Why Solar Energy for House in India?
India has excessive sunlight and over 300 days of the sun annually, thus solar power can be used to supply solar power for households. Household solar panels are cheaper than ever now with the increased technological advances and government assistance.
Major Reasons why Indian Homes are going to Solar:
- Rising electricity unit prices ( 6-10 per unit).
- Power Bills On-long term savings.
- MNRE Government subsidies.
- Minimized maintenance demands.
- Solar panel lifespan of 25 and above.
To the majority of homeowners, it is no longer a luxury to have solar panels on your house but a smart financial choice.
Home Solar Power systems types in India.
Prior to comprehending the expenses, one needs to be aware of the kind of systems that can be installed to provide home solar.
Given below are the types of solar power systems:
Grid-Tied Solar System, Off-Grid Solar System, Hybrid Solar System
- Grid-Tied Solar System
A grid-tied solar is one that is integrated directly to the utility electricity grid. It produces power by the use of solar panels and delivers energy to your house or building. The surplus power generated is sold to the grid.
How It Works?
- The solar panels produce DC power using sun-rays.
- DC is converted to AC using grid tied inverter.
- Your home first uses electricity.
- Overpower is directed to electricity grid.
- In the case of insufficiency of solar power, electricity is attracted to the grid.
Key Components:
- Solar panels
- Grid-tied inverter
- Net meter (bi-directional meter).
- Grid connection
Advantages:
- Reduced start-up fee (no batteries needed)
- Large power efficiency and reduced loss.
- has net metering advantages.
- Low maintenance
- Faster return on investment
Limitations:
- Does not operate during power outages (safety reason)
- Completely reliant on grid power.
Best Suitable For:
- Urban homes and apartments
- Commercial buildings
- Regions that have stable power.
- Off-Grid Solar System
A solar system that is not tied to the utility grid is the off-grid solar system. It charges itself in batteries and provides power even when it is not connected to the grid.
How It Works?
- Electricity is produced using solar panels.
- Power to batteries is regulated through charge controller.
- Batteries store energy
- Inverter transforms the stored DC to the AC.
- Whenever power is needed to be supplied to loads, it is provided.
Key Components:
- Solar panels
- Off-grid inverter
- Battery bank
- Charge controller
Advantages:
- 100 percent energy independence.
- Works during power cuts
- Ideal for remote locations
- No electricity bills
Limitations:
- Low start-up price because of batteries
- No battery replacement after every 58 years
- Low power in case batteries are exhausted.
Best Suitable For:
- Remote villages
- Farmhouses
- Construction sites
- Areas that experience frequent blackouts.
- Hybrid Solar System
A hybrid solar system is a mix of the grid-tied and off-grid system. It is linked to the grid as well as battery backup.
How It Works?
- Electricity is produced using solar panels.
- Home loads will be first loaded by power.
- Too much power will recharge batteries.
- Additional energy is sent out to the grid.
- When power cuts occur, power is supplied by batteries.
Key Components:
- Solar panels
- Hybrid inverter
- Battery storage
- Net meter
- Grid connection
Advantages:
- Power backup during outages
- Net metering benefits
- Making effective use of solar energy
- Reduced dependency on grid
- Smart energy management
Limitations:
- More expensive than grid-tied system
- Complex system design
Best Suitable For:
- Houses experiencing a lot of power outages.
- Hospitals and offices
- Commercial buildings
- Top-end residential development.

Solar Power for House: Breakdown Cost in India
So now we are going to de-budget the true expense of installing solar energy into your home in component form.
1.Solar Panels Prices to your House.
The greatest portion of the total system cost is constituted by solar panels.
The Indian homes use solar panels in the following types:
- Monocrystalline (Higher efficiency, a little costly) panels.
- Polycrystalline panels (Inexpensive, a little lower efficiency)
India Solar Panel Price (2026 Estimates).
Panel Type Cost per Watt
For Monocrystalline ₹28 – ₹38
Polycrystalline ₹24 – ₹32
Example: Approximately 8-9 panels are needed to make a 3kW household solar panels system. Panel cost will be approx. ₹90,000 – ₹1,20,000 .Solar panels take up close to 45 to 50 percent of the system cost.
2. Home Solar Installation Cost of Solar Inverter.
The solar inverter takes DC power panels and transforms them into valuable AC power to your house.
Types of Inverters:
- String inverter
- Micro inverter
- Hybrid inverter (supports the battery)
Solar Inverter Price Range:
- Grid-tied inverter: ₹25,000 – ₹45,000
- Hybrid inverter: ₹45,000 – ₹90,000
An appropriate selection of an inverter is essential in effective solar power to use in the home.
3. Cost of Solar Energy Battery to Your Home.
The surplus energy of the sun is stored in batteries to be used during the night or power outages.
Common Battery Types:
- Lead-acid batteries (less expensive).
- Lithium-ion batteries (greater life and performance)
Battery Price in India:
- Lead-acid: ₹15,000 – ₹20,000 per battery
- Lithium-ion: ₹80,000 – ₹1,50,000
A common off-grid solar power house system can require 2-4 batteries making it much more expensive.
