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 […]
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
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.

The state government of Delhi had released the Delhi Solar Policy 2016, which is applicable for the four-year period 2016-2020. This policy is applicable for any solar energy generating system with a capacity of 1 kW or more. The policy focuses on promoting an investment climate that enables multiple financial models, from self-owned (CAPEX) to third-party owned (RESCO) models. The promotion of solar rooftop through a combination of generation targets, regulations, mandates, and incentives is at the heart of the new Delhi Solar Policy 2016. This policy applies to all electricity consumers and all entities who construct and operate power projects in Delhi. To achieve Delhi’s solar generation targets, the policy mandates solar installations to be completed within five years on all government-owned rooftops.

Delhi Electricity Regulatory Commission (DERC) had issued Net Metering for Renewable Energy Regulations, 2014 to promote the use of Renewable Energy Generation for self-consumption. For effective and proper implementation of these Regulations, the Commission has formulated guidelines elaborating minimum transformer level capacity that must be offered for connectivity, procedural requirements for obtaining connectivity, the technical requirement of the Renewable Energy System, the mechanism for billing, accounting adjustment (both in terms of net off as well as in financial terms) You can know more by downloading the guidelines by clicking here. The DERC has also drafted the guidelines for ‘Group Net Metering’ and ‘Virtual Net Metering’ in 2019. You can download the guidelines on Group and Virtual Net Metering by clicking here.
Renewable energy resources are naturally replenished on a human timescale Amount of feasible to utilize energy is much smaller than the energy available Renewable energy is the energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat (1). This is the most obvious and popular understanding of the renewability understanding. The concept of renewability was invented to highlight the difference between renewable energy sources and fossil fuels. Please note that fossil fuels once burned will be lost forever and burning leads to carbon dioxide emissions, not to mention methane emissions associated with extraction. The graph below compares the energy content of various renewable energy sources. The energy potential of hydropower (nascent most popular renewable energy source) is a point of reference, please note that energy generation potential of the hydropower plants is relatively small when compared to other renewables – for example, amount of solar energy available on the Earth is almost 3 000 times bigger than the hydro-energy available. Availability of the different renewable technologies, https://www.nrel.gov/gis/re-potential.html The abundance of the energy source does not mean that the energy would be effectively utilized. For example, geologists were well aware of the existence of gas in shale rocks, but the extraction was technically impossible. Due to technological development, previously unreachable energy sources (shale gas) appeared to be one of the cheapest fuels, revolutionalizing energy markets and setting new rules for international politics. There are factors determining the […]
