10. Solar Heating
Basics:
 Hot water always rises to the top: convection;
 No heat exchange occurs within vacuum.

11. Vacuum SWH Features
 Payback starts from 3 years
 Works under frost conditions of -30 Co, not damaged even by direct
hit of 3cm of hail
 Individual installation, lower operational costs
 Compatible with previously installed systems
 Thermal Energy for heating systems is possible, but not economically
viable, unless there is a increase in summer demand (e.g. swimming
pool)
 5 year product warranty, 20 year product life span
 Leasing: 10.5% in AMD, 10-20% prepayment, 5 years maturity
 1 year free system service

13. Solar Power
Basics:
 Under sunlight the semiconductor generates electricity
 Electricity is transformed to the grid parameter via inverter
 Net metering allows to use the grid as a virtual battery by
supplying excess electricity to the grid and receiving it back
when necessary. Excess electricity as of December 31 is
purchased at 50% of the retail electricity tariff

14. PV Features
• Payback starting from 7 years, in case of Net metering;
• Full energy independence in case of using an air conditioner for home
heating (no natural gas cost) during Net metering;
• Installation does not require any changes to the existing grid,
installation of а special meter needed only;
• Occupied area: 7-8 sq.m for 1kWh of capacity;
• Individual installation, low operational costs;
• 25-year power warranty and 10-year inverter warranty;
• Possibility of online supervision and optimization of system
performance;
• Leasing: annual 10.5% in AMD, 10-20% prepayment, 7 years;
• 1 year free post purchase service.
