On Grid solar power plants with grid sharing QD-Inverter technology

A PV module is the essential component of any PV system that converts sunlight directly into direct current (DC) electricity. PV modules can be wired together in series and/or parallel to deliver voltage and current in a particular system requires.

Grid interactive inverter is designed for residential, commercial and industry applications.The inverter can operate on both grid-tied and stand-alone off-grid operations. When utility power is normal, the inverter can operate as grid tie inverter which converts DC power generated by PV panels into AC power for supplying to load. When utility power is not available, the inverter can operate as backup power source to supply power from PV panels and battery.

Grid interactive system provide clean, reliable backup power in the event of a utility power failure.It can reduce energy consumption and save the utility cost, while maintaining the ability to use the renewable energy source during power outage.

Backed up by the most efficient Nano Technology Solar Modules and Quantum Direct Circuit solar inverters.

On-Grid Integration can be done as follows

  • Step-1: The solar panels convert sunlight into electric energy, which is Direct Current (DC). This current is then sent to an inverter.

  • Step-2: The inverter converts this DC to Alternating Current (AC) since households are only equipped to use AC. The grid tied inverter additionally regulates the amount and voltage of electricity fed to the household since all the power generated is mostly much more than a home needs or can handle.

  • Step-3: This ‘converted’ power supply is then used by homes through the main electricity distribution panel. Your home now has access to clean and green electricity, which makes you a contributor towards a cleaner and more sustainable environment.

  • There could be worries about how the home will receive power when the sun is not shining – that is the benefit from having the system ‘tied’ to the grid – your home receives non-stop power irrespective of the weather.

Quantum Direct Circuit Inverter

1. Generated energy from the SRTPV system is first consumed (self-consumption) by the loads of the building (lights, fans, appliances, etc.). If the SRTPV generated energy is more than the building loads consume, the surplus energy will automatically be exported to the Grid distribution network (the grid). If there is less solar energy generated than the loads of the building requirement, the shortfall energy will be drawn from the grid (energy import).

2. Who are eligible .? Industrial \ Commercial establishments with an existing electric connection

4. After installation of SRTPV system, AEE C,O&M Sub-division, EB company is the inspection authority for SRTPV systems upto 10kWp and above 10kWp, Chief Electrical Inspectorate, state governments is the inspecting authority to meet safety standards

5. The Applicant has to procure bi-directional meter from any of the approved vendors as per CEA guidelines.

6. The rooftop/terrace must have easy access.

7. The applicant should be the owner of the property or authorized person. If the property is in the name of the Company, Trust, Co-operatives / partnership firms, then authorization shall be assigned to a person for correspondence, paperwork, execution of various agreements, etc. Such person must be authorized by the management of the organization. In case of partnership firms, the authorized signatory must be one of the partners, to whom written consent has been given by the other partners.

8. If consumer is not availed subsidy, shall furnish self-certification for not availing subsidy from MNRE.

9. Application registered is not transferable.

10. Net metered energy means: The difference of meter readings of energy injected by the SRTPV system into the grid (export) and the energy drawn from the grid for use by the seller(import) recorded in the bi-directional meter.

11. The tariff for injecting surplus energy by rooftop installation will be as per the prevailing tariff determined by KERC from time to time. (At present the tariff is Rs.9.56 per unit for installations without subsidy and Rs.7.20 per unit for installations with subsidy upto 31st March 2018).

​12. n case the installed (also read proposed) capacity of the SRTPV system is higher than the sanctioned load of the consumer, which may consequently requires an up gradation in the infrastructure (service line, meter with CT (if required), transformer up gradation (if required)), the consumer will have to upgrade at his/ her/ its own cost under prevailing conditions of deposit contribution work. For further information regarding up gradation of infrastructure can be obtained from AEE(Ele,), C, O&M, sub-division Office, THE ELECTRICITY COMPANY.

13. The list of documents to be furnished along with the application are:

  • 1.Copy of the latest Electricity bill.

  • 2.Authorization letter Format-1A in case of Company/Trust/Co-operatives/ Partnership and Format -1B for Partnership firms.

  • 3.Copy of the Subsidy sanction letter from MNRE/ self-certification for not obtaining MNRE subsidy Format -1C.

15. If, the existing power supply of the consumer is of single phase and wishes to apply for three phase SRTPV system, installation shall be sanctioned from AEE, C,O&M Sub-division before applying. Otherwise the application will be rejected.

16. The Applicant shall install the meter of SRTPV system and bi-directional meter in separate meter boxes in the same proximity or at a suitable place in the premises accessible for the purpose of recording the reading.

17. Solar meter reading will be taken for statistical purpose only and not for billing.

18. Subsidy: The Applicant can avail MNRE subsidy of 30% on the capital cost of the Solar rooftop PV systems.

19. Billing and Payment:

  • 1.THE ELECTRICITY COMPANY will issue monthly electricity bill for the net metered energy on the scheduled date of meter reading.

  • 2.In case, the exported energy is more than the imported energy, THE ELECTRICITY COMPANY shall pay for the net energy exported after self-consumption as per Tariff agreed in the agreement within 30 days of issue of bills duly adjusting the fixed charges and electricity dues if any and credited to the bank account through NEFT.

  • 3.In case, the exported energy is less than the imported energy, the SRTPV consumer shall pay THE ELECTRICITY COMPANY for the net imported energy as per the prevailing retail supply tariff determined by the commission from time to time.

Grid connected solar roof top power plants with Net metering

Consumer Guidelines

Net metering is a billing mechanism that actually credits solar system owners for the electricity they add to the grid. This can be further explained with the following example: if a industrial customer has a solar energy system on their building’s rooftop, chances are it will or it should generate more electricity than the industry uses during the day. If the industry is net-metered, the electricity boxes meter will actually run backwards which in turn provides credit against what electricity is used at night.

To further explain this, net metering allows you to have only one electric meter which can spin forward or backward at the same rate. When the sun is shining, your solar system is producing electricity that can be directly used by your industry, thereby offsetting the amount of electricity being purchased from the utility company. When your PV system is producing more energy than the home needs, then the electricity is actually sold back to the utility company, causing your electric meter to spin backwards to give you a retail credit. It’s definitely not uncommon for us to receive a couple of calls a day about our customer’s excitement when they see the meter run backwards.


Sanction Load and Installed capacity:


•Installed capacity of SRTPV and small solar PV plants shall be equivalent to or less than 150% of the sanction load for both net metering and gross metering.
