Bills On Solar Successfully Supplies 7,000 Metres of SUNTREE 6mm² PV Solar Cable for 300kW Solar Installation in Kampala, Uganda

Bills On Solar EA Limited is pleased to announce the successful cross-border supply and dispatch of 7,000 metres of premium SUNTREE 6mm² photovoltaic solar cable to Kampala, Uganda, for the installation of a large-scale 300kW commercial solar power system.

The supply comprised:

• 3,500 metres Red SUNTREE PV Cable

• 3,500 metres Black SUNTREE PV Cable

carefully selected to support safe DC polarity identification, reduced installation errors, and long-distance high-efficiency power transmission across the photovoltaic field.

This successful regional supply demonstrates Bills On Solar’s growing capability in handling utility-scale solar balance-of-system material procurement across East Africa, reinforcing our position as a dependable supplier for:

• EPC contractors

• Commercial solar developers

• Institutional installers

• Government renewable projects

• NGO electrification programs

throughout Kenya, Uganda, Tanzania, Rwanda, South Sudan and beyond.

Project Application: 300kW Solar Power Plant – Kampala Uganda

For a solar plant of this magnitude, cable reliability is not optional.

PV cabling becomes the backbone of:

• module string interconnection,

• combiner box routing,

• inverter DC transmission,

• reduced voltage drop,

• minimized thermal losses,

• long-term outdoor durability.

At 300kW scale, poor-quality cable can lead to:

• excessive DC losses,

• overheating,

• insulation breakdown,

• reduced inverter harvesting efficiency,

• expensive maintenance after commissioning.

This is why the Uganda installation team opted for the globally recognized SUNTREE TÜV Certified 6mm² PV1-F Solar Cable, supplied directly by Bills On Solar.

Why SUNTREE 6mm² PV Cable Was Selected

SUNTREE 6mm² photovoltaic cable is engineered specifically for demanding outdoor solar applications and conforms to international PV wiring standards for utility and commercial systems.

According to manufacturer technical specifications, SUNTREE PV1-F 6mm² cable provides:

Performance Advantages on Large Commercial Solar Projects

1. Ultra-Low Transmission Losses

With conductor resistance of only 3.39Ω/km, the cable ensures minimal DC power dissipation over long string runs, helping the Kampala 300kW plant maintain better inverter input efficiency.

2. Superior UV + Weather Resistance

Uganda experiences strong equatorial UV exposure, heavy rain seasons and humid outdoor conditions.

SUNTREE cable’s:

• UV stabilized outer jacket,

• ozone resistance,

• hydrolysis resistance,

• moisture resistant XLPE insulation

make it highly suited for long-term rooftop and ground-mounted African installations.

3. 25+ Year Solar Lifetime Durability

Solar systems are designed as long-term infrastructure assets.

SUNTREE solar cable is manufactured for over 25 years service life, matching the operational lifetime of commercial PV modules and minimizing replacement risk after commissioning.

4. High Temperature Tolerance

Commercial solar fields regularly experience elevated conductor temperatures due to:

• high irradiation,

• rooftop heat accumulation,

• current concentration.

With operating capability up to 120°C conductor temperature, the cable offers dependable electrical stability under harsh African climate conditions.

5. Easy Installation Flexibility

The fine-stranded tinned copper conductor gives:

• better bending flexibility,

• faster combiner routing,

• simplified conduit pulling,

• lower risk of conductor snapping during installation.

This significantly improves installation speed on utility-scale sites.

Why Color-Coded 3,500m Red + 3,500m Black Matters

For a project of this size, equal lengths of red and black cable were supplied to ensure:

• proper positive/negative polarity distinction,

• cleaner inverter termination,

• easier fault tracing,

• international DC wiring compliance,

• reduced commissioning errors.

Bills On Solar ensured the full dispatch was balanced specifically for high-volume field deployment.

Strengthening Bills On Solar’s East African Regional Supply Footprint

This Uganda supply is another major demonstration that Bills On Solar is no longer serving Kenya alone, but is actively supporting:

• Uganda commercial installations

• Tanzania industrial systems

• Rwanda institutions

• South Sudan NGO electrification

• East African mini-grid developments

with:

• Tier 1 solar panels

• Hybrid inverters

• Lithium batteries

• Mounting structures

• DC/AC protection devices

• Utility grade PV cables

all from one dependable procurement source.

Management Statement

“Supplying 7,000 metres of premium SUNTREE photovoltaic cable to Uganda is a reflection of the trust regional solar developers are placing in Bills On Solar as a dependable East African solar material partner. Large commercial projects require not just products, but products that can survive 25 years in the field — and that is exactly the standard we supply.”
