In recent years, the application of solar power (PV) power generation has become more and more extensive and has developed rapidly. In the construction process of the photovoltaic power station, in addition to the leading equipment, such as photovoltaic modules, inverters, and step-up transformers, the photovoltaic cable materials connected to the photovoltaic power station have a significant impact on the overall photovoltaic power station. Profitability, operational safety, and high efficiency also play a crucial role, and you must be very careful when choosing PV cables. Otherwise, you may buy wires that don't meet your specific needs. The ideal photovoltaic wire must meet the requirements of the UL 4703 standard for photovoltaic wire. Here's an overview of all the features you need to be aware of
1. Conductor size: 18 AWG to 2000kcmil, TUV popular size solar cable 4mm to 6mm.
2. Conductor material must be copper and tinned copper
3. Insulation material must be XLPE or XLPO
4. Acceptable voltage is 600V, 1KV or 2KV
5. The cable must be resistant to sunlight
6. Acceptable temperature ratings are 900°C wet, 1050°C dry, and 1500°C dry
8. Its structure should be single conductor, non-armored
What is a suitable PV wire size?
Some of us like to take shortcuts in life. If you are one of these people, you shouldn't try to cut corners when choosing the ideal PV wire. Instead, it will be best if you take the time to carefully consider all options and choose the correct wire size for your specific application.
The appropriate wire size will vary based on your specific needs. There is no particular size that fits all applications. If you choose an undersized PV wire, there will be a significant voltage drop across the wire, resulting in substantial power losses. The cables could heat up to a fire point in the worst case. You don't want this to happen, do you? So, how do you choose the right photovoltaic wire size?
Each PV wire size can handle a specific amount of current. For example, a 10 AWG PV wire can allow up to 30 amps delivered from a single solar panel. If you choose based on the amount of current you intend to pass through the wire, it will be the best choice. The amount of current in a solar system varies by brand and module of solar panel. Therefore, it is always recommended to consult your local PV solar cable specialist before choosing a PV cable.
What are the types and advantages of commonly used photovoltaic wires?
With the definite increase in the number of homes and commercial spaces using solar energy, there has been a lot of interest in solar cables. Photovoltaic wires must meet several requirements to be eligible for use in solar systems. Any photovoltaic cable must withstand environmental, mechanical, chemical, and electrical damage.
Today, tinned copper photovoltaic cables are commonly used in residential and commercial solar applications. Why is copper the ideal conductor material? Well, copper is very conductive. Therefore, it can carry more current than other conductors of the same size.
Are you looking for efficient photovoltaic solar cables? It is best to choose one with stranded tinned copper conductors. Why is it essential to choose stranded wire? Stranded wire is slightly more conductive than solid wire because of its larger surface. Therefore, stranded wires are always recommended in large solar types as they can carry more current. Furthermore, the flexibility of the Litz wire is an added advantage, as solar installations generally require maximum flexibility.
What is the proper PV wire amperage?
The proper PV line amperage depends entirely on your solar system's total amperage. For example, if your system draws ten amps, you will need an 11 or 12 amp wire. Why choose a PV line that can handle more current than the system can produce? It is recommended to use a slightly taller wire than the system-generated wire. This helps ensure it can take the current.
You have to remember that different wires can carry different amounts of current. For example, a 6mm solar PV cable can handle up to 70 amps, while a 4mm solar PV cable is rated for 55 amps. If you're not sure what type of wire is right for your needs, it's best to consult your local PV wire specialist.
