Global solar PV generation marked a historical milestone by surpassing wind for the first time ever in 2022. Solar PV additions are projected to continue to increase in 2024, according to the International Energy Agency. However, amid soaring growth projections, there have been a few critical challenges that the solar PV industry has been facing. Let’s take a look at those challenges.
In this blog, we will look at the key challenges faced by the solar industry and uncover five game-changing ways that drones transform the solar energy industry by helping overcome those challenges.
Critical Challenges Faced by the Solar PV Industry
Drones have become a game-changer in the renewable energy sector, offering a range of innovative applications that optimize solar PV installations’ performance and maintenance. However, in the absence of drones, the industry would face key challenges that may hinder the industry’s scalability, competitiveness, and ability to meet the ever-increasing demand for clean and sustainable energy solutions. Let’s take a closer look.
Critical Challenges Faced by the Solar PV Industry
- Limited Data Collection
- Inefficient Anomaly Detection
- Increased Costs
- Labor-Intensive Manual Inspections and Safety Risks
- Limited Scalability and Reduced Competitiveness
Limited Data Collection
Accurate and comprehensive data is essential for understanding the performance of solar PV installations, identifying potential issues, and making informed decisions for optimization. Without efficient data collection methods, the solar PV industry may struggle to gather real-time information on solar energy generation, irradiance levels, and system health.
Manual data collection can be time-consuming and labor-intensive, leading to delayed insights and hindering proactive maintenance. Inadequate data may also impact the ability to assess the long-term performance of solar PV systems and make necessary adjustments for increased efficiency and profitability.
Inefficient Anomaly Detection
The solar photovoltaics industry faces significant challenges stemming from the inefficiency in fault detection. Timely detection of faults or issues in solar PV systems becomes challenging without the aid of drones, leading to potential decreases in energy production and higher maintenance costs.
The lack of drone technology limits the industry’s ability to integrate further advanced technologies, such as artificial intelligence (AI), machine learning (ML), and advanced data analytics, which otherwise provide valuable insights into solar plants’ performance and efficiency. As a result, solar PV companies may struggle to optimize system performance, diagnose potential problems promptly, and make data-driven decisions to enhance overall operational efficiency and power generation capacity.
Increased Costs
While solar energy offers long-term cost savings through reduced operational expenses and lower dependence on traditional energy sources, the initial investment required for solar PV installations can be substantial. Without cost-effective solutions for inspections and data collection, the solar PV industry may face higher expenses related to labor, equipment, and maintenance. Manual site surveys, inspections, and maintenance can lead to prolonged project timelines and increased manpower requirements, translating to higher overall costs. Moreover, without efficient data-driven insights powered by advanced technology, identifying areas for optimization and ensuring maximum energy production may become costlier and more complex.
Labor-Intensive Manual Inspections and Safety Risks

Traditional methods of inspecting solar PV installations often involve human personnel climbing rooftops or navigating through solar farms to identify issues and perform maintenance. These manual inspections can be labor-intensive, time-consuming, and expose workers to potential safety hazards, especially when dealing with installations at height or in remote locations. The risk of accidents, falls, and other on-site incidents can lead to injuries and even fatalities, compromising worker safety and well-being. Additionally, manual inspections may not always provide comprehensive and accurate data, leading to delayed fault detection and potential performance issues.
Limited Scalability and Reduced Competitiveness
The solar PV industry faces a dual challenge due to the limited scalability caused by inefficient data collection and monitoring methods, coupled with reduced competitiveness in the absence of drone technology. Without drones’ advanced capabilities for data collection and monitoring, companies may struggle to manage and monitor numerous solar sites effectively, hindering scalability to meet the growing demand for renewable energy solutions.
Additionally, drone technology empowers solar PV companies with increased efficiency, cost savings, and data-driven decision-making, providing a competitive advantage that companies without drones may find challenging to match. This reduced competitiveness could impede industry growth and market share, limiting the ability to offer innovative and cost-effective solutions in a fiercely competitive renewable energy landscape.
How Are Drones Used in Solar Plants?
Drone analytics serves as a tool that identifies defects at the solar panel level. It can be utilized as a standalone solution for reviewing solar module defects. Thermal imaging and its analytics involve third-party drone vendors to capture thermal and visual raw images. In a multi-step process, these images are used to create high-resolution, detailed images (orthomosaics).
What is the Role Played by Artificial Intelligence in Drone Analytics?
The AI/ML-based image processing examines the captured images to find and categorize defects at the individual panel level. Once the system detects the defects, it overlays the images with the plant architecture to determine their respective table and string numbers. By using the image’s geo-coordinates, the system maps the defects to specific tables, making it easier to locate them in the field.
