How does solar energy work?
The energy from the sun is captured through solar panels, or photovoltaic (PV) cells mounted on your roof. The electricity generated goes directly into powering your home.
When the sun is shining, solar panels capture sunlight and convert it into solar DC power.
The inverter converts this power into 240V AC electricity that is used by your appliances, and any excess is exported to the grid.
Your house uses electricity from either your solar panels (when they are generating power) or the grid when they are not.
Your solar meter only reads the energy that is produced over the amount that your house uses.
Any electricity that is not used is fed into the electricity grid through your electricity meter. When you are consuming more than you produce you draw electricity from the grid.
What is solar energy?
The energy of the sun, or solar energy, is a free and clean form of renewable energy that can be used to generate electricity using photovoltaic (PV) technology.
Installing a solar energy photovoltaic system will enable you to generate your own electricity and reduce your energy bill. You will also be doing your bit to reduce greenhouse gases.
PV (solar panels) are composed mainly of silicon. Energy, in the form of solar radiation striking those silicon atoms (under certain conditions), can release free electrons, which can move and form an electric current.
PV cells are typically mounted on the side of your roof that has the most exposure to the sun (north or west). These cells convert sunlight directly into DC power. A component called an inverter then converts this DC power into AC power that can be used in your home.
Solar energy systems are available in a range of sizes; a typical system is 1.5kW.
