Solar photovoltaic (PV) panels, usually fitted to the roof, convert sunlight into direct current (DC) electricity. The number of panels installed will depend on the nominal size of your system. Collectively groups of these panels are referred to as a solar array.

The DC electricity generated is converted into alternating current (AC) via the inverter (generally accessible at ground level, often located inside the garage). The converted electricity (AC) is now suitable for consumption by your home’s appliances. Most inverters include a digital display so you can monitor the system’s information such as the amount of solar electricity produced, etc. Please refer to the separate inverter manual for further information.

If you already have a smart meter installed, this may need to be reprogrammed to be able to measure both your electricity imported and electricity exported. If you have an old electro-mechanical meter (the one with the spinning disk), this will need to be replaced with a bidirectional meter able to record the electricity you both import and export.

Your electricity retailer will continue to read your meter at regular intervals (i.e. quarterly) and bill you for the electricity you consume from the grid. Any solar-generated electricity exported to the grid will be applied as a credit on your account at the rate you negotiate with your electricity retailer. This is known as a Feed-in Tariff.
