A solar cell is a DC device with a positive and negative terminal. You are seeing a negative voltage because you connected the positive lead of your meter to the solar cell's negative terminal, and the negative lead of your meter to the solar cell's positive terminal.
The positives of using solar panels include lower electric bills if any. Negatives include the potential impact on electric companies and the expensive cost, making them not accessible to everyone. Lastly, solar panels contribute to safer industrial factories.
Put the red positive meter lead on one side and the black negative lead on the other. This measures across the terminals or wires of the solar panel. You must set the volt meter to read DC Volts. If there’s a negative number displayed on the voltmeter then that means that the leads are pointing in the wrong direction.
Even when inside a building, a simple voltage reading will reveal the polarity of a solar panel. Put the red positive meter lead on one side and the black negative lead on the other. This measures across the terminals or wires of the solar panel. You must set the volt meter to read DC Volts.
Some solar panels are energy negative, meaning they take in more electrical power than they generate. This is good because it allows you to store excess energy from your system for later use or sale back onto the grid – this makes switching over to renewable sources of electricity easier!
This is what protects your appliances from damage due to excess voltage in the solar circuit, but it also allows for any of that excess voltage to dissipate out of the inverter and be used by other parts of the utility grid. So this negative pole can actually help you get paid more money when selling back your energy to the grid.
