Depends on local market and policy environment, as well as technology maturity and cost.
The profitability of photovoltaic power generation to produce hydrogen depends mainly on the local energy market and policy environment, as well as the maturity and cost of the technology photovoltaic energy production and hydrogen production. If the local government has relevant supporting policies, such as subsidies or tax incentives, or the energy market has demand for high-value hydrogen, then photovoltaic power generation to produce hydrogen hydrogen will be more profitable. With the continuous progress and cost reduction of solar panel technology and water electrolysis, the cost of hydrogen production from photovoltaic power generation will gradually decrease, thereby improving its cost-effectiveness.
