Solar Subsidy and Government Schemes
To achieve its 100 GW solar mission, Government has decided to revamp the Solar Subsidy and Government Schemes in Phase-II of Govt Of India Rooftop Solar Power Plants Mission program.
The Ministry of New and Renewable Energy has proposed SRISTI — Sustainable Rooftop Implementation for Solar Transfiguration of India — the new scheme to incentivize and encourage the installation and commissioning of roof top solar power plant projects across India.
The recently proposed new Scheme would integrate DISCOMS Utility as Nodal center and implementing agency in Phase-II of Govt of India Rooftop Solar Power Plants Mission program under CFA from MNRE.
An official statement said, “The concept, once approved, shall serve as the basis of revised scheme of MNRE for solar rooftop in Phase-II and will replace the Cabinet Committee on Economic Affairs note that has been submitted to cabinet since April this year.”
Unlike earlier Pahse-I, the proposed scheme will integrate Discoms as an implementing agency in Phase-II of rooftop solar scheme, the statement added. State Nodal Agency (SNA) have been playing a pivotal role as implementation agency in the Phase I.
The newly introduced proposed scheme would aims to achieve a national solar rooftop target of 40 GW till 2021-2022.
It is also proposed that a Central Financial Assistance will be provided only for installation of roof top solar plants in residential sectors and not for Institutions & NGOs.
The residential users may like to install the solar power plant of capacity as per their own requirement and as per the respective State Electricity Regulatory Commission regulation. However, it may be noted that, the subsidy support would be admissible and limited up to 5 kWp capacity of plants only.
The solar generation incentive towards subsidy to the residential sector would be capped at Rs.18,000 per kW calculated at benchmark cost of Rs.60,000 per kW.
The incentive to Discoms for social, institutional, government sectors, commercial and industrial sector it would be capped at Rs.5,500 per kW calculated at benchmark cost of Rs.55,000 per kW.
The total incentive for the residential sector stands at ₹9,000 crore for 5000 MW of installations. The incentive to Discoms would be capped at Rs.14,450 crore for 35,000 MW of roof top solar power plant installations.
The total financial outlay is Rs.23,450 crore for 40,000 MW of roof top solar installations.
While clearly mentioning the sector wise targets, the new proposal said that Commercial and industrial sector woud set up 20,000 MW, the government, Residential, Social and the Institutional sector will set up 5,000 MW each
Super or Raised Structure for Rooftop Solar Power Plants
Basically Super or Raised structures are decided by a solar expert or solar power plant designer to ascertain 100% daylight upon installed solar panels. Some time upon inspection of rooftop of the consumer the Solar Expert finds that the installation will be affected adversely due to the shadow hence needs Raised or Super Structure. Space constraints is another reason for designing a solar power plant with Raised or Super Structure. There has been instances that customers do not want any kind of drilling or fixation work on their rooftops, in such scenario, the Solar Engineers decide to use raised or super structure for installation of solar power plants.
Designing of Super or Raised Structure for Rooftop Solar Power Plants
Many instances the solar discipline terrain is uneven and requires variable leg size to attain the extent installation and keep away from the shading of 1 desk over one other desk. It turns into essential if the liner shading shouldn’t be considered whereas designing the differential heights of the desk. Selection of basis can be one of many necessary components for the construction design and structure. Where ever excavation/ drilling is feasible, concrete construction are really helpful, nevertheless, a few of the challenge developer use ramming slightly than concrete construction to avoid wasting money and time. Rammed buildings are extra liable to corrosion and life expectancy for 20 years turns into essential. The buildings vertical member ought to be designed in such a method that they will accommodate variability in top from one desk to a different desk.
Flat roof solar installation This is the best methodology of installation of solar panels on the roof of the residential or industrial buildings. Flat roof solar PV system installation supplies flexibility for orienting the solar panels at particular angle to get the utmost publicity to the solar.
The solar panels are held collectively utilizing any of the next three techniques
- Ballasts or weights: These are appropriate in low wind zones. Instead of bolting the solar panels on the roof, weights are used to carry them in an array.
- Mechanical attachment: Solar panels are mounted on the roof utilizing steel beams. The steel buildings can maintain the solar array positions even in windy zones.
- Hybrid mount: This approach uses each ballasts and beam to carry the panels collectively and cling to the roof.
Pitched roof solar installation –This sort of solar power installation is made on the angular roof. This approach is advanced as a result of the solar panels must be held intact within the inclined floor of the roof.
Ground-mount solar installation –Some buildings are usually not appropriate for installation of solar panels due to their location, solar publicity areas, and so forth. In such circumstances, the place the land space is ample, ground-mounting of solar panels may be executed. This installation sort normally includes steel and concrete buildings to repair the solar panels on and above the bottom.
Installation of Super or Raised Structure is finally decided by the Site Survey
One of the necessary steps in going solar is site survey by solar installation companies. By taking a look at varied parameters like your geographical location, house availability, wind depth and so forth, solar power suppliers are capable of decide the appropriate sort of solar installation. Hence, it is smart to on-board a solar energy company which is supplied with the correct of technical experience to suggest an optimum solar answer.
