Adani 545W Bifacial DCR Solar Panel: Price, Specifications & Buying Guide

November 11, 2026

The demand for high-efficiency solar panels has increased as homeowners, businesses and solar installers look for better power output from limited rooftop space. Bifacial solar panels are particularly interesting because they can generate electricity from both the front and rear sides of the module.

The Adani 545W Bifacial DCR Solar Panel is one of the higher-wattage Adani modules available for Indian solar projects. It is listed in the Adani Elan Shine range and is available through solar distributors and retailers in DCR configurations.

However, there is an important point buyers should understand before purchasing. Adani has 545W bifacial modules from different technology generations, including Mono PERC and N-type TOPCon products. Therefore, the exact model number and datasheet should always be checked before using specifications from an online listing.

This guide covers the Adani 545W bifacial DCR panel price, specifications, bifacial technology, estimated generation, DCR requirements, inverter compatibility and buying considerations.

Adani 545W Bifacial DCR Solar Panel Price in India

The price of the Adani 545W bifacial DCR panel varies depending on the exact model, technology, supplier, quantity, GST and delivery location.

A current solar-product listing shows the Adani Solar 545W Bifacial DCR Elan Shine panel at ₹12,235 + GST, equivalent to approximately ₹22.45/W before GST.

Another supplier lists an Adani DCR bifacial 530W to 550W Mono PERC family at around ₹25/W, demonstrating that dealer pricing can vary depending on model and commercial terms.

Price reference	Indicative price
Current listed 545W DCR panel	₹12,235 + GST
Approx. price per watt	₹22.45/W
Other dealer range for 530–550W DCR family	Around ₹25/W

These are market reference prices, not a guaranteed Vigood Solartek selling price. Solar-panel prices can change frequently based on stock, procurement quantity, freight and supplier margins.

Before placing an order, ask for a quotation against the exact model number.

Why can the same 545W panel have different prices?

The final price may change because of:

Cell technology
DCR classification
Bifacial or monofacial construction
Product generation
Order quantity
GST
Transportation
Dealer margin
Warranty and documentation

A ₹/W comparison is useful, but only when the panels being compared have similar technology, warranty and DCR status.

Adani 545W Bifacial DCR Solar Panel Specifications

The 545W Adani bifacial range needs careful model verification because online listings can combine multiple generations.

A current listing identifies the Adani 545W panel as an Elan Shine bifacial DCR module.

Adani's official downloads library contains separate documentation for its Shine TOPCon and Mono PERC module families, which reinforces the need to match the exact SKU with the correct datasheet.

For the 545W class, buyers should verify the following parameters on the supplied panel's datasheet:

Parameter	What to verify
Rated power	545Wp
Brand	Adani Solar
Module type	Bifacial
DCR	Confirm for exact SKU
Cell technology	Confirm whether Mono PERC or TOPCon
Cell configuration	Confirm from exact datasheet
Vmp	Confirm from exact datasheet
Imp	Confirm from exact datasheet
Voc	Confirm from exact datasheet
Isc	Confirm from exact datasheet
Module efficiency	Confirm from exact datasheet
Dimensions	Confirm from exact datasheet
Weight	Confirm from exact datasheet
Maximum system voltage	Confirm from exact datasheet
Warranty	Confirm current applicable warranty

Why are we not publishing one fixed technical specification table?

This is intentional.

Adani's current downloads page contains separate datasheets for different generations, including Shine TOPCon G2G, Shine TOPCon G2TB, Shine G2G and Shine G2TB modules.

Using the electrical specifications of one generation for another 545W product could create an inaccurate product page.

For an ecommerce listing, the model number printed on the actual panel should always be the source of truth.

What Is a Bifacial Solar Panel?

A bifacial solar panel is designed to generate electricity from sunlight reaching both the front and rear surfaces of the module.

The front side receives direct sunlight, while the rear side can capture reflected and scattered sunlight from the surrounding surface.

This additional production is called bifacial gain.

For example, a 545Wp panel has a front-side rated output of 545W under Standard Test Conditions. It does not mean that the panel will continuously produce 545W in real-world conditions.

The actual output depends on:

Solar irradiation
Temperature
Tilt and orientation
Shading
Dust
System losses
Roof or ground reflectivity
Rear-side exposure

What Determines Bifacial Gain?

Bifacial panels are particularly dependent on their installation environment.

1. Ground or roof reflectivity

A light-coloured or highly reflective surface can send more light toward the rear of the panel.

A dark surface may produce considerably less rear-side reflection.

2. Mounting height

A greater distance between the panel and the surface can allow more reflected light to reach the rear side.

3. Module spacing

The arrangement of the solar array affects rear-side exposure. Closely packed modules can reduce the amount of reflected light available to the rear surface.

4. Shading

Walls, parapets, equipment and other structures can reduce rear-side irradiance.

5. Mounting structure

The mounting system should avoid unnecessarily blocking the rear surface.

Therefore, bifacial does not mean a guaranteed fixed percentage increase in generation.

The actual gain must be estimated according to the project design.

Adani 545W Solar Panel Generation Estimate

The rated capacity of the panel is 545Wp.

To illustrate potential front-side generation, assume:

Panel capacity: 545Wp
Peak sun hours: 5 hours/day
Overall performance ratio: 80%

The estimated generation is:

545 × 5 × 0.80 = 2.18kWh/day

So, under these assumptions:

Period	Illustrative generation
Per day	2.18 units
30 days	65.4 units
365 days	795.7 units

These are planning estimates only.

Actual generation may be lower or higher depending on location, season, weather, shading, temperature, system losses and maintenance.

A bifacial installation may generate additional energy from the rear surface, but that additional generation should not be treated as guaranteed.

How Many Adani 545W Panels Are Needed?

The number of panels depends on the required DC capacity.

Target system size	Panels required	Total DC capacity
1kW	2	1.09kWp
2kW	4	2.18kWp
3kW	6	3.27kWp
5kW	10	5.45kWp
6kW	12	6.54kWp
10kW	19	10.355kWp

These calculations represent the nominal DC panel capacity.

They do not mean that a 5.45kWp panel array should automatically be connected to any 5kW inverter.

The inverter must be checked for:

Maximum PV input power
Maximum DC voltage
MPPT voltage range
Maximum input current
Maximum short-circuit current
Number of MPPTs
Permitted DC oversizing

Adani 545W Panel and Inverter Compatibility

The panel and inverter must be designed as one electrical system.

For example, connecting multiple panels in series increases the string voltage, while connecting strings in parallel increases current.

The designer must ensure that the string voltage remains inside the inverter's MPPT operating range.

At the same time, the maximum string Voc must remain below the inverter's maximum DC voltage, including the effect of low-temperature conditions.

Important checks before connecting the panel

Maximum PV voltage: The total string Voc must remain within the inverter's permitted DC voltage.

MPPT range: The operating voltage of the string should remain inside the inverter's MPPT range.

Current: The panel's operating and short-circuit current must be compatible with the inverter's MPPT current limit.

Bifacial contribution: Rear-side illumination can affect module current, so the installer should consider the applicable design conditions.

Temperature: Panel Voc changes with temperature. String design should account for the lowest expected operating temperature.

Never design the string purely from the panel's wattage.

What Does DCR Mean?

DCR means Domestic Content Requirement.

In the Indian solar sector, DCR requirements are relevant to certain government-supported projects and schemes where domestically manufactured solar cells and modules are required.

A panel being sold by an Indian company or being assembled in India does not by itself establish DCR compliance.

The exact module and its documentation should be checked.

What should you verify?

Before buying an Adani 545W DCR module, confirm:

Exact model number.
DCR status of that model.
Manufacturer documentation.
Applicable approved-list requirements.
Module serial number.
Original invoice.
Current government-scheme requirements.

Is Adani 545W DCR Panel Eligible for PM Surya Ghar Subsidy?

DCR modules are relevant to residential solar installations where the applicable scheme requirements require domestic-content modules.

However, buying a DCR panel does not automatically guarantee a subsidy.

The complete project must satisfy the applicable PM Surya Ghar requirements, including the installation process, approved vendor requirements and other scheme conditions.

Therefore, consumers should not make a subsidy decision based solely on the word "DCR" printed on a product listing.

Adani 545W Bifacial DCR vs Monofacial Solar Panel

A bifacial panel can capture light from the rear side, while a conventional monofacial panel primarily uses the front side.

Feature	Adani 545W Bifacial DCR	Conventional Monofacial
Front-side generation	Yes	Yes
Rear-side generation	Yes	No
DCR availability	Model dependent	Model dependent
Installation sensitivity	Higher	Lower
Benefit from reflective surfaces	Higher	Limited
Suitable for elevated structures	Yes	Yes
Rear-side clearance	Important	Less important

For a rooftop where the panel is mounted very close to an opaque surface, the additional benefit of bifacial technology may be limited.

For elevated or appropriately designed structures, bifacial technology can have greater potential.

Adani 545W Bifacial DCR vs 550W Bifacial

A difference of 5Wp between two modules is relatively small.

For example:

545W × 10 panels = 5.45kWp
550W × 10 panels = 5.50kWp

The difference is only 50Wp across ten modules.

Therefore, choosing between a 545W and 550W panel should not be based solely on the wattage difference.

Consider:

Price per watt
Efficiency
Dimensions
Weight
Cell technology
DCR classification
Warranty
Electrical specifications
Availability
Inverter compatibility

A slightly lower-wattage panel can sometimes offer better value if its price and specifications are more suitable.

Is the Adani 545W Bifacial DCR Panel Good for Rooftop Solar?

It can be a suitable choice for a rooftop project when the exact panel specifications match the installation requirements.

However, buyers should consider the physical size of the module.

High-wattage panels can be physically larger and heavier than older 400W to 450W modules. Rooftop access, handling and mounting structure therefore become important considerations.

Before installation, check:

Available usable roof area
Roof structure
Panel dimensions
Panel weight
Mounting structure
Shading
Rear-side clearance
Inverter compatibility
Cable routing

Important Buying Checklist

Before ordering an Adani 545W bifacial DCR solar panel, use this checklist:

1. Check the exact SKU

The exact model number should appear on the quotation and product label.

2. Confirm DCR status

Ask the supplier to provide appropriate documentation confirming DCR status for the exact module.

3. Confirm technology

Adani has both Mono PERC and TOPCon product families.

Do not assume that every 545W panel is TOPCon.

4. Check electrical specifications

Verify:

These values are essential for string design.

5. Check dimensions and weight

Make sure the mounting structure can safely support the actual module.

6. Check warranty

Confirm the applicable product warranty and linear power warranty for the exact module generation.

7. Check invoice and serial number

Keep the original invoice and product documentation for warranty and scheme-related requirements.

8. Check bifacial specifications

If the project is specifically designed around bifacial generation, verify the manufacturer's stated bifaciality and installation recommendations.
