Common Installation Challenges

Shading Issues

You need to watch for shading when installing PV panels on telecom cabinets. Even a small shadow from a nearby tree, antenna, or building can cause a big drop in energy output. Partial shading reduces the current from your PV panels because the solar cells connect in series. When some cells get less sunlight, the whole panel produces less power. You may see multiple peaks in the power-voltage curve, which makes it harder to get the most energy. If shading increases, your system’s output can drop to almost zero. Always check for potential sources of shade during your site assessment. Place your panels where they get full sunlight throughout the day.

Tip: Trim nearby trees and avoid placing equipment that casts shadows near your PV panels.

Water and Corrosion

Outdoor telecom cabinets face harsh weather. Rain, humidity, and temperature swings all bring moisture that can damage your equipment. Condensation inside the cabinet often happens when temperatures change quickly, especially in cold climates. Water can get in through ponding, small crevices, or poorly installed gaskets. Once inside, moisture causes corrosion, especially if different metals touch or if the cabinet sits in a salty or humid environment.

Use cabinets with weatherproof construction and proper sealing.
Install weatherproof cooling systems to control humidity and temperature.
Eliminate crevices and make sure gaskets fit tightly.
Apply protective coatings to metal surfaces.

Note: Regularly inspect your cabinet for leaks or signs of rust. Early action prevents costly repairs.

Cable Management

Good cable management keeps your system safe and efficient. Cabinets with built-in cable trays and tie points help you organize cables and prevent tangling. Organized cables improve airflow, which helps your equipment stay cool. You also reduce the risk of accidental disconnections and make maintenance easier.

Use Velcro ties instead of plastic zip ties to avoid damaging cables.
Keep cable bundles loose and avoid stacking them too tightly.
Maintain proper bend radius and cable length to prevent signal loss.
Plan for future cable needs to avoid congestion.

Proper cable management supports reliable performance and makes troubleshooting much faster. You save time and reduce the risk of costly downtime.

PV Panel Maintenance

Cleaning Panels

You need to keep your PV Panel clean to maintain high energy output. Dirt, dust, and bird droppings can block sunlight and reduce efficiency. Clean your panels every three to six months or after major storms. In dusty areas, you may need to clean them more often.

Use soft, natural-material brushes or sponges, such as bamboo bristles, with water or a mild detergent.
Avoid harsh chemicals and abrasive materials that can scratch the surface.
Try waterless vibration tools or nanoparticle coatings if you want to reduce water use and prevent abrasion.
For large installations, robotic cleaners can remove debris efficiently without causing damage.

Tip: Always avoid leaving standing water on the panels to prevent corrosion.
