A grid-connected solar power system is the most
When sunlight hits solar photovoltaic (PV) panels, electricity (or solar energy) is produced.
The electricity runs from solar panels through an inverter. The inverter turns the power from direct current (DC) into alternating current (AC), providing solar electricity to power electronic appliances in the home or office.
As solar power is being produced during the day, and if appliances are in operation, solar power will run through a switchboard, thus powering appliances.
Any appliance that is AC powered can use solar powered electricity; lights, dishwashers, electric hot water cylinders, to name but a few.
If electrical appliances are switched off, or if excess solar power is being produced, the power gets sent to the grid and is measured by the meter box. Electricity retailers
Reduced electricity bill
Protection against power price increases
Allows you to consume 100% renewable energy
No need for costly battery storage
The best way to optimise a return on investment with a grid-connected system is by utilising as much generated solar power as possible.
Using self-generated solar power is worth-while; why waste money on expensive grid power? (typically around 30 cents per kWh). Immediately taking advantage of solar power is the best option for return on investment. Using solar power directly is known as solar power self-consumption, you can find more information on solar power self-consumption.
Separate line items will be viewable on the power bill each month; On the first line is the amount of power used, the price per unit and the total cost of power used (imported power). The second line shows the amount of solar power exported to the grid, the price per unit the energy retailer is paying, and the total credit amount received from exporting power. This credited amount will be subtracted from the total cost of power used.

Standard solar panels have at least a dozen silicon squares within the frame (solar cells). Solar cells convert sunlight (photons) into an electrical current.
Silicon is a semiconductor; it’s able to absorb a percentage of the photons emitted by the sun as they hit the solar cells. As the solar cells are bombarded with photons, the electrons are knocked loose, allowing them to flow freely.
The solar cells have an electric field that
