Panel specs include a WORKING VOLTAGE value. Residential panels that require an MPPT controller are rated way higher than 17 volts working voltage. Open Circuit Voltage is another clue closely related to Working Voltage.
A high voltage panel used with a low voltage system is like using a 3,000 PSI water faucet connection that delivers a maximum of a gallon a minute to a garden hose.
So you mean a 17.0 VOLT WV, not a 17 watt panel. The watts, being so low, had me confused. 17 watts, with a working voltage of 17.0V is 1 amp charging rate... not enough to charge much of anything, including lap tops or smart phones.
