What are Solar PV systems? 

• Solar PV systems, also known as solar panels, are made up of photovoltaic cells that convert sunlight into electricity. 

• These cells are typically made of semiconductor materials like silicon. 

• When sunlight hits these cells, it excites electrons, creating an electric current. 

How do they work? 

• Solar panels capture sunlight and convert it into direct current (DC) electricity. 

• This DC electricity is then passed through an inverter, which converts it into alternating current (AC) electricity, the type used in homes and businesses. 

• The AC electricity can then be used to power appliances, or it can be stored in batteries for later use. 

What are the benefits? 

• Solar PV systems offer a clean and renewable source of energy. 

• They can help reduce electricity bills and reliance on fossil fuels. 

• Excess electricity can be exported back to the grid, potentially earning income for homeowners. 

What are the different types of solar PV systems? 

• Grid-tied systems: These systems are connected to the electricity grid and can draw power from it when needed, or export excess power back to the grid. 

• Off-grid systems: These systems are completely independent of the grid and typically use batteries to store electricity. 

Where can solar PV systems be used? 

• Solar PV systems can be installed on rooftops, in solar farms, or in other locations where there is access to sunlight. 

• They can be used to power homes, businesses, and even remote locations without access to the grid.
