The Helios Captures It.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eConventional solar panels are designed for one surface: the front. Light that passes through the gaps in a ground-mount array, reflects off a white rooftop, or diffuses through morning haze strikes the opaque backsheet and dissipates as heat. The Helios Bifacial replaces that backsheet with a transparent laminate and a secondary photovoltaic layer — effectively turning the panel into a two-sided energy harvester. In real-world deployment, the rear face contributes an additional 15-25% output depending on albedo — the reflectivity of the surface beneath it. On a white gravel bed, snow cover, or a light-colored rooftop, that bonus is material.\u003c\/p\u003e\n\u003cp\u003eBuilt on monocrystalline silicon cells with half-cut architecture, the Helios reduces resistive losses by splitting each cell into two smaller current paths. The result is higher efficiency under partial shading — when a branch or chimney shadow falls across a single cell, only that half-cell's output is affected rather than an entire string. At 100 watts nominal and 12 volts output, it slots into existing off-grid, RV, marine, and residential systems without a controller upgrade. The bifacial gain is not a marketing headline. It is a physics reality that compounds over the 25-year service life of the module.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #eee;\"\u003e\n\u003cdiv class=\"product-features\"\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul style=\"list-style: none; padding: 0;\"\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #f0f0f0;\"\u003e✦ \u003cstrong\u003eBifacial Energy Harvesting\u003c\/strong\u003e — Transparent backsheet with secondary photovoltaic layer captures reflected and diffuse light from the rear surface, delivering 15-25% additional output in typical ground-mount or light-roof installations.\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #f0f0f0;\"\u003e✦ \u003cstrong\u003eHalf-Cut Monocrystalline Cells\u003c\/strong\u003e — Each cell is split into two electrically independent halves, reducing series resistance losses and improving performance under partial shading conditions that would cripple a full-cell panel.\u003c\/li\u003e\n\u003cli style=\"padding: 8px 0; border-bottom: 1px solid #f0f0f0;\"\u003e✦ \u003cstrong\u003e100W Rated Output at 12V\u003c\/strong\u003e — Compatible with standard PWM and MPPT charge controllers.

Off-grid cabins with white metal roofing see 20-25% bifacial gain from roof-reflected light — effectively turning a 100W panel into a 120-125W panel at zero additional footprint. RV and campervan rooftop arrays on light-colored vehicle roofs capture diffuse light bouncing off the roof surface. Ground-mount arrays on snow-covered terrain, white gravel, or light-colored sand benefit from high-albedo reflection throughout the winter months when solar hours are most precious. Marine installations on white fiberglass decks harvest reflected light from both the deck surface and water — a compounding effect that makes bifacial panels the default choice for liveaboard vessels and remote monitoring stations. For grid-tied residential systems, the Helios integrates into any string that accepts 100W 12V modules, adding bifacial capacity without requiring a microinverter swap.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-faq\"\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdiv style=\"margin-bottom: 15px;\"\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How much extra power does the bifacial design actually produce?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The rear-side contribution depends entirely on albedo — the reflectivity of the surface beneath the panel. On dark soil or asphalt, expect 5-10% gain. On white gravel, light concrete, or snow, expect 15-25%. On a white-painted rooftop with a 4-inch mounting gap for airflow, real-world measurements show 18-22% improvement over an equivalent monofacial panel in the same orientation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 15px;\"\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need a special charge controller for a bifacial panel?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: No. The Helios outputs standard 12V DC through MC4 connectors — compatible with any PWM or MPPT charge controller rated for 100W+ at 12V. The bifacial gain manifests as higher current under given irradiance; a quality MPPT controller will track the maximum power point automatically as the rear face contributes additional current.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 15px;\"\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will half-cut cells really make a difference in partial shade?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes — and the difference is structural, not incremental. In a full-cell panel, a shadow across one cell reduces the entire string's output because current must flow through the shaded cell. In a half-cut panel, each cell is split into two independent current paths. A shadow on one half-cell only blocks that half — the other half continues producing. In arrays where morning or late-afternoon shadows are unavoidable (trees, chimneys, neighboring structures), half-cut architecture can recover 10-30% of production that a full-cell panel would lose.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 15px;\"\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I mount this panel flush to a dark roof?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: You can, but the bifacial gain will be minimal — the rear face needs a reflective surface and an air gap to capture reflected light. For flush-mount on dark shingles, a monofacial panel is more cost-effective. For installations with a 3-6 inch standoff above a light-colored surface, the bifacial premium pays for itself within the first 2-3 years of operation through additional energy harvest.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 15px;\"\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I connect multiple Helios panels together?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: MC4 connectors support both series (voltage additive) and parallel (current additive) wiring. For a 12V system, wire in parallel to maintain 12V while increasing current capacity. For 24V or 48V systems, wire 2 or 4 panels in series respectively. Always match panel specifications within a series string — do not mix bifacial and monofacial panels in the same series circuit.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-gallery\" style=\"margin-top: 30px; text-align: center;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/Sdc287e405d5a4a0ab2008862db3c7e00S.webp?v=1784074516\" style=\"max-width:100%;margin:5px 0;\" alt=\"Product image\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/Sc2e22fae9a3a469abe1a2fd0024d97b4u.webp?v=1784074516\" style=\"max-width:100%;margin:5px 0;\" alt=\"Product image\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/S058299165d364e88a4e1e8ecd2622be64.webp?v=1784074516\" style=\"max-width:100%;margin:5px 0;\" alt=\"Product image\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/S8324027342404b50b7c6378b58a4107ay.webp?v=1784074516\" style=\"max-width:100%;margin:5px 0;\" alt=\"Product image\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/Sf04aa9f810764af3b83b721cff2720d3j.webp?v=1784074516\" style=\"max-width:100%;margin:5px 0;\" alt=\"Product image\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/Sb0a433b069a04cbeb84a6b8347705c13H.webp?v=1784074516\" style=\"max-width:100%;margin:5px 0;\" alt=\"Product image\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/4f98df51dc40d0cd.jpg?v=1784074516\" style=\"max-width:100%;margin:5px 0;\" alt=\"Product image\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/93b141fd145f29ea.jpg?v=1784074516\" style=\"max-width:100%;margin:5px 0;\" alt=\"Product image\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/89c6564986090bc3.jpg?v=1784074516\" style=\"max-width:100%;margin:5px 0;\" alt=\"Product image\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/3fe97eedfe890f43.jpg?v=1784074516\" style=\"max-width:100%;margin:5px 0;\" alt=\"Product image\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/a61469e17a942f98.jpg?v=1784074516\" style=\"max-width:100%;margin:5px 0;\" alt=\"Product image\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/8c8538c19989455c.jpg?v=1784074516\" style=\"max-width:100%;margin:5px 0;\" alt=\"Product image\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/78438dc9109d8c36.jpg?v=1784074516\" style=\"max-width:100%;margin:5px 0;\" alt=\"Product image\"\u003e\n\u003c\/div\u003e\u003cscript type=\"application\/ld+json\"\u003e\n{\"@context\":\"https:\/\/schema.org\",\"@type\":\"Product\",\"name\":\"The Helios Bifacial | 100W Monocrystalline Dual-Sided Solar Module\",\"description\":\"Bifacial 100W 12V monocrystalline solar panel with half-cut cells for enhanced partial-shade performance and rear-side energy harvesting.\",\"sku\":\"HELIOS-BIFACIAL-100W\",\"brand\":{\"@type\":\"Brand\",\"name\":\"ECO-WORTHY\"},\"image\":\"https:\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/Sdc287e405d5a4a0ab2008862db3c7e00S.webp?v=1784074516\",\"offers\":{\"@type\":\"Offer\",\"url\":\"https:\/\/eastsupplier.com\/products\/the-helios-bifacial-100w-solar-panel\",\"priceCurrency\":\"USD\",\"price\":\"125.21\",\"availability\":\"https:\/\/schema.org\/InStock\",\"priceValidUntil\":\"2027-07-15\"},\"aggregateRating\":{\"@type\":\"AggregateRating\",\"ratingValue\":\"4.8\",\"reviewCount\":\"9\",\"bestRating\":\"5\"}}\n\u003c\/script\u003e","brand":"EastSupplier Platform","offers":[{"title":"black \/ United States","offer_id":50570060202207,"sku":"1005010027250225-black-United States","price":143.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0503\/6412\/1244\/files\/Sdc287e405d5a4a0ab2008862db3c7e00S.webp?v=1784074516","url":"https:\/\/eastsupplier.com\/ja-pt\/products\/the-helios-bifacial-100w-solar-panel","provider":"EastSupplier Platform","version":"1.0","type":"link"}
