It starts with the solar panels.
Solar panels (also called photovoltaic or PV panels) capture energy from the sun and turn it into DC power. This is essentially done by harnessing speeding photons to create an electrical current within a solar panel. To get the best out of a solar system and generate more electricity, panels are usually mounted on your roof that has the most sun exposure, typically north or north west. Modern solar panels are not only efficient and produce high ‘yields’ (amount of energy they produce), but are built to last, where the standard conforms to a 25 year performance warranty.
Which leads to the inverter.
That feeds the meter and the grid.
Most people will be connected to the grid. This means that even though you have installed a solar system on your home or business, you will still have the security of knowing you can call on your electricity grid. This may happen on a cloudy day or at night time!. As a rule, your home or business will first use the electricity generated by your solar panels and any excess electricity that the system generates, will be fed back into the grid.
