On-grid Solar Power Systems or also known as Grid Tied Solar Power Systems is the system which produces the energy on its own but also tied to utility grid from Tenaga Nasional Berhad. It’s means the TNB Grid work as the battery space. There for this system less expensive as it not require the battery to store the energy but the disadvantage is this system is not independent system because it’s reliant upon the TNB Grid.

How does on-grid solar power system works?
The arrangement of solar modules absorbs the sunlight on them and convert them into electricity. The current generated here is Direct Current (DC). The solar inverter then converts the DC to Alternating Current (AC), thus making it power the electrical items. This electricity is then routed to the grid where it is supplied for day to day use. An important feature is a net meter. It is a device that records the energy supplied to the grid and the energy consumed. At the end of each month, the outstanding is recorded and the consumer is provided with a bill.
