Thanks to the use of **Half-cut and Multi-busbar** construction, these modules offer significantly higher resistance to micro-cracks and better performance in partial shading conditions. This series solves the key problem of power loss on hot days by offering a low temperature coefficient, which translates into stable energy yields throughout the year. It is an ideal choice for investors seeking **maximum power density** on limited roof surfaces, both in residential installations and large commercial projects. What sets them apart from the competition is their exceptional mechanical durability and high-quality aesthetics, ensuring that Series 4 panels combine functionality with modern design. An innovative approach to production processes provides better absorption of diffuse radiation, making them extremely effective in the Polish climate with variable sunlight. By choosing this solution, the user gains **long-term energy stability** and the assurance that the system will maintain high efficiency even after many years of intensive use. It is a solid proposition for those who do not compromise on quality and are looking for premium-class components. ## Notable figures - Efficiency of 19.9% is 0.7pp below the \*\*PERC 400-450W\*\* median (20.6%) - At 198.7 W/m², this panel generates 7.5 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 26.0 kg (4.0 kg above \*\*PERC 400-450W\*\* median of 22.0 kg), requires checking roof load capacity - In the top 89% for efficiency among all PERC panels ## Questions ### What warranty does the Sunlike Solar Series 4 panel come with? The manufacturer provides a 12-year product warranty covering manufacturing defects and a 30-year linear power output warranty. After 30 years of operation, the panel should retain at least 80–87% of its rated capacity. This places Series 4 among the better-warranted modules on the market and secures the return on investment over several decades. ### Are Sunlike Solar Series 4 panels suitable for roofs with chimneys or dormers? Yes. The half-cut cell design splits each cell into two independent halves — if one section of the panel falls into shadow from a chimney, dormer, or antenna, the remaining sections continue operating at full power. This minimizes losses under partial shading, making Series 4 a reliable choice for complex roof layouts. ### What is the peak power of one Sunlike Solar Series 4 panel, and how many panels do I need for a single-family home? Each Series 4 module is rated at 455 Wp. For a typical household consuming around 4,000 kWh per year, 10–14 panels — a 4.5–6.5 kWp system — are usually sufficient. The exact count depends on roof orientation, tilt angle, and local solar irradiance. ### What is PERC technology and why was it chosen for the Series 4? PERC (Passivated Emitter and Rear Cell) is a monocrystalline cell technology featuring a passivation layer on the rear of the cell that reflects unabsorbed light back through the silicon for a second absorption pass. This gives Series 4 panels higher efficiency than standard BSF cells, better low-light performance, and lower degradation during the initial years of operation. ### How do Sunlike Solar Series 4 panels perform during hot summer days? High ambient temperatures reduce the output of any PV module — the lower the temperature coefficient, the smaller the power loss. The half-cut configuration reduces current per cell half, which lowers resistive losses at elevated temperatures. The result is more stable energy yield on hot summer days compared to conventional BSF modules. ### Are Sunlike Solar Series 4 panels compatible with popular inverters such as Fronius, SMA, or Huawei? Yes. As standard 455 Wp PERC modules with conventional voltage parameters and MC4 connectors, Series 4 panels are compatible with inverters from leading brands including Fronius, SMA, Huawei, SolarEdge, and Growatt. Before purchasing, verify the inverter's MPPT input voltage range to correctly size your string configuration. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/166-144CELL-430-450W-BIFACIAL-DG-99246ad9bbcb.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | Cooler, lighter, +4.4 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +50 W, cooler, +4.4 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, cooler, +4.4 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, cooler, +4.4 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +50 W, cooler, +4.4 pp | | [Sunlike Solar LNSU-430MD](https://comparepv.com/panel/sunlike-solar-lnsu-430md) | 430 W | -0.2 pp | | [Sunlike Solar LNSU-440MD](https://comparepv.com/panel/sunlike-solar-lnsu-440md) | 440 W | +0.2 pp | | [Sunlike Solar LNSU-445MD](https://comparepv.com/panel/sunlike-solar-lnsu-445md) | 445 W | +10 W, +0.5 pp | | [Sunlike Solar LNSU-450MD](https://comparepv.com/panel/sunlike-solar-lnsu-450md) | 450 W | +15 W, +0.7 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +155 W, cooler, +3.9 pp | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +150 W, cooler, +3.8 pp | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +145 W, cooler, +3.6 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +145 W, cooler, +3.6 pp | --- Source: https://comparepv.com/panel/sunlike-solar-lnsu-435md 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.
