Residential solar power generation and access to the grid

How do solar power systems contribute to the grid?

By contributing to the grid, solar power systems participate in a process known as grid feedback, where renewable energy sources like solar help offset non-renewable energy use. Properly sized solar power systems are designed to minimize the amount of excess electricity fed back into the grid, ensuring efficient energy distribution.

Why should a solar PV system be connected to the grid?

For financial benefit. Connecting your solar PV system to the grid allows you to take advantage of the FIT, which gives you a fixed amount of money for each kWh of electricity you generate. On top of these payments for energy generation, you also receive a sum of money for feeding any surplus energy into the grid.

Can solar panels be connected to the National Grid?

Connecting solar panels to the National Grid means you can potentially earn money back through a feed-in tariff. Click here to find out more.

How can solar energy be integrated?

By 2030, as much as 80% of electricity could flow through power electronic devices. One type of power electronic device that is particularly important for solar energy integration is the inverter. Inverters convert DC electricity, which is what a solar panel generates, to AC electricity, which the electrical grid uses.

Why do solar panels need a grid-tie inverter?

When excess electricity from solar panels flows back into the grid, it undergoes an important conversion process through inverters to ensure compatibility with the grid’s AC system. This synchronization, facilitated by grid-tie inverters, guarantees a smooth integration of solar power without disruptions.

Can rooftop solar power a two-way grid?

However, systems like rooftop solar now require the grid to handle two-way electricity flow, as these systems can inject the excess power that they generate back into the grid. Increased solar and DER on the electrical grid means integrating more power electronic devices, which convert energy from one form to another.
