On Grid Solar Rooftop System: The Key Components
An on-grid solar rooftop system has several key parts. These include solar panels, inverters, net meters, and the grid interconnection. They all work together to make and share solar energy.
The solar panels are at the heart of the system. They turn sunlight into electrical energy. These panels, on your rooftop, catch the sun’s power and change it into direct current (DC) electricity.
The inverters are next in line. They change the DC electricity from the solar panels into alternating current (AC) electricity. This is the power used in your home and the local utility grid.
The net meter is key for tracking energy flow. It measures how much electricity your solar panels make and how much you use from the grid. This helps you manage your energy use and might even earn you credits for extra energy sent to the grid.
Lastly, the grid interconnection connects your system to the local power grid. It lets you use grid power when your solar panels don’t make enough. It also lets you send extra energy back to the grid.
These parts work together to make your rooftop a renewable energy source. They use the sun’s power in a sustainable way.
“The key to unlocking the full potential of an on-grid solar rooftop system lies in understanding its essential components and how they work together.”
