These modules are designed to maximize yields in harsh environmental conditions, making them an ideal solution for solar farms and large industrial roofs. A key differentiator is the **advanced PERC structure**, which allows for efficient conversion of light at various angles of incidence, ensuring stable power production even on cloudy days. Investors appreciate this series for its exceptional **resistance to potential-induced degradation (PID)**, which guarantees long-term longevity and the financial predictability of the project. Unlike standard solutions, SPHM6-72L offers a better temperature coefficient, translating into higher yields during hot summer months. The use of a **reinforced frame design** allows for safe installation in regions exposed to extreme snow and wind loads, eliminating the risk of micro-cracks. By choosing this series, you gain the certainty that the system will maintain the highest efficiency for decades, effectively optimizing the LCOE of every kilowatt-hour produced. ## Notable figures - Efficiency of 20.3% is 0.6pp below the \*\*PERC 500-550W\*\* median (20.9%) - 203.4 W/m² power density is 5.6 W/m² below \*\*PERC 500-550W\*\* median (209.0 W/m²) - requires larger installation area - Temperature coefficient of -0.35%/°C matches the \*\*PERC 500-550W\*\* median - Ranked #11769 out of 14005 panels for efficiency in the database ## Questions ### Is the SpolarPV SPHM6-72L series still available for purchase? No, the SPHM6-72L series has been discontinued and is no longer actively distributed by SpolarPV. If you need modules with similar specs — PERC Half-Cut technology, high unit power output — ask your distributor about current alternatives from the same product line or comparable modules from other manufacturers. Remaining warehouse stock may still be available through select suppliers. ### What warranty does the SpolarPV SPHM6-72L solar panel series come with? SpolarPV provides a 12-year product warranty covering material and workmanship defects, along with a 25-year linear power output warranty guaranteeing the panel retains a specified percentage of its original efficiency over a quarter century. This is a standard level for the commercial segment, though it is worth noting that SpolarPV is not listed as a Bloomberg Tier 1 manufacturer, which may be relevant for project financing. ### What is the Half-Cut PERC cell technology used in the SPHM6-72L panels, and is it worth it? Half-Cut splits each PERC cell into two halves, reducing internal resistance and heat losses. The result: the module generates more energy at the same irradiance and handles partial shading better — a fault in one cell string does not shut down the entire panel. The PERC structure further reflects unabsorbed photons back into the cell, pushing conversion efficiency above standard mono or polycrystalline cells. ### How do the 560 Wp SPHM6-72L panels perform under partial shading and overcast conditions? Thanks to Half-Cut technology, the module is electrically split into two independent sections. Shading on part of the panel — from a chimney or a mounting rail, for example — limits losses to that section only, rather than the entire module as with conventional cells. The PERC structure also improves low-light harvesting, delivering better energy yields on the overcast days typical of Central European climates. ### Can the SpolarPV SPHM6-72L panels withstand heavy snow loads and strong winds? Yes, the SPHM6-72L series features a reinforced aluminum frame engineered for extreme weather conditions. The structure minimizes the risk of micro-cracks under mechanical stress. Exact allowable snow load and wind pressure values are listed in the product datasheet — consult a structural engineer before installing in mountainous regions or particularly exposed sites. ### Are the 560 Wp SPHM6-72L panels suitable for residential rooftop installations? Generally, no — this is not the optimal choice for a typical single-family home. The 72-cell format and 560 Wp output mean large dimensions and significant module weight, making transport and mounting on a steep pitched roof difficult. The SPHM6-72L series is designed for utility-scale and large industrial rooftop installations, where logistics are easier and the large panel size helps reduce the overall LCOE of the system. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/SP525-560HM6-72L-EN-3-82342b706944.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +4.7 pp, +5 yr warranty | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +4.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +4.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +4.4 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +4.3 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +4.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +4.2 pp, +5 yr warranty | | [SpolarPV SP530HM6-72L](https://comparepv.com/panel/spolarpv-sp530hm6-72l) | 530 W | Very close match | | [SpolarPV SPV535-PM10-144](https://comparepv.com/panel/spolarpv-spv535-pm10-144) | 535 W | Lighter, +0.4 pp, +5 yr warranty | | [SpolarPV SPV540-PM10-144](https://comparepv.com/panel/spolarpv-spv540-pm10-144) | 540 W | +15 W, +0.6 pp, +5 yr warranty | | [SpolarPV SPV545-PM10-144](https://comparepv.com/panel/spolarpv-spv545-pm10-144) | 545 W | +20 W, +0.8 pp, +5 yr warranty | | [SpolarPV SPV550-PM10-144](https://comparepv.com/panel/spolarpv-spv550-pm10-144) | 550 W | +25 W, +1.0 pp, +5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +125 W, cooler, +4.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +120 W, cooler, +4.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +115 W, cooler, +4.5 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +110 W, cooler, +4.3 pp | --- Source: https://comparepv.com/panel/spolarpv-sp525hm6-72l Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
