    First, solar panels are DC and the vast majority of transmission lines are AC. Even if you were on an HVDC line, the voltages would be a massive mismatch.

    What I've always wanted to look at is electrified rail. Those voltages are commensurate with PV technology. You could, in theory, cover all of the electric rail corridors with PV and plug those directly into the system.

      which is pretty small. Therefore they can pass electricity into the electrical grid when they are producing more energy than receiving from outside. Since power companies in South Carolina are supplementing their grids with solar panels they place on customers' houses, I thought this could be an effective way to make up the losses. I know that does not involve high tension wires, but it certainly is not limited by the fact the solar is DC power.

      We have a house in Baja California that is run on Solar Power, and the whole house is AC, we have it connected to an inverter.  DC requires very thick and expensive wiring, it needs to be converted to AC to effectively power the house.

        about attaching solar panels directly to transmission lines. That is not feasible.

        Putting them in the distribution system is terrific and it actually saves the electric utility more money than it costs them even with straight up net metering!
