure**** reduces current transmission losses and supports the longevity of connections. The ****optimized performance under shading conditions**** also deserves attention, minimizing losses in typical urban scenarios (chimneys, trees, window frames). This is an excellent choice for C&I installations, rooftop farms, and projects where high performance, reliability, and long-term profitability are key priorities. ## Notable figures - 23.3% module efficiency - 0.5pp better than the \*\*N-type 600-650W\*\* median of 22.8% - 233.2 W/m² power density - 5.5 W/m² more than \*\*N-type 600-650W\*\* median (227.7 W/m²), more power per roof area - -0.26%/°C temperature coefficient (median: -0.29%/°C) - retains ~1% more power at high temperatures - At 28.5 kg, this panel is 4.3 kg lighter than \*\*N-type 600-650W\*\* median (32.8 kg) - easier handling during installation - In the top 7% for efficiency among all N-type panels ## Questions ### What is HPBC 2.0 technology used in the LONGi Hi-MO X10 Explorer, and how does it compare to TOPCon or PERC? HPBC 2.0 (Hybrid Passivated Back Contact) is LONGi's proprietary architecture that moves all metallization to the rear of the module. With no front-side busbars blocking incoming light, the Hi-MO X10 Explorer achieves 24.1% module efficiency. The n-type wafer combined with bipolar passivation and a 0BB (zero busbar) structure limits annual power degradation to just 0.35%, giving it a clear edge over conventional PERC and TOPCon modules. ### What warranty does the LONGi Hi-MO X10 Explorer LR7-72HVH carry? LONGi provides a 15-year product warranty covering materials and workmanship, plus a 30-year linear power output warranty. From year 2 onward, annual degradation is capped at 0.35%, ensuring high performance across three decades of operation. As a Tier 1 manufacturer with strong financials, LONGi's warranty commitments are considered highly bankable by independent analysts and project lenders. ### Do the Hi-MO X10 Explorer panels work well on rooftops partially shaded by chimneys, trees, or dormers? Yes. The 0BB (zero busbar) design and built-in shade optimization significantly reduce mismatch losses common in urban rooftop environments. The series is specifically engineered for installations where architectural elements can shadow part of the array. Pairing the modules with string-level power optimizers or microinverters further minimizes shading losses and maximizes overall system yield. ### What are the dimensions and weight of the LONGi Hi-MO X10 Explorer, and is it suitable for installation on a pitched roof? The module measures 2382×1134×30 mm and weighs 28.5 kg. Its large-format 144-cell (6×24) layout requires at least two installers and proper lifting equipment on pitched roofs. The anodized aluminum frame and 3.2 mm tempered coated glass provide a front-load rating of 5400 Pa for snow loads and pass the 25 mm hailstone impact test at 23 m/s. ### How does the Hi-MO X10 Explorer perform in cold weather and low-light winter conditions? Exceptionally well. The power temperature coefficient is -0.260%/°C, noticeably better than standard PERC modules at around -0.35%/°C. On a cold but sunny winter day, the panel retains more output than older-generation technology. N-type cells also exhibit lower susceptibility to Light-Induced Degradation (LID), contributing to consistent, reliable long-term performance throughout the full service life. ### What type of installation is the LONGi Hi-MO X10 Explorer best suited for - residential, commercial, or utility-scale? The series is optimized primarily for commercial and industrial (C&I) applications - warehouses, logistics centers, and large rooftop arrays - where maximizing energy yield per unit area is critical. Up to 650 W per module and 24.1% efficiency allow more power to be packed into a constrained footprint. It is also a strong choice for large prosumer installations where fast LCOE reduction and return on investment are top priorities. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/lr-7-72-hvh-630-650-m-30-30-and-15-explorer-bgv-02-20241118-c7c91b4a288b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +20 W, lighter, +1.9 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +50 W, +1.9 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +45 W, +1.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +15 W, lighter, +1.7 pp | | [WINAICO WST-675BKX72-A2](https://comparepv.com/panel/winaico-wst-675bkx72-a2) | 675 W | +45 W, heavier, +1.7 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +40 W, +1.5 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +40 W, +1.5 pp | | [Longi Solar LR8-66HGD-595M](https://comparepv.com/panel/longi-lr8-66hgd-595m) | 595 W | -35 W, heavier, -1.3 pp | | [Longi Solar LR7-72HGD-600M](https://comparepv.com/panel/longi-lr7-72hgd-600m) | 600 W | -30 W, heavier, -1.1 pp | | [Longi Solar 600M](https://comparepv.com/panel/longi-600m) | 600 W | -30 W, -0.9 pp, -5 yr warranty | | [Longi Solar LR7-72HTH-605M](https://comparepv.com/panel/longi-lr7-72hth-605m) | 605 W | -25 W, -0.9 pp, -5 yr warranty | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +70 W, heavier, +1.7 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +65 W, heavier, +1.6 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +40 W, heavier, +1.5 pp | --- Source: https://comparepv.com/panel/longi-lr7-72hvh-630m 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.
