Under this section, there are three basic activities. Each activity, as a separate department, deals with the nature of the currency and its specialties:
• Section of ground networks for medium and low voltage.
• General lighting section (traditional and alternative energy).
• Communications Section.
The idea behind the establishment of this division is to benefit from the general changes and conditions in the Saudi Arabia and region, and due to the difficulty of securing electricity for new projects. Therefore, the demand for new sustainable and renewable source for electricity become a must. So we decided start the Solar PV department to cover the Expected demand for projects.
Which is matching with new Vision 2030 in Saudi Arabia .
The past few years have witnessed many developments and leaps in the field of photovoltaic solar energy applications and technologies, especially the improving the scale of increasing capacity that can be generated or on the scale of low costs of setting up photovoltaic power plants.
The Division been divided into three sub-sections:
1-OFF- Grid Projects Section.
Typically, the majority of new customers entering the applications of solar energy are preferring to start with small systems and usually OFF-grid Systems whether for residential or other purposes, because they like and test the reality and the dependency of the solar systems before going the a bigger or their main projects , which generate higher electric power and of course need a larger investments.
That’s why we thought and Decided ROAA AL TATWEER to give our clients a Number of options of off-grid Predesigned systems of deferent sizes and applications according to their demands weather they are house owners mote whom want to generate some of their house electricity for their remote Rest House or farmer whom like to change their pumping systems to solar energy or any clients that’s want to install out-door or in-door lighting system or for his Store purpose . type of service .
2-Special projects section)Grid- Tied Or Off-Grid).
After the adoption of the Electricity Regulatory Authority and the dual generation of the system to generate solar power network in September 2017 and the adoption of the Saudi Electricity Company to be the service provider in Saudi Arabia, and with the introduction of the system to the actual service for public on 1/7/2018, this section expects rapid expansion and steady growth with different categories of customers( Residential – Commercials – Industrial ) especially those may achieve a maximum befit for the regulation because of their working conditions helps them comparing with other customers in the market.
Therefore, we in ROAA AL TATWEER prepared ourselves to serves these customers by this section where we can study the requests an advise them by feasibility studies commercially and technically Suggesting them the appropriate system to meet their needs , Also, we can design and implement the required system and provide the full technical support for maintenance and operation required To ensure the best performance.
3-Solar Air Conditioning Section.
In the last decay a great development have been made in the Photovoltaic power output from the Solar Modules along with the adjacent drop in cost PV Solar projects , which have leaded to open a greats chances for using the Solar PV Energy in the Field of Solar Air Conditioning which is considered one of the beigest fields the consumption of the Electricity around the world.
That what gave motive for a lot of companies working in the Air conditioning field to invest in the deployment and researches in the implementation of this advantages in the production of the Air conditions .
Where they have designed and produced many Models of Sloar Air condition units that’s work with the standard Compressor type or By the Energy Saving Air conditions that’s use the ( Inverter) technology or the DC Compressors technology that use electricity produced directly from the Solar Models.
Also we can provide different type of Solar Air conditions the match all the needs of our Valued clients weather they need air conditions that’s operate on Solar Energy completely ( Off- Grid ) type for Remote areas where no Electricity or for areas with bad or weak electricity grid with frequents drops or instability where it can operate at the time on Solar Energy and on Batteries at night.
Even for areas with good electricity grids and with the large and continuous in electricity prices all over the world , This brought a lot of clients for the Solar Air Conditioning whom are looking to reduce the value of electricity bell they paying Know.
The ( Hybrid Solar Air Conditions ) was designed for this type of clients where they can run their Air Conditions on Solar Energy at the day time where the External thermal loads is very high, and switching the supply electricity to the normal sources from the Public Grid at night where the thermal loads are much less than the day time and the cooled spaces have less eternal thermal loads due to the day time air conditions operation, which leads consequently to a big reduction in usual Electricity bell for the clients .
This department In ROAA AL TATWEER is a Project Developer and Installer, Company specializes in providing economic Energy & Engineering solutions to the residential, commercial, governmental and industrial sectors.
ROAA ALTATWEER offers a wide range of solutions that can practically cover all the needs of the client.
Our Products & Services Include:
– Energy Auditing.
– Energy Efficiency.
– Power Quality Equipment.
Due to the increasing cost in the electrical bells for the commercial sectors or due to the shortage of power supply for some remote areas , here raised the need for power generation and selling and become in the scope of our work .
Mainly our choice was to use traditional generation method, but due to high competition from the Public Electricity company or from the other companies working in the same line , we was forced to find a solution to reduce our operation cost so that we can give a better offers to our clients and to gain a bigger share of our local market and because of that our activity is described as ( De-centralized Generators ), we found that we have to be different from the other competitors is to use more efficient generating process and the best way to do that is to use the nearly new expiration and techniques off (( COGENERATION & TRIGENERATION))
1-Cogeneration ( Combined Heat & Power ) CHP
Which mean improving our generation thermal cycle efficiency by producing power and to utilize the waste heat to produce hot water for the use of the neighborhood demands and consequently improving the overall efficiency as the following :
a-Using less amount of power ( the part was used to heat water).
b-Gaining a portion of waste heat that was going as lost to heat the water for the community.
That’s why Cogeneration sometimes call as ( District Heating).
Further more efficient way to improve the thermal cycle efficiency is to use what called ( Trigeneration ).
2-TRIGENERATION ( The combined cooling, heat and power)- (CCHP):
Generally this way is utilizing more amount of the waste heat in producing :
a-Power.
b-Hot water.
c-Chilled water.
In Addition of the efficiency made in cogeneration , Trigeneration is saving more energy by the following :
1- It is known that air conditioning is the most consuming part in the power cycle so that using the waste heat to make the refrigeration or the air conditioning via the absorbtion chiller or any other mean leading to a very good saving in power consumption and to very high efficiency value.
2- Like the cogeneration Trigeneration utilize more of waste heat to generate chilled water so more efficiency improvement.
Also some times Trigeneration process in kwon as (District Cooling).
3-Hybrid Generation(Solar – Diesel) :
For a lot of applications or Locations the combined Or Hybrid generation for a solar and diesel engine generation may be the best or the most economical way combining the benefits and advantages of both in one application .
