This means limited availability (mainly distributor remaining stock) and potentially harder access to identical replacement modules for servicing. - **Lower efficiency than competing mono PERC** - Efficiency of 19.2-19.7% is noticeably lower than comparable 365 Wp Solaria PowerXT modules (20.2%), meaning less energy yield from the same roof area at equivalent power output. - **No bifacial technology** - The module is monofacial (is\_bifacial: false), so it cannot capture additional reflected irradiance from the ground - in ground-mount installations on reflective surfaces, newer bifacial panels can deliver higher yield at comparable rated power. ## About this series The HiKu CS3L-P series combines poly-crystalline PERC cells split using **half-cut** technology into a 2x60 layout, reducing resistive losses and noticeably lowering the risk of hot spots on partially shaded sections of the panel, for example from chimneys, antennas, or foliage. The lower internal current of the cells translates into reduced sensitivity to micro-cracks, which matters during transport and installation on roofs with difficult access. The module stands out with a **low temperature coefficient** for power, meaning it loses less energy on hot days compared to conventional panels, while a crossbar-reinforced aluminum frame delivers **high resistance to snow and wind loads**, making it a solid choice for installations in harsh climates. An IP68 junction box with three bypass diodes further protects the circuit against the effects of partial shading. The manufacturer backs the series with a **25-year linear power warranty** and a 12-year warranty on materials and workmanship, contributing to a lower LCOE over the system's lifetime. This is a solution for investors seeking proven, industrial-grade quality for mid-scale rooftop and ground-mount installations. ## Notable figures - Efficiency of 19.5% matches the \*\*PERC 0-400W\*\* median - At 194.6 W/m² power density, roof space requirements are typical for \*\*PERC 0-400W\*\* panels - Temperature coefficient of -0.36%/°C matches the \*\*PERC 0-400W\*\* median - Ranked #12663 out of 14005 panels for efficiency in the database ## Questions ### Is the Canadian Solar HiKu CS3L-P series still available for purchase? The HiKu CS3L-P series has been discontinued by Canadian Solar and replaced by newer TOPCon-based models with higher power output. Availability is now limited to remaining distributor stock. Check with a local supplier for current inventory; the manufacturer warranties (25-year power, 12-year product) remain valid regardless of the discontinuation. ### What is the actual power output of the Canadian Solar HiKu CS3L-P panel, and how many are needed for a typical 5 kWp system? The panel reaches a maximum power output of 365 Wp. To build a system of roughly 5 kWp, you would need approximately 14 modules. Thanks to PERC cell technology and the half-cut layout, the panels maintain stable performance even under partial irradiance, making it easier to plan smaller rooftop systems. ### Does half-cut technology in the HiKu CS3L-P actually help against shading, like from a chimney? Yes, splitting the cells into halves in a 2x60 layout reduces resistive losses and lowers the impact of partial shading on the whole panel. When a chimney or antenna shades part of the module, only the corresponding half loses output rather than the entire panel. Three bypass diodes in the IP68 junction box further protect the circuit from overheating in shaded sections. ### What warranty applies to Canadian Solar HiKu CS3L-P panels, and does it still hold now that the series is discontinued? The manufacturer provides a 12-year product warranty covering materials and workmanship, plus a 25-year linear power warranty. Discontinuation from current production does not void the warranty on units already sold, since Canadian Solar, as a tier 1 manufacturer, maintains warranty service for all its legacy product lines under the original purchase terms. ### How well do HiKu CS3L-P panels perform on hot days and under heavy snow load? Well — the module has a low power temperature coefficient, so it loses less energy during high heat than conventional polycrystalline panels. A cross-reinforced aluminum frame provides high resistance to snow and wind loads, making the series a solid choice for both hot climates and harsh winter conditions. ### Are HiKu CS3L-P panels bifacial, generating power from both sides? No, the HiKu CS3L-P series uses standard monofacial PERC cells and has no bifacial capability. The panel produces energy only from its front surface. Buyers looking for rear-side generation should consider bifacial models from other Canadian Solar lines, such as BiHiKu. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Canadian_Solar-Datasheet-HiKu_CS3L-P_EN-2-98a28267e0c5.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [SunLink LNSU-410M](https://comparepv.com/panel/sunlink-lnsu-410m) | 410 W | +50 W, heavier, +0.8 pp | | [SunLink LNSK-340M](https://comparepv.com/panel/sunlink-lnsk-340m) | 340 W | -20 W, +0.6 pp | | [SunLink LNSU-405M](https://comparepv.com/panel/sunlink-lnsu-405m) | 405 W | +45 W, heavier, +0.6 pp | | [Canadian Solar CS3K-330P](https://comparepv.com/panel/canadian-solar-cs3k-330p) | 330 W | -30 W, lighter, +0.4 pp | | [Canadian Solar CS3K-335MB-AG](https://comparepv.com/panel/canadian-solar-cs3k-335mb-ag) | 335 W | -25 W, +0.4 pp, +5 yr warranty | | [Canadian Solar CS3U-395P](https://comparepv.com/panel/canadian-solar-cs3u-395p) | 395 W | +35 W, heavier, +0.4 pp | | [SunLink LNSU-400M](https://comparepv.com/panel/sunlink-lnsu-400m) | 400 W | +40 W, heavier, +0.3 pp | | [SunLink LNSK-335M](https://comparepv.com/panel/sunlink-lnsk-335m) | 335 W | -25 W, +0.3 pp | | [Canadian Solar CS3L-325P](https://comparepv.com/panel/canadian-solar-cs3l-325p) | 325 W | -35 W, -1.9 pp | | [Canadian Solar CS3L-330P](https://comparepv.com/panel/canadian-solar-cs3l-330p) | 330 W | -30 W, -1.7 pp | | [Canadian Solar CS3L-335P](https://comparepv.com/panel/canadian-solar-cs3l-335p) | 335 W | -25 W, -1.4 pp | | [Canadian Solar CS3L-340P](https://comparepv.com/panel/canadian-solar-cs3l-340p) | 340 W | -20 W, -1.1 pp | | [Canadian Solar CS3L-345P](https://comparepv.com/panel/canadian-solar-cs3l-345p) | 345 W | -15 W, -0.8 pp | | [Canadian Solar CS3L-350P](https://comparepv.com/panel/canadian-solar-cs3l-350p) | 350 W | -10 W, -0.6 pp | | [Canadian Solar CS3L-355P](https://comparepv.com/panel/canadian-solar-cs3l-355p) | 355 W | -0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +150 W, cooler, +5.5 pp | --- Source: https://comparepv.com/panel/canadian-solar-cs3l-360p Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
