Solar Photovoltaic

PV system, is a power system designed to supply usable solar power by means of photovoltaic's. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to change the electric current from DC to AC, as well as mounting, cabling and other electrical accessories to set up a working system.

ON Grid Application 

On Grid Solar System. The on-grid solar system also known as grid tie or connected solar system. ... If system is producing more power than is being consumed, the surplus is fed into the main electrical grid via solar net metering.

Net Meter

Net metering is a billing mechanism that credits solar energy system owners for the electricity they add to the grid. For example, if a residential customer has a PV system on the home's rooftop, it may

generate more electricity than the home uses during daylight hours. If the home is net-metered, the electricity meter will run backwards to provide a credit against what electricity is consumed

at night.

What is Net Metering

Net metering is the process through which you attain a “dual-benefit “by installing a solar power plant on the roof, open space, walls of the building to generate electricity.

Generated power is first used in the building as per the requirement and the surplus power is fed to the grid of utility.

Who can install

Consumers of electricity having minimum sanctioned load of 1.25KW and maximum of 12.50 MW who intend to generate their own electricity and desire to contribute towards environmental protection can install Solar PV plants on Roof-Tops/ Walls/Open area of Individual households, Industries,commercial establishments, institutions, residential complexes, Schools, Colleges, Hospitals, sheds,cold stores, govt. and semi-govt. buildings, etc.

What is the Procedure for Net Metering

1.Submission of Application

For installation of solar power plant the applicant has to register/apply online at anyone the sites with copy of latest electricity bill and available shadow free area at the top of roof/ walls/ open space within the compound.

Period of Time ::3 weeks

Approval For Installation

After verification, Discom will give online approval to the applicant for installation of required capacity Solar Power Plant.

• Period of Time: 120 days

Processing Fee & Signing of Agreement with Discom

The consumer intending to setup Roof Top solar power plant shall deposit the processing fee of Rs. 50 per KVA or part there of subject to maximum of Rs.10000 in the concerned DS/ Sub Division office of

Discom on first come first serve basis. The consumer shall also sign supplementary agreement with Discom.

Installation of Solar Power Plant

After approval from Discom, applicant will contact Medors to install solar power plant and submit online work completion report along with photograph of the system and single line diagram of the synchronizing and protection arrangements.

Installation of Bi-directional Meter

After receiving project completion report, Bi-directional meter would be installed at the premises of the beneficiary by Discom. For this, applicant has to deposit prescribed fee of Bi-Directional meter at Sub Divisional Office of Discom.

Release of Subsidy

After installation of Bi-directional meter the plant shall be treated as commissioned and the beneficiary will apply online for release of subsidy to SNA along with the work completion report duly verified by

Discom.

Banking Mechanism And Billing

Discom shall take energy meter readings for import or drawl and export or injection of power and work out the net energy flow quantum from or to the consumer. In case the net flow is towards the Discom i.e. the consumer has injected/exported the net surplus energy to the Discom system, such quantum will be treated as energy banked by the consumer with Discom in the current billing cycle.

Discom Tariff

The Energy Bill for import will be prepared as per the retail supply tariff as approved by the CERC for the category to which the consumer belongs. The energy exported to Discom from the rooftop Solar PV system shall be set-off against the energy imported from the Discom grid at the CERC approved retail supply tariff applicable to the particular consumer category.

MNRE Issues New Benchmark Costs for Rooftop Solar Projects for 2020-2021

August 03, 2020 Rooftop Solar 2 Comments

 

The Ministry of New and Renewable Energy (MNRE) has issued a notification with the latest benchmark costs for the installation of new grid-connected rooftop solar PV systems for the present financial year i.e. FY 2020-2021.

 

As per the notification, projects with a capacity of more than 1 kW and up to 2 kW, the benchmark cost has been set at Rs 43/W, or Rs 43,000 per kW.However, in the special category states – North-Eastern states, Uttarakhand, Himachal and the Islands – the benchmark has been set at Rs 47/W or effectively Rs 47,000 per kW Down Rs 12,000 per kW from the previous fiscal.

 

For projects with a capacity above 2 kW and up to 3 kW, the rate for general category states will be Rs 42/W and for special category states Rs 46/W. And for projects with a capacity above 3 kW and up to 10 kW the rate has been set at Rs 41,000 per kW (General) and Rs 45,000/kW (Special).

 

In the size category >10 kW and up to 100 kW, the benchmark has been set at Rs 38,000 per kW in the general category states. Down from Rs 48,000 per kW in 2019-20. In the special category states the rate has been lowered to Rs 42,000 kW from Rs 53,000 per kW in the previous fiscal.

 

Finally, in the >100 kW and up to 500 kW category, the benchmark has been set at Rs 36/W in the general category states.

 

Down from Rs 45,000 per kW in 2019-20. In the special category states the rate has been lowered to Rs 40,000 kW, down Rs 10,000 per kW from Rs 50,000 per kW in the previous fiscal.

 

 

The benchmark costs will be applicable for all letters of award (LoAs) to be issued or for the vendors to be empaneled after July 31, 2020.

 

The benchmark costs are inclusive of the total project costs, which include solar modules, inverters, the balance of systems, cost of civil works, installation, commissioning, transportation, and comprehensive maintenance for five years. The benchmark costs do not include net metering costs and battery back-up costs.

The MNRE also stated that the above-mentioned benchmark cost is indicative only. And that all participating Discoms under phase II of the rooftop solar programme will ensure that the rate is discovered through a transparent bidding process. The rates will be applicable for all LoAs to be issued/ empanelment of developers/vendors to be done after July 31, 2020, by the implementing agencies in States/UTs.
