Before selecting a system, request a quotation that clearly separates the cost of solar panels, inverter, mounting structure, wiring, protection devices, installation and grid connection.

Which Solar System Is Best for Home?

There are three main types of residential solar systems. The right option depends on your electricity usage, local power supply and backup requirements.

1. On-Grid Solar System

An on-grid solar system connects to the electricity grid. Solar panels generate electricity during the day, and your home uses the available solar power. Depending on local net-metering or net-billing rules, surplus electricity may be exported to the grid.

Best for: Homes with a reliable electricity supply that want to reduce their electricity bills.

On-grid systems generally cost less than battery-based alternatives because they do not require a battery bank. However, standard grid-connected systems usually shut down during a power cut for safety reasons.

2. Off-Grid Solar System

An off-grid solar system works independently of the electricity grid and normally uses batteries to store energy for later use.

Best for: Homes in areas with unreliable grid access or frequent power cuts.

The solar panel installation cost is generally higher when batteries are included. The required battery capacity depends on how much electricity you need during the night and during periods of low sunlight.

3. Hybrid Solar System

A hybrid system combines solar panels, a compatible inverter, battery storage and a grid connection.

Best for: Homeowners who want to reduce grid electricity consumption while also having backup power.

Hybrid systems offer greater flexibility, but their initial cost depends heavily on battery capacity and the features of the inverter.

How Many Solar Panels Does Your Home Need?

The number of solar panels required depends on the system capacity and the wattage of each panel. Modern high-wattage modules can help produce more power from limited rooftop space.

For example, using 600Wp solar panels:

• 1kW system: Approximately 2 panels, providing 1.2kWp of panel capacity.
• 3kW system: Approximately 5 panels, providing 3kWp of panel capacity.
• 5kW system: Approximately 9 panels, providing 5.4kWp of panel capacity.
• 10kW system: Approximately 17 panels, providing 10.2kWp of panel capacity.

These examples show the combined rated capacity of the panels, not the inverter's AC output. Final panel counts and inverter sizing depend on the design.

Higher-wattage panels, including N-Type TOPCon bifacial modules, are worth considering when roof space is limited. Actual output depends on sunlight, temperature, orientation, shading and installation conditions.

Government Subsidy for Solar for Home in India

The PM Surya Ghar: Muft Bijli Yojana supports eligible residential consumers installing rooftop solar systems through approved procedures.

For eligible households in general states, the central subsidy is:

• 1kW system: Up to ₹30,000
• 2kW system: Up to ₹60,000
• 3kW system or larger: Up to ₹78,000

Special-category states and certain regions may have different subsidy amounts. Eligibility, approved equipment, vendor requirements and application procedures must be checked through the official scheme.

The subsidy is subject to scheme rules and approval; it should not be assumed to apply automatically to every solar installation. Additional state-level support, where available, may also affect the final cost.

For current information and applications, visit the official PM Surya Ghar website: https://pmsuryaghar.gov.in/

Example: Solar Panel Installation Cost After Subsidy

Suppose an eligible household installs a 3kW on-grid solar system for ₹1,50,000.

• Estimated installation cost: ₹1,50,000
• Potential central subsidy: ₹78,000
• Illustrative net cost after subsidy: ₹72,000

This is only an example. Your actual cost will depend on the vendor quotation, scheme eligibility and approved subsidy amount. Battery-based systems and installations outside the scheme may have different costs.

What Affects Solar Panel Installation Cost?

Several factors determine how much you will pay for solar for home.

Solar Panel Technology

Solar modules are available in different technologies, including Mono PERC and N-Type TOPCon. TOPCon modules can offer higher efficiency and may help maximise generation from a limited roof area. Compare module efficiency, certifications, degradation specifications and warranty terms before making a decision.

Inverter Capacity and Quality

The inverter converts the DC electricity generated by solar panels into usable AC electricity. Its capacity and compatibility with the panels affect system performance and cost.

Rooftop Condition and Mounting Structure

A roof with sufficient open space and good sunlight is easier to work with. Shading, difficult access, unusual roof shapes and additional structural requirements may increase installation costs.

Battery Storage

Batteries are generally unnecessary for a standard grid-connected system without backup requirements. For off-grid and hybrid installations, battery type and storage capacity can significantly increase the upfront cost.

Installation and Electrical Work

Wiring, earthing, lightning protection where required, AC/DC protection devices, mounting hardware and grid interconnection arrangements are important parts of a complete installation. Make sure these items are included in the quotation.

How to Choose the Right Solar Capacity for Your Home

Start by reviewing your electricity bills for the past 6–12 months. Look at your monthly units consumed rather than choosing a system based only on its advertised price.

A smaller household with moderate electricity consumption may find a 1kW or 2kW system useful, while a home with several air conditioners or high daytime consumption may need a larger installation.

Consider these points before finalising your system:

• Monthly electricity consumption: Use your actual bill history to estimate the required capacity.
• Available rooftop area: Check for shadows from nearby buildings, trees and water tanks.
• Daytime electricity usage: Solar generation is most useful when appliances operate during daylight hours.
• Power backup: Choose a battery-based system if backup during outages is important.
• Future requirements: Account for planned appliances or increased electricity consumption.
• Warranty and after-sales support: Check product warranties, performance guarantees and service availability.

A qualified installer can assess your roof, estimate expected generation and recommend a suitable system size.
