Thanks to the use of multi-busbar MBB cells, this design effectively reduces losses resulting from internal resistance, which directly translates into higher efficiency for the entire system. This series effectively addresses the problem of performance drops caused by partial shading, offering stable operation where traditional modules fail. The use of **PERC technology** allows for more efficient absorption of diffused light, making these panels an optimal choice for the Polish climate zone. This solution is primarily dedicated to single-family homeowners and small businesses looking for an **attractive price-to-quality ratio** without compromising on durability. The modules stand out with increased resistance to extreme snow and wind loads, guaranteeing safe use for decades. Unlike many competing products, the SPHM6-60L places special emphasis on **minimizing the risk of the hot-spot effect**, which protects the installation from overheating and failure. Choosing this series is a way to achieve **maximum energy cost optimization** while using proven, modern technological solutions. ## Notable figures - At 21.4% efficiency, this panel is on par with typical \*\*PERC 600-650W\*\* modules - At 213.8 W/m² power density, roof space requirements are typical for \*\*PERC 600-650W\*\* panels - At -0.34%/°C, hot weather performance is typical for \*\*PERC 600-650W\*\* panels - Weight of 30.9 kg (3.1 kg below \*\*PERC 600-650W\*\* median of 34.0 kg) allows easier transport and roof mounting - #8323 for efficiency, #8778 for temperature performance out of 14005 panels ## Questions ### Are SpolarPV SPHM6-60L panels still available for purchase? The SPHM6-60L series has been discontinued by SpolarPV. No new modules from this line are being manufactured, and availability is limited to remaining dealer stock. If you are planning a new installation, ask your distributor about currently produced alternatives featuring PERC half-cut technology in a comparable power range. ### What product warranty and power warranty does the SpolarPV SPHM6-60L carry? SpolarPV provides a 12-year product warranty covering material and workmanship defects. In addition, a 25-year linear power warranty guarantees that the modules will retain a specified percentage of their rated output over a quarter century. This is a standard coverage level for prosumer-grade PERC panels and secures the investment for well over two decades. ### What is PERC Half-Cut cell technology used in the SPHM6-60L series, and is it worth the premium? PERC (Passivated Emitter and Rear Cell) adds a passivation layer to the rear of each cell, improving absorption of diffuse light — a key advantage in Poland's frequently overcast climate. Half-cut means each cell is laser-cut in two, reducing internal resistance and resistive heat losses. Together, these technologies deliver higher real-world energy yield and better partial-shading tolerance than conventional full-cell modules. ### How do SpolarPV SPHM6-60L panels handle partial shading from a chimney or nearby trees? The half-cut architecture combined with multi-busbar (MBB) cells divides the SPHM6-60L module into independent electrical sub-strings. When shade falls on one section, only that section is affected while the rest of the panel continues producing at full capacity. In practice, this results in noticeably lower energy losses on rooftops with chimneys, dormers, or nearby vegetation compared to traditional full-cell modules. ### How much energy will a system built with SpolarPV SPHM6-60L 605 Wp panels generate per year? At a peak rating of 605 Wp, a single SPHM6-60L module will produce approximately 550–650 kWh annually under Polish irradiance conditions, depending on location, tilt angle, and shading. A 10-panel array (roughly 6 kWp) can cover the typical yearly consumption of a four-person household, estimated at 4,000–5,500 kWh. The precise figure always depends on system design and site-specific conditions. ### Are the SpolarPV SPHM6-60L panels bifacial, and are they suitable for a pitched roof? No, the SPHM6-60L series is monofacial — it generates electricity from the front surface only. This is entirely sufficient for standard residential rooftop installations; bifacial modules deliver meaningful gains mainly in ground-mounted systems over highly reflective ground surfaces. For a pitched residential roof the SPHM6-60L is a fully appropriate choice, backed by its rated resistance to extreme snow and wind loads. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/SP590-605HM6-60L-EN-2-a0b7e6ce44ef.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, +3.8 pp, +5 yr warranty | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, +3.6 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, +3.4 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.2 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, +3.2 pp, +5 yr warranty | | [SpolarPV SP590HM6-60L](https://comparepv.com/panel/spolarpv-sp590hm6-60l) | 590 W | -15 W, -0.6 pp | | [SpolarPV SP595HM6-60L](https://comparepv.com/panel/spolarpv-sp595hm6-60l) | 595 W | -10 W, -0.4 pp | | [SpolarPV SP600HM6-60L](https://comparepv.com/panel/spolarpv-sp600hm6-60l) | 600 W | Very close match | | [Gamko New Energy GKA210N120](https://comparepv.com/panel/gamko-new-energy-gka210n120) | 680 W | +75 W, +2.6 pp, +5 yr warranty | | [Gamko New Energy GKA210N120-675](https://comparepv.com/panel/gamko-new-energy-gka210n120-675) | 675 W | +70 W, +2.5 pp, +5 yr warranty | | [Q-SUN Solar QN-670HJT-01](https://comparepv.com/panel/q-sun-solar-qn-670hjt-01) | 670 W | +65 W, cooler, +2.3 pp | | [Gamko New Energy GKA210N120-670](https://comparepv.com/panel/gamko-new-energy-gka210n120-670) | 670 W | +65 W, +2.3 pp, +5 yr warranty | | [Q-SUN Solar QN-665HJT-01](https://comparepv.com/panel/q-sun-solar-qn-665hjt-01) | 665 W | +60 W, cooler, +2.1 pp | | [Gamko New Energy GKA210N120-665](https://comparepv.com/panel/gamko-new-energy-gka210n120-665) | 665 W | +60 W, +2.1 pp, +5 yr warranty | | [Sunpro Power SPDG660-N120M12](https://comparepv.com/panel/sunpro-spdg660-n120m12) | 660 W | +55 W, +1.9 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/spolarpv-sp605hm6-60l Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
