For an eligible residential customer, a 3kW solar system can receive a subsidy of up to ₹78,000 under the PM Surya Ghar: Muft Bijli Yojana, subject to the applicable scheme rules and eligibility.
For example:
3kW solar system cost: ₹2,00,000
Less: PM Surya Ghar subsidy: ₹78,000
Effective cost after subsidy: ₹1,22,000
This subsidy can significantly reduce the initial investment in a residential solar system. Customers should confirm their eligibility and the applicable subsidy amount at the time of installation, as government scheme rules and procedures may change.
The final system price can vary depending on the solar panel and inverter brand, system specifications, roof type, mounting structure, cable length, installation requirements and other site-specific work. When comparing quotations, check that all essential components and installation services are included.

What Is Included in a 3kW Solar Installation?
A complete 3kW solar installation is more than just solar panels. A properly designed system includes the panels, inverter, mounting structure, electrical protection, wiring, earthing and installation work. MNRE’s rooftop-solar documentation also identifies modules, inverter, mounting structures, energy meter, DC/AC distribution boxes, earthing, lightning/surge protection and cables as key system components. Solar Rooftop
Solar Panels
Solar panels convert sunlight into electricity. The type and wattage of panels determine how many panels are required for a 3kW system.
When selecting panels, consider:
- Panel technology: Modern monocrystalline panels are commonly used for residential rooftop systems because they provide good power output from limited roof space.
- Warranty: Check both the product warranty and performance warranty offered by the manufacturer.
- Efficiency: Higher-efficiency panels can produce more power from the same roof area.
For systems installed under government schemes or net-metering arrangements, the applicable MNRE requirements should also be checked. MNRE maintains an updated Approved List of Models and Manufacturers (ALMM) for eligible government-assisted and net-metering projects. Ministry of New and Renewable Energy
Solar Inverter
The solar inverter converts the DC electricity generated by the panels into AC electricity that can be used by household appliances.
The main options are:
- On-grid inverter: Suitable when the main objective is reducing electricity bills. It works with the electricity grid and does not normally provide backup during a grid outage.
- Hybrid inverter: Combines solar, grid and battery operation, making it suitable when both bill savings and backup power are required.
- Off-grid inverter: Designed for systems that operate independently of the electricity grid and normally require batteries.
The right inverter depends on the customer’s electricity consumption, backup requirements and type of solar system.
Mounting Structure
The mounting structure securely holds the solar panels at the required angle and helps them withstand outdoor conditions.
Common options include:
- Galvanized steel structure: Strong and commonly used for rooftop installations.
- Aluminium structure: Lightweight and corrosion-resistant, depending on the design and application.
- RCC roof: The structure is generally anchored to the concrete roof using a suitable mounting arrangement.
- Metal sheet roof: Requires a mounting solution designed specifically for the roof profile and structural condition.
The installer should assess the roof before finalising the structure rather than using the same design for every property.
Electrical Protection
Safety components are an important part of a solar installation and should not be removed simply to reduce the quotation.
A typical system may include:
- DCDB: Provides protection and isolation on the DC side between the solar panels and inverter.
- ACDB: Provides protection and isolation on the AC side of the inverter.
- SPD: Helps protect the system against electrical surges.
- MCB: Provides circuit protection against excessive current and short circuits.
- Earthing: Provides a safe path for fault currents and helps protect people and equipment.
- Lightning protection: May be required depending on the building, location and overall electrical protection design.
Proper earthing and protection should be designed according to the applicable electrical standards and site conditions. MNRE technical documents specifically include earthing, lightning and surge protection as part of solar PV system requirements. Solar Rooftop
Installation & Commissioning
Installation is the process of putting all these components together and making the system ready for operation.
A professional installer normally:
- Inspects the roof and confirms the installation location.
- Plans the panel layout and mounting structure.
- Installs and secures the mounting structure.
- Installs and connects the solar panels.
- Installs the solar inverter.
- Connects DC and AC cables with appropriate protection.
- Completes earthing and required safety connections.
- Checks the electrical connections and system parameters.
- Tests the system before commissioning.
- Completes applicable documentation and net-metering procedures for eligible on-grid installations.
A good installation is important because the quality of mounting, wiring, protection and commissioning can affect the safety, reliability and long-term performance of the solar system.
