How Does a Solar Farm Connect to the Grid?
If the nearest transmission line to your property has a voltage of, say, 115 kV (115,000 volts), the output voltage from the solar farm needs to "step up" to 115 kV to feed power into it. Likewise, the power that line carries to a neighborhood 50 miles away eventually needs to "step down" in voltage so that homes can use it.
