ElectroFlex® Ultra-Thin Flexible Solar Measures 0.85mm with 24.4% PCE Cells, Built for OEM Production Line Integration
SCOTTSDALE, Ariz., Sept. 01, 2026 (GLOBE NEWSWIRE) — SolarWindow Technologies, Inc. (Symbol: WNDW), today released specifications for the Company’s ElectroFlex® product — ultra-thin, high-power, ‘peel-and-stick’ flexible solar, commercially launched last week.
CEO Amit Singh Demonstrates
ElectroFlex® Ultra-Thin Flexible Solar
For OEM manufacturers, ElectroFlex® transforms passive surface areas that are otherwise dead weight into active sources of onboard power, extending range and reducing generator, shore-power, and grid dependence.
Thinner than a dime, ElectroFlex® measures 0.85 millimeters, and is available in sheets up to 22 square feet, as large as a standard pool table. ElectroFlex® is up to 40 times thinner and generates up to 7.5 times more power than a traditional solar panel (watts per pound). Standard ElectroFlex® sheets weigh as little as 3.2 ounces per square foot.
ElectroFlex® is built on high-efficiency interdigitated back-contact monocrystalline silicon cells rated at up to 24.4% power conversion efficiency. Because the cells carry no front-side busbars, ElectroFlex® is able to wrap around the contour of a surface without the micro-cracking that fractures conventional cell interconnects. ElectroFlex® generates electricity on curved and flat surfaces traditional solar could never reach.
ElectroFlex® is configured to the customer’s exact product specifications, including dimensions, geometry, mounting, power, and color requirements. There are no standard panels sizes or configurations.
Seamless Flush-Mount PV. Built for OEM Integration
ElectroFlex® offers Tier-1 OEM partners (original equipment manufacturers which build vehicles, buildings, and devices) a seamless flush-mount solar system with no racks to engineer, no structures to reinforce, and no penetrations to seal.
ElectroFlex® is ultra-thin, light, and flexible, and bonds directly to the product on the manufacturer’s own production line in one single step. Conversely, traditional solar panel mounting requires multiple steps, and inefficient, costly, with staggered installation.
Unlike ElectroFlex®, traditional solar requires aluminum frames, mounting racks, roof penetrations, structural reinforcements or supports to carry the load, freight shipping for heavy palletized goods, and heavy lifting equipment. ElectroFlex® eliminates these categories of cost for OEMs and their customers.
Integrated Into the Production Line, Not Bolted on Afterward
ElectroFlex® is applied by the manufacturer on its own production line as part of assembly. There is no separate installation event, no crew scheduled after the product is built, and no second handling of a finished unit.
For qualified OEMs, SolarWindow will engineer, design, and model the energy system for each product application. SolarWindow supplies all wiring, harnessing, electrical systems balancing, and power delivery. SolarWindow then develops the application process for that specific product, adapts it to the manufacturer’s existing line, and trains the manufacturer’s own personnel to apply ElectroFlex® in production.
Availability
ElectroFlex® is initially available exclusively to America’s Tier-1 OEM manufacturers, expanding to select North American and Asian markets in the upcoming quarters. ElectroFlex® is targeting transportation, marine, aerospace, architectural, agricultural, infrastructure and utilities, and specialty vehicle markets.
Tier-1 OEM manufacturers evaluating ElectroFlex® for their own applications can request specifications, samples, and integration support via the Company’s website at www.solarwindow.com or by calling +1 (800) 213-0689.
A New SolarWindow
Alongside the ElectroFlex® launch, SolarWindow unveiled a completely redesigned website at www.solarwindow.com. The new site reflects the Company’s evolution from a single-technology developer into an energy technology platform with a portfolio of products, and gives a clear view of each product line, its stage of development, and its market applications.
Interested parties are encouraged to visit www.solarwindow.com to explore ElectroFlex® and the SolarWindow product portfolio.
