Frequently Asked Questions (FAQs) – Luminor Solar

Here are the most common questions we get from customers about solar panel installation, costs, benefits,
and government subsidies in India.

General Questions About Solar Energy

Do solar panels work during cloudy or rainy days?

Yes, but their efficiency is reduced. Solar panels can still generate power on cloudy days, though at a lower output compared to full sunlight. A battery storage system can help provide backup power.

Can I run my entire home or business on solar power?

Yes, but it depends on your energy consumption and system size. A properly sized solar panel system with battery backup can power your entire property.

Is solar power suitable for all locations in India?

Yes! India has abundant sunlight throughout the year, making solar energy ideal for homes, businesses, and agricultural applications. However, efficiency depends on factors like roof space, sun exposure, and shading.

How do solar panels work?

Solar panels convert sunlight into electricity using photovoltaic (PV) cells. The electricity generated can be used immediately, stored in a battery, or sent back to the grid through net metering.

Solar Installation & System Setup

Can I install solar panels on any type of roof?

Yes! Solar panels can be installed on flat roofs, sloped roofs, tin sheds, and even ground-mounted systems. Our team assesses your space and suggests the best installation type.

Do solar panels require a lot of maintenance?

No! Solar panels require minimal maintenance. Regular cleaning (every 3-6 months) to remove dust and dirt helps maintain efficiency. Inverters and batteries may need periodic servicing.

How long does it take to install a solar system?

A standard residential solar installation takes 1-3 days, while commercial and industrial installations can take up to a few weeks depending on size and approvals.

How much roof space is needed for solar panels?

A typical 1 kW solar system requires about 100 sq. ft. of shadow-free space. A 3 kW system needs around 300 sq. ft., and larger setups require more.

Cost, Financing & Government Subsidies

How long does it take to break even on a solar investment?

Most residential solar systems have a payback period of 4-6 years, while commercial and industrial setups can recover costs in 3-5 years, depending on electricity usage.

Is financing available for solar installation?

Yes! We offer:
✅ Easy EMI Options through partner banks
✅ Solar Loans with low interest rates
✅ Pay-as-you-go models for businesses

What subsidies are available for solar in India?

Under the PM Surya Ghar Yojana (Rooftop Solar Subsidy Scheme), you can get up to 40% subsidy for residential solar installations:

  • Up to 3 kW – 40% subsidy
  • Above 3 kW up to 10 kW – 20% subsidy
  • Above 10 kW – No subsidy, but net metering benefits apply

Commercial and industrial setups currently do not receive subsidies but can avail tax benefits and depreciation incentives.

How much does a solar system cost in India?

The cost depends on the system size and components:

  • 1 kW Solar System – ₹50,000 to ₹70,000
  • 3 kW Solar System – ₹1.5 Lakh to ₹2 Lakh
  • 5 kW Solar System – ₹2.5 Lakh to ₹3.5 Lakh
  • 10 kW Solar System – ₹5 Lakh to ₹7 Lakh

Government subsidies and financing options can reduce costs further.

Net Metering & Battery Storage

Can I add batteries to my solar system later?

Yes! You can start with an on-grid solar system and later upgrade with solar batteries for backup power.

What’s the difference between on-grid and off-grid solar systems?
  • On-grid (Grid-Tied) Solar – Connected to the electricity grid, uses net metering. No battery required.
  • Off-grid Solar – Works independently with a battery storage system for backup.
  • Hybrid Solar – A mix of both, using the grid + battery backup.
Can I go completely off-grid with solar?

Yes, but you’ll need a solar battery backup system to store power for nighttime or cloudy days. Off-grid systems are ideal for remote areas without grid connectivity.

What is net metering, and how does it work?

Net metering allows you to sell excess solar power back to the grid. Your electricity meter records how much power you send to and take from the grid, and your electricity bill is adjusted accordingly.

Warranty, Lifespan & Support

Does Luminor Solar provide after-sales support?

Yes! We offer lifetime technical support, regular maintenance checkups, and quick service assistance for any issues.

What happens if my solar system stops working?

We provide full service & support, including:
✅ Remote monitoring to track performance
✅ On-site servicing & repairs if needed
✅ Annual maintenance plans for long-term efficiency

What warranties do I get with my solar system?

✅ Solar Panels – 25 years performance warranty
✅ Solar Inverters – 5 to 10 years manufacturer warranty
✅ Batteries – 3 to 7 years warranty (depending on type)

How long do solar panels last?

High-quality solar panels have a lifespan of 25+ years, with performance warranties ensuring at least 80% efficiency after 25 years.
