This series has been designed to maximize yields from limited roof space, making it an ideal choice for both modern home installations and large-scale commercial farms. A key technological differentiator is the advanced **Multi-Busbar (MBB) system**, which effectively reduces losses resulting from internal resistance and minimizes the risk of harmful micro-cracks. Thanks to a low temperature coefficient, these modules maintain high efficiency even during hot summer days, directly solving the problem of power drops under intense sunlight. The durable frame construction ensures exceptional resistance to extreme mechanical loads, guaranteeing the safety and reliability of the system for decades. By choosing SERIES 6, the investor receives **full protection against the PID effect** and excellent performance characteristics in diffused light, which clearly distinguishes these products from cheaper alternatives. This is a solution dedicated to professionals for whom the priority is **high power density** and maximum investment profitability in the long-term perspective. ## Notable figures - At 20.9% efficiency, this panel is 0.9pp below the \*\*database\*\* median of 21.8% - 209.2 W/m² power density is 8.8 W/m² below \*\*database\*\* median (218.1 W/m²) - requires larger installation area - Temperature coefficient of -0.34%/°C is 0.04pp worse than \*\*database\*\* median (-0.30%/°C) - higher losses in summer heat - At 34.0 kg, this panel is 7.5 kg heavier than the \*\*database\*\* median (26.5 kg) - more demanding for installation crews - In the top 72% for efficiency among all N-type panels ## Questions ### What warranty does the Sunlike Solar SERIES 6 come with? Sunlike Solar backs the SERIES 6 with two separate warranties: a 12-year product warranty covering defects in materials and workmanship, and a 25-year linear power output warranty. The 25-year power guarantee lets homeowners and commercial investors confidently calculate long-term return on investment, knowing the modules will maintain rated performance for a quarter of a century. ### Do Sunlike Solar SERIES 6 675 W panels lose significant power output during hot summer days? The SERIES 6 uses PERC M10 cells with a low temperature coefficient, which limits power loss at high operating temperatures compared to older-generation modules. This means the panels continue generating strong output during peak summer heat, directly improving annual energy yield and lowering the effective LCOE of the installation over its lifetime. ### What is Multi-Busbar (MBB) technology in the SERIES 6 and why does it matter? Multi-Busbar replaces a few thick busbars with many thin wires spread across the cell surface. This shortens the current path, reducing resistive losses and significantly lowering the risk of microcracks forming during shipping and operation. For the system owner it means higher module efficiency and better durability across the full 25-year power warranty period. ### Is the Sunlike Solar SERIES 6 a bifacial or monofacial module? The Sunlike Solar SERIES 6 is a monofacial module — it captures sunlight from the front face only and does not feature bifacial cell technology. This eliminates the need for a high-albedo ground surface or elevated racking structures required by bifacial modules, simplifying system design and keeping balance-of-system (BoS) costs lower. ### What is PID and are SERIES 6 panels protected against it? Potential Induced Degradation (PID) is a gradual power loss caused by high system voltage and moisture penetrating the module. It is a serious concern in large-scale string inverter systems running at 1000–1500 V DC. Sunlike Solar SERIES 6 panels are engineered with full PID resistance, ensuring rated power output is maintained throughout the entire 25-year performance warranty. ### Do M10 PERC cells in the SERIES 6 deliver more power from a limited roof area? Yes. The M10 wafer format (182 mm) is one of the latest cell generations in high-volume production. Combined with PERC technology and Multi-Busbar interconnection, it enables high power density per square meter. The SERIES 6 reaches up to 675 Wp per panel, delivering more kilowatts from the same roof footprint than modules based on older 166 mm or 156 mm cell formats. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/210-132CELL-650-670W-TRANSPARENT-BS-6c1d23b19bd7.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +4.3 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +4.3 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +4.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +4.1 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +50 W, cooler, +4.1 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, +4.0 pp, +5 yr warranty | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +3.9 pp | | [Sunlike Solar LNET-655M](https://comparepv.com/panel/sunlike-solar-lnet-655m) | 655 W | Very close match | | [Sunlike Solar LNET-660M](https://comparepv.com/panel/sunlike-solar-lnet-660m) | 660 W | +10 W, +0.3 pp | | [Sunlike Solar LNET-665M](https://comparepv.com/panel/sunlike-solar-lnet-665m) | 665 W | +15 W, +0.5 pp | | [Sunlike Solar LNET-670M](https://comparepv.com/panel/sunlike-solar-lnet-670m) | 670 W | +20 W, +0.6 pp | | [Sunlike Solar LNET-675M](https://comparepv.com/panel/sunlike-solar-lnet-675m) | 675 W | +25 W, +0.8 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +155 W, cooler, +4.2 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +150 W, cooler, +4.0 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +145 W, cooler, +3.9 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +140 W, cooler, +3.7 pp | --- Source: https://comparepv.com/panel/sunlike-solar-lnet-650md Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
