FAQ's

solar power cheaper than diesel/grid power?

Rooftop solar power is much cheaper than power from diesel generators. Solar PV generates power at a cost of about Rs. 7-8.5/unit while diesel generates power at about Rs. 16/unit. Whether solar is cheaper than grid power depends on your current tariff. Solar power is cheaper than grid power for many consumers but in some cases, such as consumers paying domestic tariff, solar power maybe more expensive than grid power.

Will I get power during a power failure?

GreenAlpha provides inverter that can use other sources of power than the grid as a reference voltage and continue to function even when the grid is down.eo.

What is the warranty on the solar panels?

Our solar panels have a 25-year factory .All equipment is covered during the term of the lease, and you’ll also receive maintenance and output monitoring for free. We guarantee against any generation shortfalls.

What happens if there is a drastic change in the grid pricing?

Typically, our tariff is pre decided and unaffected by grid pricing. But we may peg our tariff to the grid if the client demands. This will mean that the tariff will change in tandem with the grid pricing.

How much does a rooftop solar PV system cost?

A rooftop solar PV system costs approximately Rs. 1,00,000/kWp (Kilowatt peak) including installation charges but without batteries.

What are the permissions required for putting up a rooftop solar PV plant?

Typically, permissions are not required to set up rooftop installations with capacity less than 10 KW. If the capacity exceeds 10 KW, the main approval required is for the developer to get permission from the nearest substation.

I have a manufacturing unit that operates for 9 months a year and is under maintenance for the remaining.

The capacity of the plant will be decided keeping in mind the minimum consumption at any time of the term. Once agreed upon, the billing will be done on the generation of the plant..

What if the plant does not perform as calculated?

Upon intimidation of the issue, our instant response team will address to it on-site within 48 hours. The performance will be restored to the calculated figures within seven days of nonperformance.

TECHNICAL

Is my building a good candidate for solar power?

If you are a corporation or Real Estate Investment Trust with multiple sites, a utility looking to implement a renewable program for your ratepayers, or a government institution, you may be a good candidate. If you are experiencing high or volatile energy costs, are using a lot of high-peak energy, are faced with clean energy mandates, or want to reduce your dependence on fossil fuels, you are probably a great candidate for our solar energy services.

How much roof area do I require to install a rooftop solar PV system?

The area required by a rooftop PV plant depends on the extent of shade-free space available and solar panel efficiency. Solar PV system typically requires 100-130 sq ft. (about 12 sq m.) of shade free roof area per kW of capacity at current crystalline panel efficiency level.

What if my site is taken over/sold, demolished or goes under refurbishment?

The system will be transferred to the new location upon request from the client. The cost of the transfer will be borne by the client.

Is this the right time to enter a long-term agreement?

Solar prices have come down drastically with the recent advancement in technology. With solar tariff already lower than grid tariff, the earlier you start, the more you save.

How much electricity does a rooftop solar PV system generate?

The amount of electricity generated by a rooftop solar PV plant depends on the location, orientation of the roof, panel efficiency and ambient temperature. As a rule of thumb, a 1kW plant will generate about 4kWh (units) of electricity a day on average in a year.

If my roof is shaded, does that make a difference?

Shade reduces the amount of electricity your system can produce. The panels operate independently, so if one panel is in shade during part of the day, the others still generate electricity. Our installers will design your system for maximum sun exposure, but sometimes a roof may be too shady to make solar feasible.I am text block. Click edit button to change this text.

How do I get charged for using solar power from my rooftop?

GreenAlpha installs certified meters to measure the system generation. You will be charged on the power generated at a pre decided tariff.

OPERATIONAL

What are the various components of a rooftop solar system?

A rooftop solar PV system primarily comprises of solar PV modules (panels), inverters, and mounting structures. If battery backup is required batteries and charge controllers would also be integrated with the system.

What are my options for financing a solar system?

You can always buy your solar system outright, but with third-party financing, we offer a Rs. 0 (zero) down-payment model. You can also finance a solar system with a loan/debt.

How will my building look?

Your solar roof will look great! We work with our manufacturers to make our panels sleek and elegant. The frames are painted with automotive-grade paint, while our mounting structures blend them into your roof. We also make sure that wiring and other components are hidden from view.

What happens if my solar power provider winds up operations?

On any such occurrence, the client will assume full rights over the assets and enjoy solar power generation for its lifetime.

What are the constraints in generating power from rooftop solar?

  • Some limiting factors are:
  •  Solar power is generated only during the daytime on non-rainy days
  •  Solar power may not handle the heavy starting currents required by    heavy machinery
  •  The output of the solar plant varies as the sun moves across the sky,  and as clouds move across the sun.

How much maintenance is required?

Solar Systems generally require very little maintenance. Spraying them down with water once a month to remove excessive dirt and debris is typically all that is needed. In addition, our online monitoring system provides a 48-hour response to any type of non-performance.

What happens to the plant after the PPA is over?

The plant’s assets are transferred to the client at no-cost at the end of the PPA tenure.

Will there be any damages to my roof? It already has some issues.

Our site survey team examines your roof for system installation. Once declared fit, we guarantee a hassle-free installation and operation. There will be no damage to your property.
