Placement

Sunlight Exposure

You need to place your PV panels where they receive the most sunlight throughout the day. Direct sunlight increases the energy your system can generate. Avoid placing panels near tall buildings, trees, or other objects that cast shadows. Even a small amount of shade can reduce the output of your entire PV system.

Tip: Walk around your site at different times of the day. Check for any shadows that might fall on your panels. If you see shade during peak sunlight hours, consider moving the panel or trimming nearby branches.

ESTEL recommends mounting PV panels on the sunniest side of your telecom cabinet. In most locations, this means facing the panels south if you are in the northern hemisphere, or north if you are in the southern hemisphere. This orientation helps you capture the most sunlight year-round.

Panel Angle

The angle of your PV panel affects how much sunlight it absorbs. A flat panel will not collect as much energy as one that tilts toward the sun. You should set the tilt angle based on your local latitude. For example, if your site sits at 30° latitude, tilt your panel at about 30 degrees from horizontal.

• Steps to optimize panel angle:

  1. Find your site’s latitude using a map or GPS.

  2. Adjust the panel’s tilt to match this angle.

  3. Secure the panel firmly to prevent movement from wind or vibration.

Note: ESTEL provides adjustable mounting brackets for telecom cabinets. These brackets let you fine-tune the angle for seasonal changes or unique site conditions.

Proper placement and angling ensure your PV panels deliver reliable power. You maximize efficiency and reduce the risk of power loss. Always follow ESTEL’s guidelines for the best results in your telecom applications.

Cleaning

Dust and Debris

You need to keep your PV panels clean to ensure they work at their best. Dust, dirt, leaves, and bird droppings can block sunlight from reaching the solar cells. When this happens, your panels produce less energy. Even a thin layer of dust can lower efficiency and cause your telecom cabinet to lose power during critical times.

Tip: Inspect your panels after storms or windy days. Leaves and debris often collect on the surface, especially if your site is near trees or busy roads.

If you see any buildup, use a soft brush or a gentle stream of water to remove it. Avoid harsh chemicals or abrasive materials. These can scratch the glass and reduce the panel’s ability to absorb sunlight. For stubborn spots, a mild soap solution works well. Always clean in the early morning or late afternoon to prevent thermal shock from cold water on hot panels.

Maintenance Schedule

A regular cleaning schedule helps you avoid long-term problems and keeps your system running efficiently. Industry experts recommend cleaning solar panels at least twice a year. However, you may need to clean more often if your site is in a dusty area or near heavy traffic.

• Clean your PV panels at least every six months.

• Increase cleaning frequency if you notice visible dirt or if your site experiences frequent dust storms.

• Check for leaves, bird droppings, or pollution buildup after severe weather.

Maintaining a consistent cleaning routine prevents efficiency loss and reduces maintenance costs over time. You protect your investment and ensure your telecom cabinet receives reliable power.

Wiring and Connections

Secure Connections

You need to secure every wire and connection in your PV-powered telecom cabinet. Reliable wiring ensures that energy flows smoothly from your solar panels to your telecom equipment. Loose or poorly connected wires can cause voltage drops, power loss, or even dangerous faults.

Common wiring faults in telecom cabinets include:

• Excessive leakage current, which can trigger inverter shutdowns to protect safety.

• Low insulation impedance from damaged cable insulation, DC leakage, or exposed live parts.

• Reversed polarity connections and open circuits, which may prevent the inverter from starting.

• Loose connections in combiner boxes, leading to voltage or current fluctuations and even fire hazards.

• Improper grounding, which increases the risk of electric shock and equipment damage.

You should always double-check that all terminals are tight and that wires are firmly seated in their connectors. Use cable ties or clips to keep wiring neat and prevent accidental pulls. ESTEL recommends using only high-quality connectors and following their wiring diagrams for each cabinet model.

Tip: Label each wire clearly. This makes future maintenance faster and reduces the risk of mistakes.

Inspection

Regular inspection helps you catch problems before they cause system failures. Look for signs of wear, cracks, or loose mounts on all cables and connectors. Damaged insulation or exposed wires can lead to arc faults, short circuits, or inverter issues.

• Inspect all wiring at least once every three months.

• Check for discoloration, melted insulation, or corrosion on terminals.

• Test grounding connections to ensure they remain secure and effective.

• Verify that breakers and fuses are wired correctly and show no signs of overheating.

PV systems often experience electrical faults such as short circuits, arc faults, and inverter malfunctions. These issues can disrupt power and pose safety risks. Careful inspection and immediate repair keep your telecom cabinet running safely and efficiently.
