Net metering is great, much better than being paid for the surplus.

With net metering the grid is basically an free, infinite, 100% effective battery.

    Only while there's a surplus. Our net metering arrangement effectively forfeits any surplus at the end of the year. It obviously can vary by region and how much you'd get from surplus vs specifics of the net metering policy, but I think getting paid for surplus is simpler and easier to plan around.

    I disagree, but in not in your situation so I can be wrong.

    Unless you are producing way, way more electricity than you can use I think net metering is a great arrangement for the customer. (Not so much for the utility company)

    The electricity is usually bought by the utility company at a much lower cost than what the customer is paying. Because the generation cost is only a percentage of the cost, there is taxes, maintenance of the grid ...

    For example in France we pay 0.1952€/kWh, but the utility is buying the solar electricity produced by household at 0.04€/kWh.

    Meanwhile with net metering your electricity is virtually bought at the same price as what you are buying your electricity for.
