Solar panels – to generate electricity using sunlight. The current produced is DC.
Solar Inverter – converts direct current from solar panels to alternate current. AC is usable by your home appliances.
Battery – It stores the energy from solar panels for later usage, during the night or cloudy sky.
Solar Charge Controller – It saves the battery from overcharging and damage by limiting the voltage and current it receives.
Working of an off-grid solar power system:
1. When solar radiation hits the solar panels, free electrons get released that create an electric current.
2. The DC energy from solar panels is converted to AC with the help of an inverter.
3. This AC power gets supplied to the load.
4. The excess power generated by solar panels is to charge the battery for the power supply during the nighttime or on cloudy days.
- Benefits of Off-grid solar power system:
- No requirement for connection to grid power.
- Independent power generation for captive power consumption.
- Freedom from electricity bills.
- Safeguard against grid-connected power outage.
