Solar Heating and Cooling in Armenia
Armenia possesses enough favorable opportunities for solar energy development.
There are 2500 sunny hours per year and the average annual solar radiation on
a horizontal surface is 1720 kWh/m2. In Europe, this value is 1000 kWh/m2.
Water Heaters produced by a New Joint Venture Manufacturals
During the implementation of a two-year program (2000-2001), ARMNEDSUN, sponsored
by the Government of the Netherlands, 15 demonstration solar water heaters (SWH)
were installed without charge on the territory of Armenia. In addition, a joint
venture, SunEnergy LLC, was established between ZEN (The Netherlands) and Technocom
LLC (Armenia) to manufacture solar collectors in Armenia, with a budget of 600.000
Another 15 SWH were installed at half price. A standard SWH produces hot water
for bathing and washes; it includes a solar collector with area of 2.75 m2 and
a water tank of 140 l. The current price of this system is 1150 USD.
The solar collectors of this company are currently installed on the rooftops
of 7 homes in the Vahagni residential community, of the hotel Terdjyan
(22m2), in Tsapatakh (30m2) near Lake Sevan, in the Blue Sevan holiday
resort (see photo 2), etc, for a total areas of 300m2. The standard system
up to 65% of the energy demand for hot water for a 5-member family. The
pay-back period is about 5 years. 1 m2 of solar collector saves around
0.49 t c.f./year
and reduces emissions of GHGs by 0.8 t CO2/year.
In 1999-2002, a solar-driven desiccant cooling demonstration system was
installed in the building of the American University of Armenia. The solar
are used to heat up auditorium space and produce the hot water supply during
the cold period. They also restore working substance, :which absorbs humidity
and make the incoming air dry) during the warm period. In total, 32 flat
water heaters are used. The surface of each collector is 2m2. The total
surface of the solar system is 64 m2. The equal electrical power of the
kW. The system allows reducing consumption of electric energy by as much
as 80%. The system can save 31.2 t c.f./year and can reduce GHG emission
t CO2 /year.
The project was part of the INCO Copernicus program, with funding from the Commission
of European Communities, DG XVII (budget 400 000 EUR). The participants of the
project were INETI (Portugal), Fhg-ISE (Germany), Intersolarcenter (Russia),
AUA, and Contact-A Ltd (Armenia). 75 % of the total sum is paid by EC, 25% by
participants from Germany and Portugal.
