Common Questions About Residential and Industrial Solar Rooftop Systems Installation

With over 10 years of experience, 50+ MW of solar power installed, and more than 4,500 happy clients across Gujarat, Navi Energy has become a trusted name for residential and industrial solar rooftop solutions. Below are the most common questions people ask us before installing a solar system, and our expert answers.

General Questions

A solar rooftop system uses solar panels installed on your roof to convert sunlight into electricity. This power can be used directly in your home or factory, helping reduce dependence on grid electricity and lowering your power bills. Grid-connected systems also allow you to export excess power through net metering.

Yes! Gujarat has high solar radiation throughout the year. With subsidies, net metering, and reduced electricity bills, most users recover their investment in 4–5 years and enjoy free power for 30+ years.

  • Residential systems are usually 1–10 kW and designed for homes.
  • Industrial systems can go from 25 kW to several MW, depending on load requirements.
    The components are similar, but industrial systems are larger, need higher-capacity inverters, and may follow a more complex approval process.

Choosing a reliable vendor ensures quality and peace of mind. Look for:

  • MNRE-approved/registered vendors on the National Portal
  • Experienced companies like Navi Energy with 4500+ satisfied customers in Gujarat
  • Good after-sales service and support

To modify the proposed kW capacity:

  • Log in to your account on the portal
