You are already going to lose power due to the DC/AC conversion. Don't make it worse. Use a good wire size calculator that takes into account volts, amps, distance, etc.
If the DC system voltage is increased, the DC current will drop, and the cables can be thinner. If you want to increase the system voltage, but there are DC loads or DC charge sources that only can deal with 12V, you could consider using DC-DC converters rather than choosing a low voltage for the entire system.
Because PV cables are an essential part of any solar park, their planning is crucial: if cables are too long or the lines are too short they become a wasteful expense. With PVcase, engineers can accurately estimate how many cables they would need to connect all the components in the park.
In general, a DC voltage drop of less than 1% is desirable and the figure must not exceed 2%. A high DC voltage drop also increases voltage dispersion of the PV strings connected to the same .

6 FAQs about [What if the DC line of the photovoltaic panel is too thin ]
What is a good voltage drop limit for solar panels?
Voltage drop limit: Losses in solar PV cabling must be limited, both DC losses in the strings of solar panels and AC losses at the output of inverters. A way to limit these losses is to minimize the voltage drop in cables. In general, a DC voltage drop of less than 1% is desirable and the figure must not exceed 2%.
Can a DC cable be used for a grid-connected PV system?
Cables used for wiring the DC section of a grid-connected PV system also need to withstand potential extremes of environmental, voltage, and current conditions. This includes the heating effects of both current and solar gain, especially if installed near the modules. Here are some crucial considerations.
How to choose a DC cable for a PV system?
Plant owners need to ensure that the size of the DC cable installed is carefully and correctly chosen for the current and voltage of the PV system. The cables used for wiring the DC section of a grid-connected system also need to withstand the extremes of the environmental, voltage and current conditions under which they operate.
What happens if DC voltage drops?
A high DC voltage drop also increases voltage dispersion of the PV strings connected to the same maximum power point tracking (MPPT) system, resulting in higher mismatch losses. Cable loss: To ensure energy yield, it is recommended cable loss of the entire LV cable (from modules to transformer) should not exceed 2%, ideally 1.5%.
How do I reduce voltage loss in PV cables?
A way to limit these losses is to minimize the voltage drop in cables. In general, a DC voltage drop of less than 1% is desirable and must not exceed 2%. A high DC voltage drop also increases voltage dispersion of the PV strings connected to the same Maximum Power Point Tracking (MPPT), resulting in higher mismatch losses.
What happens if a DC voltage is increased?
If the DC system voltage is increased, the DC current will drop, and the cables can be thinner. If you want to increase the system voltage, but there are DC loads or DC charge sources that only can deal with 12V, you could consider using DC-DC converters rather than choosing a low voltage for the entire system.
