Solar energy is a long-term investment that provides clean and cost-effective electricity. Proper maintenance is essential to ensure your solar system operates efficiently for decades. With regular care, solar panels can last over 25 years while maintaining optimal performance. Let’s discover practical ways and tips for maintaining your solar system, common issues that may arise, and the role of EPC companies like Mahindra Solarize in providing maintenance services.
Regular Cleaning of Solar Panels
Cleaning solar panels in India is essential to maintain their efficiency, especially in areas with high dust, pollution, or industrial activity. The frequency of cleaning varies based on local conditions. In urban areas like Mumbai, where pollution levels are high, it’s advisable to clean panels every 3–4 months to prevent dust accumulation that can reduce energy output by up to 25% . In coastal regions, salt residue may necessitate cleaning every 3–4 months . For rural or less polluted areas, cleaning twice a year might suffice
Homeowners can clean their panels using soft brushes and water during cooler parts of the day, such as early morning or late evening, to avoid thermal shock and water spots . However, for hard-to-reach installations or when panels are heavily soiled, it’s safer to hire professionals. They use specialized tools and eco-friendly solutions to ensure thorough cleaning without damaging the panels.
Checking for Shading and Obstructions
Shading from trees, buildings, or other structures can reduce the efficiency of solar modules. Over time, trees grow and cast shadows on the panels, leading to reduced power output. Regularly trim any nearby trees and check for any new obstructions that might block sunlight. Even partial shading on one panel can affect the performance of the entire solar system.
Monitoring Inverter Performance
The solar inverter is the heart of a solar power system, converting DC power from the panels into AC electricity for home use. A malfunctioning inverter can reduce the overall efficiency of the system. EPC companies like Mahindra Solarize offer excellent post installation support, ensuring your PV inverter operates smoothly and efficiently.
- Check the inverter display regularly for error messages or warning lights.
- Ensure proper ventilation around the inverter to prevent overheating.
- If you notice a sudden drop in energy production, the inverter could be the issue. Contact your service provider for inspection.
Common Solar System Issues and How to Address Them
Although solar systems require minimal maintenance, specific issues can affect their efficiency over time. Identifying and addressing these problems early can help maintain consistent energy output and extend the system’s lifespan. Below are some of the most common solar system issues and practical solutions.

Reduced Power Output
A sudden drop in solar energy production can indicate a problem. One of the most common reasons for this is the accumulation of dust, dirt, or bird droppings on the solar panels. When sunlight is blocked, even partially, the system produces less electricity. Other potential causes include shading from growing trees or nearby structures and inverter malfunctions.
How to Fix It:
- Clean the solar panels regularly to remove dust and debris.
- Trim overgrown branches or remove any new obstructions that may cast shadows on the panels.
- Monitor the solar inverter for any error messages or unusual performance drops. If needed, contact a professional for an inspection.
-
Worn-Out Wiring and Loose Connections
Over time, weather conditions, rodents, or poor installation can cause the wiring to become loose or damaged. Faulty electrical connections can lead to power losses or, in extreme cases, system failure. Rodents may chew through cables, exposing the wires and increasing the risk of short circuits.
How to Fix It:
- Schedule annual inspections with a professional to check for loose connections or worn-out wiring.
- Ensure that all electrical components are securely fastened and properly insulated.
-
Sustaining Long-Term Performance
Solar panels are designed for durability, delivering reliable energy for 25+ years. Over time, factors like weather, temperature variations, and UV exposure may slightly reduce efficiency.
How to fix it:
- Perform regular system checks to ensure optimal panel performance.
- Update components, such as inverters or mounts, when needed to maintain output.
- Collaborate with a trusted provider, like Mahindra Solarize, for routine care and system enhancements.

Role of EPC Companies in Solar Maintenance
EPC (Engineering, Procurement, and Construction) companies play a key role in the maintenance of solar systems. Companies like Mahindra Solarize provide comprehensive post-installation services, including:
- Regular maintenance checks help ensure that the solar system operates at peak efficiency by identifying potential issues early.
- If an inverter or panel malfunctions, a thorough fault diagnosis can pinpoint the issue and restore optimal performance.
- Defective components can be replaced through warranty claims, ensuring long-term reliability without additional costs.
Maintaining your solar system is simple and ensures long-term efficiency. Regular cleaning, inverter checks, and professional inspections help keep the system at peak performance. With support from EPC companies like Mahindra Solarize, homeowners can enjoy hassle-free maintenance and maximise their investment in solar energy. By following these care tips and utilising government incentives, you can ensure a reliable and sustainable power supply for years to come.
