What’s The Difference Between 10 Square Meters And 16 Square Meters of Photovoltaic Cables

In the whole solar power station system, in addition to photovoltaic modules, photovoltaic cables are an indispensable part, and the selection of photovoltaic cables is also very important for current calculation. For different components, the following factors should be considered when selecting PV cables:

• The PV cable must be able to safely carry the working current and short-circuit current of the module.

• The size of the PV cables should be large enough to ensure that the losses generated by the PV cables are within an acceptable range and to maintain the most economical balance between the capital cost and the operating cost (loss) of the enterprise. Power generation calculation formula.
  

• Power generation formula: line loss (cable voltage %) = photovoltaic cable length x maximum current x resistivity at a given temperature / (cable cross-sectional area x line voltage)

Photovoltaic cables should be sized to prevent voltage drops from exceeding legal limits that could affect the performance of the equipment.

In order to reduce line losses, larger components need to increase the cross-sectional area of the photovoltaic cable. Select different PV cable specifications at 10 square and 16 square for the same level of line loss control, and further compare the total PV cable price per watt of different components in different system designs.

Of the two different types of solar systems, the total PV cable cost per watt will be higher for larger size modules. Especially for wiring, the cost of photovoltaic cables occupies a considerable proportion, which will directly lead to a substantial increase in the total cost of the system.
