The 585–615 Wp power output per module directly lowers BoS costs (cabling, racking, string count) in commercial and utility-scale installations. - **21.7% Efficiency — Top-Tier Mono PERC M12 Parity** - The peak module efficiency of 21.7% is identical to direct competitors GCL-M12/60H (21.7%) and Risen TITAN (21.7%), confirming the series' position at the upper end of mono PERC technology on the M12 format with no performance compromise relative to rivals in the same class. - **Verified LID and LeTID Mitigation** - CSI Solar (the actual manufacturer) applies annealing process optimization that reduces LID and LeTID effects by up to 50%; independent DNV testing (2022) confirmed degradation rates below 0.5%. With degradation ≤0.55%/year after year one, the module retains a minimum of 84.8% of its nameplate power after 25 years of operation. - **Low Temperature Coefficient of −0.34%/°C** - This figure sits at the favorable end of the PERC technology range (typical: −0.34% to −0.38%/°C). At a module operating temperature of 65°C (rooftop in a Polish summer), thermal losses are approximately 8.5% versus ~10% for lower-performing PERC modules, meaningfully improving annual energy yield during the warm season. - **25-Year Linear Power Warranty** - The manufacturer guarantees degradation ≤2% in year one and ≤0.55%/year over the subsequent 24 years, providing revenue predictability for commercial installations and meeting the bankability requirements demanded by project finance lenders for utility-scale PV projects. ## Cons - **PERC Being Displaced by TOPCon** - By 2025, approximately 75% of Chinese module production has shifted to N-type (TOPCon/HJT), with PERC declining to ~25% market share. Peer comparable JA Solar JAM72D40 LB achieves 23.2% efficiency — 1.5 percentage points above the HiKu7 maximum. For long-duration investments (utility farms, PPAs), the risk of lower residual system value for PERC relative to new TOPCon modules is a tangible concern. - **Monofacial Only** - The CS7L-MS series offers no bifacial variant. In ground-mount installations over high-albedo surfaces (gravel, concrete, snow), bifacial modules routinely generate 5–15% more energy annually, directly reducing LCOE. The absence of this option limits the HiKu7's competitiveness in utility-scale projects post-2024. - **Depozit Solar Is an OEM Rebadger, Not a Manufacturer** - The actual cell and module manufacturer is CSI Solar (Canadian Solar); Depozit Solar operates as a Romanian distributor selling the product under its own brand. In the event of a serious warranty claim, Polish installers may encounter an extended service chain (installer → Depozit Solar → CSI Solar), creating risk of delays and ambiguous after-sales liability. ## About this series The HiKu7 series from Depozit Solar features photovoltaic modules based on large-format M12 (210 mm) cells using mono PERC technology, which allows for achieving very high individual power output while simultaneously reducing the number of panels needed to cover a roof or ground. Thanks to the **half-cut cell technology**, the modules exhibit significantly better tolerance to shading - partial shading of one section does not affect the performance of the entire panel, which is particularly important in cases of irregular roof shapes or architectural obstructions. The series also features advanced **protection against LID and LeTID degradation effects** - typical degradation processes for silicon cells caused by light exposure - which ensures that HiKu7 maintains stable performance for decades and generates fewer losses over a long time horizon. These modules are primarily designed for **commercial, industrial, and photovoltaic farm applications**, where high individual power output directly translates into a lower system cost per kWp and a shorter return on investment. The reinforced frame design provides resistance to extreme wind and snow loads. **A 25-year linear performance warranty** confirms the long-term reliability of this series and provides assurance of stable income from installations for many years. ## Notable figures - Efficiency of 21.7% matches the \*\*PERC 600-650W\*\* median - Power density of 217.3 W/m² packs 3.5 W/m² more into the same footprint vs \*\*PERC 600-650W\*\* median (213.8 W/m²) - Temperature coefficient of -0.34%/°C matches the \*\*PERC 600-650W\*\* median - Weight of 31.0 kg (3.0 kg below \*\*PERC 600-650W\*\* median of 34.0 kg) allows easier transport and roof mounting - In the top 53% for efficiency among all PERC panels ## Questions ### Do HiKu7 panels from Depozit Solar perform well under partial shading? Yes. The HiKu7 series uses half-cut cell technology based on large-format M12 (210 mm) mono PERC cells, which significantly reduces energy losses from partial shading. When shade covers only a portion of the module, the remaining cell strings continue operating at full output. This makes HiKu7 a strong choice for rooftops with chimneys, dormers, or other architectural obstructions that cause uneven shading. ### What warranty does Depozit Solar offer on the HiKu7 series? Depozit Solar provides a 12-year product warranty covering material and workmanship defects, plus a 25-year linear power output warranty. First-year power degradation is below 2%, with no more than 0.55% per year thereafter. After 25 years of operation, the module retains at least 84.8% of its rated power — placing HiKu7 among the better-warranted modules in its class. ### What is LID and LeTID protection in HiKu7 panels, and does it actually matter? LID (Light-Induced Degradation) and LeTID (Light and elevated Temperature Induced Degradation) are common power-loss phenomena in silicon PERC cells triggered by light exposure and elevated temperatures. The HiKu7 series applies advanced manufacturing processes to minimize these effects, so the module loses less power in its early months of operation and delivers higher cumulative energy yields — directly increasing returns from the installation over its full service life. ### What type of installations are HiKu7 panels with up to 615 Wp best suited for? The HiKu7 series is designed for commercial, industrial, and utility-scale solar farm applications. With a peak output of up to 615 Wp, large systems can be built using fewer modules, reducing costs for mounting hardware, cabling, and labor — directly lowering the system cost per kWp and shortening the payback period. For small residential rooftop systems, lighter and more compact modules are generally a better fit. ### What drives the 615 W peak output of HiKu7 modules, and what efficiency do they reach? The 615 Wp output results from three combined factors: large-format M12 (210 mm) cells that maximize active area per module, mono PERC cell technology delivering module efficiency of up to approximately 21.7%, and a half-cut cell layout that reduces resistive losses and improves performance at elevated temperatures. The result is one of the highest energy yields available in this module class without bifacial technology. ### Can HiKu7 panels handle heavy snow loads and strong winds? Yes. The HiKu7 series features a reinforced aluminum frame engineered for high mechanical resistance. Modules are certified to IEC standards for static load testing, making them well suited for climates with heavy snowfall — including mountainous regions — as well as ground-mount installations exposed to high wind pressure. The robust construction supports reliable long-term performance under demanding environmental conditions. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/CS-Datasheet-HiKu7_CS7L-MS_v241_EN-7ee322eca533.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, +3.5 pp, +5 yr warranty | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, +3.3 pp, +5 yr warranty | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, +3.1 pp, +5 yr warranty | | [Longi Solar LR8-66HVD-665M](https://comparepv.com/panel/longi-lr8-66hvd-665m) | 665 W | +50 W, cooler, +2.9 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (665W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-665w-class) | 665 W | +50 W, cooler, +2.9 pp | | [Huayao HY665-B144DSS](https://comparepv.com/panel/huayao-hy665-b144dss) | 665 W | +50 W, cooler, +2.9 pp | | [Sunpro Power SPDG665-BC132R12](https://comparepv.com/panel/sunpro-spdg665-bc132r12) | 665 W | +50 W, cooler, +2.9 pp | | [Depozit Solar CS7L-585MS](https://comparepv.com/panel/depozit-solar-cs7l-585ms) | 585 W | -30 W, -1.0 pp | | [Depozit Solar CS7L-590MS](https://comparepv.com/panel/depozit-solar-cs7l-590ms) | 590 W | -25 W, -0.9 pp | | [Depozit Solar CS7L-595MS](https://comparepv.com/panel/depozit-solar-cs7l-595ms) | 595 W | -20 W, -0.7 pp | | [Depozit Solar CS7L-600MS](https://comparepv.com/panel/depozit-solar-cs7l-600ms) | 600 W | -15 W, -0.5 pp | | [Depozit Solar CS7L-605MS](https://comparepv.com/panel/depozit-solar-cs7l-605ms) | 605 W | -10 W, -0.3 pp | | [Depozit Solar CS7L-610MS](https://comparepv.com/panel/depozit-solar-cs7l-610ms) | 610 W | Very close match | | [Gamko New Energy GKA210N120](https://comparepv.com/panel/gamko-new-energy-gka210n120) | 680 W | +65 W, +2.3 pp, +5 yr warranty | | [Gamko New Energy GKA210N120-675](https://comparepv.com/panel/gamko-new-energy-gka210n120-675) | 675 W | +60 W, +2.2 pp, +5 yr warranty | | [Q-SUN Solar QN-670HJT-01](https://comparepv.com/panel/q-sun-solar-qn-670hjt-01) | 670 W | +55 W, cooler, +2.0 pp | --- Source: https://comparepv.com/panel/depozit-solar-cs7l-615ms Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
