Solar panel insurance: What protects your investment

Despite all these advantages, Sonali Solar panels are not without their challenges:

  • Shorter product warranty: Sonali Solar’s product warranty of 12-15 years is shorter than that of some competitors, offering 25-30 years. This could be a concern for some of the customers valuing a longer protection.
  • Lack of detailed efficiency ratings: The company does not provide specific efficiency ratings for all their models, making it difficult to compare different options. Their efficiency ratings are not so bad to hide them, but this lack of transparency is very inconvenient for those looking for detailed technical information.
  • Negative review: Some users have reported issues with customer support, which can be a significant drawback when dealing with technical problems or warranty claims. A few users have mentioned receiving damaged or defective panels, raising concerns about quality control and manufacturing inconsistencies.
  • Poor company info: When you buy expensive equipment, you want to find out as much as you can about the manufacturer. How long the company has been around, where exactly the panels are made, what technology they use. Unfortunately, Sonali Solar does not tell much about themselves.
