After doing your solar panel testing you should find that the solar panel output for the pv panel you built on the make solar panels page is about 18 volts and 3 5 amps.

How to test solar panel amps with multimeter.

There are two types of multimeters. You will want to ensure that you place the positive to positive and negative to negative when attaching your multimeter to the connection on the back of your solar panel. A variable resistance box. Whenever you have these two values you can figure out the wattage by multiplying them together.

Analogue and digital multimeter. The latter is preferred as it has more added qualities. You want to choose a voltage range capable of displaying the maximum possible voltage of the panel in open circuit this means that if you have a panel rated for 20 volts you should set the multi meter. How to test a 12 volt solar panel vs other voltages.

A solar cell solar panel to test. As most solar panels are 12 volts the solar panel test methods are basically the same. Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black. A good quality multimeter an auto range preferably or one that can read current and voltage.

This is an easy way to vary the resistance to known settings while it is fixed in the circuit. Measuring the volts and amps of your solar panel using a multimeter. I had a look at dads multimeter and the amps were set out way simpler. I think i stuffed up explaining the amps setting on this one as some of the megas may have been millis.
