Utility-scale projects either connect directly to a substation or a transmission line of 69 kV or higher. Unless a solar farm is installed next to transmission lines or substations, the solar contractor needs to install a generation tie to connect the clean energy project to the grid.
Solar farms connect to the grid by converting the direct current (DC) generated by solar panels into alternating current (AC) through inverters. The AC electricity is then transmitted to a substation within the solar farm, where it is further transformed and connected to the broader electrical grid.
The shape of grid lines or fingers, used to reduce conductive losses in photovoltaic cells, is shown to be optimized when the current flux in the line remains constant. This result is derived for cells of arbitrary geometry assuming the fraction of the cell area shaded is small. The shapes of grid lines for three special cases are provided.
Cables play a crucial role in transmitting electrical energy from the solar panels to the inverter, and from there to the grid or battery bank. Inadequate cable sizing can result in significant power losses, voltage drop, and even system failure.
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.
The majority of US residential and commercial PV systems are grid-interactive (or grid-tied), which means that they are designed to be able to export excess power to the utility grid. Export occurs when the power generated by the solar system is greater than the power used by the loads on site.
