If no load is connected to solar PV system,

• A. it will dissipate energy in the panel and increase its temperature
• B. it will start reflecting the light
• C. it will stop absorbing light
• D. its voltage will go on increasing till its breakdown

Answer: (A)

At no load the solar cell will be operating in open circuit condition.
If there is internal shunting resistance it will slightly load the solar cell.
This shunt resistance must be high enough such that it will not cause an appreciable loss of the photo voltaic power.
