5. How much area is required for a 1 kW rooftop Solar PV system?
A 1 kW rooftop system generally requires 12 sq. metres (130 square feet) of flat, shadow-free area (preferably south-facing). Actual sizing, however, depends also on local factors of solar radiation and weather conditions and shape of the roof
6. What subsidies/capital supports is available from the Government?
Subsidies are available from multiple channels for setting up Rooftop PV projects.
Subsidy/Support from Central Government through MNRE: For systems upto 100 kWp in size, upto 15% subsidy can be availed with the help of MNRE-empanelled channel partners. For systems of sizes 100 kWp-500 kWp, subsidy can be availed through Solar Energy Corporation of India. (For more details, please visit http://www.seci.gov.in/content/)
Subsidy/Support from State Government through State Nodal Agencies (SNAs): Subsidy support is also available in various states. The percentage of subsidy varies according to the state policies.
7. What are the models for implementation of Rooftop PV SYSTEM?
Currently, SECI implements the rooftop scheme under two models:
a) CAPEX Model: Here, the entire system is owned by the rooftop owners. Responsibility of O&M for the system lifetime (25 years) is also with the rooftop owner. Developer is responsible for installing the system and initial 2 years O&M. In this case, the developers are selected through a system cost-based reverse bidding. Selected bidders are offered 30% subsidy on the system cost (exclusive of taxes).
b) RESCO Model: Here, the entire system is owned by the developer. Responsibility of O&M for the system lifetime (25 years) is also with the developer. Rooftop owners may consume the electricity generated, for which they have to pay a pre-decided tariff on a monthly basis. Excess generation may be exported to the grid, subject to availability of requisite state regulations.
8. How the net metering is done in case of rooftop solar projects?
Net metering allows electricity meter to spin forward when electricity flows from the grid into your building, and backward when your system produces surplus electricity that is not immediately used. Your excess electricity is “banked” on the utility grid. Metering helps to measure the solar gross generation, consumer load consumption, export and import to and from the Grid apart from measurement of AC system voltages and currents, frequency etc. As per the guidelines of CERC, the metering arrangement requires to accommodate DG sets and/or battery inverter etc.
9. How much will cost for a rooftop solar PV system. How about its economics?
The rapid decline in the solar PV has made the rooftop attractive proposition to the consumers. Solar roof-top system is an efficient solution to diesel generators as it reduces the operating costs of generating electricity. The power provided is uninterrupted and supplied throughout the life of the project. On an average, per unit cost with a diesel generator is Rs 15/- while the cost of solar rooftop system backed is Rs 11/unit. While the initial cost of installation of diesel generator is low as compared to solar rooftop for the same size, the operational cost of diesel generator turns out to be a lot more than that of solar roof-top. With solar rooftop system, one can save the cost of transportation, pilferage and storage of diesel.
10. Is rooftop solar power cheaper than diesel/grid power?
Rooftop solar power is much cheaper than power from diesel generators (Rs. 20/unit) and grid in most states in India today
11. Is my building suitable for the solar power?
If you are a corporation or Real Estate Investment Trust with multiple sites, a utility looking to implement a renewable program, 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.
12. 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.
13. How much does a rooftop solar PV system cost?
A rooftop solar PV system costs approximately Rs. 90,000- 1, 00, 000/kWp (Kilowatt peak) including installation charges but without batteries.
14. 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.
15. What are the constraints in generating power from rooftop solar?
Some limiting factors are:
A. Solar power is generated only during the daytime on non-rainy days
B.Solar power may not handle the heavy starting currents required by heavy machinery
C. The output of the solar plant varies as the sun moves across the sky, and as clouds move across the sun.
16. What are the permissions required for putting up a rooftop solar PV plant?
Typically, the only permission required is from the state utility service company. In solar leasing model, Solar Energy procures all the required permissions.
17. 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.
18. 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.
19. 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.
20. 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.
21. 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.
22. I have a manufacturing unit that operates for 9 months a year and is under maintenance for the remaining. How would you account for the additional power generated?
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.
23. 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.
24. What happens if there is a drastic change in 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.
25. What if there are major advances in the solar technology in the future? 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.
26. 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.
27. What happens if there is future roof repair?
An appreciable repair work may affect the generation for that period of time. But the overall functioning of the plant will remain unaffected.
28. 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 non-performance.
29. How total cost of system is segregated?
Note 1: The above prices are for components from Tier 1 manufacturers with 5-year manufacturer’s warranty. In addition the PV modules have output warranty of 90% of rated capacity for the first 10 years and 80% of rated capacity for the next 15 years.
Note 2: We have not considered battery backup as that can alter the economics significantly depending on the extent of battery backup (autonomy) required. Not only do batteries add to the initial cost, recurring maintenance, and replacement expenditure, the energy loss on charging and drawing from the battery also adds to the cost of power. A battery backup could add significant costs to the above system.
Note 3: We have not considered Thin-Film modules as they require more installation area for the same capacity as crystalline modules and are therefore not preferred for rooftop installations where the space is usually a constraint.
