After the engineering design of a solar photovoltaic (PV) project is completed, the site preparation process can commence. This process involves several steps, including creating road access to the site, excavation, grading, installation of drainage systems, and perimeter fencing.
Once the site preparation is done, the installation of solar equipment can begin. A typical PV system comprises of PV cells, mounting structure (racking), electrical wiring and connections, mounting hardware, power-conditioning equipment (inverter), and conduit.
The PV cells are mounted on racking structures that face the sun. If tracking systems are installed, these mounts can turn to follow the sun, much like a sunflower, enabling the solar panel to remain in an optimal position to gather sunlight throughout the day.
These racking structures are connected to the balance-of-system components, which are responsible for transmitting electricity generated by the panels to the electric utility grid. The process of installing a solar PV system begins with the installation of these mounting structures.
Once the mounting structures are in place, brackets are used to attach PV panels, and an electrical junction box on each PV panel is then connected to the circuit.
The electricity generated by a solar panel is direct current, but the circuit includes an inverter that converts the direct-current power into alternating-current power that can be fed into the electric utility grid.
Electrical cables are used to collect the electricity generated by each group of panels and transmit this electricity to the point of interconnection with the utility grid.
After installing all panels and balance-of-system equipment, a connection is made to the grid, and the system is energized.
