Team and vision

Open up new horizons

XSun is exploring the future with energy-independent drones that can make their own decisions

Passionate about science and technology, we are always looking for new and innovative solutions.

Promoting the incredible potential of solar power, an inexhaustible and free energy source, is one of the founding pillars of XSun. The successful marriage between new technologies and renewable energies (such a solar power) provides a whole host of solutions. SolarXOne, the 1st drone model designed and manufactured by XSun, is a product of this marriage.
