Solar Pv Panels

pas-solar advice

When talking about solar panels, it is crucial to determine between two main kinds:

Photovoltaic panels that generate electricity and solar thermal panels that are used for heating. Knowing the types of solar panels helps if you can buy solar panels from a solar equipment shop in dubai.

Solar panels are used to collect solar energy from the sun and convert it into electricity. The typical solar panel types are composed of individual solar cells, each of which is made of layers of silicon, boron, and phosphorus. The boron layer provides the positive charge, the phosphor layer provides the negative charge, and the silicon wafer acts as a semiconductor.

When photons from the sun hit the surface of the panel, they eject electrons from the silicon “sandwich” and enter the electric field generated by solar cells. This results in a directional current, which is then harnessed into usable power.

The whole process is called the photovoltaic effect, so solar panels are also known as photovoltaic panels or photovoltaic panels. A typical solar panel contains 60, 72, or 90 individual solar cells.

Types Of Solar Panels

Solar panels in Dubai come in different types and sizes. Depending on what you’re trying to do, different solar panels may suit your needs better than others – here are some options for you to choose from:

Mono-crystalline Solar Panels

Also known as single crystal panels, these solar panel types are made of a single crystal of pure silicon that is cut into several wafers. Since they are made of pure silicon, they can be easily identified by their dark black color. The use of pure silicon also makes monocrystalline panels the most space-efficient and the most durable among the three types of solar panels.

However, this comes at a cost: a large amount of silicon is wasted to produce a monocrystalline cell, which sometimes reaches more than 50%. This results in a considerable price tag. Yet monocrystalline panels are thought of as the best solar panel types.

There are many types of solar panels but mono-crystalline solar panels are the most efficient. They’re made from silicon which provides more power yields, consumes less space and last longer than other types of solar panel available in UAE. But what sets them apart is their ability to withstand higher temperatures as compared to ordinary polysilicon boards that break down much faster.

With these benefits there also come some disadvantages; they’re expensive to install because they require a lot of raw materials and take up ample spaces due to its large size. Mono-crystalline modules produce no shading lines or dark spots on the surface when generating electricity, creating pure sunlight energy while producing one color which helps towards generating higher levels of efficiency.

Poly-crystalline Solar Panels

As the name implies, these come from different silicon crystals instead of one. Silicon fragments are melted and poured into a square mold. This makes polycrystalline cells, like the LONGI Solar Panels, much more affordable, since there is hardly any waste, and gives them that characteristic square shape.

However, this also makes these solar panel types less efficient in terms of energy and space conversion since their silicon purity and construction are lower than monocrystalline panels. They also have a lower heat tolerance, which means they are less efficient in high-temperature environments.

Polycrystalline solar panels are constructed by melting and casting molten silicon into two curved, parallel sheets which are then carefully peeled apart. This produces a beautiful gemstone pattern, with bright colours as well as areas showing dark spots that mimic the appearance of crystals – although they are actually defects created when the liquid cooled too quickly while crystallizing or experienced mixed chemical doping.

One of the many advantages is that because these panels require less material and do not need higher temperatures for processing, it’s much cheaper than using mono-crystalline solar panels. However there are also some disadvantages; for example, polycrystalline modules provide about 5% less efficiency than monocrystalline modules.

Thin-film Solar PV Modules

Thin film panels are characterized by very thin layers that are thin enough to be flexible. Each panel does not require a frame backing, which makes them lighter and easier to install. Unlike crystalline silicon panels with standardized sizes of 60, 72, and 96 cell counts, thin film panels can come in different sizes to meet specific needs. However, they are less efficient than typical silicon solar panel types.

Thin film solar panels are made up of different materials, chiefly Cadmium Telluride. To make these cells, manufacturers place a layer of CdTe between two thin sheets that conduct electricity – one being a visible light conductor and the other being an opaque sheet protecting the cells from scratches and damage.

They offer tremendous opportunity for less power required projects, but don’t work well when handling outdoor jobs without appropriate care; these cells produce 20.3% efficiency with regular amorphous silicon cells producing 12.5%. These are currently available in UAE due to their flexibility opening up many possibilities for optional applications while they also hold up well against high temperatures.

Amorphous Silicon Solar Cells

Cutting-edge Amorphous Silicon Photovoltaic Glass (ASPG) was developed specifically for architectural use. With its superior aesthetic qualities, unmatched efficiency and unmatched durability – ASPG becomes a perfect substitute to traditional glass windows; offering much more than just the pristine beauty of an ultra-transparent surface without sacrificing any space or function.

The installation process is easy enough that anyone who has ever put up window blinds before can manage it with ease. Other extraordinary benefits include unparalleled resistance against corrosion, security threats and UV radiation which makes these sheets durable enough to last decades upon decades – though we always recommend professional installation!

Passivated Emitter and Rear Cell Panels (PERC)

PERC solar panel types are an improvement of the traditional monocrystalline cell. This relatively new technology adds a layer of passivation to the back surface of the cell that improves efficiency in several ways:

It reflects light into the cell, which increases the amount of solar radiation that is absorbed.
It reduces the natural tendency of electrons to recombine and inhibits the flow of electrons into the system.
It allows greater wavelengths of light to be reflected. Light waves larger than 1180 nm cannot be absorbed by the silicon wafers and simply pass through, so they end up heating the back metal sheet of the cell and reducing its efficiency. The passivation layer reflects these higher wavelengths and prevents them from heating the back sheet.

PERC panels allow for greater solar energy uptake in a smaller physical footprint, making them ideal for limited spaces. They are only a little more expensive to produce than traditional panels, due to the additional materials needed, but they can be manufactured on the same equipment and may end up having a lower average cost per watt due to their efficiency.

Solar Photovoltaic Panels

Photovoltaic (PV) systems are the most used solar panel systems in Dubai. Photovoltaic systems turn sunlight straight into electricity.  Solar cells consist of semiconductors, like silicon, which receive sunlight and turn it into electricity.

Solar cells are linked electrically and sealed in a frame, generally known as a solar panel. When you combine multiple solar panels together, they create a solar array. Finally, when you add the cabling, brackets, inverter, and so forth, the entire system forms your solar panel system. You can learn about solar panels price in Dubai and calculate how much the whole project will cost. Although, you can always find solar panels for sale at Pas Solar.

The electrical conductors are connected to negative and positive terminals, creating an electrical circuit. From there, the electrons can be captured as an electric current. This current, along with the voltage of cells, defines the power that the solar cell can generate, and is how solar panels convert sunlight into electricity.

The cells don’t require direct sunlight to function and can continue to work on cloudy days. Nevertheless, the stronger the sunshine, the more electricity is generated.

Solar PV systems consist of several panels, with each panel generating about 355W of electricity. Regular systems contain around 15 panels and create direct current (DC) electricity. Because the electricity used for house items is alternating current (AC), an inverter is used with the system to convert DC electricity to AC. This electricity can be used in your home, or transferred to the grid. Pas Solar is an official solar inverter distributor. You can contact them to learn how much solar panels cost and if they have a solar panel’s sale.

Solar panel types by Power Capacity

Monocrystalline cells have the highest power capacity among roof solar panel types, thanks to their single crystal construction that allows for higher-rated power in a smaller package. Most monocrystalline panels can generate up to 300w of power capacity.

Recent advances in solar technology have allowed polycrystalline panels to bridge the gap. A standard 60-cell polycrystalline panel is now capable of producing between 240 and 300 W. However, monocrystalline panels still outperform polycrystalline ones in terms of power capacity per cell.

Because thin film panels do not come in uniform sizes, there is no standard measure of power capacity, and the capacity of one thin film panel will differ from that of another based on its physical size. In general, given the same physical footprint, conventional crystalline panels produce more power than thin-film panels of the same size.

Grid-Connected vs. Stand-Alone PV Systems

Grid-connected systems use the local utility grid to guarantee your house is never out of power. If your domestic solar panel system generates more electricity than your home needs daily, the surplus is exported back to the national grid. On the other hand, if you require more electricity than your solar panels have generated, the grid can help you with that. As the main solar panel distributor in Middle East, Pas Solar can help you decide which type of system is suitable for your home.

Stand-alone PV systems are not linked to the grid but, charge a solar battery system. These batteries store the electricity your panels generate. The electricity from these batteries can be used to operate your appliances. Stand-alone systems are used in areas that cannot be connected to a grid and are usually more costly than grid-connected systems because solar batteries can cost quite a lot. There aren’t many places that offer solar panels in Dubai for sale, but if you’re worried about solar panel cost in Dubai, we can help reduce your costs.

4 Main Factors Affecting Solar Panel Efficiency

You would want to maximize your solar panel efficiency to get the most out of the solar panel price you pay and to cut your utility costs. Key factors to consider here are angling, location, size of the solar panel system, direction, regular maintenance, and roof suitability.

1. Location, Direction, and Angle

Is your solar panel system installed and angled, so the solar cells can receive the most sunlight? In Dubai, you need to make sure that your solar panels face sunlight from 9 am to 3 pm.

Assessing your roof’s suitability to withstand solar panels is an important part of figuring out the efficiency of the system. The angle of your roof has a lot to do with how much sunlight your panels will get.

The best direction for solar panels is south-facing, as it would mean the panels face sunlight for the longest period of time. According to Stanford University, a 34° roof tilt angle is the best position for solar panels in Dubai.

2. Roof Suitability

Before you purchase solar panels, you need to consider if the roof is strong enough to stand the weight of the solar panel system. For instance, a 4kW system usually has 16 panels of 250W, which adds up to a total weight of 280 kg.

These, building materials are fit to hold solar panels. It’s just slate and wooden roofs that may not hold that weight. If you’re looking to buy solar panels in Dubai, you can rest assured because buildings in Dubai are generally built using materials that can stand the weight of a solar panel system.

You should consider if your roof is big enough to install solar panels. You will need a minimum of 30 cm of room around your solar panels, so you ought to calculate how much roof space you have available. For instance, a 4kW system with 16 panels needs at least 29 m2 of roof space.

3. Size of the Solar Panel System

Solar panels come in all kinds of shapes and sizes. The larger the solar panel, the more electricity it generates. After calculating your electrical needs, you’ll know what size panels you need.

You can contact a solar panel distributor in middle east to learn the size of their panels and whether you have enough room for them. Monocrystalline panels are known as the most efficient kind of solar panels in Dubai, meaning you will need fewer panels (and thus less roof space) to have as much electricity as a polycrystalline system generates. Contact Pas Solar to learn the mono perc panel price.

4. Maintenance

It’s crucial to carry out the maintenance in order for your panels to function for the longest. Luckily, solar panels do not need much maintenance during their lifespan of 25-30 years.

Have your solar panels inspected regularly by your solar panel wholesaler or by a certified service provider. If you do this on your own, breach your warranty if you damage your panels.

What you can do yourself is make sure your panels are clean all the time. Doing that involves clearing branches and leaves off your solar panels, and washing them with a water hose.

Are solar panels the right choice?

If you are looking for solar panels in Dubai to buy, space is an important factor. The usual system size is around 4.2kWp and will typically need around 29m2 roof area. An unshaded, South-facing roof is perfect for the highest electrical output. East or West-facing roofs can still work fine, but North-facing roofs may not give you the best result. A panel system pointing East or West will generate 15-20% less power than one facing South.

To get a consultation on your available space or solar panels cost, you can contact a solar panel distributor in GCC.

Shaded roofs

Any neighboring buildings, chimneys, or trees can shade your roof and have a bad influence on the performance of your system. Finding an unshaded place is ideal, yet, the shading is sometimes inevitable. Some solar PV systems can lower the influence of shade.

Do I need permission to install solar panels in Dubai?

Solar panels are considered permitted and usually do not need installation permission. Regardless, exceptions exist, and it’s better to check with your local planning office or a solar panel distributor for information.

If you are going to buy solar panels and install them in your home, you must inform your Distribution Network Operator (DNO). The DNO is the organization responsible for providing electricity for your home. Often, your solar panel wholesaler will register for you. The governing system in Dubai has advice on how to register your new energy system. Solar panels in Dubai to buy for reducing your electricity use.

During the day, you will be generating power even on cloudy times, but if you are using more electricity around the house than your system is providing, or during the evening as your panels are not generating any power, you will be making up for this by receiving electricity from the grid. Lowering your power use can help reduce your utility cost and lower your carbon footprint.

Use more power during day

As your solar system works at its peak during the day, it is a fine idea to use your electrical appliances like your dishwasher, washing machine, and iron during daylight hours. If you are at home, this may be easier, but if you are away during the day, you can try setting a timer for your washing machine and dishwasher.

A lot of times solar panels can produce more electricity than you need and depending on the solar panels price in Dubai, you would want to get the most return on your investment.

Combine with other renewable systems

You can integrate solar PV with renewable technologies like solar hot water systems or heat pumps. These technologies function well with each other because solar PV can help power a heat pump, for instance.

Installation of Solar panels

Solar panel systems require little maintenance. Keep an eye on adjacent trees to make sure they do not overshadow your system.

In Dubai, panels that are tilted at 15 degrees or more benefit from being rinsed by rain, and that helps ensure the best performance. Debris usually builds up if you install ground-mounted panels, or if you live in areas with more debris in the air. In such cases, you may need to have the panels cleaned from time to time.

Once fitted, your solar panel distributor should make written details of any maintenance inspections that they should carry out to ensure everything is functioning properly. This can include details of the primary inverter fault signals and key troubleshooting suggestions. Ideally, your solar panel wholesaler should show this to you as they sell solar panels and when the system has been installed.

Keeping a close eye on your system and the amount of power it is producing (and the weather conditions) will help you know what to expect and warn you when something might go wrong.

The panels usually last up to 25 years or more, but the inverter will likely need replacing sometime during this period, which can cost around $900 (depending on panels size and manufacturer). Some solar inverter distributeor offer online monitoring solutions and can alert you by email if your system fails.

Solar inverters often have warranties of five years as a minimum, that can often be extended for as long as 15 years. Contact your solar panel wholesaler about the potential lifespan and advantages of an extended warranty. You might see that a 15-year warranty costs about as much as a substitute inverter, so consider that carefully.

Can I install a PV diverter?

PV diverters are a low-cost and low-maintenance choice for raising your own consumption of solar electricity.

Most of the time, solar PV systems either:

Are not generating enough power for your household demands, and are supplemented by receiving power from the grid, or are providing surplus electricity beyond your demand and returning the electricity back to the grid.

Instead of transmitting surplus electricity to the grid, a PV diverter switch can power the heater in your hot water tank, storing hot water for your later use. To get information about solar panels price in Dubai and the costs of installing a PV diverter, contact a solar panel distributor in GCC.

Solar panel types by Cost

Monocrystalline panels (or modules, as they are technically known) have a high price, due to their inefficient and energy-intensive manufacturing process with only a 50% yield for each silicon crystal.

Polycrystalline modules are cheaper because they make use of the leftover crystal fragments from monocrystalline production, resulting in a simpler manufacturing process and lower production costs.

Among the different solar panel types, CIGS is the most expensive, followed by CdTe and amorphous silicon. In addition to the lower solar panels cost, thin-film modules can be easier to install thanks to their lower weight and flexibility, which reduces labor costs.

While the total cost of residential systems has decreased by more than 65% in the last decade, the system’s total cost has increased from 58% of the total system cost in 2014 to 65% in 2020.

How much do solar panels cost ?

A regular domestic solar panel system is 4.2kWp and costs around $7500. Although, Pas Solar can offer you solar panels for sale. The amount you pay is affected by the size of the panels and will be influenced by any difficulties regarding accessing your roof.

Costs are also influenced by whether or not you prefer tiles or panels, and whether you choose building-integrated panels or buy panels that are mounted on top of your roof. Panels on rooftops are the most affordable option, while tiles are the most costly for the same system.

If you have more questions about Solar Panels or canadian solar panels in dubai price, contact our technicians. Some distributors often offer solar panels in sale, so keep an eye out for that.

Can I make money using my solar panel system?

Export payments With any solar panel system, there will be occasions when the power you generate is more than you can use or store, so the extra electricity will be exported to the grid to be used by someone else. If you intend to be paid for exporting, you have to make sure you are getting your export payment.

All you need to do is find an energy company that will pay you for this surplus. For more information call your solar panel wholesaler and ask them the solar panel price.
