How On grid Solar System Works?
When sunlight hits the solar photovoltaic (PV) panels, electricity (or 'solar energy') is produced.
The electricity then runs from the solar panels through an inverter.
The inverter turns the power from direct current (DC) into alternating current (AC), which you can then use for electronic appliances in your home.
If the appliances in your home are turned on while solar power is being produced, the power runs through the switch board and the solar power is sent to your appliances.
If electrical appliances are switched off, or if excess solar power is being produced, the power gets sent to the grid which is measured by the Bi-Directional meter box. Your electricity retailer applies credits in exchange for the energy you produce. During the night, when your solar power system is not producing energy, you will draw power from the grid, which you can pay for with credits earned from exporting solar power during the day.
Solar Rooftop System provides following technical benefits:
- Utilization of available vacant roof space;
- Low gestation period;
- Lower transmission and distribution losses;
- Improvement in the tail-end grid voltages and reduction of system congestion;
- Loss mitigation by utilization of distribution network as a source of storage through net metering;
- Long term energy and ecological security by reduction in carbon emission;
- Abatement of about 60 million tones of CO per year over its life cycle;
- Better Management of daytime peak loads by DISCOM/ utility;
- Meeting of the renewable purchase obligations (RPOs) of obligated entities which are targeted at 8% of electricity consumption;
- Minimal technical losses as power consumption and generation are colocated

Frequently Asked Questions for Grid Connected Solar Rooftop Systems:
1. What is a Solar Rooftop System?
Ans. 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) Solar Rooftop System with storage facility using battery, and (ii) Grid Connected Solar Rooftop System.
2. What is a Grid Connected Solar Rooftop System?
Ans.In grid connected rooftop or small SPV system, the DC power generated from SPV panel is converted to AC power using power conditioning unit and is fed to the grid either of 33 kV/11 kV three phase lines or of 440/220 Volt three/single phase line depending on the capacity of the system installed at institution/commercial establishment or residential complex and the regulatory framework specified for respective States.
These systems generate power during the day time which is utilized fully by powering captive loads and feed excess power to the grid as 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.
3. Where such plants can be installed?
Ans. Such rooftop systems can be installed at the roofs of residential and commercial complex, housing societies, community centers, government organizations, private institutions etc.
4. What is the average cost of grid connected rooftop solar systems?
Ans. The average cost of grid connected rooftop solar systems is about Rs. 65 per watt per capacity.
5. What is the size of grid connected rooftop solar system?
Ans. The rooftop solar systems from 1 kWp upto 500 kWp or in combination can be set up on the roofs.
6. How much roof area is required to set up the grid connected rooftop solar system?
Ans. About 10sq.m area is required to set up 1 kWp grid connected rooftop solar system.
7. In case of grid failure, is there any chance for shocks to the person who is repairing?
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’.
8. Net metering
Ans. The grid connected rooftop system can work on net metering basis wherein the beneficiary pays to the utility on net meter reading basis only. Alternatively two meters can also be installed to major the export and import of power separately. The mechanism based on gross metering at mutually agreed tariff can also be adopted.
Ans. In feed-in-tariff the Government offers a tariff for purchase of the solar power generated from such plants.
10. Among net metering and feed-in-tariff what is preferred?
Ans. Net metering mechanism is more popular among States.
11. How many States have policies to promote grid-connected rooftop solar systems?
Ans. So far, 13 States/UTs namely Andhra Pradesh, Chhattisgarh, Delhi, Gujarat, Haryana, Karnataka, Kerala, Punjab, Rajasthan, Tamil Nadu, Uttarakhand, Uttar Pradesh and West Bengal have notified policies that include promotion of grid connected rooftop solar systems with net metering. Regulation from the State Electricity Regulatory Commission is also required to allow net metering/ feed-in-tariff.
12. How many States Regulators have notified orders to promote grid-connected rooftop solar systems?
Ans. 20 State/UT Regulators from Andhra Pradesh, Chhattisgarh, Delhi, Gujarat, Haryana, Karnataka, Kerala, Odisha, Punjab, Rajasthan, Tamil Nadu, Uttar Pradesh, Uttarakhand and West Bengal, Andaman & Nicobar, Chandigarh, Dadra & Nagar Haveli, Daman & Diu, Lakshadweep, Pondicherry and Goa have so far issued these regulations for net-metering/gross metering.
13. What are the grid connectivity levels for such systems?
Ans. The Projects under these guidelines fall within two broad categories i.e.(a) the projects connected to HT voltage at distribution network (i.e. below 33 kV) (b) the projects connected to LT voltage i.e. 400/415/440 volts (3-phase) as the case may be or 230 volts (1-phase). Accordingly, the projects may be under the following two categories.
Category 1: Projects connected at HT level (below33kV) of distribution network
The Projects with proposed installed capacity of minimum 50 kW and upto 500 kW and connected at below 33kV shall fall with in this category. The projects will have to follow appropriate technical connectivity standards in this regard.
Category 2: Projects connected at LT level (400 Volts-3 phase or 230 Volts-1 phase)
The Projects with proposed installed capacity of less than100kW and connected of the grid at LT level (400/ 415/ 440 volts for 3-phase or 230V for1-phase) shall fall within this category.
