Some discussions regarding Solar PV and its general inquiries – Part 1
Ever wondered if you’re getting the right system for your project? After all, there is not a “one size fits all” system. Here in Saudi Arabia, where electricity is inexpensive even after the recent changes to electric tariffs, makes it a challenge for most to differentiate the line between actually saving and hurting your return of investment, requiring more thorough study of current requirements and looking into the future due to the state of change the country is going through. It’s not as simple as filling your roof with photovoltaic panel equals savings, generating electricity is not the only solution. There several factors and solutions applicable here in Saudi Arabia to consider to achieve optimum feasibility in your plans:
Your Consumption.
How soon do you want your return of investment.
Quality, lifetime of the product, this is important to not just have a return of investment but to gain from your investment.
Is it the right solution for your requirements. Is it really what you need to prioritize in you journey towards Net-Zero.
Contact EGPHIL Solar Solutions to discuss all these matters and find the right solutions for you.
LED luminaire manufacturer are a plenty. We are often asked how we chose to partner with GigaTera and not any other brand. Simply saying…… they have the better products.
LED lamps have been known to be fragile in performance if exposed to unfavorable conditions. That seems to be everywhere in and outdoor and external setting of Saudi Arabia. we searched for a product that is protected against extreme conditions yet flexible in design and function that it can meet the major lighting requirements in the sector.
Efficiency in LED refers to getting the most light from least power consumption. This is easily possible by overpowering your LED chips, but this is sure to reduce its lifetime. The best efficiency refers to highest light output per watt acheived while maintaining least stress on the chips to maximize its lifetime. GigaTera LED lamps have high lumen per watt using medium power LED chip output, that is Efficiency.
GigaTera lamps also use reflectors instead of optics. Optics are causes of light loss. they are also causes of lamp failure as we have observed optics degrading and even burn of due to chip heat. reflectors can be designed to meet light distribution angle with efficiency. They can also work together with optics to provide focal power needed in high lighting requirements such as sports lighting. This avoid light pollution. Reflectors also allow indirect light distribution. So you are never looking straight on to a chip which causes glare issue. That is Comfort.
Contact EGPHIL Solar Solutions to help you with you LED lighting need. You will not need to search anywhere else.
Get everyone on board by including green focus in your company’s image. Psychology shows that if you label something a certain way, it becomes a self-fulfilling prophecy. If you want to have a green set, the first thing you’re going to have to do is take ownership of that fact. By announcing your operation is going “green,” you will inspire your employees to get behind it.
Hire or designate a team to focus on achieving your goals as a company who’s going green. Most company have Environmental specialist or department that handle these. This is a crucial step to actually get the wheels moving. Your current employees will be busy on other matters, you’ll need a person whose sole focus is to get your company closer to sustainability, guide everyone and look into solutions that are applicable and will benefit your company, a plane won’t fly on its own without its crew.
Create some yearly goals. Setting out an annual plan with milestone evaluations will allow us to monitor the changes and further inspire workers and management towards the goal.
Go natural. Improve ergonomics with nature. Maximize Natural Light, improve facility ventilation, adjust internal policies to meet natural occurrence.
Go natural some more. Use reusable bags, containers, and utensils. Avoid disposables.
Adjust habits based on availability and eliminate the culture of waste.
Nurture plants in your facility. Who doesn’t like greenery in their surrounding?
Limit waste. Reuse. Recycle. Be resourceful. Everything serves multiple purpose before it becomes trash. Be creative to maximize the possibility.
And lastly, spread and share. Aside from being a green institution yourself, getting people into the movement towards sustainable and greener future is the next best thing.

Photovoltaic Rooftop Market Rooftop solar photovoltaic (PV) systems are becoming a preferred source of energy worldwide. Declining PV equipment costs are reducing end-user kWh cost equivalents to levels below the cost of utility-generated energy in many countries. The future of the global rooftop solar PV market appears to be very bright and promising.
A recent report from Transparency Market Research titled “ Rooftop Solar PV Market – Global Industry Analysis, Size, Share, Growth Trends, and Forecast 2015 – 2023” projects that the global rooftop PV market will grow to $4.58 billion by 2023. North America currently accounts for the largest share of the global rooftop PV market, but growth rates in the Asia Pacific Region are predicted to outpace all other regions to represent $1.09 billion of the global rooftop market by 2023. India and China are expected to be the main drivers of this growth.
PV solution providers are scaling-up to accommodate rapid market growth, but declining equipment costs decrease PV solution provider per-project revenue and profit. Increased price competition between solution providers exacerbates this problem, because offering a lower price (with lower-margin) is often needed to win the deal. Incorporating TDDs into a PV system design reduces this negative impact on profitability as discussed in the following sections of this article.
Tubular Daylight Devices Tubular Daylighting Devices, or TDDs, are high-performance optical lighting solutions that bring daylight into buildings, and can be an especially-effective solution for interior areas where traditional skylights and windows cannot reach. TDDs are sometimes called “tubular skylights,” “light tubes,” “sun pipes,” and even “light tunnels,” TDD technology is composed of three zones that capture, transfer, and deliver daylight. The components in each zone incorporate designs that consistently deliver the maximum amount of “good” visible light while excluding damaging UV light as well as excluding excess heat from infrared light. TDDs are designed to deliver stable light levels throughout the day and throughout the seasons to provide a consistent daytime lighting environment to building occupants. TDDs are sealed, require no power to operate, do not have moving parts, and do not require maintenance.
TDD technology can direct light through long tubing runs that includes multiple angle bends. This allows the exterior light-collecting domes to be clustered into groups that leave more rooftop space available for PV panels. This property can enhance the value of a PV system implementation as discussed in the following sections of this article.
Roof Space Limitations with Traditional Skylights Available rooftop space is often inadequate to install a PV system that meets all commercial end-user energy need. Contributing factors to this limitation are that most building codes require commercial rooftops to include skylights and that building codes also require a 4-foot setback from each skylight as well as a 6-foot-wide access path to each skylight. This constraint dramatically reduces available space for PV modules. The photo above is a commercial rooftop installation with traditional skylights that demonstrates this constraint.
Traditional skylights are positioned directly over the interior areas they illuminate, so their layout is generally dispersed uniformly over the roof area. This positional constraint of traditional skylights makes it necessary to fragment the PV panel layout on the roof. The green area in the example schematic layout to the right demonstrates this limitation. The green area is the maximum space available for a PV system with a typical traditional skylight layout. About 67% of the roof area is available for PV in this example.
Utilizing TDDs to Make More Roof Space for PV Panels TDD light-collecting domes can be grouped-together as shown in the photo below. The second photo below demonstrates how TDDs can be configured to direct light through reflective tubing to where it is needed inside the building. Unlike traditional skylights, TDDs do not need to be positioned directly over the interior area they illuminate. The rooftop domes of TDDs can be concentrated in smaller roof areas to make more space for PV panels.
Reducing the Installed Cost/Watt of PV Roofs with traditional skylights generally require asymmetrical PV layouts and such asymmetrical designs tend to cost more due to the additional racking, wire and labor required. Large, symmetrical PV arrays tend to have a lower total cost per installed watt for this reason. Incorporating TDDs into a PV design enables the design of more-symmetrical PV panel layouts which reduces system cost. Additional cost savings can increase the economic benefit to both the end-user as well as profit margin to the system provider.
Basis for TDD Operational Savings TDDs save electric lighting expense in a straightforward way. As daylight levels increase in the morning, interior electric lights are dimmed or switched-off, typically with an automation system. As daylight levels decrease in the evening, the lights are brightened or switched-on.
Electric lighting wastes around 70% of input kWh as heat generated inside the building. HVAC equipment in needed to remove this heat energy added to the building. HVAC equipment consumes energy to remove this waste heat from a building interior. Deploying a TDD system enables the end-user to turn-off electric lighting systems to reduce waste heat added to building interiors and reduce the corresponding HVAC energy consumption to remove the waste heat.
Electric lights have a finite operational hour lifetime. Daylighting with TDDs reduces the number of hours electric lights are used each day. This reduced electric light usage adds-up and extends electric light calendar life. With a longer calendar life, costly lighting equipment replacements can be avoided or deferred to create additional savings for the end-user.
PV and TDD Financial Return Similarity Adding TDDs to a rooftop PV implementation extends economic benefit to the building owner with financial returns comparable to PV. The figure to the right compares financial returns between typical rooftop PV and TDD deployments. Both TDD or PV systems generate similar financial return for the end user with paybacks as short as four years and rates of return up to 40% per year. Economic metric similarity makes it possible for an end-user to apply a similar decision process for both PV and TDD systems. Economic metric similarity also makes it possible for the PV solution provider to communicate a TDD value proposition to an end-user in a manner similar to PV.
Global Economic Benefit Parity The similarity of financial return between TDD and PV technology is global. When both are deployed in the same location, anywhere in the world, they both generate similar financial returns. This is because the economic benifit from both technologies is driven by the same factors: available sunlight (same in one location), capital expense for equipment (similar for each technology throughout the world) and utility kWh energy cost (same at one facility).
Summary Combining TDDs with rooftop solar PV systems generates additional financial value to both the PV solution provider and the end-user. The basis for this additional value is that TDDS make more roof space available to install more PV panels, more symmetrically. More-symmetrical PV panel arrays decrease PV system cost. A larger PV system generates more revenue for the PV solution provider and more energy savings for the end-user. TDDs save money for end-users by reducing electrical light usage, deferring electric light fixture replacement and reducing HVAC energy usage. The financial returns from a solar PV or TDD investment are similar.
The implementation of VAT in Saudi Arabia commences from Jan. 1, 2018.
The Unified VAT Agreement for the Cooperation Council for the Unified Arab States of the Gulf (the “Agreement”) was approved by KSA by a Royal Decree No. M/51, dated 3/5/1438 H. The Saudi Arabian National VAT Law issued by a Royal Decree No. M113 dated 2/11/1438 H and its corresponding Implementing Regulations were subsequently issued by the Board of Directors of the General Authority of Zakat and Tax (“GAZT”) by Resolution No.3839 dated on 14/12/1438 H.
As per Article 51 of the KSA Value Added Tax – Implementing Regulations, Al Ohood Contracting and Trading and EGPHIL Solar and Renewable Energy Solutions will be required to issue VAT compliant invoices to the recipient of its services.
The Electricity and Cogeneration Regulatory Authority (ECRA) in Saudi Arabia has issued a regulatory framework regarding self-consumption of electricity consumers and export of surplus energy to the national grid using small-scale solar photovoltaic systems.
These regulations aim to promote the connection of small-scale solar PV systems to the distribution system, establish a net metering scheme, as well as ensure efficient and safe construction, installation, maintenance and operation of these PV systems within Saudi Arabia.
Application and Conditions
The Small Solar PV Systems
The consumer may install small-scale solar PV systems under net metering arrangement that has the following conditions:
It should be within the permissible rated capacity as defined under these regulations.
It shall be located in the premises of the consumer.
The systems shall not exceed a capacity of 2 MW in one premise.
It shall not exceed an aggregate capacity of 5 MW in the area of supply at any electricity department.
It shall not be less than 1 kW.
It shall connect and operate safely with the distribution system.
Its connection complies with the Distribution Code requirements, as amended from time to time.
The Net Metering Arrangement
This scheme allows you to receive credit for excess renewable electricity delivered to the grid. Generated surplus electricity shall be exported to the distribution system, recorded in the billing system, and carried forward on one consumption account only. Surplus units will be rolled over for a period of three years. At the end of the period, the distribution service provider (DSP) shall pay the consumer a Tariff prepared by the DSP and submitted to the ECRA for approval.
The Consumers
These regulations apply to all categories of consumers; however, the DSP, which was licensed by ECRA to own and maintain a network on the distribution system, should prioritize the availability of the net metering arrangements of residential, commercial, government, and agriculture consumers.
To qualify as a consumer of small-scale solar PV systems with the net metering scheme, you shall meet the following requirements:
Be a consumer of the DSP
Have the necessary municipal permit(s) and agreements relating to the small-scale solar PV systems
Must be in legal possession of the premises on which the small-scale solar PV system is supposed to be installed
Connect the proposed small-scale solar PV system to the distribution system
The Metering System
The DSP will supply two meters that need to be installed to measure the electricity consumed. The first meter, which the DSP will bear the cost, should be bidirectional – compared to traditional, this meter can provide three readings: delivery, receiving, and the net. It will measure the energy injected and consumed into the distribution system.
The second meter, which the consumer must pay, will measure the electricity generated by the small-scale solar PV. This is also used for small-scale solar PV systems which already reached the capacity, exceeding 100kW. The DSP and the certified contractor or consultant responsible for carrying out the electrical installations work on the systems shall inspect the meter before taking action.
General Connection
The consumer should be able to comply with the following requirements and processes:
Submit a complete application for the connection of the small-scale solar PV system.
Pay the relevant fees and charges for connection and inspection which are set by the DSP and approved by ECRA.
Submit to the DSP an evidence of material compliance with the Saudi or equivalent International standards (PV modules, inverters, etc.)
Only a certified Solar PV contractor or consultant shall carry out the design and specification of the small-scale solar PV system.
A certified contractor or consultant may also be appointed to carry out any electrical installations works and liaise with the DSP on the submittals, drawing approvals, and inspection processes.
The consumer shall obtain the necessary municipal permits prior to connection and energization of the small-scale solar PV installation in accordance with any applicable legislation.
Installation Process
Step 1: Selection of Solar PV Contractor or Consultant
The consumer wishing to install a small-scale solar PV system shall pick a DSP-approved solar PV contractor or consultant who shall be responsible for carrying out electrical installations work. So make sure you choose an authorized person.
Step 2: Solar PV Initial Enquiry
The consumer is required to submit an application form for a small-scale solar PV system connection, including all necessary information and documents regarding the proposed geographical location for the system, and also an application fee.
After the application, the DSP shall carry out an impact study – an assessment of the proposed location from the consumer. They may request the consumer to provide a detailed planning data that is listed from the planning code of the distribution code. This is to govern the relationship between a distribution licensee and its system’s users, ensuring the technical aspects are operated well.
The DSP shall inform the consumer within 20 working days from the submission of the application whether it is approved or not. The approval will be accompanied by a municipality permit which will be valid for 180 days since it was issued.
Step 3: Municipal Permits Application
The consumer shall obtain the following municipal permits of the small-scale solar PV system installation which the certified consultant or contractor can also get:
People safety
Building safety
Small-scale solar PV installation aesthetics to the surrounding area
Step 4: Design Approval
As required by the DSP, a design approval application form shall be submitted by the consumer, including some comprehensive documents and information to be validated. This is to carry out the electrical installation work and to comply with the standards and regulations of electrical installations.
For the approval, the design should maintain the standards of the distribution network which shall notify the consumer and will calculate the connection fees to be charged. Within 10 business days from the payment, two copies of a connection agreement containing the terms and conditions shall be signed by both parties – one copy id for the DSP and the other is for the consumer.
Step 5: Inspection and Energization
Following the construction of the small-scale solar PV system, the consumer then submits an inspection application to the DSP, together with some comprehensive documents. Installation of meters and commissioning tests will follow before the system can be fully energized. The DSP will then issue a final inspection report certifying the successful installation.
DSP Billing and Reporting
Through the use of the metering infrastructure, the DSP shall develop and submit an appropriate consumption bill to ensure efficient communication between the net metering scheme and the customer. The bill shall contain the following information:
The number of energy units exported
The number of energy units imported
Accumulated credit energy units due to surplus energy generated and exported to the distribution system
Net energy units due to credit energy units within the current billing cycle
Carried forward credit energy units for future billing cycles
The DSP will also report to the ECRA on January 31st of each calendar year. The report will include the uptake, total energy units, aggregated peak capacity, the approved and connected installations, as well as the approved small-scale solar PV systems which have not been connected.

A Photovoltaic (PV) System is a power system designed to supply usable solar power by means of photovoltaics – consisting of several components such as DC-AC power inverter, battery bank, system and battery controller, and auxiliary energy sources.
Due to the relatively low maintenance requirements and the long lifetime of many of the system components, solar electric systems are among the most popular renewable energy options available – and that includes commercial photovoltaic systems in Saudi Arabia.
Ranging from small building-integrated systems to large utility-scale power stations of hundreds of megawatts, most PV systems nowadays are grid connected, while off-grid or stand alone systems only account for a small portion of the market.
The two photovoltaic-based systems, Grid Connected and Stand Alone Systems, are classified according to functional and operational requirements, component configuration, and how the equipment is connected to the other power sources and electrical loads.
Grid Connected
An electricity generating solar PV power system that is connected to the utility grid, the grid connected photovoltaic power system (also known as the grid connected PV power system) ranges widely from small residential and commercial rooftop systems to large utility-scale solar power stations. This consists of solar panels, one or several inverters, a power conditioning unit, and grid connection equipment.
Compared to stand alone power systems, a grid connected system rarely includes an integrated battery solution. When conditions are right, the grid connected PV system supplies the excess power back to the grid for which the client can receive rebates in following months.
Advantages of Grid Connected
Easier to install as they don’t need a battery system
Effectively utilizes generated power as there is no storage loss involved
Predictable average reduction of carbon consumption even though the sun doesn’t always shine
Can offset the customer’s electricity usage costs
Stand Alone
Suited for locations that are not fitted with an electricity distribution system, the stand alone power system (SPS), also known as remote area power supply (RAPS), typically includes one or more methods of electricity generation, energy storage, and regulation.
It is usually used as a battery bank; however, other solutions exist including fuel cells. The power drawn directly from the battery is called the Direct Current Extra Low Voltage (DC ELV). This is also used for lighting and DC appliances. This type of photovoltaic power systems is independent of the utility grid and can only use solar panels – it may also be used in conjunction with a diesel generator, wind turbine, or batteries.
Two Types of Stand alone
Direct coupled system
This is a type of stand alone PV system which consists of a solar panel connected directly to a DC load. Since it has no battery banks, there is no energy stored. However, it is capable of powering common appliances during the day.
Stand alone systems with battery
Granted that a direct coupled system has no battery, there is another schematic of a stand alone PV system that has a battery and a charger. The primary functions of a storage battery in a stand alone PV system are:
Energy storage capacity and autonomy
Voltage and current stabilization
Supply surge currents
Photovoltaic Array
If photovoltaic solar panels are made up of individual photovoltaic cells connected together, a system made up of a group of solar panels connected together is called the Solar Photovoltaic Array (also known simply as Solar Array).
In layman’s term, a photovoltaic array is composed of multiple solar panels that are electrically wired together to form a much larger PV system. The larger the total surface area of the array, the more solar electricity it will produce.
Battery Bank
Solar PV Systems often produce energy at times when it’s not needed; hence, they are stored and used when there is no other energy input. Whenever this happens, there are two methods done to the excess energy: it is either sold to the electric utility or stored in batteries. If the second option is chosen, these batteries can discharge rapidly and yield more current than the charging source can provide for itself, helping pumps and motors to run intermittently.
There are two main reasons for deciding to use battery storage:
Maximize savings – The rate paid is normally below the kWh price charged for consumption whenever the production of excess energy is sold to the electric utility. However, other PV system owners save the full price by storing the surplus and only utilizing it when needed, instead of selling at a reduced price.
Back-up power – Store the surplus energy for electric service interruptions.
Considerably, they tend to raise the cost of a PV system, which means savings are only feasible when there is a drastic energy price increase during peak demand hours.
Power Conditioning Unit
Another main component, the Solar Power Conditioning Unit (PCU) acts as an integrated system that consists of a solar charge controller, inverter and a Grid charger. It is responsible for providing the facility to charge the battery bank either through a Solar or a Grid/Distributed Generation (DG) set.
If the battery voltage goes below a set level, the PCU’s jobs is to voluntarily transfer the load to the Grid/DG power and to charge simultaneously – and it’s all because of the constant usage of power. When the solar power or battery charger cannot meet the load requirement, the PCU will give the solar power a preference and will use the Grid/DG power.
AC and DC Disconnect
The Solar PV System has two safety disconnects – the Array DC Disconnect (also known as the PV Disconnect) and the AC Disconnect. The DC Disconnect allows the DC current between the modules to be interrupted before it reaches the inverter. On the other hand, the AC Disconnect separates the inverter for the electrical grid.
For safety reasons, electric systems must be equipped with a manual disconnection device which is made to protect technical personnel from electric shock during system maintenance. Other than its safety functions, the circuit can be interrupted if there is an emergency.
Main Panel
After the output from the PV system has been finally converted to AC power (reaching the adequate frequency), energy can now be provided with the electric utility once connected to the main panel where all electric loads in the building are connected and protected with circuit breakers.

It is now one of the hottest summer months in the country, there is an abundance of daylight supply. People are not used to the extreme heat outside their homes, but daylight also brings so much benefits in our daily lives.
Today, daylighting is considered one of the most efficient environmental strategies that has begun attracting a huge amount of interest in sustainability point of view. However, it’s no longer limited to simply placing transparent or reflective surfaces to provide internal illumination. It requires well-thought innovative product that can maximize its benefits yet limit its concerns.
Daylighting systems in the comforts of your place
Daylighting is controlling the entrance of natural light or direct sunlight in a facility, through the use of transparent and reflective systems, which also reduce electricity consumption.
However, best daylighting systems are composed of daylight-responsive structures which are also designed to avoid direct contact with the sun and reduces harmful rays and heat gain. If enough daylight has been provided, this system can eliminate requirement of electrical lighting.
A Good Daylighting Design
What makes a good design?
If you aim to have a visually stimulating and productive environment in an establishment, there must be significant attention given on the daylighting when doing the architectural design of the building. A good daylighting design is like a puzzle piece – if you forget to consider one part, it will fail the rest.
Remember that the architectural design should meet the following characteristics:
Provision of ambient lighting requirements
Avoid direct light problems through good management (high brightness ratios, direct sunlight controls, etc.)
Must be adjustable and easy to use for the occupants of the facility
Fully implement the overall project goal with its lifetime in consideration.
Things to consider when planning the design
As there are things to watch out during the designing phase, ask yourself these questions:
How appropriate is the daylight in the specific area?
How much light would I need?
What controls do I target?
Is your electric lighting control properly utilized and suited solely for night time functions?
Also remember that the area should have enough sunlight considering the variation expected from the sun.
What are the benefits of daylighting systems?
Reducing costs
Since one of the main advantages of daylighting systems is its attempt to reduce the cost of electric lighting, most buildings with daylighting has a range of 40 to 80 percent savings. Furthermore, these systems also reduce the HVAC (heating, ventilation, and air conditioning) costs.
A natural need for the well-being
Several studies stated that daylighting has a direct effect on a person’s well-being as it improves productivity, emotions, and overall sense of satisfaction in life. These psychological benefits result in reduced absenteeism from offices, as well as improved educational performance and patient recovery time in hospitals.
Healthcare
Remember that proper amount of daylight benefits the overall health of a person. Researches stated that natural light helps in providing mental and visual stimulation necessary for regulating the human circadian rhythm – the 24-hour physiological cycle in living beings that can be regulated by sunlight and temperature.
What is a disadvantage of daylighting systems?
Light and heat that is out of control
If setting up the daylighting project was not properly executed, it can produce risky results. Direct contact with sunlight gives an unpleasant glare and intolerable heat on task surfaces like computer screens – it will make everything difficult for the person who is working.
Tubular daylighting devices are equipment that bring natural light into your place through a sleek and transparent narrow tube. Compared to installation of windows or traditional skylights, these tubes are cost and time efficient – as these can be installed in just a few hours. For you to get all the daylighting benefits, use Solatube’s tubular daylighting systems which EGPHIL and its affiliates aim to correctly design, supply and install.
