Space saver, short guarantee
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.

The 120-cell half-cut configuration halves the current in each substring, reducing resistive losses and improving tolerance to partial shading. The 585–615 Wp power output per module directly lowers BoS costs (cabling, racking, string count) in commercial and utility-scale installations.
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.
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.
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.
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.
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.
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.
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.
- 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
