Maintenance of PV plants: The key to long-term efficiency and performance

Operation and Maintenance


Photovoltaic power plants (PV) play a pivotal role in our efforts to reduce emissions and transition towards more sustainable energy generation methods. Nevertheless, these solar installations possess several vulnerabilities that require vigilant monitoring and safeguarding through maintenance practices. In this article, we will delve into the significance of PV plant maintenance and explore the practices that can contribute to extended equipment lifespan and optimal energy production.

Proper Planning: The Cornerstone of a Successful PV Plant

Planning serves as the initial stride toward ensuring long-term efficiency in PV plants. When conceiving a plant, it is imperative to delineate its intended usage and ascertain the data necessary for monitoring operations. For larger installations, collaborating with a specialist maintenance company is a common and prudent choice. Such companies offer both preventive and reactive maintenance services, along with the installation of monitoring systems. Additionally, specifying the data that the PV plant will transmit to remote monitoring systems, encompassing production metrics, control stages, grid quality, and weather station information, holds utmost importance.

Reactive Monitoring: Swift Response to Non-Standard Events

Continuous monitoring of PV plant operations and expedited responses to deviations from the norm are vital facets of maintenance. Skilled technicians armed with essential tools and components stand ready to swiftly restore operations in case of issues. Response times are typically stipulated in contracts and are measured in hours. Technology manufacturers provide cloud-based monitoring systems that facilitate the oversight and control of PV plants.

Preventive Maintenance: Minimizing Downtime

Routine inspections carried out by a service company are indispensable for minimizing unplanned downtimes. These inspections encompass mechanical assessments of the plant's structure, panel cleaning, sensor maintenance, and inverter ventilation. Visual inspections of components, thermal imaging camera assessments of electrical parts, panel illumination checks, and measurements of electrical parameters all play crucial roles. For rooftop installations, inspecting roofing and rainwater drainage is essential, while for ground-mounted installations, maintaining the surrounding vegetation to reduce shading is important.

Storage of Spare Components: Swift Repairs When Needed

To expedite repairs and minimize downtime, it is advisable to maintain a stock of spare components, including inverters, panels, and other critical parts. This measure significantly reduces the time required to procure and deliver the necessary components for restoration.

Optimal care and meticulous planning are the linchpins of successful PV projects. Thorough PV maintenance not only guarantees extended equipment life but also ensures peak performance. These measures enable us to realize our sustainable energy objectives and make meaningful contributions to reducing greenhouse gas emissions.
