Solar Power Cell

Jennifer Said:

Can a 0.4-0.5 V solar cell power a light bulb?

We Answered:

NO,you cannot,because the lowest light bulb voltage was 1.2 volts using for a single cell mini flash light. But it requires 300mA to light it up. If your solar cell can supply 300mA at 0.5 volt. It can light up this low voltage light bulb with half brightness. Your small solar cell only able to provide about 150mA.
