Solar energy is gaining popularity in the recent years as a sustainable option in both commercial and residential sectors. The Union Budget 2025-26 has increased funding for the solar power sector by ₹20,000 crore, up from ₹6,500 in FY25, as the government intends to concentrate largely on the rooftop solar scheme for installation of solar panels for home in India. There has been an increasing push for renewable energy, with the country aiming for 500GW of non-fossil fuel electricity by 2030. It currently stands at 209 GW. The rising electricity costs and the environment awareness has been the catalyst for this change.

If you are looking to install solar panels for home in India, you might want to know how much solar panel required for home, how much kilowatt required for home, and what is the cost of solar panels per kWh. This blog has covered it all for you! Let’s begin.

Are solar panels for home worth the investment?

Installing solar panels for home are an excellent way to reduce or even eliminate your electricity bills, sometimes providing up to 100% savings. Investing in them is not just an expense but a smart long term investment.

Typically, it takes around 5 to 7 years to recover the initial cost of installing solar panels for home, after which the electricity generated is free.

Besides the substantial savings, choosing solar panels for home is a step toward energy independence and a greener future.

How many solar panels are needed to run a house: A step-by-step guide

1. Calculate Monthly Energy Needs : Begin by assessing your household's average monthly electricity usage. Understanding your energy consumption is vital to determine how many solar panels for home installation you will need.

2. Estimate Solar Panel Capacity : Divide your monthly energy usage by the average monthly solar energy output in India, which is approximately 115 kWh. This calculation will give you the required kilowatt capacity for your solar panels for home use.

3. Determine the Number of Solar Panels : To estimate how many solar panels for home are required, divide the kilowatt capacity by the wattage of a single solar panel.

By following these steps, you can make an informed decision on how many solar panels for home you may need. Investing in solar panels for home not only reduces electricity bills but also helps in giving you worry free future.

How Much Kilowatt Required for Home? 1 kW, 3 kW, or 5 kW Solar Panels?

1 kW Solar Panels for Home

Perfect for small households, a 1 kW system can power a 2-3 BHK home. It typically supports basic appliances like one refrigerator, three fans, one TV, one laptop, and 4-5 lights. On average, this system can handle loads of up to 800 W regularly, making it a cost-effective choice for modest energy needs.

3 kW Solar Panels for Home

Ideal for mid-sized households, a 3 kW solar system generates approximately 12 units of electricity daily. This totals around 360 units per month or 3,600 units annually, which is sufficient for a family of 3-4 members. It comfortably powers everyday appliances, ensuring energy independence for medium energy users.

5 kW Solar Panels for Home

Suitable for larger families, a 5 kW system can generate enough electricity to meet most household requirements. It powers appliances such as lighting, fans, TVs, refrigerators, and air conditioners (used for a few hours daily) while catering to monthly consumption of around 600-800 units. It's an excellent option for homes with higher energy demands.

To decide on the right system for installing solar panels for home, you start by calculating your average monthly energy consumption. If your usage matches the output of a 3 kW or 5 kW system, it’s an efficient choice. However, for higher energy needs, larger systems like a 10 kW may be required, although they come at a higher cost. Smaller systems, on the other hand, may not be sufficient for homes with significant energy consumption.

What is the cost of a 3kW solar system for home in India?

The cost of a 3kW solar system for home in India varies depending on the type of system. On average:

• 3kW- 3kW On-grid solar system : ₹2,18,300 onwards* (with a subsidy of ₹78,000)

• 3kW- 3kW Off-grid solar system : ₹2,40,000 onwards* (subsidy not applicable)

• 3kW- 3kW Hybrid solar system : ₹4,50,000 onwards* (with a subsidy of ₹78,000)

PM Surya Ghar Muft Bijli Yojana: An initiative to encourage the adoption of solar panels for home

PM Surya Ghar Muft Bijli Yojana offers a subsidy of 60% of the solar unit cost for systems up to 2kW capacity and 40% of the additional system cost for systems ranging between 2 to 3kW capacity, with the subsidy capped at 3kW.

As per the official guidelines, the government provides a ₹30,000 subsidy for 1kW systems, ₹60,000 for 2kW systems, and ₹78,000 for 3kW systems or more for the installation of solar panels for home. This implies that the pre-subsidy costs of a solar system are approximately ₹50,000 for 1kW, ₹1,00,000 for 2kW, and ₹1,30,000 for 3kW.

Solar panels for home are a sustainable and efficient way to reduce electricity bills while contributing to a greener environment. Beyond the financial savings, solar panels for home require minimal maintenance and typically have a lifespan of 25 to 30 years.

The scheme makes installing solar panels for home an affordable one-time investment with long-term benefits for households, both economically and environmentally. Adopting solar panels for home is not only a step toward energy independence but also a meaningful contribution to sustainable living.

A checklist for installing solar panels for home

• 3kW- Review your electricity bills to gauge energy usage and costs; solar panels for home make sense if electricity rates are high.

• 3kW- Plan to stay at your home long-term, as solar panels for home take around 5 years to break even and last 20+ years.

• 3kW- Ensure your roof is in good condition; older roofs may need replacement before installing solar panels for home.

• 3kW- Check roof size, slope, and design—south-facing roofs with a 15–40° slope are ideal for solar panels for home.

• 3kW- Assess sunlight exposure; shade from trees affects solar panel efficiency.
