Cost to install 3 kW Solar system in 2024

For many Indian households, a 3 kW rooftop solar system is often the perfect fit. However, installing a system of this capacity depends on two key factors: your household’s energy consumption and the amount of shadow-free rooftop space available.

A typical 3 kW system generates around 4,200 units of electricity annually, usually enough to power essential appliances such as 3-4 ceiling fans, 4-5 LED lights, a refrigerator, a television, an AC and kitchen appliances. This capacity is ideal for a 2-3 BHK home, providing an opportunity to reduce grid dependency and lower electricity bills.

Thus, a 3 kW rooftop system is an excellent choice for families seeking to reduce their grid dependency and lower their electricity bills.

Read on to learn more about the cost of a 3 kW solar system, subsidies available, financing options, and tips to choose the right system for your home.

Tips for Choosing the Right 3 kW Solar System for Your Home

1. Opt for a Comprehensive Survey

A quality solar system starts with a detailed survey of your rooftop to check for shadow-free areas, obstructions, and available space. Select a vendor who performs a thorough 365-day shadow analysis to ensure your solar system remains shadow-free year-round. A precise rooftop assessment helps avoid installation issues and maximizes system efficiency. Additionally, evaluating the surroundings of your home is essential, as future developments, like new buildings or growing trees nearby, could create shading problems that impact your system’s performance.

2. Customized Engineering

Every rooftop has unique structural characteristics, so your solar installation should be customized accordingly. Stellar Green’s engineered solutions consider these specific details, creating a tailored layout that optimizes energy generation while ensuring safety and durability.

3. High-Quality Components and RCC Block Mounting

Stellar Green uses RCC block mounting to install solar panels, preventing any permanent structural impact on your roof. We use module mounting structures that are crafted from high-quality materials, including virgin steel and industry-grade components, to deliver reliable performance and withstand challenging weather conditions.

4. Ongoing Maintenance

Regular maintenance is essential to keep your solar system performing at its best and ensuring a long lifespan. Dust, dirt, and debris can accumulate on the panels over time, reducing their efficiency and decreasing energy output. Routine maintenance not only involves cleaning but also includes detailed inspections of each component to detect any potential issues early on.
Stellar Green provides 10 booster maintenance visits across five years, which include professional deep cleaning and comprehensive health assessments.

5. Cyclone-Proof Design

Extreme weather events, such as storms and cyclones, are becoming more frequent, especially in coastal areas like Odisha. To ensure your solar installation stands strong, we use IS 2062-standard mounting structures, engineered to withstand high wind speeds. These cyclone-resistant designs provide durable, weather-resistant protection, making your system a secure, long-lasting investment.

6. Financing Options

Financing a solar system can feel like a big investment, but low-interest solar loans from nationalized banks make it affordable. Through the PM Suryaghar Scheme, most households can access simple, pre-approved, and paperless solar loans via the Jansamarth or PM Suryaghar Portals. Stellar Green streamlines the entire process by assisting with the loan application, managing documentation, and facilitating approval. This hassle-free service allows you to enjoy a smooth transition to solar energy with minimal effort, making your switch both financially viable and convenient.
