Many middle class families in India are now installing solar panels on their rooftops to reduce electricity bills. This move also helps protect the environment. Once you invest in solar panels, you can recover the cost within a few years and then enjoy low cost or completely free electricity for a long time. With rising electricity prices and government subsidies, rooftop solar has become a much more affordable option than before.
How Much Capacity Does Your Home Need?
The solar sector in India is growing fast and the government is also promoting household solar installations. According to industry experts, families living in urban areas with monthly electricity consumption of about 300 to 500 units need a rooftop solar system of 3 kilowatts to 5 kilowatts. Usually, a 1 kilowatt solar system in India can produce about 1,400 to 1,500 units of electricity per year. However, this figure can change slightly depending on the city, weather, and sunlight availability.
How Much Electricity Does Each System Generate?
Based on this calculation, a 3 kilowatt system can produce about 4,200 to 4,500 units of electricity every year, while a 5 kilowatt system can generate around 7,000 to 7,500 units. In states where domestic electricity rates are between ₹7 to ₹10 per unit, this saving becomes quite significant.
For example, if a family uses about 400 units of electricity per month, their annual electricity bill can reach ₹40,000 to ₹60,000. Add the yearly increase in electricity rates and the same expense over the next 25 years can exceed ₹10 lakh. In such cases, a solar system provides significant financial relief over the long term.
What Subsidy Does the Government Provide?
Earlier, the biggest challenge in installing a solar system was its initial cost. But now, subsidy schemes from central and state governments have reduced this burden considerably. Under the Pradhan Mantri Surya Ghar Yojana, the central government provides subsidies up to ₹78,000 for domestic rooftop solar systems.
Many state governments also provide additional help to those installing solar panels. In Uttar Pradesh and Delhi, you can get an additional subsidy of up to ₹30,000. In some states like Assam, this support reaches up to ₹45,000. This has made it much easier for middle class families to install solar systems compared to earlier.
What is the Installation Cost?
Installing a 1 kilowatt solar panel costs between ₹55,000 to ₹75,000 before subsidy. After subsidy, this cost reduces to ₹25,000 to ₹45,000. For 3 kilowatts, the amount of ₹1,65,000 to ₹2,10,000 reduces to ₹87,000 to ₹1,32,000.
Additionally, installing a solar rooftop of up to 5 kilowatts costs ₹2,75,000 to ₹3,50,000, which reduces to ₹1,97,000 to ₹2,72,000 after subsidy.
When Does the Investment Pay Back?
According to solar companies and energy experts, the cost of most domestic rooftop solar systems gets recovered in about 4 to 6 years. This is called the payback period. The time it takes for the initial investment to return through savings in electricity bills is the payback period. After this, solar panels continue to provide electricity at low cost for the next 20 to 25 years.
Most good quality solar panels last about 25 years or more, although their electricity production capacity decreases slightly over time.
Quality Matters for Real Benefits
The real benefit of a solar system comes only when the installation quality is good. Experts say that choosing only the cheapest system is not the right decision. Customers must check that the solar modules being used are included in the government's ALMM (Approved List of Models and Manufacturers).
Besides this, the experience of the installation company, structural strength, wiring quality, and after sales service are also very important. Poor installation can reduce electricity production and may lead to problems like leakage or rust in the future.
Choosing the Right Size
Choosing the right system size is also very important. Installing a system larger than needed can unnecessarily increase costs, while installing a smaller system will not give you full savings. Therefore, experts advise that before installing a solar system, you must analyze at least the last one year of electricity bills. This helps understand what your actual electricity need is and you can choose a system of the right capacity accordingly.
Does Solar Work During Rainy Season?
Many people wonder whether solar panels work during monsoon or cloudy weather. According to experts, electricity production does reduce during the rainy season, but the total annual electricity production capacity is estimated keeping these conditions in mind beforehand. The extra electricity production during summer when there is more sunlight compensates for the reduction during monsoon.
Protection Against Rising Electricity Rates
A big advantage of rooftop solar is that it provides protection against rising electricity rates in the future. Generally, electricity prices keep increasing over time, but once a solar system is installed, your home's electricity needs start getting fulfilled by your own generated electricity. This reduces dependence on electricity bills and the ever increasing electricity rates cannot disrupt your budget.
Installing solar panels on your rooftop is not just an environmentally friendly decision but also a smart financial move. With government subsidies and falling installation costs, this is the right time to switch to solar energy.
