The Sun provides endless energy to the earth in the form of sunlight, we call this irradiance. This energy primarily is made up of heat and light. When light strikes the Photovoltaic cell (PV Panel) the energy reacts with the silicon cell causing the electron to break free and create an electrical current.
When we create the energy during the day it is used immediately in the household. While, any excess power, which is not required, is exported back to the grid. Traditionally this meant that regardless of the systems size, when the sun wasn’t shining, you had to buy electricity from the grid.
But, we are now entering a new era of home energy use. With the installation of a Grid-connected Battery System we can utilise excess power created during the day to charge up our battery systems and allowing you to use power when, and how you decide.
