Neither solar panels, nor hydrogen generators are free. If you need to build extra panels and hydrogen generators, you are making the infrastructure more expensive, consequently raising electricity prices. Or hydrogen prices if you use it as fuel instead of power storage.
You’re not LOSING anything if it’s capturing already excess energy, which would by its nature be lost if not used at the time of generation
