Grid-tied Photovoltaic Systems

These consumer systems are neither being taxed nor licensed. No batteries need to be installed which noticeably reduces the investments.

The electricity consumed by the family is generated by the PV station on the roof.

The principle of grid-tied systems

The regulation allows up to 150kW for individuals (500kW for entities) to be installed for individual use. The role of the accumulator is played by the grid (“Electric networks of Armenia” and “ArtsakhEnergo”) the PV station is connected to. When consumption is more than generation the difference is supplied by the grid. When generation is excessive the excess is supplied to the grid which will later allow to get the same amount from the grid for free. The energy flow is monitored and fixed by the Net Metering mechanism. The wiring of the house rests intact and only the day/night meter is replaced by a bidirectional one.

Pros: the lowest investments and service needed, long life

Cons: in case of a blackout no energy could be generated
