How Solar Power Systems Work
A solar power system converts sunlight into usable electricity for your home or business:
Solar panels generate electricity during daylight hours
Your property uses solar energy first in real time
Excess power charges a solar battery or is exported to the grid
Stored energy powers your home at night or during outages
When combined with a battery, you maximise self-consumption and reduce reliance on peak-rate grid power.
