Going solar is no longer just popular; it’s a necessity. The city of Delhi NCR receives over 300 sunny days annually and it is one of the best places in India to establish rooftop solar facilities. Homeowners currently see the benefits of solar power, including reduced electricity bills and support for the environment.
But your solar setup will only work well if the right company installs it. Picking a company with certifications, clear pricing, and experience means your system will last decades rather than fail early.
We’ve put together a list of top TopCon rooftop solar installation companies in Delhi NCR. These companies offer high performance, solid warranties, clear costs, and good customer support after installation.
What does “Best Installation Company” mean?
Top homeowners look at these points when picking a solar installer:
- Clear pricing that shows everything—panels, inverters, structure, wiring, installation, and subsidy details.
- Complete check of your property including roof direction, shadow problems, and weight capacity.
- Quality parts like TopCon panels, good inverters, and weather-resistant wiring.
- Full service package that includes paperwork for net-metering, subsidy applications, installation work, starting the system, and help after it’s running.
- Office and service team located in Delhi NCR, covering areas like Faridabad.
- History of completed projects and real customer reviews.
Companies that miss even one of these points might deliver a system that doesn’t produce enough power or breaks down too soon.
