This solar panel calculator will, given the Watt rating of a solar panel, the panel dimensions and number of solar panel units to be installed calculate for you the total solar power you can expect and the roof space taken up. It will also tell you the rated voltage and ampage, useful for correctly sizing an inverter or regulator, and for making sure you have the right ampage cable.

Values for the Solar Panel 50 w is normal power
