Solar Swiss

What Solar Swiss does

Solar Swiss GmbH is a German manufacturer of monocrystalline photovoltaic solar modules, founded in 2009 and headquartered in Reutlingen, Baden-Württemberg. The company produces a portfolio of solar modules in four form factors — framed (100W–220W), flexible (95W–125W), ultra-flat at 4mm thickness (100W–220W), and foldable/portable (100W–200W) — built around monocrystalline high-performance cells with reported efficiencies above 22%. Its products are bundled into complete solar kits (Komplettset) for motorhomes and boats, balcony power plants (Balkonkraftwerk) for residential use, and a full accessories line including charge controllers, cables, mounting hardware, and roof glands. The company also offers custom module manufacturing with a 5-week lead time and a repair/reproduction service for third-party modules.

The underlying technology relies on monocrystalline cell lamination in tempered glass or polymer substrates, integrated bypass diodes for partial shading tolerance, and compatibility with PWM and MPPT charge controllers. Modules carry IEC 61215, ISO 9001, and CE certifications, with a 20-year performance warranty covering 80% of minimum rated power. The business model is direct-to-consumer: customers select configurations on the company website and submit pricing inquiry forms (no public pricing or online checkout), with additional customer engagement via the CMT Stuttgart recreational vehicle trade show. Solar Swiss serves four primary use-case segments — RV owners (primary), marine/boat owners, balcony solar homeowners, and off-grid specialists — operating as a privately held, founder-run German GmbH with no external funding and no disclosed subsidiaries.

Core offering

Solar Swiss GmbH manufactures high-performance monocrystalline solar modules and complete solar power systems (kits) for recreational vehicles (motorhomes, campervans, caravans), boats, residential balcony power plants, and off-grid applications. Production occurs in-house at the Reutlingen, Baden-Württemberg facility, with modules offered in framed, flexible, ultra-flat (4mm), and foldable form factors ranging from 95W to 330W in 12V and 24V configurations, supplemented by solar charge controllers, mounting hardware, cables, roof penetrations, custom module manufacturing, and module repair/reproduction services.

Product overview

Solar Swiss GmbH is a German manufacturer of high-performance solar modules and complete solar systems based in Baden-Württemberg, operational since 2009. The product portfolio centers on four main solar module types: (1) Framed solar modules (KVM5/KVM6 series, 100W-220W) for motorhomes and off-grid applications; (2) Flexible solar modules (95W-125W) for curved surfaces; (3) Foldable solar modules/Solar bags (100W-200W) for portable/mobile use; and (4) Superflat solar modules (100W-220W, only 4mm thick) for low-profile mounting. These modules are complemented by complete solar kits, balcony power plants, and a comprehensive accessories line including charge controllers (Victron, Votronic, Steca), cables, mounting hardware, and roof passages. The company also offers custom manufacturing and repair/reproduction services for solar modules, serving both end consumers and commercial customers in the recreational vehicle, marine, and residential off-grid markets.

Emerging players

• Jackery: Global portable power and solar panel brand popular with camping/RV consumers — comparable foldable solar panel product and direct-to-consumer go-to-market, though primarily a power station vendor bundling solar rather than a module manufacturer.
• EcoFlow: Portable power station and foldable solar panel brand targeting camping, RV, and home backup — adjacent competitor for the foldable solar module category and the broader off-grid power kit customer.

Regional players

• Sunology: French plug-and-play balcony solar specialist offering monocrystalline balcony kits with microinverters — directly comparable to Solar Swiss's Balkonkraftwerk line, though operating primarily in France rather than Germany.

Direct peers

• Renogy: US-headquartered manufacturer and seller of solar panels, charge controllers, and complete off-grid kits specifically targeted at RVs, campervans, boats, and cabins — the same primary customer base as Solar Swiss, with overlapping monocrystalline rigid, flexible, and foldable form factors.
• Solar Technology International: UK-based specialist manufacturer of solar panels for motorhomes, boats, and off-grid leisure use — closely comparable niche focus, form factors, and complete-kit bundling strategy to Solar Swiss, though UK/European regional competitor.
• BougeRV: US/China-origin manufacturer and online retailer of rigid, flexible, and foldable solar panels plus complete RV kits — comparable product portfolio, target customer (RV/camping), and direct-to-consumer e-commerce model.
• Phaesun: German off-grid solar distributor and system integrator offering PV modules, charge controllers, and complete kits for mobile and remote applications — comparable product breadth and German/DACH customer base overlap with Solar Swiss.

Broad incumbents

• Solarwatt: Established German premium crystalline solar module manufacturer with full glass-glass residential and commercial lines — overlaps with Solar Swiss on 'Made in Germany' crystalline manufacturing heritage and quality positioning, but serves rooftop rather than mobile niche.
• SunPower: Premium US-headquartered crystalline solar module manufacturer with high-efficiency Maxeon cells — relevant comparable for high-efficiency monocrystalline technology positioning, though SunPower focuses on residential rooftop rather than mobile/RV applications.
