For photovoltaic applications, materials used outdoors should be based on UV light, ozone, drastic temperature changes, and chemical attack.
The use of low-grade materials under such environmental stress will cause the cable sheath to become brittle and can even cause the cable insulation to decompose.
All of these conditions will directly increase the loss of the cable system, as well as the risk of a cable short circuit and, in the medium to long term, a higher likelihood of fire or personal injury.
Solar systems are often used in harsh environmental conditions, such as high temperatures and UV radiation.
Typically, the various materials available to us are PVC, rubber, TPE, and high-quality cross-linked materials. However, unfortunately, rubber cables rated at 90°C and PVC cables rated even at 70°C are often used outdoors, which significantly affects the lifetime of the system.
The advantage of solar cables is that they are rated for 120°C (20,000 hours of use). This rating is equivalent to 18 years of use at a continuous temperature of 90°C.
And when the temperature is below 90°C, the service life is even longer.
Typically, solar equipment is required to have a service life of 20 to 30 years or more.
Solar panel wire, in an outdoor environment, last 8 times longer than rubber cables and 32 times longer than PVC cables.
The cables used in the low-voltage DC transmission part of solar photovoltaic power generation systems have different requirements for the connection of different components due to different usage environments and technical requirements.
The overall factors to be considered are the insulation performance of the cable, heat, and flame resistance, aging performance, wire diameter specifications, etc.
Specific requirements are as follows
1. Solar modules and modules between the connection cable, generally use the connection cable attached to the module junction box directly connected, the length is not enough to use a special extension cable.
According to the size of the module power, this type of connection cable has a cross-sectional area of 2.5m ㎡, 4.0m ㎡, 6.0m ㎡ , and other three specifications.
This type of connecting cable has a double-layer insulation sheath, superior resistance to UV, water, ozone, acid, and salt erosion, superior all-weather capability, and wear resistance.
2. The connection cable between the battery and the inverter requires a UL-tested multi-strand flexible cable with as tight a connection as possible. Choosing a short and thick cable can reduce the loss of the system and improve efficiency and reliability.
3. The connection cable between the battery array and the controller or DC junction box also requires the use of UL-tested multi-stranded flexible wire with a cross-sectional area based on the maximum output current of the array.
These are the recommendations of the ZMS cable team personnel. If there is anything else you do not understand, you can always contact the ZMS Cable Team. We will be happy to serve you.
