This articles discusses about how you can generate your own power and avail government subsidy under SECI’s(Solar Energy Corporation of India) 500 MW Grid Connected Roof Top Solar PV Scheme
“Rooftop Solar” (RTS)
The concept of rooftop solar is based on the scale of the PV(photovoltaic) plant rather than the fact whether it is situated on a roof/ terrace or not. Hence, the definition of RTPV should also include small plant on the ground up to the capacity of 100 kW. Generally PV rooftop projects are relatively small (especially when compared to solar parks, haveng hundreds of MW of capacity.
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.
Subsidies available from multiple channels for setting up Rooftop PV projects:
a) 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/)
b) 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. Interested consumers may contact their respective SNAs for more details.
Models for implementation of Rooftop PV systems by SECI
Currently, SECI implements the rooftop scheme under two models:
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).
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. In this case, the developers are selected through a tariff-based reverse bidding (in phase IV).
How to Apply:
Individual household consumers can get off-grid rooftop systems installed on their roofs through MNRE channel partners to avail government subsidy. The list of MNRE channel partners can be found at http://mnre.gov.in/file-manager/UserFiles/list-of-Accredited-Channel-Partners-Rooftop-Grid-connected.pdf .
For setting up grid-connected systems in select cities/states that are being covered under SECI Large-scale Grid-connected Rooftop PV programme (Phase IV), consumers may contact any of the developers selected by SECI. The list of shortlisted developers is available at http://seci.gov.in/content/innerpage/grid-connected-rooftop-pv.php .
For setting up grid-connected systems in other areas, consumers may contact the respective State Nodal Agencies to find out if the same is permitted in their area.
