Choosing the best solar company depends on quality, experience, and service. Thermosun is one of the best solar companies in Delhi, with 5+ years of experience and 1000+ satisfied customers. Known as a top-notch solar service provider, Thermosun offers reliable installation, quality products, and complete support including subsidy assistance.

TOPCon and bifacial panels are different technologies. TOPCon offers higher efficiency and better long-term performance, making it ideal for rooftop installations. Bifacial panels generate power from both sides, giving higher output in open spaces. Many modern solar panels combine both, giving you the best of both technologies.

The best solar inverter for home depends on reliability, efficiency, and after-sales support. In India, popular options include Luminous, Microtek, V-Guard, Delta, and Tata Power Solar. For most households, a hybrid inverter is recommended because it works with solar panels and batteries, providing backup during power cuts and better energy management.

To choose a good solar company, check these key factors:

• Experience of 5+ years

• 1000+ successful installations or satisfied customers

• Use of high-quality solar panels and inverters

• Proper support for subsidy and net metering

• Strong after-sales service
