As solar adoption continues to grow across India, homeowners are increasingly asking one important question:

“Which solar panel size is best for my home?”

At Switch2Solar, we help customers choose the right solar solution based on electricity usage, roof space, subsidy eligibility, and long-term return on investment.

In this guide, we explain the latest solar panel sizes available in 2026, the difference between DCR and Non-DCR panels, and which option makes the most financial sense for Indian homes.

Understanding Solar Panel Size in 2026

Modern solar panels are now more powerful and efficient than ever before. Earlier, residential projects commonly used 330Wp or 450Wp panels. Today, high-efficiency panels such as:

• 600Wp DCR Solar Panels
• 640Wp Non-DCR Solar Panels

are becoming the preferred choice for residential and commercial rooftop projects.

At Switch2Solar, we currently supply:

600Wp DCR Solar Panels

Ideal for residential systems eligible for government subsidy.

640Wp Non-DCR Solar Panels

Best suited for larger systems where maximizing savings and reducing project cost is the priority.

What is DCR and Non-DCR Solar Panel?

DCR Solar Panels

DCR stands for Domestic Content Requirement. These panels are manufactured using locally produced solar appliances and modules as per Indian government guidelines.

Benefits of DCR Panels

• Eligible for Government Subsidy
• Supports “Make in India”
• Ideal for Residential Rooftop Subsidy Projects

Best Suitable For

• Homes planning to install systems up to 5.5kW
• Customers looking to maximize subsidy benefits

Non-DCR Solar Panels

Non-DCR panels may use imported solar cells and are generally more cost-effective for larger capacity systems.

Benefits of Non-DCR Panels

• Lower overall project cost for larger systems
• Higher wattage availability
• Better financial return for high-capacity projects

Best Suitable For

• Residential projects above 5.5kW
• Commercial and larger rooftop installations

Which Solar Panel is Better for Your Home?

Projects Below 5.5kW – Choose DCR Panels

For systems below 5.5kW, Switch2Solar recommends DCR solar panels because homeowners can significantly reduce the effective project cost through government subsidy benefits.

Why?

The current residential solar subsidy is capped at approximately:

₹78,000

This subsidy helps offset the slightly higher price of DCR panels, making them the smarter investment for smaller residential projects.

Recommended For
• 3kW Solar System
• 4kW Solar System
• 5kW Solar System

Projects Above 5.5kW – Choose Non-DCR Panels

For systems above 5.5kW, we generally recommend Non-DCR panels.

Why?

Although DCR panels qualify for subsidy, the subsidy amount remains capped. Beyond this capacity, the additional cost of DCR panels often becomes higher than the subsidy advantage.

This means:

• Non-DCR projects become more economical
• Lower cost per watt
• Better ROI for larger systems
• 1Rs excess per unit excess generation

Recommended For

• 6kW Solar System
• 8kW Solar System
• 10kW Solar System and above

Solar Panel Dimensions

Both our:
• 600Wp DCR Panels
• 640Wp Non-DCR Panels

typically come in a standard large-format size of:

8 Feet × 4 Feet

Important Considerations

Before installation, homeowners should evaluate:

• Roof shadow-free area
• Structural strength
• Panel layout planning
• Future maintenance access

Our Switch2Solar team provides complete site assessment and design support before installation.

A new program launched in February is offering 75 billion rupees ($9bn) of subsidies to incentivize the installation of grid-connected rooftop solar systems on an estimated 10 million houses. As far as possible, people can now power their own lights and fans with cheap electricity each time the sun is directly overhead, and sell surplus units — up to the amount they draw from other homes’ panels — to the grid for a small profit. After paying off any initial loans used to make the switch, some people may find that daytime electricity costs fall effectively to zero.

For good reasons Indian rooftops hold an enormous quantity of highly standardized energy: practically all are covered with concrete or aluminum slabs. If every house collected it using solar-power technology, India’s roofs would be close to generating 637 gigawatts (GW) at peak capacity under test conditions. That prompted India’s Prime Minister Narendra Modi last year to pledge five years of government support for another scheme encouraging homeowners’ associations in cities to build big solar arrays across common space atop apartment buildings.

With the increase in electricity prices, installing home solar panels has become a viable option. By using home solar panels, you can generate your own electricity and are less dependent on the grid. This leads to reduced power bills. The recurrent cost of power generation with solar panels is almost negligible and predictable while budgeting monthly expenses.

Solar panels also require very minimal maintenance costs when compared to other alternatives for generating electricity. They are designed to last for around 25 years and if stored properly; they provide long-lasting benefits, especially during times when power demand is high such as low voltage problems in summer or peak hours slots. Also, the Indian Government provides subsidies & deductions for panel installation making India easily adopt Solar Power.

Solar Power: Driving India’s Green Future

As the world turns to greener forms of energy to protect the environment, the country with the second highest number of coal-fired power plants after China – India – is showing it can be done. Shifting to renewable and clean solar power not only helps save 54 million tonnes (mt) of CO2 emissions, but it also raises living standards, affording villagers with better diets and children more education as well as tools for their crafts. One example is a village that recently became among India’s first net energy generators generating enough power so electricity was given free during peak summer days! The 6 MW ground-mounted solar installation, 15 MW storage system, and 1,300 rooftop photovoltaic panels generate about 6,332 kWh a day.

With 20 years of experience in clean energy, Fenice Energy is the force behind India’s solar boom. Solar trends in India are synonymous with India’s goal of a renewable future. In fact, for India’s green revolution, solar energy is becoming the dominant technology landscape of the future.

Key Takeaways

  • India’s solar capacity: Over 81 GW- a reflection of their renewable energy commitment.
  • Foreign investment: Proves the world has confidence in India’s solar industry.
  • Upcoming tenders: Focus on strengthening the solar infrastructure. Regional solar parks: Land will be provided to develop the solar projects
  • Strategic approach: Focusing on key states for solar power generation.
  • Fenice Energy’s role: Major in India’s retention of solar energy future with clean energy technology solutions.

India’s government policies and new projects have led to increased investment in solar power, making the country a leader in renewable energy.

Future Trends in Solar Energy

Solar Photovoltaic (PV) Segment

It is expected to rule the solar energy market as it directly converts sunlight into electricity by using semiconductor materials that are mostly silicon. Solar PV systems have scalability, and they can cater to increasing energy requirements especially required across regions having limited or less reliable grid infrastructure.

Global Growth

In 2023, annual installations of solar PV increased by more than 80% YoY to reach a grid-connected installed capacity of 417 GWdc. Governments in the US, Europe, and India have been engaged in diversifying their solar PV supply chain through policies like India’s Production Linked Incentive (PLI) scheme and the US Inflation Reduction Act (IRA) which are boosting domestic manufacturers at scale.

India’s Developments 

Installed 9.71 GW of solar PV in 2023, up by 15.4% from 2022. The target is to auction 40 GW of PV capacity per annum and the rapid development of the domestic supply chain is expected to boost PV growth. Supportive Policies: Governments across the globe provide financial incentives such as feed-in tariffs, tax credits, grants, and net metering programs to encourage solar PV installations. For example, Australia plans to generate 82% of its electricity using renewable sources including solar PV and wind by 2030.

Amongst the end-use applications, the utility sector is expected to have the maximum market share in the solar energy market during the forecast period.

Installing an On-grid PV system in Bangalore can help homeowners slash their electricity bills by a good margin. Solar rooftop panels in Bangalore allow users to generate their power and become less reliant on the grid. This transition from conventional energy not only saves money but also helps contribute to a cleaner environment by reducing dependence on fossil fuels.

Today, on the auspicious occasion of the inauguration of Sree Rama temple in Ayodhya. The Prime Minister has announced that the people of India should have their own solar roof-top system on the roof of their houses. The central government has launched ‘Pradhan Mantri Suryodaya Yojana’ with the target of installing rooftop solar on one crore houses. With the collaboration of Switch 2 Solar, the best Efficient Solar Panels in Bangalore will not only reduce the electricity bill of the poor and middle class but also will make India self-reliant in the field of energy. 

Prime Minister Narendra Modi on Monday (January 22) announced a scheme to electrify one crore households with solar electricity. This will be a new government scheme under ‘Pradhan Mantri Suryodaya Yojana’ seems to be a new attempt to help reach the target of 40 GW rooftop solar capacity.

The Rooftop Solar Programme, and why solar energy is important for the country. The scheme would help not only reduce electricity bills of the “poor and middle class”, but also push India’s goal of becoming self-reliant in the energy sector. Currently, Solar power has a major share in the country’s current renewable energy capacity, which stands at around 180 GW

The Ministry simplified the implementation and application process to increase the deployment of On Grid Solar rooftop projects. Customers only need to submit their electricity bill to the respective power provider company and like on-grid solar systems in Bangalore, we are famous for installing on-demand Bate Solar as per need and desire. Also, our priority focus is on installing Solar Rooftop panel in Bangalore to make every individual comfortable and enjoy the service without any tension on electricity bills.

Union government ministry has announced an increase in subsidy for rooftop solar projects which is very important news for those who have taken up solar installation services. Currently, there are different slabs and the new rates will be applicable for the undertaken project. As per the new notification central financial assistance will grant ₹18, 000 per KW for residential solar rooftop between 1-3KW capacities. With the revision of the grant any consumer applying for subsidy will be eligible for the subsidy. With Switch2Solar, every individual will get the best efficient solar panels in Bangalore to make their electricity more reliable than ever with added convenience.

The officials have revised the rates for rooftop solar projects between 3KW and 10KW from

₹ 7,294/KW to ₹ 9000/KW For special status the subsidy for residential rooftop projects between 1 to 3 KW stands at ₹ 20000 and for the project above 3 KW to 10 KW the subsidy will be 10000. IT also added that for the residential welfare association for common facilities up to 500 KW with a ceiling of 10 KW will give a grant of ₹ 9000/KW, and ₹ 10000 for special states.  In the North East some special states such rates are applicable including Sikkim, Uttarakhand, Himachal Pradesh, and UTs – Jammu and Kashmir (J&K). Ladakh, Lakshadweep, and Andaman & Nicobar Islands

The ministry stated that all future bids and bids which are scheduled to be closed after 15 days after the issue of the notice will be applicable for the new rates.  It also confirmed that the new rates will be applicable for all claims submitted in the National Portal for Rooftop Solar.  Get in touch with Switch2Solar, which provides Solar Rooftop panel in Bangalore to give the best insight to anyone looking to become a market leader in the rooftop solar industry.

With switch2solar being the buzzword these days, the Bangalore Apartments’ Federation (BAF) has taken a progressive step towards the installation of multiple rooftop solar panels. With the intent of reducing the load on the state power grid, the apartments have collectively reached out to Bangalore Electricity Supply Company (Bescom) seeking permission to install multiple residential rooftop solar panels. Switch 2 Solar has been serving the best on grid solar system in Bangalore for years to fit the solar industry. The connection with switch2solar will help reduce the peak-load demand, which will impact the effective management of the grid. The more such solar installation on a building the more energy can be added to the grid. BESCOM has come forward and shown its solidarity to this initiative which would result in surplus power.

However, guidance from the Karnataka Electricity Regulatory Commission (KERC) is needed before BESCOM can come to a final decision in this regard. Meanwhile, a BESCOM spokesperson said that BAF can reach out to KERC directly for detailed guidelines. The current scenario allows the resident welfare association(RWA) installation of Solar PV systems on an even rooftop only. However, apartments have several other broad areas, like the community hall building, gyms, or even parking spaces which can support the installation of solar grids. If this request is approved and solar panels are installed beyond the main roof, there will be an increased generation of power in each apartment building, resulting in less burden and a reduction in load shedding during peak hours.

This is indeed the call of this hour and a green measure for a sustainable environment.
