Cando Solar Cloth: A Breakthrough in Lightweight Solar Technology

Cando Solar, a leader in the lightweight solar energy field, has recently launched its innovative rollable crystalline silicon heterojunction (HJT) solar wing solution, known as the Cando Solar Cloth. This exciting development was revealed at the SATELLITE × GovMilSpace event in Washington, D.C. on March 24, 2026. The Cando Solar Cloth aims to transform commercial satellite functionality through advanced solar technology tailored for low Earth orbit (LEO) operations, 6G communications, and various space computing power applications.

Revolutionizing Energy Solutions for Space

Traditionally, satellite solutions have struggled with weight and cost constraints due to the bulkiness and expense of rigid solar arrays. However, Cando Solar’s new product marks a paradigm shift from prioritizing area efficiency to focusing on weight efficiency. This innovative approach unlocks the potential for abundant energy in space, thereby enhancing power equity on Earth.

As the commercial space industry expands rapidly with frequent satellite launches and the deployment of satellite constellations, there is a pressing need for lightweight, cost-effective solutions. Cando Solar's rollable HJT solar wing solution directly addresses these challenges with a design that utilizes cutting-edge engineering technologies.

Lightweight and Efficient Design

The Cando Solar Cloth boasts an impressive weight-to-area ratio ranging between 300–900 g/m², with a compact rolled diameter of only 65 mm. This ultra-lightweight design significantly reduces launch volumes and minimizes payload requirements. The weight-to-power ratio is even more remarkable, scaling between 1–5 g/W, facilitating an overall reduction in satellite mass while ensuring efficiency in energy generation.

Cost-Effective Solar Conversion

When compared to conventional GaAs solar cells, Cando Solar Cloth sets a new industry standard with a conversion efficiency between 23–35% (and up to 35% with tandem HJT cells), while also slashing costs by a staggering 90%. This extraordinary efficiency allows for shared production capabilities not only in space but also in terrestrial applications, such as agriculture, construction, and transportation. Consequently, it can lower overall satellite manufacturing expenses by up to 30%, dismantling a significant barrier to large-scale deployment of satellite constellations.

Proven Reliability

Cando Solar Cloth's durability is at the forefront of its design, having undergone rigorous electroluminescence (EL) testing after 10,000 roll-and-unroll cycles. This ensures a reliable energy output during its operational lifespan in orbit, an essential feature for any satellite technology.

Strategic Future Directions

Huang Qiang, the founder of Cando Solar, emphasized the importance of their presentation at the SATELLITE × GovMilSpace event, stating, “It not only showcases our capabilities in space energy but also marks a crucial step in our global expansion strategy. We aim to advance the adoption of lightweight solar technologies, making affordable, efficient clean energy a cornerstone for humanity's endeavors beyond our planet.”

In conclusion, the introduction of Cando Solar Cloth signifies a leap forward in solar technology, opening doors for innovative solutions in both space and terrestrial contexts. With its lightweight design, cost-saving potential, and high reliability, Cando Solar is set to lead the charge in evolving how we generate and utilize solar energy.
