Splitting each cell in half reduces the internal current flowing through the panel, resulting in lower hot-spot temperatures and a gentler impact of micro-cracks on overall module performance. This approach is especially effective in installations exposed to partial shading from chimneys, antennas, or neighboring buildings, since conventional panels lose considerably more energy under such conditions. Built around a **reinforced, crossbar-enhanced frame**, the panel delivers strong mechanical resistance to snow and wind loads, making it well suited for roofs in regions with demanding climate conditions. A **low power temperature coefficient** limits output drops on hot days, and the series is backed by a **25-year linear power warranty** along with a 12-year product warranty, contributing to a lower LCOE and reduced installation cost per watt. The HiKu CS3W-P is a proven choice for installers seeking a versatile module for both rooftop and ground-mount applications, combining reliability with an attractive price-to-performance ratio. ## Notable figures - Module efficiency of 18.8% is 1.8pp below average for \*\*PERC 400-450W\*\* panels (median: 20.6%) - Power density of 187.8 W/m² is 18.3 W/m² below \*\*PERC 400-450W\*\* median (206.2 W/m²) - needs more roof space - Temperature coefficient of -0.36%/°C matches the \*\*PERC 400-450W\*\* median - At 24.9 kg (2.9 kg above \*\*PERC 400-450W\*\* median of 22.0 kg), requires checking roof load capacity - #13033 for efficiency, #12345 for temperature performance out of 14005 panels ## Questions ### Is the Canadian Solar HiKu CS3W-P 440W panel still available for purchase? The HiKu CS3W-P series has been discontinued and replaced by newer models using TOPCon cell technology. Panels from this series may still be found through distributors clearing existing stock, but availability is limited. When buying, check the production date and confirm the manufacturer's warranty still applies despite the end of production. ### What warranty comes with Canadian Solar HiKu CS3W-P panels? The manufacturer covers the HiKu CS3W-P series with a 12-year product warranty and a 25-year linear power warranty, guaranteeing a minimum performance level throughout its service life. This is standard for Tier 1 panels, though newer Canadian Solar TOPCon models now offer extended 30-year power warranties. ### How do the half-cut cells in the HiKu CS3W-P differ from standard full-size cells? The half-cut cells in the HiKu CS3W-P series are cut in half and arranged in two rows of 144 cells, reducing the current flowing through each cell. This lowers heat generation at hot-spot points, improves resistance to microcracks, and reduces power loss under partial shading, such as from a chimney or antenna, compared to conventional full-cell modules. ### Is the HiKu CS3W-P 440W panel suitable for roofs with heavy snow or wind loads? Yes, the module's design features a reinforced frame with additional crossbars, increasing mechanical strength against snow and wind loads. This makes the HiKu CS3W-P well-suited for roofs in regions with more demanding climate conditions, where standard frames might deform or crack under snow pressure. ### Are HiKu CS3W-P panels bifacial and able to capture reflected light? No, the HiKu CS3W-P series is a monofacial module using PERC cell technology without an active rear surface. The panel generates energy only from direct and diffuse light hitting the front side. For additional energy gain from ground reflection, consider Canadian Solar's newer bifacial TOPCon models instead. ### How does PERC technology in the HiKu CS3W-P affect panel efficiency on hot days? HiKu CS3W-P panels have a low power temperature coefficient, limiting output drops during high summer temperatures. PERC technology, with its rear reflective layer, improves light absorption and partially offsets thermal losses, allowing the panel to maintain steadier energy production on hot days compared to older non-PERC modules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Canadian_Solar-Datasheet-HiKu_CS3W-P_EN-f18249deadd8.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Goldi Solar GS10-B120-GF-455](https://comparepv.com/panel/goldi-solar-gs10-b120-gf-455) | 455 W | +40 W, cooler, +2.2 pp | | [Goldi Solar GS10-B120-GF-450](https://comparepv.com/panel/goldi-solar-gs10-b120-gf-450) | 450 W | +35 W, cooler, +2.0 pp | | [Goldi Solar GS10-B120-GF-445](https://comparepv.com/panel/goldi-solar-gs10-b120-gf-445) | 445 W | +30 W, cooler, +1.8 pp | | [Goldi Solar GS10-B120-GF-440](https://comparepv.com/panel/goldi-solar-gs10-b120-gf-440) | 440 W | +25 W, cooler, +1.5 pp | | [SunLink LNSU-410M](https://comparepv.com/panel/sunlink-lnsu-410m) | 410 W | +1.5 pp | | [Goldi Solar GS10-B120-GF-435](https://comparepv.com/panel/goldi-solar-gs10-b120-gf-435) | 435 W | +20 W, cooler, +1.3 pp | | [SunLink LNSU-405M](https://comparepv.com/panel/sunlink-lnsu-405m) | 405 W | -10 W, +1.3 pp | | [Canadian Solar CS3U-395P](https://comparepv.com/panel/canadian-solar-cs3u-395p) | 395 W | -20 W, lighter, +1.1 pp | | [SunLink LNSU-400M](https://comparepv.com/panel/sunlink-lnsu-400m) | 400 W | -15 W, +1.0 pp | | [Canadian Solar CS3W-395P](https://comparepv.com/panel/canadian-solar-cs3w-395p) | 395 W | -20 W, -0.9 pp | | [Canadian Solar CS3W-400P](https://comparepv.com/panel/canadian-solar-cs3w-400p) | 400 W | -15 W, -0.7 pp | | [Canadian Solar CS3W-405P](https://comparepv.com/panel/canadian-solar-cs3w-405p) | 405 W | -10 W, -0.5 pp | | [Canadian Solar CS3W-410P](https://comparepv.com/panel/canadian-solar-cs3w-410p) | 410 W | Very close match | | [Canadian Solar CS3W-420P](https://comparepv.com/panel/canadian-solar-cs3w-420p) | 420 W | Very close match | | [Canadian Solar CS3W-425P](https://comparepv.com/panel/canadian-solar-cs3w-425p) | 425 W | +10 W, +0.4 pp | | [Canadian Solar CS3W-430P](https://comparepv.com/panel/canadian-solar-cs3w-430p) | 430 W | +15 W, +0.7 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +175 W, cooler, +5.0 pp | --- Source: https://comparepv.com/panel/canadian-solar-cs3w-415p Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
