The panel measures 153 × 73 mm overall and includes a centered 45 × 30 mm semicircular cutout, allowing a product design to preserve space around a central component or access opening. SPIC back-contact solar cells are SMT-mounted to the PCB, with two polarity-marked solder pads on the rear.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1W at 18V:\u003c\/strong\u003e Provides a compact solar input for low-power electronics and energy-harvesting systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSemicircular ring shape:\u003c\/strong\u003e Fits special-shaped layouts that cannot use a conventional rectangular panel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDefined center opening:\u003c\/strong\u003e The 45 × 30 mm cutout leaves clearance for a central component, fixture, or enclosure feature.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable ETFE surface:\u003c\/strong\u003e Waterproof, UV-resistant, and scratch-resistant construction supports outdoor product integration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack-contact SMT construction:\u003c\/strong\u003e SPIC solar cells are mounted to the PCB while electrical contacts remain on the rear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM-ready format:\u003c\/strong\u003e Contact LinkSolar about custom dimensions, outlines, lead wires, or connectors for production projects.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBest For\u003c\/h3\u003e\n\u003cp\u003eA practical choice for custom enclosures, compact sensor assemblies, monitoring equipment, and OEM products that require solar collection around a central opening or component.\u003c\/p\u003e\n\u003ch3\u003eDetails \u0026amp; Specs\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated maximum power\u003c\/td\u003e\n\u003ctd\u003e1 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated voltage\u003c\/td\u003e\n\u003ctd\u003e18 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverall dimensions\u003c\/td\u003e\n\u003ctd\u003e153 × 73 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShape\u003c\/td\u003e\n\u003ctd\u003eSemicircular ring \/ half-ring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCenter cutout\u003c\/td\u003e\n\u003ctd\u003e45 × 30 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSurface\u003c\/td\u003e\n\u003ctd\u003eWaterproof, UV- and scratch-resistant ETFE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell and build\u003c\/td\u003e\n\u003ctd\u003eSPIC back-contact cells, SMT-mounted to PCB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection\u003c\/td\u003e\n\u003ctd\u003e2 polarity-marked rear copper solder pads\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSingle-panel net weight\u003c\/td\u003e\n\u003ctd\u003eApproximately 18 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eCompatibility \u0026amp; Notes\u003c\/h3\u003e\n\u003cp\u003eCheck the 45 × 30 mm center opening against the intended enclosure or component before ordering. Use a charge controller or regulator suited to the connected device or battery; do not assume direct compatibility from the 18V rating alone. Output varies with sunlight intensity, angle, temperature, controller, battery, and overall system setup. Waterproof construction does not assign a specific IP rating or imply suitability for submersion. Protect the exposed PCB and solder pads from mechanical impact and excessive vibration in the finished assembly.\u003c\/p\u003e\n\u003cp\u003eNeed a different footprint or termination? \u003ca href=\"\/pages\/contact\"\u003eContact LinkSolar\u003c\/a\u003e about custom panel dimensions, outlines, lead wires, or connectors.\u003c\/p\u003e","brand":"LinkSolar","offers":[{"title":"1PCS","offer_id":45152960708808,"sku":"LS-MSP-S209","price":13.09,"currency_code":"USD","in_stock":true},{"title":"5PCS","offer_id":45152960741576,"sku":"LS-MSP-S209-05","price":42.79,"currency_code":"USD","in_stock":true},{"title":"10PCS","offer_id":45152960774344,"sku":"LS-MSP-S209-10","price":76.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0685\/7582\/2024\/files\/1w-18v-semicircular-solar-panel-front-01.png?v=1785306647","url":"https:\/\/linksolar.net\/products\/mini-solar-panel-1w-18v-semicircular","provider":"LinkSolar","version":"1.0","type":"link"}
