Decentralised Solar Power at Homes

• Solar PV gives DC Power

• But load is AC
• Needs a DC-AC convertor

• Now if we add a battery

• Battery stores only DC
• Require a AC-DC convertor for charging
• Require a DC-AC convertor during discharging

• For low power, each convertor* can have 10 to 15% loss

• Solar with battery may have 25 to 45% loss
