In grid connected rooftop or small SPV system, the DC power generated from SPV panel is converted to AC power using Inverter and is fed to the grid either of 440/220 Volt three/ single phase line installed at residential, institution/commercial establishment. These systems generate power during the day time which is utilized 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 balance power from the grid.

Solar PV Modules/Solar Panels – The Solar PV modules/Solar Panels convert solar energy to electrical energy. They are available in different technologies such as Mono Crystalline, Poly Crystalline, thin film, CIGS, CdTe, HIT, etc. Poly Crystalline Solar PV panels are most common in use on roof tops. Inverter – Inverter converts DC output of Solar PV panels into AC power. Mounting structure – The mounting structure is the support structure that holds the Solar PV panels Balance of System – These consist of cables, switchboards, junction boxes, meters, structures, earthing system ,circuit breaker, fuses etc.

Rooftop solar PV systems can be installed on any type of roof having sufficient load bearing capacity.

Saving on electricity bill by the consumer. Utilization of available vacant roof space, no additional land required. Low gestation period. No additional requirement of transmission and distribution (T&D) lines. Reduces T&D losses as power consumption and generation are collocated. Improvement in the tail-end grid voltages and reduction of system congestion. Long term energy and ecological security by reduction in carbon emission. Better management of daytime peak loads by DISCOM/ utility. Meeting of the Renewable Purchase Obligations (RPOs) of obligated entities

The grid connected rooftop system can work on net metering basis wherein the beneficiary pays to the utility on net meter reading i.e. the difference between the import and the export energy, if the imported energy is more than the exported energy. If the exported energy is more than the imported energy the utility will pay to the beneficiary for the net energy exported. This concept is applicable to the solar applications registered before 25.03.2019. Thereafter, net feed-in method of billing is applicable.

Under net feed-in scheme for the applications registered on or after 25.03.2019, the surplus/excess energy generated that is unutilized and that flows to the grid at the end of the billing period will be calculated at a tariff fixed by the Hon’ble Commission and credited to the consumer’s account. The energy that is imported from the grid by the consumer will be calculated at the appropriate retail tariff and the monetary value of imported energy debited from the available credit on account of exported energy in the respective billing period. Any credit available in the account of the consumer after debiting value of imported energy will be carried over to the next billing period for adjustments against subsequent billing. If the amount to be debited is higher than the credit in a billing period, the consumer will have to pay the difference in charges..

Depending on the sanctioned demand of the existing service, load requirement of the beneficiary and availability of shadow free rooftop area, the beneficiary may decide the capacity upto 150 kW under LT service.

The system is easy to be dismantled and reassembled elsewhere. So, it can be shifted to new residence.

Feasibility process will be waived off for 3KW of Solar applied load.More than 3 KW feasibility process will be done by TANGEDCO.

On installation of the PV plants by the vendor, the vendor/consumer will send the readiness report to TANGEDCO. After completing the inspection by AEE/O&M for installations of capacity of 10 KW and by CEIG for installations of capacity of above 10 KW, on receipt of inspection report, bi-directional meter will be installed by TANGEDCO for providing grid connectivity.

The RTS under any framework like net or gross metering can be installed by the electricity consumer. So, if applicant have electricity connection in his/her name and he/she pay regularly the electricity bill in his/her own name and also have the permission of use the roof for solar rooftop installation from the owner, he/she can install the RTS.

A 1 kW rooftop system generally requires 10 sq. meters of shadow-free area. Actual sizing, however, depends on local factors of solar radiation and weather conditions, efficiency of solar module, shape of the roof etc.

• Cheaper and environment friendly electricity.
• Excess energy can be fed into the grid with tariff as determined by the State Electricity Regulatory Commissions .
• Electricity generation occurs at consumption center thus, saving transmission and distribution losses
• Lower payback period.
• 25 years guaranteed lifespan of the solar photovoltaic panels
• Highly modular
• Subsidy is available from the Central Government for domestic category (residential) of LT consumers.
• Quick installation

Grid Connected RTS System cannot generate electricity during the night. In the absence of generation during night/monsoon, power supply will be fed from the grid.

The Grid Connected Rooftop Solar (RTS) system installed on a roof will generate an average of 4 to 5 units of electricity per kWh per day.

Not required.

All kind of loads, including inductive, capacitive and lighting load in category of LT services except hut and agriculture can be connected with Rooftop Solar (RTS) system.

A Grid Connected Rooftop Solar (RTS) power plant has a lifespan of 25 years.

• For the applications registered before 25.03.2019 , under Solar Net Meter Category based on Tamil Nadu Solar Policy 2012 the following billing procedure is adopted: In any billing cycle if the energy imported by the consumer is more than the energy exported to the grid over and above his self consumption, then the import kwh and export kwh are adjusted and the bill will be raised for payment by the Consumer as per existing norms and the applicable service connections tariff. In any billing cycle, if the energy exported exceeds energy imported, the surplus of export Kwh over import Kwh shall be carried over to the next billing cycle for adjustment against the import Kwh of that billing cycle.
• For the applications registered on or after 25.03.2019 , under Solar Netfeed-in Category based on Tamil Nadu Solar Energy Policy 2019 the following billing procedure is adopted: Energy settlement will be done on monthly basis. The electricity generated by the RTS will be utilised for the self consumption by the consumer. The excess unutilized energy flowing into the grid and recorded in the export register of the meter will be credited into the consumers account at a tariff fixed by the Regulatory Commission. The energy that is imported from grid by the consumer will be calculated at the appropriate retail tariff and the monitory value of imported energy debited from the available credit on account of exported energy in the respective billing period. Any credit available in the account of the consumer after debiting the value of imported energy will be carried out to the next billing period. If the amount to be debited is higher than the credit in a billing period, the consumer will have to pay the difference in charges. At the end of the settlement period monitory value of surplus generation, if any will be settled by TANGEDCO.

For installed PV systems of capacity above 10 KW, CEIG approval is compulsory.

Consumer has to comply with CEA standards and relevant safety standard as followed by CEIG.
