FAQs on Solar PV Systems

1. What are photovoltaic (solar) systems or "PV"?

A photovoltaic (PV) system uses PV cells to convert sunlight into electricity. PV cells are made of semiconductors and are used to assemble PV modules, PV systems also include inverters, to regulate and convert the solar-generated electricity from direct current to alternating current. A great advantage of PV systems is that they are fully scalable and vary in size according to the local energy needs, so they can be used for residential, commercial and industrial electricity needs.

A grid-connected PV system is connected to the existing electricity grid. The electricity produced by the system can be used to feed local loads and the surplus is delivered to the electricity grid. This type of system is our main focus, as DEWA Distributed Solar Program deals with PV systems connected to DEWA electricity grid.

2. What are the benefits of installing solar panels for home and business owners?

• Using solar energy produces no air or water pollution and no greenhouse gases emissions. Solar power offers benefits to both homeowners and businesses:
• Reduces electricity bills - installing a solar PV system requires you to undertake an initial investment, but – due to the electricity generated locally – allows you to reduce your electricity bills over lifetime of the system (25 years and beyond for a well maintained installation);
• Increases the value of your property – should you decide one day to sell or rent out your property, it will likely attract a higher price or rent in the market if a PV system is installed. In fact, the new owner or tenant will enjoy lower electricity bills due to the electricity generated locally;
• Reduces your carbon footprint - Your carbon dioxide footprint is a measure of how much carbon dioxide you're releasing into the environment based on your energy-consuming habits. By using solar energy, you will be able to reduce or even erase your carbon footprint;
• Supports Dubai’s economy and ensure its sustainable future. Solar power is locally produced. Every kWh of solar energy that we produce in Dubai reduces our demand for electricity.

3. How does our society collectively benefit from this?

Solar energy is a form of renewable energy which is clean, secure, and limitless. It produces no emissions and does not affect the environment.

Using renewable energy reduces our reliance on diminishing traditional sources of energy, such as gas, oil and coal, ensuring sustainability for future generations.

Renewable energy is a key factor in Dubai’s efforts to foster economic, and social growth while preserving the environment.

In 2011, the Dubai Supreme Energy Council formulated the Dubai Integrated Energy Strategy 2030, which requires renewable electricity sources to contribute to 15% of Dubai power needs. The launch of Mohammed bin Rashid Al Maktoum Solar Park is the first milestone in the path to achieving this vision. The production and use of solar energy by Dubai citizens, businesses and industries will also contribute to this vision becoming a reality.

4. What is the investment cost and break down (equipment, installation, connection and maintenance fee)?

There is no single or simple answer. Capital Expenditure (also known as Capex, or investment cost) depends on a number of factors, such as whether the system is retrofitted or integrated into the building design, the size of the system, and the system components’ manufacturer, retailer, and installer.

Customers also need to take into account Operating Expenditures (Opex) for the annual maintenance of their solar systems (inspection, cleaning of panels, replacement of parts where needed), which can represent roughly 5% of the initial investment.

The cost of the solar PV system will also depend on equipment prices, which follow market conditions and evolve frequently. Currently (Q2 2021) typical system costs are in the 4,500-5,000 AED/kWp range for small ‘villa-size’ systems and in the 3,500-4,000 AED/kWp range or even below for larger ones.

DEWA’s connection fee typically represents a small share of the investment, as a one-off charge currently set at 1,500AED. This amount can also be reduced significantly for small systems (below 10kWp) if no generation check meter is required.

Interested customers can reach out to one of the Solar Contractors or Consultants enrolled with DEWA under Shams Dubai initiative in order to assess feasibility, cost and bill savings of solar PV projects.

5. Are any incentives being provided?

Dubai is currently applying resolution number (46) of 2014 concerning the connections of generators of electricity from solar energy to power distribution system in the emirate of Dubai which was announced by H.H Sheikh Hamdan bin Mohammed Bin Rashid Al Maktoum, the Crown Prince of Dubai and the Chairman of the Executive Council of Dubai.

The new resolution includes a number of provisions regulating the process of consumption and export of electric power from the production unit to DEWA distribution network, where the electricity produced from the production unit is consumed in real estate associated with a single consumption account, In the case of more than one consumption account for the producer, the electricity produced will be consumed in the real estate on the same plot to which the accounts relate. If the amount of electricity produced exceeded the amount of electricity consumed the surplus will be exported to DEWA distribution network through a Net Metering scheme, this surplus energy will be credited and used to off-set future consumption of electricity. The resolution also stipulates that the producer shall not be paid any money for the excess electricity, and set-off between this surplus and the imported energy shall be limited in accordance with the provisions of the resolution and the regulations adopted by the Authority in this regard.

The incentive is therefore the savings on the electricity bill, as you will be purchasing less electricity from DEWA in order to meet your needs. The details on how the Net Metering scheme works can be consulted in the DRRG Connection Conditions document available on Shams Dubai website under ‘Publications and Resources’

6. Are there any tax incentives available for commercial or industrial enterprises for installing solar panels?

No tax or other incentives are currently being offered.

7. What is the estimated return on investment and saving for a residential, commercial, or industrial properties?

The investment return and savings depend on how much electricity you currently use, and the tariff you are paying (see 'Slab Tariff', and how much electricity the photovoltaic system will produce. In general it can be said that the business case for clients with larger consumption and the possibility to install bigger systems is currently more attractive than for clients with low consumption and smaller systems.

You can ask your photovoltaic system provider see (List of Enrolled Electrical & Solar PV Consultants & Contractors) how much your new system will produce on an annual basis and compare that number to your annual electricity demand to get an idea of how much you will save. 

8. Who is involved in the different steps needed to connect a Solar PV system?

DEWA 
Customer 
Consultant /Contractor 
Equipment Manufacturer

9. What are the steps for installing solar systems in homes and public? 

The connection procedure consists of 3 different stages:

Stage A: Getting solar Permits and Connections application
Stage B: Inspection and Connection
Stage C: Generation

For any customer interested in investing in a Solar PV generator, it is recommended to contact one of the solar Consultants or Contractors enrolled with DEWA (List of Enrolled Electrical & Solar PV Consultants & Contractors ) who will act as the customer’s agent and will advise on the best possible solution for their system.

The Consultant/Contractor will gather all the necessary general information required and will then submit the DEWA Getting Solar Permits & Connections application to DEWA (Getting Solar Permits & Connections ).

Upon receiving the Getting Solar Permits & Connections approval, the assigned consultant or contractor and customer will be provided with an estimate / proforma invoice of the applicable connection fee.

Once the installation works have been finalized, the Consultant/Contractor notifies DEWA through the system that the field work has been completed and the installation is ready for inspection (Solar PV Inspection Application ).

The consultant or contractor coordinates with DEWA and the customer to facilitate the site technical inspection, signing of the connection agreement, installation of the meter and connection of the solar PV system to DEWA grid.

Finally, once the system is connected, the customer can generate their own electricity using solar energy and feed any surplus into DEWA’s grid. DEWA will offset the customer’s bill accordingly.

Snapshot of the Connection Process

10. What equipment is needed?

A PV system is made up of different components. These include: 

Solar Panels

Solar panels are the electricity-generating units of a Solar PV system. Most solar panels have a life cycle of up to 25 years, but in some cases this can be longer. They are usually guaranteed by the manufacturer for a certain portion of the lifespan and they undergo a loss of performance over time. Therefore, some minimum efficiency is typically guaranteed. 

Inverter

The Inverter converts the DC electricity produced by the solar panels into an alternating current (AC) that can be used directly in the house or injected into the DEWA network. The Inverter should be located in an airy, safe and accessible area and protected from direct solar radiation and water. Inverters typically have an efficiency above 95% and a general warrantee for 10 years.

Metering System

To measure the electricity generated by the renewable generation unit and electricity consumed in the premises, two energy meters are usually installed:

• The first meter* (Generation check-meter) supplied and installed by DEWA measures the power generated by the photovoltaic system.
• The second meter supplied and installed by DEWA measures the power exported to DEWA grid and the power imported from DEWA grid. During the connection process, the renewable generation unit will be inspected by DEWA before the metering system can be installed. The inspection ensures that the generation unit complies with DEWA technical and safety regulations.

* The PV Generation check-meter can be waived for certain Shams Dubai projects < 10kW:

• In the case of villa communities having a large number of villas equipped with identical or similar small scale installations, the Generation check-meter is required only for a suitable sample of villas to be agreed with DEWA;
• In the case of individual buildings, provided the local area is not already saturated with other similar installations

Interface protection

An automatic decoupling device (also called Interface Protection) should be installed between the inverter and the network connection point, if not yet incorporated in the inverter. This decoupling device stops the PV plant when a problem is detected on the network or when maintenance is needed. This prevents the current from being injected into the network or the electric loads within the premises when the electric power supply has been switched off for safety reasons.

11. Does DEWA have any guidelines relating to the technical specifications of the solar panels and other equipment?

Such specifications are included in the following documents:

• Standards for (Distributed Renewable Resources Generators connected to the Distribution Network)
• Connection guidelines for Renewable Resources Generators connected to medium- and low-voltage distribution networks.
• The manufacturer should provide a certificate proving that their equipment is compliant with these requirements. This certification document will be requested by DEWA during the connection process. A list of eligible equipment can be found on DEWA Website. The list is non exhaustive: you can opt for a manufacturer currently not included in the list as long as the following two conditions are met:
• The equipment must be compliant with DEWA standards
• Proof of such compliance must be sent to DEWA based on the same requirements formulated in the manufacturer equipment eligibility process instructions (PV Equipment Eligibility).

12. Are there any basic criteria that determine whether a certain residential or business unit is suitable for the installation?

Solar panels have truly come a long way. As its popularity increases and installation costs are gradually reduced, a lot of homeowners and businesses nowadays are eager to benefit from this sustainable technology.

The roof orientation, shading and surface area will determine whether you can benefit from this technology as well as the type and size of equipment you require.

We advise you to contact a DEWA enrolled Electrical & DRRG Solar PV Consultant or Contractor that can evaluate your criteria and advise you on the best possible solution for your premises.

There are three factors to be considered when planning to install solar cells onto the building’s envelope:

• Panels orientation to the sun
• Panels inclination
• Potential shadow

The favourable orientation for fixed solar cells in the United Arab Emirates throughout the year is south, and the optimal inclination is about 24 degrees. This typically allows an annual irradiation of about 2100 kWh/m2 for Dubai, when both direct and diffuse radiation are considered.

It is important that panels are kept clean and any deposit of dirt and dust is avoided, since these reduce sensibly the efficiency of the panels. Dubai is in a region prone to dust storms and its accumulation, therefore it is recommended that you clean the PV frequently.

Furthermore, it is advisable to avoid any shadow on the panels because this can cause a significant drop in performance, may damage the module.

A solar system is generally made up of modular components. This means that one can easily replace a malfunctioning component, and possibly extend the system in the future. 

13. Where are the panels usually installed?

Panels are usually installed on the roof rather than on the building façade, to reduce the visual impact and ensure ease of access for cleaning and maintenance. However, PV systems can be blended into almost any imaginable structure. You might find PV being used outdoors for security lighting as well as in parking lot rooftops and bus station shelters. Within the Shams Dubai initiative, ground-mounted panels are not envisaged.

14. Who will be responsible for maintaining the solar panels and related equipment once it is installed?

The maintenance of the system is the responsibility of the customer, who is required to have an operation and maintenance contract with a service provider. As part of the connection process, the customer must present a signed Operation and Maintenance Contract. It is required that the Operation and Maintenance Contract Service providers are enrolled as Electrical & DRRG Solar PV Consultant and Contractors.

15. What is the cost of solar panel technology?

The cost of the system depends on the size as well as the type of system used. Please refer to the answer to question 4 “What is the investment cost breakdown (equipment, installation, connection and maintenance fee”. 

16. Are there any additional costs other than equipment, installation and maintenance fees?

DEWA will charge a one-off connection fee as part of the connection process. No further specific charges will be added to future customer’s bills on an ongoing bases. For most installations, the one-off connection fee will simply equal the fixed amount charged by DEWA for each renewable generator connected to the grid. This amount is currently set at AED 1,500 for each renewable generator, and covers mainly the cost incurred by DEWA for the procurement and installation of the Solar PV generation check meter. This one-off connection fee can be reduced if no Generation check-meter is required.

• The PV Generation check-meter can be waived for certain Shams Dubai projects < 10kW:
  • In the case of villa communities having a large number of villas equipped with identical or similar small scale installations, the Generation check-meter is required only for a suitable sample of villas to be agreed with DEWA;
  • In the case of individual buildings, provided the local area is not already saturated with other similar installations

For large installations (with size above 400 kW) some dedicated equipment might be needed for the proper integration of the renewable generator into DEWA distribution network. In this case, DEWA will charge the cost of such equipment as part of the connection fees. The need for such equipment, will be made known to the applicant in the early stages of the application process, so that the customer will be in a position to take an informed decision on whether to proceed with the project or not. An estimate of the connection fees will then be communicated to the customer in design approval stage. 

17. Who bears the cost of the new meter?

The bi-directional smart meter measuring the electricity exported to and imported from DEWA electricity grid will be installed by DEWA without any additional cost to customers over the normal service charges.

The Generation check-meter, if installed to measure the electricity generated by the PV system, is charged by DEWA as part of the one-off connection fees*.

* The PV Generation check-meter can be waived for certain Shams Dubai projects < 10kW:

• In the case of villa communities having a large number of villas equipped with identical or similar small scale installations, the Generation check-meter is required only for a suitable sample of villas to be agreed with DEWA;
• In the case of individual buildings, provided the local area is not already saturated with other similar installations

1. Is there a limit as to how much solar electricity a DEWA customer can produce?

As per Shams Dubai Connection Conditions (Publications & Resources), the capacity installed should not exceed the applicable share of the Total Connected Load as per Section 2.2 “Limits to capacity of Renewable Generators”. Moreover, DEWA could impose a lower threshold should it be justified by technical limitations related to the integration of your PV system into the power distribution grid.

2. What happens to the energy produced? Is it automatically available for my personal use or is it fed back into the grid?

The electricity produced by the solar panel system is available for your own use and any excess is fed back into the grid. The quantity exported to the DEWA grid is monitored by the meter so that you can be credited on your future electricity bills. 

3. Once produced, where is the energy stored?

While off-grid PV systems depend on rechargeable batteries to store excess electricity, grid-connected systems do not require any storage, as excess electricity can be fed to the distribution grid.

Net-metering programmes provide producers with credit for any electricity they deliver to the grid. 

4. How will energy exported to DEWA be represented on my bill?

The electricity produced by the PV system reduces the amount of energy that a customer has drawn from the grid. If, at any point in time, more energy is produced than consumed, the excess is exported to the grid.

The monthly energy bill will only reflect the net amount of energy consumed as demonstrated in the diagram below:

If during a billing period more energy is exported than imported, the invoiced value of electricity will be zero and the surplus electricity will be shown as a credit which can be brought forward in the following billing period as shown in the diagram below:

Net Producer – Production higher than consumption

The following billing period, the credit will be offset against net consumption. 

If during the course of several consecutive months more energy is produced than imported from the grid, the credit accumulates and is carried over to the following months.

5. How will I be compensated for energy produced?

Any surplus of electricity will be offset from your bills in the following months. An indefinite rollover is applied, so any surplus will be carried forward to the next bill.

6. How is the offsetting of export electricity and electricity credits applied to the slab tariff structure?

As shown in the previous graphs electricity exports within the billing period and electricity credits carried forward from previous billing periods are deducted from the electricity imported from the grid, and only then are DEWA tariff slabs (and any applicable fuel surcharges) applied to calculate the bill. This means more savings for customers, as residual consumption is billed at lower slab rates.

For more details regarding DEWA tariffs and slabs, please visit DEWA website: https://www.dewa.gov.ae/ar-ae/consumer/billing/slab-tariff

7. What if I have multiple accounts with DEWA? Can the electricity generated and exported under one account be offset against consumption of other accounts?

This is possible as long as the other accounts are also located within the same plot. In this case you just need to indicate as part of your application which other accounts you want DEWA to link to the PV generator for offsetting purposes.

8. If I have multiple accounts within a plot of land, in which order will my different accounts be offset?

The account hosting the generator is always the first one, and the order of the subsequent ones will be determined by you during the connection application process. You can optimise your total invoiced amount by choosing an order where the accounts with the highest consumption are offset first.

Please see the diagram below:

9. I own a residential building (or a commercial retail space) and would like to install a solar system for use by different tenants. Can you provide an applicable model that I can use?

Under current legislation it is not planned to offset electricity produced by a PV plant against electricity consumed by different customers. You can only offset electricity consumption of the common areas of the building (lighting, air-conditioning, elevators etc.) measured by the meters you own. Another option is for individual tenants to install solar systems for their own use (tied to their own accounts)

10. What if I decided to sell or rent the property that hosts a solar PV generator, What are my options in this case?

Should you decide to sell or rent the property that hosts your Solar PV generator, you can agree with the new owner or tenant to transfer your generator to their account. However, your accumulated credit cannot be transferred to the new owner’s or tenant’s account.

11. Can I install solar panels in my home/ business premises/ production facility?

PV systems can be installed in your home and in your commercial or industrial premises provided there are suitable conditions for that. PV systems can be blended into a wide range of residential, commercial and industrial building structures.

PV can be used to power your premise's electrical systems, including lights, electrical cooling systems, and appliances.

WARNING:

• All electrical installations, operation and maintenance should be done only by qualified solar PV electricians (DEWA enrolled Electrical & DRRG Solar PV consultants and contractors).
• Under no circumstances should the owner of the solar system interact with its components.
• When exposed to light, photovoltaic (PV) arrays create electrical energy that cause a hazardous condition.

12. How long will it take to assemble the system?

Provided all authorisations required have been obtained, PV installations can be done quickly. A small 10 or 20 kW system can be installed within a week, while a larger, commercial or industrial system may take a few (4-8) weeks. 

13. What are the steps for installing solar systems in homes and public?

The connection procedure consists of 3 different stages:

Stage A: Getting solar Permits and Connections application
Stage B: Inspection and Connection
Stage C: Generation

For any customer interested in investing in a Solar PV generator, it is recommended to contact one of the solar Consultants or Contractors enrolled with DEWA  (List of Enrolled Electrical & Solar PV Consultants & Contractors ) who will act as the customer’s agent and will advise on the best possible solution for their system.

The Consultant/Contractor will gather all the necessary general information required and will then submit the DEWA Getting Solar Permits & Connections application to DEWA (Getting Solar Permits & Connections ).

Upon receiving the Getting Solar Permits & Connections approval, the assigned consultant or contractor and customer  will be provided with an estimate/proforma invoice of the applicable connection fee.

Once the installation works have been finalized, the Consultant/Contractor notifies DEWA through the system that the field work has been completed and the installation is ready for inspection (Solar PV Inspection Application ).

The consultant or contractor coordinates with DEWA and the customer to facilitate the site technical inspection, signing of the connection agreement, installation of the meter and connection of solar PV system to DEWA grid.

Finally, once the system is connected, the customer can generate their own electricity using solar energy and feed any surplus back to DEWA’s grid. DEWA will offset the customer’s bill accordingly.

14. Is there any limit to the size of the PV system that I can install?

As per the Shams Dubai Connection Conditions (Publications & Resources) the capacity installed cannot exceed the applicable share of the Total Connected Load as per Section 2.2 “ Limits to capacity of Renewable Generators”. Moreover, DEWA may impose a lower threshold should it be justified by technical limitations related to the integration of your PV system into the power distribution grid

15. How big a photovoltaic system do I need?

The size of solar PV system you need depends on several factors such as how much electricity you use, the size of your roof, and how much you're willing to invest.

You can contact an electrical Consultant that will help you determine what size and type of system would suit your needs. For a list of DEWA’s registered Consultants and Contractors, please visit the following link: (List of enrolled Solar PV Consultants & Contractors) 

16. What equipment is needed?

A PV system is made up of different components. These include:

• Solar Panels Solar panels are the electricity-generating units of a PV system. Most solar panels have a life cycle of up to 25 years, but in some cases this can be longer. They are usually guaranteed by the manufacturer for a certain portion of the lifespan and they undergo a loss of performance over time. Therefore, guaranteed efficiency is provided by the manufacturer (e.g. usually 90 % after 10 years and 80 % after 25 years).
• Inverter The Inverter converts the DC electricity produced by the solar panels into an alternating current (AC) that can be used directly in the house or injected into the DEWA network. The Inverter should be located in an airy, safe and accessible area and protected from direct solar radiation and water. The efficiency of the Inverter should be greater than 95 % with a general guarantee of 10 years.
• To measure the electricity generated by the renewable generation unit and electricity consumed in the premises, two energy meters are usually installed:
• The first meter* (Generation check-meter) supplied and installed by DEWA measures the power generated by the photovoltaic system.
• The second meter supplied and installed by DEWA measures the power exported to DEWA grid and the power imported from DEWA grid. During the connection process, the renewable generation unit will be inspected by DEWA before the metering system can be installed. The inspection ensures that the generation unit complies with DEWA safety regulations. 



*The PV Generation check-meter can be waived for certain Shams Dubai projects < 10kW:
