Unlike standard products available on the market, this series utilizes a patented, solid copper cell foundation, which provides **exceptional resistance to corrosion** and micro-cracks resulting from natural mechanical stress. The innovative design, free of front-side conductive tracks, allows for maximum use of incoming light while eliminating the risk of harmful hot spots. It is an ideal choice for the most demanding users looking for power on **curved surfaces**, such as the roofs of modern motorhomes, caravans, or yacht decks, where traditional, heavy panels in rigid frames cannot be installed. Thanks to the unique ability to bend up to 30 degrees and very low weight, SPR-E-Flex modules guarantee **maximum mobility and ease of installation** without the need for interference with the vehicle or boat hull structure. Choosing this series effectively solves the problem of limited installation space and difficult weather conditions, offering stable and trouble-free operation even in aggressive marine environments. It is currently the **highest efficiency in the flexible segment**, which significantly outperforms the competition in terms of longevity and real energy yields per square meter of surface area. ## Notable figures - At 17.0% efficiency, this panel is 1.8pp below the \*\*Flexible 0-400W\*\* median of 18.8% - Power density of 169.8 W/m² is 19.9 W/m² below \*\*Flexible 0-400W\*\* median (189.7 W/m²) - needs more roof space - At -0.30%/°C (vs median -0.35%/°C), loses ~2% less power in hot conditions - Weight of 2.0 kg (1.6 kg below \*\*Flexible 0-400W\*\* median of 3.6 kg) allows easier transport and roof mounting - In the top 96% for efficiency among all Flexible panels ## Questions ### What curved surfaces are the Maxeon SPR-E-Flex panels compatible with? The SPR-E-Flex series supports a maximum bend angle of 30 degrees in any direction, making it ideal for RV and camper roofs, caravan tops, and boat or yacht decks where rigid, aluminum-framed modules cannot be installed. The 110 W model weighs approximately 2 kg (dimensions 1165 × 569 mm), so the panel adds virtually no structural load to the vehicle body or hull. ### What efficiency do the Maxeon IBC cells in the SPR-E-Flex series achieve, and how do they differ from standard flexible panel cells? The SPR-E-Flex uses second-generation Maxeon IBC back-contact cells rated at 22–25% efficiency — the highest available in the flexible solar panel segment. The back-contact design eliminates front busbars entirely, so the full cell surface captures light without electrode-shading losses. The copper cell foundation prevents micro-cracking during repeated flexing, a common failure mode in cheaper amorphous silicon or CIGS-based flexible modules. ### What warranty does the Maxeon SPR-E-Flex 110W carry? Maxeon provides a 5-year product warranty covering defects in materials and workmanship, alongside a 5-year power output warranty guaranteeing at least 80% of rated peak power over that period. For the flexible panel segment these are competitive terms, though Maxeon's rigid panel lines such as Air and Neo carry 25–40-year warranties — the shorter coverage here reflects the more demanding operating environment of flexible modules. ### Is the Maxeon SPR-E-Flex series still available for purchase? The SPR-E-Flex series, including the 110 W model, has been officially discontinued by Maxeon. Availability through distribution channels is limited to remaining warehouse stock, which may already be largely depleted. If you require a flexible IBC-technology module, we recommend checking Maxeon's current product lineup or comparing offerings from other manufacturers specializing in semi-flex or fully flexible PV modules. ### Can the SPR-E-Flex panel handle marine environments — salt water, humidity, and UV exposure? Yes, the SPR-E-Flex was specifically engineered for harsh marine conditions. The junction box carries an IP67 ingress protection rating, and the encapsulation is both UV-resistant and salt-spray resistant. The copper-backed Maxeon IBC cell foundation delivers superior corrosion resistance compared to aluminum-based cells used in lower-cost competing products — a critical advantage for equipment permanently exposed to offshore or sailing environments. ### How do you install a Maxeon SPR-E-Flex 110W on an RV roof — do you need rails or drilling? No drilling or aluminum rail systems are required. The flexible construction and ultra-low weight of approximately 2 kg allow non-invasive adhesive mounting using marine-grade double-sided tape or a dedicated bonding adhesive suited for RV and boat applications. The panel ships with MC4-compatible connectors and 4 mm² cables, making integration straightforward with standard off-grid systems and MPPT charge controllers. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/sp-E-Flex-110W-UK-62bb7831f188.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Gamko New Energy GKA182M150W](https://comparepv.com/panel/gamko-new-energy-gka182m150w) | 150 W | Heavier, +6.0 pp, +25 yr warranty | | [Gamko New Energy GKA182M160W](https://comparepv.com/panel/gamko-new-energy-gka182m160w) | 160 W | Heavier, +6.0 pp, +25 yr warranty | | [Gamko New Energy GKA182M120W](https://comparepv.com/panel/gamko-new-energy-gka182m120w) | 120 W | Heavier, +6.0 pp, +25 yr warranty | | [Gamko New Energy GKA182M135W](https://comparepv.com/panel/gamko-new-energy-gka182m135w) | 135 W | Heavier, +6.0 pp, +25 yr warranty | | [Gamko New Energy GKA182M100W](https://comparepv.com/panel/gamko-new-energy-gka182m100w) | 100 W | Heavier, +6.0 pp, +25 yr warranty | | [Gamko New Energy GKA182M110W](https://comparepv.com/panel/gamko-new-energy-gka182m110w) | 110 W | Heavier, +6.0 pp, +25 yr warranty | | [JA Solar NS-100MH-36](https://comparepv.com/panel/ja-solar-ns-100mh-36) | 100 W | Heavier, +4.3 pp, +20 yr warranty | | [PolyCrown Solar Tech NS-100MH-36](https://comparepv.com/panel/polycrown-solar-tech-ns-100mh-36) | 100 W | Heavier, +4.3 pp, +20 yr warranty | | [Renesola YH120W-18M](https://comparepv.com/panel/renesola-yh120w-18m) | 120 W | Hotter, +2.6 pp, +25 yr warranty | | [Easun Power YH100W-12M](https://comparepv.com/panel/easun-power-yh100w-12m) | 100 W | -10 W, hotter, +2.6 pp | | [Maxeon SPR-E-Flex-100](https://comparepv.com/panel/maxeon-spr-e-flex-100) | 100 W | -10 W, -1.6 pp | | [Sunman SMF100F-3X12UW](https://comparepv.com/panel/sunman-smf100f-3x12uw) | 100 W | -10 W, -1.3 pp | | [TPL Solar TPL100S-36](https://comparepv.com/panel/tpl-solar-tpl100s-36) | 100 W | Hotter, -1.3 pp, +25 yr warranty | | [TPL Solar TPL95S-36](https://comparepv.com/panel/tpl-solar-tpl95s-36) | 95 W | Hotter, -1.6 pp, +25 yr warranty | | [TPL Solar TPL90S-36](https://comparepv.com/panel/tpl-solar-tpl90s-36) | 90 W | Hotter, -1.9 pp, +25 yr warranty | | [TPL Solar TPL85S-36](https://comparepv.com/panel/tpl-solar-tpl85s-36) | 85 W | Hotter, -2.2 pp, +25 yr warranty | --- Source: https://comparepv.com/panel/maxeon-spr-e-flex-110 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
