Explain each component
Solar Panels:
Convert sunlight into electrical energy.
Battery:
Stores electricity for later use.
Inverter:
Converts stored DC electricity into AC electricity for compatible appliances.
Charge Controller:
Helps manage charging from solar panels in systems that use a separate controller.
Explain important specifications
Wh — Watt-hours
Shows energy-storage capacity.
W — Watts
Shows how much power the system can provide at a given time.
Peak/Surge W
Important for appliances that require extra power when starting.
Example
A 1,000 Wh battery powering a 100 W device:
1,000 Wh ÷ 100 W = 10 hours
This is a theoretical estimate. Actual runtime will be lower because of inverter losses, battery limits and the device’s changing power consumption.
