Yes, solar panels need maintenance to ensure optimal performance and longevity.
Solar panels only need maintenance two to four times a year. Fall and spring are good times to perform maintenance work because panels can need cleaning following winter where dust and debris can accumulate. The only maintenance cost that is certain is the inverter, which is typically replaced after the system has been operating for roughly 15 years.
Once installed, solar panels are designed to be durable and require little attention. However, solar panels need maintenance regularly with some basic tasks being recommended to ensure optimal performance and longevity.

Regular Cleaning
It’s important to keep the surface of the solar panels clean to maximize sunlight absorption. Dust, dirt, leaves, bird droppings, and other debris can reduce the panel’s efficiency. Cleaning can be done with water, a soft brush, and a mild detergent if necessary. However, it is necessary to be cautious when accessing the panels to avoid accidents or damage. For best results, simply using water and a soft, non-abrasive sponge or cloth to clean away dirt and debris is enough.
Visual Inspections
Periodically, is necessary to inspect the solar panels for any signs of damage, such as cracks, loose connections, or hot spots.
Monitoring Performance
Keeping track of the solar panel system’s performance through monitoring software can help detect any drop in energy production, which may indicate a problem with the panels or the overall system.

Vegetation Management
Solar panels need maintenance, but so does its surroundings. For example, ensure that nearby trees, plants, or structures do not shade the solar panels. Over time, vegetation growth can obstruct sunlight and reduce the efficiency of the panels. Trimming any branches or vegetation that might cast shadows on the panels is a basic maintenance task that can be done regularly.
Inverter Maintenance
The inverter is an essential component of a solar panel system, converting the DC electricity generated by the panels into usable AC electricity. To ensure its proper functioning is necessary to do a periodic inspection.

Professional Maintenance
When the solar panels need maintenance, it is recommended to have a professional solar installer or technician perform the inspection. They can perform more detailed checks and electrical testing, and identify any potential issues that may require repairs.
Now that you know why solar panels need maintenance, find out 5 myths about solar panels.
Solar energy is statistically reliable, effective, easy to install and with a decreasing price curve, becoming one of the cheapest and cleanest energy sources in the world. Universal Kraft’s PV installations are developed responsibly as possible, aiming to be integrated into the social and environmental surroundings.
These installations guarantee a stable use of the location for over 25-35 years, and relatively easy to restore the lands to its original state after this period. It is a form of installation with a limited environmental impact. Also, the materials used can be recovered, recycled and transformed into new solar panels or other products.
