Man shares how he built a 100% solar drone that can fly for hours and hours
When a YouTuber decided to build a 100 percent solar drone, he wanted to make sure it could both fly properly and fly for as long as possible.
Most drones run out of juice fast unless they land for a recharge, but this one was designed to stay in the air using nothing but sunlight.
After an earlier version barely managed a few minutes before crashing, its creator went back to the drawing board to build something far more capable.
What followed was a long process of rebuilding, testing, tweaking, and finally proving that a solar drone really could keep going for hours.

Man shares how he built a 100% solar drone
This ambitious tech project started with a major redesign after the first version ran into some very obvious problems.
The original solar panels were fragile, cracked easily, and did not mount well to the frame, so the YouTuber, Luke, had to come up with a sturdier setup.
He created new sleeves and supports for the carbon fiber arms, shortened the drone’s frame to make it lighter and more agile, and shaved off valuable weight in the process.
He then built a huge solar array made up of dozens of panels wired together, creating what looked almost like a flying patchwork of solar cells.
After checking the power output in full sun, he found the setup could produce more than enough energy to keep the drone hovering, at least in theory.
That was the exciting part; the nerve-racking bit was seeing whether it could actually survive in the real world.
He finally managed to pull off the ambitious project
The first real solar-only flight did not exactly go to plan.
A sudden power drop caused the drone to come down after just a few minutes, making it clear that even a solar drone needed a little help when conditions changed.
To solve that, he added a backup battery system that would quietly take over whenever the solar power dipped, then recharge once the sun came back strong.
That proved to be the game-changer.
After more tweaks to improve stability, reduce wobble, and deal with wind, the drone was tested again in calmer conditions.
This time it kept flying past 20 minutes, then one hour, then two, and then beyond three and a half hours.
In the end, the drone stayed in the air for more than five hours, powered by the sun and some very smart engineering.
For a homemade project that once crashed after three minutes, that is seriously impressive.
