One 1.5 mm² class 5 core, 30 strands of 0.25 mm, PVC insulated and rated 1000 V DC. 19.5 A, 13.3 Ω/km, 29 mV/A/m across the go-and-return pair. This is the workhorse small size on a home solar job: panel-to-charge-controller runs on a one or two panel array, the wiring inside a DC board, and 12 V and 24 V circuits that carry real current over a short distance. About 1.33 kg of copper in 100 m. Drawn on the Pilone line in Lahore.

Check the coil before you pay for it
Every coil leaves our factory with a QR code printed on the packaging. Scan it and the factory record for that batch opens: brand, cable size, batch number, year of manufacture and conductor. Compare the batch number on screen with the one printed on your coil — if the two do not match, it did not come from us.
Specifications
Resistance per IEC 60228. Current capacity uses BS 7671 method C (clipped direct), 30°C ambient, as the nearest published reference for a single current-carrying DC conductor — actual solar-circuit ampacity depends on run length, grouping, and your inverter or charge-controller rating. Verify sizing with a licensed electrician or your solar installer.

Where this cable belongs
Small-array panel runs
Panel-to-charge-controller wiring on a one or two panel system, where string current stays in single figures and the roof-to-board distance is short.
DC board and enclosure wiring
Links between breakers, fuses, isolators and terminals inside a DC combiner or board, where runs are measured in centimetres.
12 V and 24 V load circuits
Lighting, fans and DC sockets fed from a battery bank — sized on volt drop, not on the 19.5 A.
Volt drop is current × route metres × 29 mV/A/m ÷ 1000, and the 29 already counts the positive and the negative leg, so use the one-way route length. Solar work is designed to 3% on the DC side. A 6 A string on a 100 V array has a 3.0 V budget: 3.0 × 1000 ÷ (6 × 29) = 17 m of route — a real roof-to-board distance, which is why this size works on small arrays. Take the same 6 A down to a 24 V battery circuit and 3% is 0.72 V, worth 4.1 m. Take it to a 20 m controller-to-battery run and the drop is 6 × 20 × 29 ÷ 1000 = 3.5 V, which on 24 V is 14.5% — nowhere near acceptable. Battery and inverter runs are why installers jump to 6mm DC cable and larger, even where the amps look small.
Single-core DC cable, not AC building wire. The 19.5 A comes from BS 7671 method C at 30°C as the nearest published reference for one current-carrying conductor; on a Lahore roof in June the ambient is well above 30°C and the figure derates. Size the string current with your panel's rating plate, not a rule of thumb, and have your solar installer or a licensed electrician confirm it — the cable size calculator is a starting point.

Frequently asked
What is the price of 1 core 1.5mm DC cable in Pakistan?
There is no fixed rupee figure — the conductor is copper and the rate tracks the daily copper price, so a listing from last month is stale. Pilone sells factory-direct from Lahore with no dealer margin. Send the length in metres and your city on WhatsApp at +92 319 4262451 for today's per-metre rate. Before comparing any other quote, ask whether it is per metre or per coil.
What is 1 core 1.5mm DC cable used for?
Panel-to-charge-controller runs on a small array, wiring inside a DC board or combiner, and 12 V and 24 V load circuits. 19.5 A is the heat limit, but on a low-voltage battery circuit the 3% volt-drop budget usually decides the size well before the amps do.
Should I use XLPE solar cable instead?
For cable sitting in the sun on a roof, yes. XLPE is rated to a higher conductor temperature than PVC, which is 70°C here, and takes continuous exposure better. This PVC build suits protected runs: boards, enclosures, trunking and indoor DC. Tell us where the cable will sit and we will say which construction to send.
Is 1.5mm DC wire enough for my solar panels?
For one or two panels over a short run, usually yes. Take your string current from the panel rating plate and work the drop: 6 A over a 17 m route on a 100 V array is 3.0 V, exactly the 3% budget. Longer roof runs, higher string currents, or any battery or inverter run push you to 4mm² or 6mm DC cable.
Can I use house wire like 3/.029 or 7/.029 for solar panels?
Not for the DC side. The problem is not the copper — 3/.029 computes to 1.28 mm² and is sold as 1.5 mm², close to this cable — it is the rating. House wire is a 300/500 or 450/750 V AC building cable, not a 1000 V DC cable, and PVC house wire on an open roof hardens and cracks. Use cable rated for the DC voltage and the exposure.
