Using solar power and water from atmospheric moisture to perform electrolysis, could you theoretically generate enough hydrogen to counteract leakage over time in an airship?

So given a ballpark estimate of the mass of those machines, and the requisite volume of hydrogen required to lift that load, and using solar panels on the portions of the surface area of the airship that will be in sunlight, and moisture collectors to gather water from the air, could such an arrangement absorb enough water and electricity each day to generate enough hydrogen to offset the loss that would occur due to natural leakage?

Napkin calculations...

One panel at 0.2kW can generate 357BTU of hydrogen per hour. Converted to cubic feet that is 1.32cu ft. and in weight is 0.09lbs of lift.

Loss of modern airships is only about 0.5-1% per day. Loss attributed to a panel would be at least 18 lbs of lift.

A 0.20 kW panels weighs about 25 lbs. So, it can not even keep itself in the air let alone the rest of the equipment and the ship.
