Solar Power : How does solar power work?
Solar energy systems convert sunlight into electricity using technology such as photovoltaic (PV) panels, also known as solar panels.
When you install a solar energy system, your home uses electricity produced by the panels. Electricity you generate but don’t use can be fed back into the main electricity grid and your retailer will pay you for this energy.
To feed electricity into the main electricity grid, you need a new meter that can measure two way flows of electricity (into and out of the grid)—your solar installer will be able to confirm whether your existing meter is suitable or whether you need a new meter installed.
