Frequently Asked Questions

Technically possible, but inefficiently so. During the winter, solar energy production is at its lowest, and consumption is at its highest. The amount of investment required to install the required capacity is, in many cases, equal to the cost of 15 years of gas heating. That is, if the same amount is simply invested in the bank as a deposit, the interest income will exceed the gas savings.

Electricity generation in photovoltaic stations depends on the degree of illumination. Almost no electricity is generated during fog. And at night, due to the lack of sunlight, no electricity is generated at all. The operation of solar water heaters also depends on the level of illumination. The water will hardly heat up in foggy weather. Depending on the degree of cloudiness, the water in the solar water heater will heat up to different temperatures. In winter, in direct sunlight, the water temperature will reach the level required for domestic use, even if it is very cold outside. In summer the water temperature reaches boiling point.

No, not required. The main change is limited to the change of the meter. The standard meter is replaced by a two-way meter.

Yes, it is possible. If you are sure that you will need to increase the number of panels some time after installation, installing one powerful inverter at first will be more profitable than installing a second small inverter.

It is not desirable to clean the solar panels and flasks from the snow. It is not advisable in snowy weather, as there is no sun, and the billboards will be covered with snow again. In hot weather, the snow will melt as the panels warm up. And if the boards or flasks are dirty, they can be cleaned with distilled water or a soft microfiber cloth. Do not clean the panels in hot weather when they are hot. As a rule, the need to clean the solar panels occurs at most once a year.

A two-phase single-phase meter costs 11,000 drams, a three-phase one 55,000 drams. It can be purchased from any licensed manufacturer. After the installation of this meter, ENA CJSC reimburses its cost one year after the date of installation as an advance payment for electricity.

The reduction in electricity production from photovoltaic panels depends not only on the weather conditions but also on the slope of the panels. With an optimal slope of 38 degrees, electricity production is reduced by 2 times compared to December (the rainiest month) and July (the rainiest month). In the case of horizontal installation, this figure reaches up to 3.3 times.

During the summer, calculate the number of occupants in the house (approximately 50 liters per person) and gas consumption. If the number of residents is up to 4, and the gas consumption is up to 8000 AMD, then a 200-liter water heater will be optimal. And if there are five residents, the gas consumption is up to 10,000 drams or 250 liters. Gas consumption for 6-7 more residents is approximately 11000 AMD, followed by 300 l.

Yes, it is possible. We recommend installing non-pressurized solar water heaters on the three floors above the building to avoid high heat loss in the pipes. Balcony pressure models can be installed on any floor of an apartment building. Solar power plants can be installed on the roof of the building for residents of any floor. It should be noted that when installing on the roof of an apartment building, the availability of the roof the consent of the co-owners is required.

The temperature of the water in the solar water heater can reach up to boiling point Celsius. After that, the water starts to evaporate and comes out in the form of steam from the hole provided for it above the water heater. Therefore, there is no need to worry about seeing steam if you do not use the water heater for a long time or do not charge the water heater.

Photovoltaic panels can vary in size and material. Polycrystalline panels are used in standard cases, as they have the best combination of price and quality. If there are some features within the project, then the optimal panel type is selected accordingly. For example, if installation space is limited, monocrystalline panels with higher productivity are often used.

On average, it occupies 6-7 m2. In the case of large stations, there is also a certain distance between the rows of panels, which should be taken into account when choosing an area.

Yes, the inverter is sold separately

We do not sell cables

Who to contact to purchase and install a charging station? There are charging stations in Yerevan Mall, Dalma Garden Mall, on the Yerevan-Sevan highway, in Goris, Amberd, Sisian, and Tsaghkadzor. You can find more information about them on our website or go to the following link: https://bit.ly/3P31h7A

Installing solar panels on the roofs of multi-story buildings is only appropriate for residents living on the top floors. At the same time, the signature of 70 percent of the people living in the given building will be necessary for the purpose of the agreement
