The current from the parallel connected string (often called a "block") will then have a lower current than the remaining blocks in the module. This is electrically identical to the case of one shaded solar cell in series with several good cells, and the power from the entire block of solar cells is lost. The figure below shows this effect.
Strings of solar panels operate at high voltages, up to 600V or higher. Operating at these elevated voltages over many years can, in some cases, allow a current leak to develop through the cells to the aluminium frames of the solar panels and into the earth, resulting in a significant performance loss.
No, It’s not advised to have your panel wired in parallel when they have the same voltage. They should be wired in series if they have the same voltage. What happens if mismatched solar panels are connected together?
The article addresses a common issue where a solar panel shows voltage but no current (amps), leading to a malfunction in the system. It discusses the diagnostic process, including checking standard ratings and setting up the panels for optimal sunlight.
If the connecting cables of your solar panel are partially connected, or not even connected at all, there will be a breach in your circuit and so, no current will be able to flow through your circuit.
Your Solar Panel Circuit has a lot of equipment. One of the main pieces of equipment is Solar Charge Controller. Now if it is broken your entire circuit will be busted. In the worst-case scenario, the current will stop flowing. Thus there will be zero amps despite voltage. Usually, low-quality charge controllers have this problem.
Deye Parallel 8kW not working the same
When I looked up spec I saw this sheet. The 2 x 22A may depend on model variants or firmware change that allows higher PV current when PV voltage is lower but still staying within 8kW limit. This sheet with 18A + 9A would be 8KW at 300 vdc PV inputs. 22A + …
PV Parallel setting
It looks like both inputs have to match each other, which is likely why it says in the booklet not to mismatch panels. I have 2 different arrays; one going to DC1 and the other to DC2. If I enable "PV Parallel," it beeps and shuts down both inputs because one is at 70 volts and the other at 100 volts.

Panels wired in Parallel but Amps not adding up
I rewired the panels in Parallel to see the difference. In Parallel, Volts are as expected, about 18. However, Amps are not adding up, but remain as if the panels are wired in Series. I measured the Amps directly from the panels before any current etc. reached the Charge Controller, and the Amps remain as if from a single panel, not additive of ...

Should You Wire Your Solar Panels In Series Or Parallel?
Your solar panel output voltage needs to exceed the charging voltage of your batteries before they can begin charging. Because Volts add with series wiring, the output of your PV array will hit that charging voltage much earlier in the day compared to a parallel system, and will continue charging for longer. Where to Find the Voltage of Your Solar Panels. You have 12 …
Connection of solar panels: series or parallel?
The voltage of all the panels is added together and the amperes remain constant. Parallel panels. How does paralleling work? Well. The positive poles are connected on one side and the negative poles on the other. In other words, the solar panels are not connected to each other to a central cable, but we are talking about a parallel circuit.

Amps not adding-up with parallel connection
You drawing do not show the solar panels in series (to increase the volts), which is probably why you are getting such poor performance. Adding the panels in series adds the volts together (+ve of one to -ve of next), added them in parallel (+ve to +ve, -ve to -ve increase the amps>> this is all in DC at this point.
Mismatch Effects in Arrays
In a larger PV array, individual PV modules are connected in both series and parallel. A series-connected set of solar cells or modules is called a "string". The combination of series and parallel connections may lead to several problems in PV arrays. One potential problem arises from an open-circuit in one of the series strings.
