My Solar Panel Has Voltage But No Amps

Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black.

My solar panel has voltage but no amps.

Zero output is a common problem and in nine out of ten cases it is due to a faulty inverter or charge controller. All of the panel s amps are available but only 12 of the panel s 18 volts. If this doesn t work try doing this again but only this time first reconnect the panel then the battery. Some exceptions may apply based on panel type.

For example if the solar panel is rated at 175 watts and the maximum power voltage vmp is given as 23 6 volts. Discussion in general electronics discussion started by jim n mar 7 2013. Volts but no amps from a small solar panel reply to thread. It sounds like you have wired the new panels backwards to the rest of the array.

Try disconnecting both the panel from the regulator and the regulator from the battery then reconnect them battery to regulator first then panel to regulator. Measure the solar panel controller output voltage try to get maximum voltage by angling the panels. If it is proceed. The missing power is not lost to inefficiency of the controller it is never produced.

Solar panel produces volts but no amps. Since power watts is volts x amps only 12 18 66 7 of the potential power is harvested. Open circuit voltage can vary depending on your solar panel but the readings we are usually looking for are in the range of 15 to 23v. Zero power output no power low voltage issue.

Connect the ve solar controller output lead to the ve battery terminal. This 12v 5w solar panel was intendeds to charge a lead acid battery that in. Hopefully it is less than the solar panel controller output voltage. Mar 7 2013 1.

Solar panels wired backwards to vs to parallel connections act like a dead short solar panels are just a bunch of giant diodes connect them in the wrong polarity the panels will simply be a large set of diodes connected backwards and take current from the rest of the array. It s also possible that one solar panel in your pv array failed. Measure the battery voltage. Calculate the current in amps by dividing power in watts by the voltage in volts.
