Frequently Asked Questions
Everything you need to know before going solar with Karma-Tech
1. What is rooftop solar and how does it work?
Rooftop solar is a system where solar panels are installed on your roof to generate electricity using sunlight. The solar power generated is either used directly in your home or fed back to the grid to offset your electricity bill.
2. Will I really get ₹78,000 subsidy?
Yes! Under the PM Surya Ghar Muft Bijli Yojana, the Central Government provides up to ₹78,000 subsidy. In Odisha, there’s an additional State Subsidy of up to ₹60,000, depending on your system size and usage.
3. What’s the total cost of installing a rooftop solar system?
The cost depends on the size of the system. But you can start with less than ₹10,000 thanks to subsidies and EMI options. For example, a 2 kW system (ideal for small families) starts around ₹1.2-1.4 lakh before subsidy.
4. How much electricity can a solar system generate?
On average:
1 kW system generates 4 units/day
3 kW system generates 12 units/day
5 kW system generates 20 units/day
This can cover your lights, fans, fridge, washing machine, and even 1 AC.
5. How much can I save on my electricity bill?
With the right-sized system, you can reduce your electricity bill to ₹0. Most customers recover their investment in 4-5 years, and the system lasts for 25+ years.
6. Do I need batteries?
For grid-connected systems, batteries are optional. Your solar panels work during the day, and at night you use grid power. If you want backup during power cuts, a hybrid system with batteries can be installed.
7. Can I run my AC and pump on solar?
Yes! With the right size of solar panel system, you can run fans, lights, AC, washing machine, TV, fridge, water pump, and more.
8. What documents are required for subsidy?
You’ll need:
Recent electricity bill
Aadhar card
PAN card
Land/roof ownership proof
Our team will assist you throughout the application process.
9. What is the warranty on the solar system?
Panels: 25 years performance warranty
Inverter: 5–10 years (depending on brand)
Installation: Free service support for 1 year (extended AMC available)
10. How much space do I need on my roof?
1 kW system needs about 80–100 sq. ft
So for a 3 kW system, you’d need around 300 sq. ft of shade-free rooftop space.
11. Can I apply for a solar pump system?
Yes. We also install solar water pumps under subsidy for agriculture and household use. You can get a full system by paying just ₹20,000 with government support.
12. What if I generate more electricity than I use?
Any extra electricity you generate is exported to the grid. Your bill shows net usage, so if you generate more, you can earn credits from the electricity board.
13. How long does it take to install the system?
Once documents are submitted and approval is received, the entire system can be installed and activated within 10-15 working days.
14. Is EMI available?
Yes. We offer easy EMI options through our partnered banks and NBFCs so you can go solar without a heavy upfront investment.
