How does a solar power system work

Have you ever wondered how solar panels generate electricity from sunlight? When sunlight strikes the photovoltaic (PV) cells of a solar panel, electrons become free and flow around. These free electrons can be trapped and directed in a single route around a circuit. This movement of electrons in the same direction results in the formation of an electric current.

By connecting several photovoltaic cells in a panel and wiring several panels together (referred to as an array), a flow of electrons is formed, resulting in direct current (DC) electricity. The greater the number of panels in an array, the more electricity is generated. We use 240-volt alternating current (AC) power in our homes and workplaces. As a result, a device called an inverter – typically a little larger than a standard shopping basket – is utilized to convert DC current to AC electricity suitable for usage on your premises.

How solar power systems work

Step-1 Silicon photovoltaic (PV) cells comprise your solar panels. When sunlight strikes your solar panels, the solar photovoltaic cells absorb the rays and generate power via the Photovoltaic Effect. Direct Current (DC) electricity is generated by your panels and is not suited for usage in your home by your appliances. Rather than that, the direct current electricity is routed to your central inverter (or micro inverter, depending on your system setup).

Step-2 The inverter may convert direct current (DC) electricity to alternating current (AC) electricity suitable for usage in your house. The alternating current electricity is then routed to your switchboard.

Step-3 A switchboard distributes usable alternating current electricity to the appliances in your home. Your switchboard will always prioritize using solar energy to power your home, drawing additional energy from the grid only when solar production is insufficient.

Step-4 All solar-powered residences are obliged to have a bi-directional meter (utility meter), which will be installed by your electricity retailer. A bi-directional meter is capable of recording not only the energy consumed by the residence but also the quantity of solar energy exported to the grid. This is referred to as net-metering.

Step-5 The excess of solar energy is subsequently fed back into the grid. Solar energy exported to the grid earns you a credit on your electricity bill, referred to as a feed-in tariff (FiT). Your electricity bills will then reflect the electricity you purchase from the grid, as well as credits for electricity generated by the solar energy system but not used.

Solar energy eliminates the need to manually turn on or off the system in the morning or at night – the system will do it flawlessly and automatically. Additionally, you do not need to switch between solar and grid electricity because your solar system can identify the optimal time to switch based on the quantity of energy consumed in your home.

Final Words

Photovoltaics create an electric current, which is then converted into an alternating current (AC) by an inverter. AC is the type of electrical current used when you plug appliances into normal wall sockets – it’s the same as normal household plug sockets.
