As you know in grid-tied connection the PV system is connected to the national grid. Armenian regulation allows to sell the excess electricity to the grid at the half-tariff. Taking this into account the majority of “autonomous producers” (consumers who have switched to solar electricity to cover their needs) wants to install more powerful systems than they need, in order to make some revenue by selling electricity. But before investing (paying for a PV station) the payback period must be calculated.
Usually it's 5.5-7 years in case of PV systems generating as much electricity as you need.
If a consumer installs a more powerful PV system to make money by selling electricity he automatically makes the payback period longer which makes the investment less effective. You can calculate the optimal power using our solar calculator or by calling us.
Our specialists will help you to choose, order and install the solar system you need. Here at Shtigen we consult for free. If you aim to not save but make revenue using solar energy we inform that the new tariff for utility-scale PV stations is already known. Shtigen realizes the entire process of utility-scale PV stations construction from the design to the launch and service. Shtigen is Armenia’s leader in utility-scale PV stations market (installed 4.6MW of 10MW capacity licenced before, another 2 are in the stage of designing).
