About Phase-II of Grid Connected Rooftop Solar Programme

Ministry of New and Renewable Energy (MNRE), Government of India has launched the Phase-II of Grid Connected Rooftop Solar Programme that provides a subsidy for installing rooftop solar systems. The programme is being implemented through electricity distribution companies and provides a subsidy for the household owner and Group Housing Societies to set up solar systems on the rooftop of their residence/residential campus. 40% subsidy will be provided for installing a rooftop solar system of up to 3kW capacity; 20% subsidy is available for installing a rooftop solar system beyond 3kW and up to 10kW capacity; 20% subsidy will be provided for Group Housing Societies/Residential Welfare Associations for installations up to 500 kW (at 10 kW per house) for common facilities. Click Here to study the Operational Guidelines on implementation of Phase – II of Grid Connected Rooftop Solar Programme. Note: Subsidy benefit from MNRE is available for the residential sector only.

Why should I install a Rooftop Solar System?

The solar rooftop system is a photovoltaic system that employs solar panels on the rooftops of the buildings which convert solar energy to electricity. The electricity generated caters to your internal energy requirements. By Installing a Rooftop Solar System you can: Reduce your electricity bill. Make effective use of the idle rooftop area. Contribute to sustainability and ensure the reduction of carbon footprint. Avail government subsidies and subsidized credit options Ensure maximum efficiency with minimal maintenance. You may install a rooftop solar system by contacting your local electricity distribution company or click the button ‘Install a Rooftop Solar System’ below.

What are the major types of solar PV modules?

There are three major types of solar PV modules. Mono-crystalline Poly-crystalline (also known as multi-crystalline) Thin-film Each solar PV module type has its own unique features. These PV modules also vary based on how they’re manufactured, their appearance, performance, costs each are best suited for. Mono-crystalline and Poly-crystalline solar PV modules Both mono-crystalline and poly-crystalline solar PV modules have cells made of silicon wafers. To build a mono-crystalline or poly-crystalline module, wafers are assembled into rows and columns covered with a glass sheet, and framed together. Poly-crystalline cells are square-shaped whereas mono-crystalline cells are square with missing corners. While both of these types of solar PV modules have cells made from silicon, mono-crystalline and poly-crystalline modules vary in the composition of the silicon itself. Mono-crystalline solar cells are cut from a single, pure crystal of silicon. Alternatively, poly-crystalline solar cells are composed of fragments of silicon crystals that are melted together in a mold before being cut into wafers. Mono-crystalline modules typically have the highest efficiencies and power capacity. Thin-film solar PV modules Unlike mono-crystalline and poly-crystalline solar PV modules, thin-film modules are made from a variety of materials. The most prevalent type of thin-film solar module is made from cadmium telluride (CdTe). To make this type of thin-film module, manufacturers place a layer of CdTe between transparent conducting layers that help capture sunlight. This type of thin-film technology also has a glass layer on the top for protection. Other materials used to manufacture a thin-film PV module are amorphous […]

Trainings

Lecture number 01 – Introduction to the PV sector The goal of this lecture is to provide basic information which is necessary to understand energy generation, especially in the context of solar PV systems.  Chapter 01 – What are the energy sources? You will learn about major differences  between energy sources: https://wp.me/pafmKT-wT Chapter 02 – What renewable energy is? You will understand why it is important use renewable energy sources and avoid use of fossil fuels, what does it mean energy potential and what would be the grow scenario of PV technologies (and as a consequence market potential). https://wp.me/pafmKT-xT Chapter 03  –  What is photovoltaics effect and how solar cells work? Under this chapter you will learn about the photovoltaics effect and working principle of a solar cell. https://wp.me/pafmKT-zO Chapter 04  –  What are the common types of Solar Photovoltaic (PV) installations?  In this chapter, you will learn about various types of Solar PV installations and their working principle. https://wp.me/pafmKT-y0 Chapter 05 – What are the types of metering configurations available for Solar PV Installations?

What are the solar rooftop business models?

1/1 The two main solar rooftop business models: CAPEX RESCO One major difference between the two business models lie in the investor; for CAPEX  the capital expenditures are done by the rooftop owner and for RESCO capital expenditures are done by the third party. Let us look further into the two business models: Capital Expenditure (CAPEX) The owner of the plant is the rooftop owner The rooftop owner is responsible for the financing, installation and O&M The responsibility of the O&M primarily lies with the rooftop owner; however, there is an agreed period between the developer and the owner when the developer provides the O&M service The rooftop owner can export the surplus energy to the utility grid which will be adjusted in the electricity bill                             Renewable Energy Service Company (RESCO) Under the RESCO model, the developer finances, installs, operates and maintains the rooftop solar power plant. An agreement is signed between the developer and the rooftop owner to decide on the tenure until when power purchase will be done by the rooftop owner. The rooftop owners consumes the electricity generated for which they have to pay a pre-decided tariff to RESCO developer on a monthly basis for the tenure of the agreement. Although ownership lies primarily with the developer, the transfer of ownership is possible after the time period as agreed upon; similarly, the responsibility of O&M can also be transferred from the developer to […]

What is Photovoltaics?

1/1 Photovoltaics is the direct conversion of light into electricity that occurs naturally in certain types of material, called semiconductors that exhibit a property known as the photoelectric effect that causes them to absorb photons of light and release electrons. Electrons in these materials are freed by solar energy and can be induced to travel through an electrical circuit. In most cases, the semiconductor material is used to manufacture a solar cell. Solar cells are primarily made up of silicon which absorbs the photons emitted by Sun. When sun ray’s strikes the solar cell, electrons are knocked loose from the atoms in the semiconductor material. If electrical conductors are attached to the positive and negative sides, forming an electrical circuit, the electrons can be captured in the form of electric current called electricity. A number of solar cells electrically connected to each other and mounted in a frame is called a photovoltaic module. The working of a solar cell is well explained in the video by SciToons – Brown University, below. Video by: SciToons – Brown University

BRPL Solar City Initiative

The BRPL rooftop program is a “utility anchored rooftop program” in the residential sector being hosted by a power distribution company in India. Through this program, BRPL plans to create a platform to catalog and aggregate all interested rooftop consumers in its distribution jurisdiction, starting with single-point delivery consumers in Dwarka and the solar rooftop vendors/integrators who are empanelled by IPGCL, GoNCTD / SECI/MNRE. The program is proposed to be run in line with DERC Net Metering Regulations 2014 and guided by Delhi Solar Policy 2016, aiming to maximize the utilization of solar rooftop potential in Delhi. The program is to be launched under the alias of the BRPLSolar City Initiative. The aim of the program is to accelerate rooftop development within utility jurisdiction by aggregating consumers and bringing in the necessary participation from solar rooftop developers through the creation of a platform. The program also aims at educating the consumer on the benefit of solar energy while ensuring strict quality compliance of the systems being set up. To know more about the BRPL Solar City Initiative, download the information brochure by clicking here.
