How electrical battery storage enhances solar PV
- Solar photovoltaic (PV) panels convert the sun’s light energy (photons) into direct current (DC) electricity.
- The current flows into an inverter which is used to convert the DC electricity into usable 240v alternating current (AC) electricity.
- The AC electricity is fed through a generation meter into your distribution board to supply power to your home or business.
- When solar generated electricity exceeds your immediate electricity demand a control system will divert the power to charge a battery.
- When your immediate electricity demand exceeds that which is being generated through your solar system, power will be drawn from the battery. This reduces your need to buy-in electricity from your energy supplier meaning you can use your own (solar generated) supply at any time of the day.
- Any surplus electricity (i.e. when the battery is fully charged) is fed back into the National Grid for use by others.
