Thanks to **bifacial technology**, an installation can harvest additional energy reflected from the ground, making it especially attractive for solar farms, industrial rooftops with light-colored surfaces, and elevated ground-mount structures where ambient albedo favors light reflection. The use of **half-cut cells** reduces resistive losses and improves partial shading tolerance, while the multi-busbar (MBB) structure increases the reliability of electrical connections and lowers the risk of micro-cracks. The modules stand out for their **low temperature coefficient**, allowing them to maintain performance even in the high ambient temperatures typical of large summer ground-mount installations. The manufacturer has also minimized light- and temperature-induced degradation (LID/LeTID), resulting in more stable energy production throughout the module's lifetime. The BiHiKu series works well in both commercial and industrial projects, where long-term profitability (lower LCOE) and solid **product and power warranties** confirming investment durability matter most. ## Notable figures - Module efficiency of 18.3% is 2.3pp below average for \*\*PERC 400-450W\*\* panels (median: 20.6%) - At 183.5 W/m², this panel generates 22.7 W/m² less per unit area than \*\*PERC 400-450W\*\* median (206.2 W/m²) - Temperature coefficient of -0.36%/°C matches the \*\*PERC 400-450W\*\* median - At 28.4 kg, this panel is 6.4 kg heavier than the \*\*PERC 400-450W\*\* median (22.0 kg) - more demanding for installation crews - 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces ## Questions ### Is the Canadian Solar BiHiKu series still available for purchase? The BiHiKu series has been discontinued from current production by Canadian Solar and replaced by newer models featuring TOPCon technology and later bifacial generations (e.g., BiHiKu7). Panels from this series may still be available through distributors' remaining stock or the secondary market, but buyers should check the production date and warranty validity before purchasing. ### How much extra energy does the bifacial design of BiHiKu modules provide? Thanks to bifacial technology, BiHiKu modules capture reflected radiation on the rear side, typically delivering an additional yield of a few percent up to 20-25%, depending on ground albedo, mounting height, and tilt angle. Best results are achieved on bright surfaces like gravel, white industrial roofs, or snow, which is why this series is mainly suited to PV farms and elevated ground-mount structures. ### What warranty comes with Canadian Solar BiHiKu panels? The manufacturer provides a 12-year product warranty and a 30-year linear power output warranty. This means the panel should still retain a significant portion of its rated output after that period, making it a solid long-term investment for commercial and industrial installations. ### How do half-cut cells in BiHiKu differ from standard full-size cells? Half-cut cells are PERC cells cut in half, which reduces resistive losses and the current flowing through each path, lowering power loss. They also improve tolerance to partial shading - if part of the panel is shaded, the rest of the module can still operate efficiently, resulting in higher and more stable energy production under real-world conditions. ### Are 445 Wp BiHiKu panels suitable for large ground-mount installations? Yes, up to 445 Wp output combined with a low temperature coefficient means BiHiKu modules perform well under the high temperatures typical of summer at solar farms. The bifacial design further boosts energy yield on elevated ground-mount structures where the rear side has good access to reflected light, helping lower the project's LCOE. ### Is Canadian Solar a Tier 1 manufacturer, and what does that mean for buyers? Yes, Canadian Solar is classified as a Tier 1 manufacturer, indicating financial stability, large-scale production, and a proven track record of warranty reliability worldwide. For buyers, this reduces the risk of issues with future warranty claims and makes it easier to secure bank financing for projects using these modules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Canadian_Solar-Datasheet-BiHiKu_CS3W-PB-AG_EN-810e5f3bcd57.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 | +45 W, +2.7 pp, -5 yr warranty | | [Goldi Solar GS10-B120-GF-450](https://comparepv.com/panel/goldi-solar-gs10-b120-gf-450) | 450 W | Lighter, +2.5 pp, -5 yr warranty | | [Goldi Solar GS10-B120-GF-445](https://comparepv.com/panel/goldi-solar-gs10-b120-gf-445) | 445 W | Lighter, +2.3 pp, -5 yr warranty | | [Goldi Solar GS10-B120-GF-440](https://comparepv.com/panel/goldi-solar-gs10-b120-gf-440) | 440 W | Lighter, +2.0 pp, -5 yr warranty | | [SunLink LNSU-410M](https://comparepv.com/panel/sunlink-lnsu-410m) | 410 W | Lighter, +2.0 pp, -5 yr warranty | | [Goldi Solar GS10-B120-GF-435](https://comparepv.com/panel/goldi-solar-gs10-b120-gf-435) | 435 W | Lighter, +1.8 pp, -5 yr warranty | | [SunLink LNSU-405M](https://comparepv.com/panel/sunlink-lnsu-405m) | 405 W | Lighter, +1.8 pp, -5 yr warranty | | [Canadian Solar CS3U-395P](https://comparepv.com/panel/canadian-solar-cs3u-395p) | 395 W | Lighter, +1.6 pp, -5 yr warranty | | [SunLink LNSU-400M](https://comparepv.com/panel/sunlink-lnsu-400m) | 400 W | Lighter, +1.5 pp, -5 yr warranty | | [Canadian Solar CS3W-390PB-AG](https://comparepv.com/panel/canadian-solar-cs3w-390pb-ag) | 390 W | -20 W, -0.8 pp | | [Canadian Solar CS3W-395PB-AG](https://comparepv.com/panel/canadian-solar-cs3w-395pb-ag) | 395 W | -15 W, -0.6 pp | | [Canadian Solar CS3W-400PB-AG](https://comparepv.com/panel/canadian-solar-cs3w-400pb-ag) | 400 W | -10 W, -0.4 pp | | [Canadian Solar CS3W-405PB-AG](https://comparepv.com/panel/canadian-solar-cs3w-405pb-ag) | 405 W | Very close match | | [Canadian Solar CS3W-415PB-AG](https://comparepv.com/panel/canadian-solar-cs3w-415pb-ag) | 415 W | Hotter, +0.3 pp | | [Canadian Solar CS3W-420MB-AG](https://comparepv.com/panel/canadian-solar-cs3w-420mb-ag) | 420 W | +10 W, cooler, +0.5 pp | | [Canadian Solar CS3W-425PB-AG](https://comparepv.com/panel/canadian-solar-cs3w-425pb-ag) | 425 W | +15 W, hotter, +0.7 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +180 W, cooler, +5.5 pp | --- Source: https://comparepv.com/panel/canadian-solar-cs3w-410pb-ag Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
