Applications Of Solar Cells

Gerald Said:

What is "dummy cells" in solar cells applications means?

We Answered:

I believe they are test cells, used for test purposes, in models, and not for actual say, solar panels.

Beverly Said:

watt - kilo watt usage?

We Answered:

Watts are a unit of power. Power is energy per unit time. By definition, a watt is a joule per second. So the answer to your question is that a 60 watt light bulb requires 60 watts to power. It requires 60 joules per second. A 10 watt solar panel produces 10 watts, or 10 joules per second.

You will frequently hear the electricty company talk about kilowatt-hours. This is a convenient unit of energy (Power times Time). So if a 60 watt light bulb is on for an hour, then it has used 60 watt-hours (or 0.06 kW-hrs) of energy.
