Using the same three 6 volt, 3.0 amp panels as above, the total output of the panels, when connected together in parallel, the voltage output would remain the same at 6 volts, but the amperage would increase to 9.0 amps (3 + 3 + 3), or 54 watts.
A monthly salary is the amount of pay you receive every month for doing your job. This also implies that you will be paid monthly, though it may not be the case. You can calculate a monthly salary even if you are paid biweekly or semi-monthly.
Your salary is an expressed amount of pay that you receive weekly or less frequently, such as $600 weekly or $1,500 biweekly. Wages are based upon your hourly rate, such as $9 per hour; in this case, your pay is based on the number of hours you work during the pay period.
