Design a one-way circuit to take solar power with no back feed from a power supply in the circuit

Hi, we need an electrical engineer to assist us with a circuit design problem.

We have a solar charge controller and an AC/DC power supply and need the solar to operate a load and if there is excess power send this to Load2 which is being powered by the AC/DC power supply.

So we need a one-way junction circuit and know there must be off-the-shelf devices to do this but need some help please.

See attached drawing.

We want to achieve this using off the shelf components such as reverse protection diodes and NOT to have a microprocessor or software if possible.

Many thanks,
