I can get 20 4volts on open circuit but no amps at all on the short circuit current.
Solar panel has voltage but no amps.
Turn the panel away from the sun and the voltage will go down but still no amperage.
It sounds like you have wired the new panels backwards to the rest of the array.
If the fuse circuit breaker at your battery is ok check the continuity from the junction box to the line side mc 4 connector.
Hello i have solar system complete with one battery but it has not served for a year and when i measured the charging of the panel and to from the charge controller it is giving me different voltage only decreasing after from the charger and to the loads from the battery there is very high very fast discharge of voltage what can i do about it.
Only open circuit voltage.

All of the panels wattage will go to volts.
If your solar panel controller also has a regulated voltage output voltage is never more than 12 13v dc then the current supplied to the battery may depend on the voltage that the battery has e g if the solar output is 12 3v and the battery is 12v then the battery is only being charged by 0 3v and the charging current will be small.
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.
If it is good then check the continuity from the load side mc 4 connector to the input to the controller.
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.
Dec 23 2019 how many amps are in a 200 watt solar panel.
Solar panel volts no amps.
I have an 80watt 12v solarpanel that is just 12months old and has decided to throw the towel in.
Solar panel produces volts but no amps.
Solar panels have voltage but no current output.
Point the solar panel directly into the sun and read the amps you will get none.
