Its voltage and temperature ratings, conductor size, installation route, and compatibility with the rest of the system all matter. The right choice depends on the project and the electrical code adopted where it is built—not simply on whether a cable looks suitable.
What is PV wire?
Photovoltaic (PV) wire is a single-conductor wire designed for use in photovoltaic systems. UL 4703, the principal U.S. standard identified for PV wire, covers sunlight-resistant wire for interconnection wiring in grounded and ungrounded PV systems. Its scope includes dry temperature ratings of 90°C, 105°C, 125°C, or 150°C; a wet rating of 90°C; and voltage ratings of 600, 1,000, or 2,000 V. These are available ratings, not a claim that every PV wire product carries all of them. Check the marking and the manufacturer’s data sheet for the ratings of the specific product.
PV wire connects modules and other PV equipment as part of a complete electrical system. A cable’s color, physical fit, or appearance does not establish that it is listed for the intended use. Look for its product markings, manufacturer specifications, listing or certification information, and installation instructions. UL explains that component wiring generally is not evaluated for field installation unless it is part of a complete listed product or system in its Wire and Cable Application Guide.
What does UL 4703 mean?
UL 4703 identifies the scope and ratings for photovoltaic wire; it is not a substitute for checking whether a particular cable is suitable for a particular system. UL’s listing records the standard as active and gives August 11, 2020 as its last revision. Read the product’s actual ratings against the project’s maximum system voltage, wet and dry conditions, temperatures, and installation method. The standard’s listing is available from UL Standards & Engagement.

A cable may have a rating that is inadequate for one condition even if it is suitable for another. In particular, do not assume that a dry temperature rating applies to wet locations, or that a familiar voltage rating is sufficient for the system. Use the exact product documentation and the equipment maker’s instructions.
What wire do I need for solar panels?
Start with the designed system and the wire’s complete route, not with a generic “solar cable” label. Selection involves the electrical load, distance, system voltage, voltage-drop considerations, ambient and conductor temperature, conductor material and type, and installation conditions. Grouping and the applicable code calculations can also affect the final conductor selection. Because those inputs vary by project, there is no universal wire size that can be recommended from the fact that a system uses solar panels.

Check each candidate against these selection points:
- Intended use: Is the exact product listed or identified for the intended application and route?
- Voltage: Is its voltage rating suitable for the system’s maximum voltage?
- Temperature and exposure: Do its wet and dry temperature ratings suit the environment and installation?
- Conductor size and ampacity: Do they meet the design and code calculations after relevant conditions are applied?
- Wiring method: Is the cable appropriate for the route, protection, and exposure specified by the design and applicable code?
- Connections: Are the wire, connectors, terminals, and equipment compatible according to their manufacturers?
- Traceability: Can you verify the manufacturer’s specifications and listing information for the exact product?
The U.S. Department of Energy’s older 2007 guide describes basic sizing factors such as ampacity, run length, voltage, temperature, and conductor type; it is useful for understanding those factors, not for relying on its historic code examples as current requirements. See DOE’s solar thermal and photovoltaic systems guide. A qualified designer or electrician should make the project-specific calculations under current requirements.

Can I use regular wire for solar panels?
Do not substitute ordinary building wire based on appearance or a general claim that it is weather-resistant. The exact cable must be identified or listed for the intended use and meet the system’s electrical ratings and installation conditions. PV wire is one recognized option, but it is not the only wiring method that may be allowed in every installation. NEMA’s Engineering Bulletin No. 103, revised August 22, 2024, discusses PV wire and other Chapter 3 wiring methods that may be acceptable under NEC Article 690 depending on the installation. The adopted code and the specific product determine what is acceptable on a given project.
How do code and installation method affect the choice?
Wiring method, protection, and product ratings must suit the route and the applicable code. NEMA’s 2024 bulletin explains U.S. NEC context but is technical guidance, not a replacement for the code text in force locally. It also notes that conduit sizing for PV wire must use the conductor diameter supplied by the manufacturer because the NEC dimensions discussed in the bulletin do not provide a standardized PV-wire dimension. Use the actual product data rather than a guessed or generic diameter.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How should solar cable be routed and secured?
Route and secure wiring so it is protected, does not create a safety hazard, and does not impair system operation. Cable management is part of installation quality, not merely appearance: poorly managed cables can create hazards or performance problems. DOE’s photovoltaic installation and commissioning guidance advises against plastic wire ties. See DOE’s installation and commissioning guidance.

Exact support hardware, spacing, and routing details depend on the adopted code, equipment and cable instructions, and site conditions. Avoid applying a spacing rule from an old code edition or a different installation without confirming it fits the project.
How do I connect solar panel wires?
Use connectors and terminals suited to the equipment, wire, and installation, following the manufacturers’ instructions. UL identifies UL 6703 as the standard for PV connectors and describes solar materials and component certification in its Solar Materials and Components Certification information. A physical connection alone does not establish that two connector products are compatible or listed for the application. Verify connector suitability, wire compatibility, and equipment instructions before making a connection; do not assume products from different manufacturers can safely mate just because they fit together.
Who should confirm the final selection?
PV wiring is part of a system whose ratings, routing, connectors, and installation method must work together. Use manufacturer documentation and the locally adopted code to verify the design. When the electrical inputs, code calculations, or product compatibility are uncertain, have a qualified solar professional or electrician resolve them before installation.
