What are the parts of the solar system

23 Mar 2018
Depending on the system’s connection to the electricity grid, different components are integrated in a solar power system. Generally, all the systems include PV modules, wiring, and the associating construction materials.

1. In an off-grid solar power system, additional components include battery banks, a charge controller, an optional backup generator, and an optional inverter. While in the off-grid hybrid system, other renewable energy generators such as the wind turbine are added in addition to the components in the off-grid solar power system.

2. In a grid-tie system, additional components include a solar production meter, a switching unit, an export/import meter, an inverter, optional battery banks and the associating charge controller

Solar cells are assembled together to form solar panel. Through PV effect, the solar cells capture sunlight and turn it into direct current (DC) electricity. For off-grid system, the DC can be immediately used for DC loads if there is no inverter or the DC can then be directed to an inverter, which converts DC into alternating current (AC) that is suitable for conventional electric appliances. For the off-grid system, excess energy generated from the PV panels is usually stored in batteries, controlled by the charge controller, for use at night when there is no sunlight. An optional backup power such as diesel generator can be installed if electricity from the batteries run out. For grid-tied system, DC is converted into AC to be used on-site or stored for backup if the system includes battery banks. When there is more demand, power can be drawn from the grid. Excess supply of electricity from the PV panels can also be fed back into the grid. This process of drawing and feeding electricity to the grid is monitored by the solar production meter and the export/import meter.

Solar modules can be arranged into arrays that are large enough to function as power stations converting sunlight into electrical energy for industrial, commercial, and residential use. Solar modules in smaller configuration can be installed on buildings for residential or commercial use. Solar panels can also be used in remote areas where there is a short supply of electricity or where electricity cannot be delivered such as in space.
