Question 1

What is the life of a solar rooftop?

Accepted Answer

The lifespan of a solar rooftop system is 25 years. Solar panels come with a 25-year warranty, while inverters typically have a warranty of 5-12 years.

Question 2

Does a solar rooftop have high maintenance costs?

Accepted Answer

No, solar rooftops require minimal maintenance. Cleaning the panels 1-2 times a month is sufficient. Ikaya Earth also provides free maintenance support for the first five years.

Question 3

Can a solar project damage my roof?

Accepted Answer

No, Ikaya Earth uses non-penetrating structures and waterproofing solutions to protect your roof. Our installations meet global safety standards, ensuring no damage to your existing structure.

Question 4

Do I need to clean my solar panels?

Accepted Answer

Yes, cleaning 1-2 times a month is recommended. Use a soft nylon brush or sponge and avoid detergents or metal brushes. Clean the panels in the early morning or evening for safety.

Question 5

Can I install solar if my roof is not concrete?

Accepted Answer

Yes, solar panels can be installed on almost any roof type. If your roof is brittle or unstable, Ikaya Earth provides roof reinforcement solutions as part of the project.

Question 6

What is the maximum subsidy under PM Suryaghar Muft Bijli Yojna in Uttar Pradesh?

Accepted Answer

Under the PM Suryaghar Muft Bijli Yojna in Uttar Pradesh, the maximum combined subsidy for solar rooftop systems is ₹1,08,000 for systems of 3 kW and above. Here's the breakdown:
 • 3 kW, 4 kW, or 5 kW Systems:
    • Central Subsidy: ₹78,000
    • State Subsidy: ₹30,000
    • Total Subsidy: ₹1,08,000

Note: The subsidy amount remains the same for systems of 3 kW, 4 kW, and 5 kW, as ₹1,08,000 is the capped subsidy for these capacities.
These subsidies significantly lower the cost of solar installations, encouraging wider adoption of clean energy solutions.

Question 7

Can I get a subsidy on a hybrid solar rooftop?

Accepted Answer

Yes, subsidies are available for hybrid solar systems

Question 8

What is the difference between on-grid and off-grid systems?

Accepted Answer

• On-grid systems are connected to the grid, allowing you to export excess power.
 • Off-grid systems work independently and use batteries to store energy for backup.

Question 9

What capacity solar system should I install?

Accepted Answer

The system capacity depends on your energy consumption and sanctioned load. For example, a 3 kW system is ideal for a household with monthly consumption of 300-400 units.

Question 10

If my sanctioned load is 3 kW, can I install a 4 kW system?

Accepted Answer

No, you must first increase your sanctioned load from the discom to 4 kW before installing a higher-capacity solar system.

Question 11

Can I run AC on an on-grid solar rooftop system?

Accepted Answer

Yes, you can run as many ACs as you want on an on-grid solar system, but it depends on your sanctioned load from the electricity board, not your solar capacity. Since on-grid systems are connected to the grid, the electricity supply comes directly from the meter, ensuring you can power your appliances without limitations based on the solar system size. However, the solar system will help offset your electricity bill by generating energy that reduces your overall consumption cost.

Question 12

What happens to extra units generated?

Accepted Answer

Excess energy from on-grid systems is exported to the grid. You receive credits for this energy, reducing your electricity bill.

Question 13

How much space is required for installing a solar rooftop system in square feet?

Accepted Answer

You need approximately 50 sq. ft. of shadow-free area to install 1 kW of solar panels. For instance:
 • A 3 kW system requires ~150 sq. ft.
 • A 5 kW system requires ~250 sq. ft.
The exact space may vary depending on the type and efficiency of solar panels used, but these are standard estimates for most installations.

Question 14

How does a hybrid solar system work, and is it better for homes in Lucknow and Noida?

Accepted Answer

A hybrid solar system combines the benefits of on-grid and off-grid systems. It allows you to store excess power in batteries while also being connected to the grid. This ensures uninterrupted power during outages, making it ideal for areas with frequent power cuts, like some parts of Lucknow and Noida.

Question 15

Will installing a solar rooftop system increase the load on my roof?

Accepted Answer

Solar panels are lightweight and add minimal load, typically 10-15 kg per sq. ft. Modern installation techniques ensure that the roof's integrity remains intact, even on older structures.

Question 16

How long does it take to install a solar rooftop system?

Accepted Answer

The installation of a typical residential solar rooftop system (e.g., 3-5 kW) takes 2-5 days after approvals, depending on the complexity and site conditions.

Question 17

Can I monitor my solar system’s performance remotely?

Accepted Answer

Yes, modern solar inverters come with real-time monitoring systems. Using apps, you can track energy generation, usage, and savings directly from your phone or computer.

Question 18

Can I expand my solar capacity in the future?

Accepted Answer

Yes, most systems are scalable. You can add more panels and inverters as long as your roof has sufficient space and your sanctioned load supports it.

Question 19

Does weather affect solar power generation ?

Accepted Answer

Solar panels generate electricity even on cloudy days but at reduced efficiency.

Question 20

How can I protect my solar panels from damage during extreme weather?

Accepted Answer

High-quality panels are designed to withstand heavy winds, hailstorms, and extreme heat. Additionally, professional installation ensures panels are securely mounted to avoid damage.

Question 21

What happens if my solar panels generate more electricity than I consume?

Accepted Answer

If you have an on-grid system, the excess electricity is sent back to the grid through net metering. You’ll receive credits for this, which can reduce your future electricity bills.

Question 22

How do I choose the right solar system capacity for my home?

Accepted Answer

To choose the right system:
 • Calculate your monthly electricity consumption in kWh.
 • Match it with a solar capacity (e.g., a 5 kW system generates ~600 units/month).
 • Consult a professional to account for space, roof condition, and sanctioned load.
