Solar panels absorb the sun's energy throughout the day and convert it into direct current (DC) electricity. The DC electricity is passed through inverters to convert it to the AC electricity businesses use. At that point, you either use the electricity at your business or send it back to the electric grid. The amount of power your solar energy system generates is dependent on the sunlight they capture each day. As a result, your solar panels will produce less energy when the weather is cloudy, and no solar energy at night.
