The task is to compare the power outputs of solar cells, and solar panels. For solar cells, a circuit is devised to work out the power, solar panels a beaker of water is heated.
The Attempt at a Solution
Here is a scan of my two circuits at the moment

For the solar cell, i will use the voltmeter and ammeter to work out the power. However, not sure if a resistor is nnecessary, will it affect the measured output power?
Also, how would I make the experement more accurate? I've already got mirrors to reflect as much light as possible, but would making thew beaker black absorb more light? Aditionally, am I right in thinking that 100g of water = 100ml?
Finally, would I have to multiply the powewr output for the cells by the lenght of time the solar panel is heating?
Thanks very much!
