This article answers the question: how does solar power feed back into the grid? In a grid-connected system, solar energy first supplies your home, and any extra energy is then fed back to the grid. Likewise, if your solar system does not generate enough energy, the grid provides the shortfall. Keep reading to learn how it works. For the bigger picture, see our guide to how solar panels work.
Solar panel array
A solar panel array is the collection of solar cells we often see on roofs. These panels convert sunlight into direct current. The inverter then transforms that energy and pushes it along the line going to your home. In most cases, people keep the grid connected to the solar system.
Grid-feed system
With a grid-feed system, you need an inverter that allows electricity from your home to be exported to the grid. The solar energy system will prioritise your own power needs first. Exactly how much you can send back may be capped, which we cover in solar export limiting explained.
Grid-tie reverse effect
Solar energy systems must be able to draw from the grid in reverse. This means you have a consistent power supply even when your solar system is not producing energy, giving you a reliable backup to power your house.
How does solar power feed back into the grid?
For this to work, the solar energy system needs to be intelligent, so it can automatically send the surplus energy from your panels to the grid. This is what helps reduce your annual electricity bills, and it is closely linked to how feed-in tariffs work.
What equipment or systems do I need?
To connect to the grid, your solar energy system needs electricity metering and safety equipment. This may include high-standard inverters or controllers.
Conclusion
In a nutshell, arranging and connecting the whole system can be involved, and the solar panel array is arguably more important than the inverter itself. Solar Air Energy will set up an intelligent solar energy system for you. Get a free quote and we will take care of the rest.
