What does "interconnection" mean in the context of solar systems?

In the context of solar systems, "interconnection" refers to the process of connecting a solar power system to the utility grid. This step is crucial because it allows the energy generated by the solar panels to be fed into the grid, enabling the system owner to utilize the electricity produced, and potentially sell excess energy back to the grid, depending on local regulations and net metering policies. Interconnection ensures that the solar installation complies with safety and technical standards, allowing for seamless and safe operation alongside the existing electricity infrastructure.

Connecting a solar power system to batteries, while related to energy storage, does not encompass the broader perspective of interconnecting with the utility grid. Similarly, directly connecting a solar power system to appliances does not accurately reflect the comprehensive process defined as interconnection, as it leaves out the essential link to the grid. Installing solar panels on a roof is a critical step in the installation process but is not what defines interconnection within the realm of solar energy. The precise definition of interconnection emphasizes its role in integrating renewable energy systems within the existing power distribution framework.
