What is Solar Energy?
Solar energy is radiant energy from the sun. It is the primary source of energy for all life forms.
The sun shines, allowing plants to grow for food sources or bio fuel. The sun’s heat causes temperature differences, producing winds that can power wind turbines. The sun also causes water to evaporate, making hydropower possible.
The term solar energy is often used to refer to the various ways we can use the sun’s energy to produce light, heat and electricity.
It is an infinitely renewable resource and unique for its ability to generate energy in a quiet, clean, and consistent manner.
How does PV work?
Solar radiation from the Sun is captured by solar panels, which produce electricity in the form of direct current (the same current as a battery). The energy generated by solar panels can be used in conjunction with batteries and/or an inverter to power electric devices in a home or business.
How does a solar PV cell generate electricity?
At the heart of a solar PV system are photovoltaic cells; devices which are capable of converting light into an electric current. These photovoltaic cells do the ‘clever bit’ of transforming the sun’s energy into electricity.
How does the electricity spread through the home?
The electricity produced by solar panels is known as DC (direct current) electricity. The electricity in your house is known as AC (alternating current). To convert the electricity into AC an Inverter is installed, which converts the energy and makes it available for your household appliances.
