590 Watt Bifacial Solar Panels: Price, Specifications, Benefits & Best Brands in Pakistan (2026)

590 watt bifacial solar panels are high-power solar modules designed to generate electricity from both the front and rear sides of the panel. With a rated output of around 590 watts per panel, they can help solar users install higher-capacity systems with fewer panels.

Bifacial technology can also capture reflected and scattered sunlight reaching the rear side of the module. However, the additional energy produced from the back depends on the installation design, panel height, surface reflectivity, shading, and weather conditions.

In Pakistan, 590W bifacial panels are available from major manufacturers such as Jinko Solar, LONGi, JA Solar, Canadian Solar, and Trina Solar. But choosing the right panel requires more than comparing wattage and price.

This guide explains the 590 watt bifacial solar panels price in Pakistan, specifications, efficiency, bifacial gain, popular brands, power generation, installation requirements, advantages, disadvantages, and important buying tips.

Quick Answer: Are 590W Bifacial Solar Panels Good?

Yes, 590 watt bifacial solar panels can be an excellent choice for residential, commercial, agricultural, and large-scale solar installations.

Their main advantages are:

• High power output
• Electricity generation from the front and rear sides
• Potentially higher energy yield
• Fewer panels required for a particular system size
• Modern N-type options
• High efficiency in many newer models
• Suitable for large rooftop and ground-mounted systems

However, bifacial panels do not automatically produce twice as much electricity. Their additional rear-side generation depends on how much useful light reaches the back of the panel.

What Is a 590 Watt Bifacial Solar Panel?

A 590 watt bifacial solar panel is a photovoltaic module with a front-side rated power output of approximately 590 watts under standard test conditions.

The term bifacial means the panel can generate electricity from both sides.

A conventional monofacial solar panel mainly generates electricity from sunlight falling on its front surface. A bifacial module can also use light reaching its rear side.

The rear side can receive:

• Reflected sunlight
• Diffuse sunlight
• Light reflected from the ground
• Light reflected from a roof or other surface

This additional light can increase the total energy generated by the module.

Important: 590W Does Not Mean 1,180W

A common misunderstanding is that a 590W bifacial panel produces 590W from the front plus another guaranteed 590W from the back.

That is incorrect.

The 590W rating refers to the panel’s rated front-side power under specified test conditions. The rear-side contribution is additional and depends on the actual installation environment.

How Do 590W Bifacial Solar Panels Work?

The working principle is straightforward.

Front Side

The front side receives direct sunlight and converts it into electricity through photovoltaic cells.

Rear Side

Some sunlight is reflected from the ground or roof toward the back of the panel. The rear cells can capture part of this light.

The simplified process is:

Sunlight → Front side → Solar cells → Electricity

and:

Reflected/diffuse light → Rear side → Solar cells → Additional electricity

The amount of additional electricity varies from one installation to another.

This is why the mounting structure and surface underneath the panels are important for bifacial systems.

590 Watt Bifacial Solar Panel Price in Pakistan in 2026

The price of a 590 watt bifacial solar panel in Pakistan varies according to the brand, exact model, cell technology, efficiency, warranty, panel grade, seller, and market availability.

For August 2026, a reasonable indicative market range for 590W-class bifacial panels is approximately:

Brand	Power Class	Approx. Price per Panel in Pakistan
Jinko Solar	590W class	PKR 24,000–27,000
LONGi	590W class	PKR 24,000–27,000
JA Solar	590W class	PKR 22,500–25,500
Canadian Solar	590W class	PKR 23,000–27,000
Trina Solar	590W class	PKR 23,000–27,000

These are approximate market prices for August 2026, not fixed manufacturer prices. Solar panel prices can change because of exchange rates, imports, stock availability, seller margins, model changes, and market demand.

Recent Pakistan market listings have shown examples such as:

• Jinko 585/590W: around PKR 24,570–24,900
• LONGi 585/590W: around PKR 23,985–25,740
• JA Solar 585/590/595W: around PKR 22,567–24,862

Before purchasing, confirm the exact model number and current price with the seller.

Price Per Watt

Price per watt is another useful way to compare solar panels.

For example, if a 590W panel costs PKR 25,000:

PKR 25,000 ÷ 590W = approximately PKR 42.37 per watt

However, price per watt should not be the only buying factor. Also compare efficiency, bifaciality, temperature coefficient, degradation, warranty, dimensions, and manufacturer reputation.

590W Bifacial Solar Panel Specifications

Specifications vary from one model to another, but these are the main values you should check.

Rated Power

Approximately 590W.

Module Efficiency

Efficiency tells you how effectively the panel converts available sunlight into electricity.

A higher-efficiency panel can produce more power from a similar amount of roof space.

Bifaciality

Bifaciality indicates the rear-side performance capability relative to the front side under specified test conditions.

A higher bifaciality rating can be beneficial when the installation provides good rear-side light.

Cell Technology

Many newer 590W-class panels use N-type technologies such as TOPCon, although the exact technology depends on the model.

Glass Construction

Many bifacial panels use dual-glass construction, which can provide a durable design suitable for outdoor installations.

Temperature Coefficient

Solar panels produce less power as their cell temperature increases.

A lower absolute temperature coefficient is generally beneficial in hot climates such as Pakistan.

Dimensions and Weight

590W panels are often physically large.

Always measure your available roof area before purchasing.

How Much Electricity Does a 590W Solar Panel Produce?

A 590W panel has a rated capacity of:

590W = 0.59kW

If it operated at its rated output for one hour:

0.59kW × 1 hour = 0.59kWh

But solar panels do not operate at their rated output throughout the entire day.

A simple example using 5 peak-sun-hours is:

0.59kW × 5 hours = 2.95kWh per day

This is only a simplified theoretical calculation.

Actual generation depends on:

• Sunlight
• Weather
• Temperature
• Panel orientation
• Tilt
• Shading
• Dust
• Inverter losses
• Cable losses
• Panel condition
• Bifacial rear-side contribution

Therefore, do not use 2.95kWh as a guaranteed daily output.

How Much Extra Power Can a Bifacial Panel Produce?

There is no single percentage that applies to every bifacial installation.

The additional rear-side gain depends on:

• Ground or roof reflectivity
• Panel height
• Panel spacing
• Row spacing
• Panel orientation
• Rear-side shading
• Sun position
• Local weather
• Surface albedo

A panel mounted very close to a dark roof may receive little useful rear-side light.

A raised panel installed above a reflective surface may receive considerably more.

Therefore:

Bifacial gain depends on installation design.

Does Roof Color Affect Bifacial Solar Panel Performance?

Yes.

The surface below a bifacial panel can affect how much light is reflected toward the rear.

A lighter or more reflective surface can provide more reflected light than a dark surface.

This is often described using the term albedo.

For example, light-colored surfaces may reflect more sunlight than dark surfaces.

However, changing your roof purely to increase bifacial generation is not always economically worthwhile. The additional cost should be compared with the expected increase in electricity generation.

Why Panel Height Matters for Bifacial Solar Panels

The rear side needs access to light.

If a panel is installed extremely close to the roof, very little light may reach the back.

Increasing the distance between the panel and roof can improve rear-side exposure.

But higher mounting also increases:

• Wind loading
• Structural requirements
• Mounting material
• Installation complexity
• Potential installation cost

The goal is to find a safe and practical mounting height, not simply the highest possible position.

590W Bifacial Solar Panels for Home Solar Systems

590W panels can be useful for residential solar systems when the roof has sufficient space and the inverter is compatible.

For example, a simple calculation for approximately 5kW of panel capacity is:

5,000W ÷ 590W = 8.47 panels

Because you cannot install part of a panel, 9 panels would provide:

9 × 590W = 5,310W

This is approximately a 5.31kW DC array.

The final system design may be different because the installer must consider:

• Inverter capacity
• MPPT voltage range
• Maximum input current
• Roof layout
• Shading
• String configuration
• Electrical requirements

590W Bifacial Panels for a 10kW Solar System

For a system with approximately 10kW of DC panel capacity:

10,000W ÷ 590W = 16.95 panels

17 panels would provide:

17 × 590W = 10,030W

This is approximately a 10.03kW DC array.

However, the number of panels should never be selected using wattage alone. The inverter’s voltage and current limits must also be checked.

590W Bifacial vs 550W Solar Panels

A 590W panel has a higher rated output than a 550W panel, but that does not automatically make it a better purchase.

Compare:

Factor	590W Bifacial	550W Panel
Rated output	Higher	Lower
Rear-side generation	Yes	Depends on model
Panel count for same capacity	Potentially lower	Potentially higher
Physical size	Often larger	Often smaller
Roof suitability	Depends on roof	May suit smaller roofs
Installation requirements	Can be higher	Depends on model
Best choice	Depends on system	Depends on system

If your roof is large and the installation supports bifacial generation, 590W bifacial panels may be attractive.

If your roof has limited space or difficult dimensions, a smaller panel may fit better.

Advantages of 590 Watt Bifacial Solar Panels

1. High Power Output

A 590W panel provides high rated power per module.

This can reduce the number of panels needed for a particular system capacity.

2. Rear-Side Energy Generation

The bifacial design allows the rear side to capture useful reflected and diffuse light.

3. Potentially Higher Energy Yield

With the right installation environment, bifacial panels can produce more total energy than a comparable monofacial installation.

4. Fewer Panels for Large Systems

Higher-wattage modules can reduce the number of individual panels needed.

5. Modern Cell Technologies

Many current 590W-class modules use N-type technologies.

6. Suitable for Large Installations

They can be useful for:

• Commercial buildings
• Factories
• Warehouses
• Agricultural projects
• Ground-mounted solar
• Large residential systems

Disadvantages of 590 Watt Bifacial Solar Panels

1. Large Physical Size

A 590W panel can take up significant roof space.

2. Higher Weight

Dual-glass bifacial panels can be heavier than some single-glass panels.

3. Rear-Side Gain Is Not Guaranteed

If the rear receives little light, the bifacial advantage may be limited.

4. More Careful Installation Design

Panel height, spacing, surface reflectivity, and structure can affect bifacial performance.

5. Potentially Higher Upfront Price

Some bifacial N-type modules can cost more than conventional panels.

Are 590W Bifacial Solar Panels Good for Pakistan?

Yes, they can be a good option for Pakistan, particularly where the installation has:

• Strong sunlight
• Adequate roof or ground space
• Suitable mounting height
• Good rear-side light exposure
• A compatible inverter
• Proper electrical protection

Pakistan’s hot climate makes the temperature coefficient particularly important.

You should also check the panel’s:

• Mechanical load rating
• Temperature specifications
• Hail resistance
• Warranty
• Degradation rate
• Glass construction

Solar Panel Temperature and 590W Bifacial Performance

Solar panels are tested under standard laboratory conditions, but real-world conditions are different.

When panel temperature rises, electrical output generally decreases.

This is why two panels with the same 590W rating can perform differently under high temperatures.

When comparing panels for Pakistan, check the manufacturer’s temperature coefficient of Pmax.

A better temperature coefficient can help limit power loss as module temperature increases.

590W Bifacial Panel and Inverter Compatibility

Before connecting a 590W panel to an inverter, the installer should check the complete electrical specifications.

Important values include:

• Voc
• Vmp
• Isc
• Imp
• Maximum system voltage
• Maximum input current
• MPPT voltage range

The number of panels connected in each string must also be designed correctly.

Do not choose the string configuration based only on the 590W rating.

The panel datasheet and inverter specifications must be matched.

Best Mounting Structure for 590W Bifacial Panels

A suitable mounting structure should:

• Support the panel weight
• Resist expected wind loads
• Provide appropriate panel clearance
• Allow rear-side light exposure
• Protect against corrosion
• Keep panels securely fixed
• Allow maintenance access

For bifacial panels, avoid structures that unnecessarily block the rear surface.

Can 590W Bifacial Panels Be Installed on a House Roof?

Yes.

However, residential roofs often contain:

• Water tanks
• Boundary walls
• Rooftop rooms
• Trees
• Satellite dishes
• Air-conditioning units
• Other equipment

These can create shading and reduce the available installation area.

Because 590W panels can be large, measure your roof before purchasing them.

A professional site survey is strongly recommended.

590W Bifacial Solar Panels for Commercial Solar Systems

High-power bifacial panels can be especially useful for commercial projects.

Businesses may benefit from:

• Higher DC capacity
• Fewer modules
• Potentially higher energy yield
• Efficient use of installation space
• Bifacial generation

Commercial installations can also have more freedom to optimize:

• Panel height
• Row spacing
• Surface reflectivity
• Orientation
• Maintenance access

This can make it easier to take advantage of bifacial technology.

What to Check Before Buying a 590W Bifacial Solar Panel

Don’t buy a panel simply because the seller says “590W bifacial.”

Check these specifications first.

1. Exact Model Number

Always ask for the full model number.

2. Original Datasheet

Request the manufacturer’s datasheet.

3. Efficiency

Compare module efficiency with competing panels.

Common Mistakes When Buying 590W Bifacial Solar Panels

Mistake 1: Choosing Only by Wattage

590W does not automatically mean better quality.

Mistake 2: Expecting Double Power

Bifacial does not mean a 590W panel automatically produces 1,180W.

Mistake 3: Ignoring Roof Dimensions

A high-power panel may not fit your roof layout.

Mistake 4: Ignoring Rear-Side Light

Without useful rear-side light, bifacial gain can be limited.

Mistake 5: Buying the Cheapest Panel

An unusually cheap panel may have different specifications, grade, warranty, or condition.

Mistake 6: Ignoring Temperature Performance

Pakistan’s high temperatures make thermal performance important.

Mistake 7: Not Checking the Datasheet

Always verify the exact model.

Mistake 8: Ignoring Inverter Compatibility

Panel voltage and current must match the inverter’s operating limits.

590W Bifacial Solar Panel Maintenance

Bifacial panels generally do not require complicated maintenance, but regular inspection is useful.

Keep the Panels Clean

Dust and bird droppings can reduce the amount of sunlight reaching the panel.

Clean the panels when dirt visibly accumulates or when performance appears to decline.

Check the Cables

Inspect for:

• Loose cables
• Damaged insulation
• Exposed connections
• Sagging cables
• Water damage

Monitor Solar Generation

If your inverter has monitoring, check production regularly.

A sudden decrease may indicate:

• Shading
• Dirt
• Inverter problems
• Electrical faults
• Panel damage

590W Bifacial Solar Panel: Pros and Cons at a Glance

Pros	Cons
High 590W rated output	Large panel size
Front and rear generation	Rear-side gain depends on installation
Potentially higher energy yield	Can be heavier
Fewer panels for larger systems	May require stronger mounting
Many N-type options	Some models cost more
Good for commercial projects	Not ideal for every roof
Suitable for reflective surfaces	Requires proper inverter matching

Final Verdict: Should You Buy a 590W Bifacial Solar Panel?

590 watt bifacial solar panels can be an excellent choice for modern solar systems, particularly when high power output, limited panel count, and additional rear-side generation are valuable.

But don’t choose a panel simply because it says 590W.

Before buying, compare:

• Exact model
• Efficiency
• N-type/TOPCon technology
• Bifaciality
• Temperature coefficient
• Product warranty
• Performance warranty
• Degradation rate
• Dimensions
• Weight
• Price per watt
• Inverter compatibility
• Manufacturer documentation

The most important point is that bifacial performance depends on the complete installation.

A 590W bifacial panel installed above a suitable reflective surface with good rear-side light exposure can take better advantage of bifacial technology than the same panel installed directly above a dark roof with very little rear-side light.

For buyers in Pakistan, compare at least two or three exact models, check the current market price, verify the original datasheet, and choose the panel that provides the best combination of performance, warranty, price, and suitability for your solar system.
