More information
As previously noted, the yearly thermal energy required for domestic hot water usage of the facility is around 258,693.23 kWh. This energy is currently provided by a Diesel boiler system composed of 4 boilers heating 4 water tanks of total capacity 5,250 Liters. The boiler system is assumed to have constant Diesel consumption and constant energy production for thermal energy for water heating all around the year because of the regular occupancy of the facility.
The proposed solar water heating system consists of 255 square meters of Solar Pergola area that are expected to generate around 256,019.09 kWh of thermal energy yearly.
The energy coverage of the solar water heating system covers approximately 83% of the yearly energy demand for hot water consumption.

Reasons for participating in the competition(s)
Maison Notre Dame Du Mont in Fatqa is inhabited by 151 people on average all year long. For domestic hot water consumption, a central hot water system is currently used, consisting of 5,250 Liters storage heated by 4 Diesel boilers, serving domestic hot water use for both the Nursing Home and the Hotel. This project is the integration of 255 Square Meters Open
Type Vacuum Tubes Solar Pergola.
This system transforms solar
energy into thermal energy for use in various applications such as Pool
Heating, Water Heating, Space Heating, Process Heat and Solar Air Conditioning
while preserving an aesthetic image. The Pergola Solar System being the only
solar system with absorbers installed at 0 degree of inclination and having a
system structure that can be constructed from a wide variety of materials makes
the Pergola Solar System a unique design for Solar Water Heaters.
The diversity of materials and
colors present an added value to the system, as the structure could be made
from wood, aluminum, colored steel, stainless steel… to suit different
architectural needs.
The Pergola Solar System was
patented in 2009 (Patent No. 8589 - Ministry of Economy and Trade – 2009). This keeps the Pergola
Solar System away from the competition whirlpool.
The Pergola
Solar System is a pioneering product outweighing all standard type solar
systems available in the market. Its uniqueness increases its commercial value.
The Pergola solar system can
be easily expanded or upgraded on
demand.
This system was implemented in
parallel with the existing boiler system and to be connected to new and
existing storage tanks.
The total cost of the project is 159,999.00 USD.
The expected yearly savings of the
system are around 32,402.42 USD and the payback period
is 5 years.
The current yearly expenses on
Diesel for thermal energy generation are approximately32,740.86 USD,
equivalent to a yearly consumption of 36,378.74 Liters of
Diesel. Hence, the current thermal energy required is 258,693.23 kWh.
The installed solar water
heating system is expected to generate yearly 256,019.09 kWhof
thermal energy, hence covering 83% of the yearly energy demand
for hot water consumption, and reducing CO2 emissions by 94,687.06 kg yearly.
The roof of the facility is suitable
for such an installation and the construction can accommodate all required
items for implementation.
During its lifetime of 28
years, the system will cost the user 182,399.00 USD (including
maintenance and consumables) and will generate 6,279,654.59kWh of
thermal energy. The cost of thermal energy from the installed system is 0.03
USD/kWh.
Over the years, the system would have
cost 182,399.00 USD and would have saved794,768.78 USD (taking
into consideration the degradation factor). Hence, according to the current
Diesel price, the system would benefit the user with 612,369.18USD during
its lifetime.
Presentation of the Installed Project
The installed system for
installation is 255 Square Meters Open Type Vacuum Tubes Solar Pergola that is
to be implemented in parallel with existing boilers and connected to both
existing and new hot water storage tanks.
Our objective was to separate
the two main parts of the project (Hotel and Nursing) by the mean of hot water
production and to reduce fuel consumption by introducing solar energy.
Existing Status: 4 boilers around 230 KW are serving both nursing
and hotel facility with common heating supply system.
Modification on Existing system: additional boiler with a capacity
of 400 Kw should be installed, and one the exiting boilers shall be connected
to the newly installed boiler and separated from the exiting 3 other boilers.
This new configuration shall allow independent heating production for nursing
home from the hotel.
Concerning Nursing Home, separate boilers shall be installed in
the technical room as discussed above, and a common solar system made up of 255
square meters were installed on roof. These panels are currently heating a new
hot water storage tank of 1500L capacity in order to preheat the cold water
entering the main solar and boiler heated hot water storage tank of 1500L
capacity also.
The existing boilers shall be dedicated to the hotel and the same
common solar system was installed on roof. These panels are currently heating
an existing hot water storage tank of 1500L capacity in basement technical room
in order to preheat the cold water entering the double coil new hot water
storage tank of 1500L capacity serving Hotel’s first and second floors. As for
the kitchen and laundry, a new double coil hot water storage tank of 1000L
capacity was installed. These solar panels are heating
also the existing hot water
storage tank of 1500L capacity in hotel’s roof technical room in order to
preheat the cold water entering a new added double coil hot water storage tank
of 1500L serving Hotels third and fourth floors.
During sunny periods of year, the installed system is expected to
cover all the hot water consumption of the facility, hence skipping the use of
the boilers for water heating during this season (April to September). In
mid-seasons between summer and winter, the system is expected to cover around
50% of the hot water consumption, hence reducing considerably the current fuel
consumption for heating water in these seasons. During winter, the system is
expected to cover around 40% of the hot water consumption, therefore, a
reduction on the fuel expenses will also come about in this season.
This system was implemented
to make use of natural resources to reduce fuel consumption for water heating.
Moreover, energy meters were installed in order to measure the energy ( in kWh
) and the flow ( in Liters per Second ) of the hot water in order to keep track
of the hot water consumption. Data will then be available for further study
whenever more actions are needed to analyze the energy consumption for domestic
hot water provision.
The main components of this system are the following:
255 m² Open Type Vacuum Tubes Solar
Pergola
4 Differential Temperature Controllers
2 sets of Circulating Pumps
1 Open Type Expansion Tank
4 Three-Way Valve
Make-Up Water System
7 Energy Meters
4 Flow Meters (water meters and fuel
meters)
4 New Hot Water Storage Tanks
Galvanized Steel Pipes
UPS Battery System
Boiler 400Kw
The system was implemented according
to highest standards of quality and safety.
