Solar Power Has Become An Important Part Of India's Economy To Increase Energy Security, Address Environmental Concerns And Lead The Massive Markets For Renewable Energy The generation of solar power has tremendously increased in the last few years owing to the government’s favorable initiatives and innovative manufacturing technology. Total installed renewable energy capacity (Solar+Wind+Hydro) in India touched 114.43 GW (around 33 percent of the total energy capacity of the country). The Indian government is planning to expand its solar plans, targeting US$100 billion in investment and 100 GW of solar capacity by 2022. The country's solar installed capacity reached 29.55 GW as of 30 June 2019. India has the lowest capital cost per MW globally to install the solar power plants. The Indian government had an initial target of 20 GW capacity for 2022, which was achieved four years ahead of schedule. Here are the following reasons why investing in solar power franchise can provide you with huge profits.

In a solar rooftop system, the solar panels are installed in the roof of any residential, commercial, institutional and industrial buildings. This can be of two types (i) Off Grid System - Solar Rooftop System with storage facility using battery. (ii) On Grid/Grid Connected Solar Rooftop System.
Ans: In Grid connected Solar Rooftop PV system the DC power generated from SPV panel is converted to AC power using power conditioning unit .Generated Power by this system during the day time is utilized fully for powering captive loads and excess power is fed to the Grid. Grid connected Solar Rooftop system is operational so long as grid is available. In case, where solar power is not sufficient due to cloud cover etc., the captive loads are served by drawing power from the grid.
Ans: i) Electricity generation at the consumption center and hence Savings in transmission and distribution losses ii) No requirement of additional land iii) Improvement of tail-end grid voltages and reduction in system congestion with higher self-consumption of solar electricity iv) Local employment generation.
Ans: About 10sq.m south facing shadow free area is required to set up 1 kWp grid connected rooftop solar system.
Ans: Subsidy/Support is available from Central Government through MNRE: The subsidy available on Installation of Grid connected Solar Rooftop Power Plants is 20% of benchmark cost. i.e. Rs. 11,000/- per kW (benchmark cost is Rs. 55,000/- per kW) or project cost whichever is minimum
Ans: Government Institutions including Public Sector Undertaking (PSU) shall not be eligible for subsidy; instead they will be given achievement linked incentives/awards. (refer MNRE guidelines - May 2019).
Ans: Generally 1 kW SPV generate 4-5 kWh / units per day. It depends upon the system as well as solar radiations.
Ans: This can be calculated by dividing the available area by each panel area and multiplying it by panel’s rated output. For estimate purpose, 70% – 90% of rooftop area can be used for panel’s installation. The output per panel and hence system output depends on panel efficiency and the solar radiation at the site. These two factors define CUF (Capacity Utility Factor) for solar system for a particular location. For India typically 19% CUF is taken for estimation. The annual number of units generated by solar system can be calculated as: Units Generated Annually (in Kwh) = System Size in Kw * CUF * 365 * 24 As a thumb rule, 1 Kw capacity solar system generates 1600 – 1700 Kwh of electricity per year. The CUF varies with the geographical location of the installation site. Following table summarizes indicative CUFs at different cities in India.
Ans: The benchmark cost of MNRE, GoI is Rs. 75000/- per kW. For installation of grid connected rooftop solar power plant in Maharashtra State the benchmark cost is Rs. 61000/- per kW which is arrived from expression of interest (EoI) floated by MEDA as per the guidelines of MNRE, GoI.
Ans: It is required that Rooftop Solar Power Plant System should be located in the premises of the consumer.” Premises” means rooftops or /and elevated areas on the land ,building or infrastructure or part or combination thereof in respect of which a separate meter or metering arrangements have been made by the utility for supply of electricity
Ans: “Net Meter” means an energy meter as defined in the Electricity Supply Code which is also capable of recording both the import and export of electricity, or a pair of energy meters, one for recording the import and the other for recording the export of electricity.
Ans: “Net Metering Arrangement” means an arrangement under which a Roof-top Solar PV System with Net Meter installed at an Eligible Consumer’s premises delivers surplus electricity, if any, to the Distribution Licensee after setting off the quantum of electricity supplied by such Licensee during the applicable Billing Period.
Ans: “Net Metering Connection Agreement” means an agreement entered into by a Distribution Licensee and an Eligible Consumer for executing a Net Metering arrangement.
Ans: In case of electricity injected in the Grid exceeds the electricity consumed by the consumer in the billing period ( Monthly electricity bill ) ,such excess injected electricity shall be carried forward to the next billing period as electricity credit and may be utilised to net electricity injected or consumed in future billing periods but within the settlement period (-from 1st of April in an English calendar year and ending with the 31st of the March of next year ) .At the end of settlement period any electricity credits ,which remain unadjusted ,shall be paid at average cost of power purchase as approval by MERC for that year.
Ans: Yes. The net meter (Bidirectional meter) is to be installed by the distribution company.
Ans: In case the grid fails, the solar power has to be fully utilized or stopped immediately feeding to the grid so as to safe-guard any grid person/technician from getting shock (electrocuted) while working on the grid for maintenance etc. This feature is termed as ‘Islanding Protection’.
Ans: It is a contract of maintenance with installer having period of 5 year.
Ans: It is assume that the lifetime of SPV power plant is 25 years
