Bifacial design captures additional rear-side irradiance — typically 5–15% extra yield in ground-mount systems with high-albedo surfaces — directly lowering the installation's LCOE. - **Factory-fitted Stäubli MC4 EVO2 connectors** - Decentralized junction boxes equipped with OEM Stäubli MC4 EVO2 connectors represent a premium BoS choice — full MC4 cross-compatibility, contact resistance \< 0.5 mΩ, which minimizes resistive losses and simplifies field servicing compared to generic connectors. - **Glass-glass build + IEC salt-mist & ammonia certification** - The dual-glass, anodized aluminum-framed construction has passed IEC 61701 (salt-mist) and IEC 62716 (ammonia) testing, confirming suitability for coastal and agricultural environments. Glass-glass laminates typically support a module service life exceeding 30 years and significantly reduce PID risk. - **European manufacturing since 1991** - KIOTO Solar has been operating out of Austria since 1991, offering European supply-chain traceability, no Asian-import tariff exposure (EU CBAM, anti-dumping duties), and over three decades of market presence as evidence of operational stability. - **Anti-reflective coating + ceramic rear-glass print** - The AR-coated front glass maximizes light transmission, while the partially ceramic-printed rear glass delivers a homogeneous visual appearance — a key differentiator for BIPV and commercial rooftop projects where aesthetics influence client and planning decisions. ## Cons - **Not on BNEF Tier-1 list** - KIOTO Solar does not appear on the Bloomberg NEF Tier-1 PV Module Manufacturer list, meaning the company has not documented independent commercial bank financing of at least six projects > 10 MW in the past two years. For utility-scale developers (> 1 MWp), this may complicate or block project debt financing without additional insurance or guarantees. - **Efficiency below top peer comparables** - The series tops out at 22.79% efficiency, while peer-comparable SunKean/Sunket SKT430~450M10-108D5 modules reach 23.04% at the same 450 Wp nameplate power. The ~0.25 pp gap equates to roughly 4.9 W/m² less output — a meaningful constraint for space-limited rooftop installations where every square centimeter drives total system capacity. ## About this series KIOTO Solar SOLAR-MODULE for Standard Applications 35 mm are **double-glass modules with an anodized aluminum frame**, designed for versatile applications - from standard roof installations to large-scale photovoltaic farms.

The modules have undergone rigorous tests for solar fog and ammonia, confirmed by IEC certifications, which guarantees long-term durability even in demanding climatic and environmental conditions. This series is dedicated to installers and developers seeking modules that combine high performance with elegant aesthetics and proven reliability. ## Notable figures - At 22.8% efficiency, this panel is 0.8pp above typical \*\*TOPCon 400-450W\*\* modules (median: 22.0%) - At 227.9 W/m² power density, this panel generates 7.7 W/m² more per unit area than \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 400-450W\*\* median - At 25.0 kg, this panel is 3.0 kg heavier than the \*\*TOPCon 400-450W\*\* median (22.0 kg) - more demanding for installation crews - Ranked #3005 out of 14005 panels for efficiency in the database ## Questions ### Does the bifacial TOPCon technology in the KIOTO Solar SOLAR-MODULE 35 mm series actually increase energy production? Yes. The half-cut TOPCon cells capture solar radiation from both the front and rear side of the module (albedo gain). The rear glass with partial ceramic print allows reflected light from the ground to contribute several additional percentage points of yield. The effect is most pronounced in ground-mounted systems with reflective substrates such as white gravel or snow cover. ### What warranty does the KIOTO Solar SOLAR-MODULE für Standardanwendungen 35 mm come with? The manufacturer provides a 15-year product warranty covering physical and material defects, and a 25-year linear power output warranty. The power warranty guarantees that over 25 years the module will maintain a minimum performance level relative to its rated output of 450 Wp. Before purchasing, confirm with the distributor who handles warranty service in your local market. ### Are KIOTO Solar SOLAR-MODULE 35 mm panels suitable for utility-scale solar farms? Yes, the series is engineered for large ground-mounted installations and solar farms. The bifacial double-glass design maximizes albedo yield, while the 450 Wp rated power keeps module count and BoS costs per kWp competitive. IEC-certified salt mist and ammonia resistance tests confirm long-term durability under demanding field and industrial environmental conditions. ### How do KIOTO Solar SOLAR-MODULE 35 mm panels perform under partial shading? The half-cut cell layout splits each cell into two halves, so shade on one portion of the module does not shut down the entire string. Decentralized junction boxes with genuine Stäubli MC4 EVO2 connectors further limit loss propagation between cell sections. This is a significant advantage for rooftop installations with chimneys or dormers as well as for solar farms with uneven horizon shading. ### Is KIOTO Solar a reliable manufacturer, and where is it headquartered? KIOTO Solar is a photovoltaic module manufacturer headquartered in Austria. The company is not listed in the BloombergNEF Tier 1 ranking; however, its panels carry IEC certifications including salt mist and ammonia resistance tests, confirming product quality. When purchasing, verify the availability of authorized warranty service in your market and ensure the distributor can supply documentation required by lenders or insurers. ### Are the Stäubli MC4 EVO2 connectors on KIOTO Solar SOLAR-MODULE 35 mm panels compatible with standard inverters and cables? Stäubli MC4 EVO2 connectors are one of the leading industry standards in PV installations, compatible with the vast majority of inverters and prefabricated solar cables on the market. The decentralized junction box design simplifies cable routing and future maintenance. When mating connectors from different manufacturers, always confirm electromechanical compatibility with your installer to maintain warranty validity. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Datenblatt-fuer-Standardanwendungen-SOLAR-MODULE-1153254bbb96.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, +2.0 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +45 W, +1.7 pp, +5 yr warranty | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +45 W, +1.7 pp, +5 yr warranty | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | Lighter, +1.5 pp, +5 yr warranty | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +40 W, +1.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +1.5 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +40 W, +1.5 pp, +5 yr warranty | | [KIOTO Solar KPV 440Wp HC NE (G/G-TC)](https://comparepv.com/panel/kioto-solar-kpv-440wp-hc-ne-g-g-tc) | 440 W | -0.3 pp | | [KIOTO Solar KPV 450Wp HC NE (G/G-TC)](https://comparepv.com/panel/kioto-solar-kpv-450wp-hc-ne-g-g-tc) | 450 W | -0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +65 W, cooler, +2.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +60 W, cooler, +1.9 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +55 W, cooler, +1.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +55 W, +1.7 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/kioto-solar-kpv-445wp-hc-ne-g-g-tc 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.
