Solar hydrogen panels are also known as synthetic photosynthesis and produce hydrogen from the sun and water vapors straight away. The devices are called solar water-splitting systems. Designed to use sunlight to produce hydrogen gas directly through the technique of photovoltaic electrolysis, these systems could be made up of any combination including photovoltaic cells that convert sunlight into electricity, plus electrolyzers that split water into hydrogen and oxygen by applying power from PV cells
