As a renewable energy company in India,AMPIN Energy Transition is dedicated to advancing sustainable energy solutions. One of the most effective methods for harnessing solar energy is through solar for rooftop & ground mounted installations. However, like any other installation, these solar panels can experience low performance over time. It is essential for homeowners and businesses to understand the causes of this low performance, its impacts, and strategies to minimise it.

Causes of Solar Panel Low performance

1. Environmental Factors:

  • Pollution: Accumulation of dust, dirt, and other pollutants on the surface of solar panels can lead to hotspot issues and can lead to module burn out once it happens there is no other option rather that changing the entire module so proper cleaning of module (with water or robotic cleaning) should be done.

2. Manufacturing Quality:

  • The durability of solar panels is significantly influenced by the quality of materials and craftsmanship during the manufacturing process. Always check whether the material of the panel is suitable of our climatic situation before purchasing dynamic mechanical load and static mechanical load tests are done for the modules to ensure the durability of the modules.

3. Improper Installation:

  • Loose Connections: Increased resistance leads to power loss, reducing energy output.
  • Open Circuit: A poor connection could interrupt the circuit, causing the module or the entire string to stop generating power.
  • Module Damage: Prolonged exposure to electrical stress due to poor connections may degrade the module over time result in the low performance.

4. Electrical Stress:

  • Issues like overvoltage or poor electrical connections can lead to overheating and damage to internal components over time.

Effects of Low performance in solar panels

1. Reduced Efficiency:

  • As solar panels degrade, their capacity to convert sunlight into electricity declines. This drop in efficiency can result in lower energy output and higher electricity costs.

2. Increased Maintenance Costs:

  • Panels that have degraded may need more frequent replacements, leading to greater long-term expenses for homeowners and businesses.

3. Shortened Lifespan:

  • While most solar panels are designed to last 25 years or longer, significant degradation can reduce their effective lifespan.

Ways to Minimise Solar Panel Low performance

1. Regular Maintenance:

  • Arrange routine inspections and cleaning of solar panels to eliminate dirt and debris that could block sunlight.
  • Proper grass cutting and O&M needs to be done for Business owner.
  • Ensure there are no loose connections and leakage current

2. Quality Installation:

  • Select reputable solar firms in India that offer high-quality installation services. Proper installation helps reduce risks associated with environmental factors and electrical stress.

3. Select High-Quality Panels:

  • Invest in high-efficiency solar panels from reliable manufacturers known for their durability. Look for panels that come with a robust warranty as an indicator of quality.

4. Monitor Performance:

  • Use monitoring systems that track the performance of your solar energy system. Early detection of inefficiencies allows for prompt maintenance or repairs.

5. Protective Measures:

  • Consider installing protective barriers or coatings that shield panels from environmental stressors such as or excessive UV exposure.
