The table below outlines the 3 kW solar panel price in Delhi, with installation—both with and without the subsidy.

Tips for Selecting the Right 3 kW Solar System

1. Choose a Vendor That Conducts a Proper Roof Survey

Some local providers skip essential steps like surveying your roof, which can lead to overlapping panels or inefficient structures. Pick a company that uses technology to perform a year-round shadow analysis, identifying obstructions that could affect performance. 

They should also assess your available roof space and energy consumption to design an optimised system, minimising risks such as hotspots, lower power output, or even potential fire hazards.

2. Opt for Engineered Solar Solutions

Make sure your solar provider customises the system based on your roof’s specific structure. This ensures the installation is safe and efficient, and offers a better return on your investment.

3. Select a Vendor That Guarantees Savings

According to a study by CEEW and PV Diagnostics, more than half of solar installations underperform in their first year, with output dropping 30% further in the second year. Protect your investment by choosing a vendor who guarantees savings and promises to compensate you if the system underperforms, so you get the most value from your solar installation.

4. Prioritise Vendors with Certified, Secure Structures

As extreme weather events become more common in India, it’s essential to choose a solar system capable of withstanding harsh conditions. Opt for vendors offering certified, cyclone-resistant structures that can handle high wind speeds, ensuring your solar panels remain secure for years.

5. Look for Comprehensive Maintenance and Support

Regular maintenance is crucial for optimal solar system performance. Don’t overlook after-sales service when selecting a vendor. A reliable provider will offer comprehensive maintenance packages to keep your solar panels operating at peak efficiency for the long term.

6. Go for Verified Financing Options

Installing solar panels requires a significant upfront investment. Choose a vendor that provides financing options verified by reputable institutions, making it easier to manage the initial costs of going solar without breaking the bank.
