On-Grid and Off-Grid Solar Systems:
There are two main types of solar power systems: on-grid and off-grid. Both systems work by converting sunlight into electricity using solar panels, but they differ in how they store and distribute that energy.
On-Grid Solar Systems
On-grid solar systems, also known as grid-tied systems, are solar power systems that are connected to the public electricity grid. When the solar panels generate electricity, it is fed into the grid and used to power homes and businesses in the area. If the solar system generates more electricity than is needed, the excess energy is sent back to the grid and the user receives a credit on their electricity bill.
On-grid solar systems consist of several components, including solar panels, an inverter, and a metering system. The solar panels capture energy from the sun and convert it into direct current (DC) electricity. The inverter then converts the DC electricity into alternating current (AC) electricity, which can be used to power homes and businesses. The metering system tracks the amount of energy generated by the solar system and the amount of energy consumed by the user, and determines the net energy use.
One of the key advantages of on-grid solar systems is that they provide a reliable source of electricity, even on cloudy days or during periods of high energy demand. They also allow users to take advantage of net metering programs, which can help to offset the cost of the system by providing credits on electricity bills.
