Astronergy 635W Bifacial Solar Panel

Astronergy 635W Bifacial Solar Panel Overview

The Astronergy 635W Bifacial Solar Panel combines high rated output with N-type TOPCon cell technology and a dual-glass structure. Its 635W power rating makes it a practical option for projects that need substantial power from each installed module.

The bifacial design allows the rear side to contribute to electricity generation when reflected or scattered sunlight reaches the cells. However, the additional energy depends on ground reflectivity, mounting height, row spacing, shading and the overall installation layout. Therefore, rear-side generation should be treated as site-dependent rather than a fixed percentage.

The panel achieves 22.7% module efficiency and has a power temperature coefficient of -0.29%/°C. These features are useful when assessing solar modules for installations exposed to Pakistan’s summer temperatures. In addition, proper mounting, ventilation, cleaning and electrical system design help support reliable operation.

Astronergy 635W Solar Panel Features and Benefits

N-Type TOPCon 4.0 Technology

This panel uses N-type monocrystalline TOPCon 4.0 cells. The technology supports high-output module construction. In addition, the panel’s rated efficiency helps installers assess how much power can fit within the available installation area.

Bifacial Solar Energy Generation

The module generates electricity from its front and rear sides. As a result, installations that allow sufficient light to reach the rear surface may gain additional energy.

However, the actual gain varies by project. For example, a rooftop with limited rear illumination may provide less additional generation than a well-designed ground-mounted system with a reflective surface.

High Module Efficiency

With 22.7% efficiency, the 635W module converts a substantial portion of the sunlight reaching its surface into electrical power under standard test conditions. This efficiency is useful when planning a solar array for a limited roof area. However, the final system size also depends on module dimensions, spacing and site constraints.

Temperature Performance

The power temperature coefficient is -0.29%/°C. Solar module output generally decreases as cell temperature rises above the standard test temperature. Therefore, proper ventilation and mounting clearance can help manage operating temperatures.

Dual-Glass Construction

The panel has 2.0 mm front glass and 2.0 mm rear glass, supported by a silver anodized aluminium frame. This construction is relevant to buyers considering bifacial modules for commercial and ground-mounted applications.

Best Applications for Astronergy 635W Bifacial Solar Panels

The Astronergy 635W Bifacial Solar Panel is worth considering for:

• Commercial solar installations requiring high-output modules.
• Industrial solar systems with suitable inverter and mounting arrangements.
• Ground-mounted solar projects designed to use rear-side generation.
• Large rooftops where module dimensions and electrical limits are suitable.
• Solar installers and project developers evaluating N-type TOPCon bifacial modules.
• Projects where long-term power warranty coverage is an important purchasing consideration.

When the Astronergy 635W Bifacial Panel May Not Be Suitable

Consider another module if the installation has insufficient space for this panel’s dimensions or if the inverter cannot accommodate its electrical characteristics. Similarly, a bifacial design may provide limited additional benefit when the mounting arrangement prevents useful rear-side illumination.

Therefore, the correct panel should be selected according to the complete system design rather than wattage alone.

Astronergy 635W Solar Panel Technology and Cell Design

The Astronergy 635W Bifacial Solar Panel uses N-type monocrystalline cells with TOPCon 4.0 technology. Its bifacial design enables generation from both surfaces, while the dual-glass construction encloses the cells between front and rear glass layers.

The module contains 156 cells arranged in a 6 × 26 configuration. However, its electrical output must also be considered alongside the inverter’s maximum DC voltage, MPPT operating range and current limits. Installers should account for the rise in open-circuit voltage at low temperatures when calculating string length.

Astronergy 635W Bifacial Solar Panel Specifications

The following table summarises the key electrical, mechanical and warranty specifications of the Astronergy 635W Bifacial Solar Panel.

Astronergy 635W Solar Panel Performance and Degradation

The panel has a first-year power degradation limit of 1.0% and a maximum annual degradation of 0.4% from year 2 through year 30. Under the applicable linear power warranty terms, its stated power output at year 30 is 87.40% of the original rated power.

These figures describe the warranted power-performance schedule. However, they do not guarantee the actual energy a solar system will generate each day or year. Actual output depends on sunlight, temperature, dust, shading, system losses, maintenance and installation quality.

Astronergy 635W Bifacial Solar Panel Power Gain

The panel’s integrated-power figures illustrate potential output under different rear-side power-gain assumptions.

These figures are illustrative calculations under specified rear-side power-gain conditions. They are not the panel’s standard 635W front-side rating. Furthermore, actual bifacial gain depends on the installation environment. Therefore, installers should not assume these figures when sizing the inverter or estimating guaranteed system output.

Astronergy 635W Solar Panel Performance in Pakistan

Pakistan’s summer conditions make temperature management, ventilation and regular panel cleaning important parts of solar system design. Dust and other deposits can reduce the sunlight reaching the cells. Therefore, cleaning should follow the installation and safety guidance applicable to the site.

For bifacial installations, rear-side clearance and the surface beneath the panels can influence additional generation. In addition, installers should consider mounting height, row spacing, shading and ground reflectivity during project planning.

The panel’s 1500V DC maximum system voltage is a module limit, not a recommendation to operate every system at that voltage. Installers must calculate string voltage under the lowest expected site temperature. They must also ensure that the inverter, cables, connectors and protective devices remain within their permitted ratings.

Astronergy 635W Solar Panel Price in Pakistan

Buyers searching for astronergy 635w solar panel price in pakistan or astronergy 635w bifacial solar panel price in pakistan should also consider module specifications, warranty coverage, installation requirements and inverter compatibility. Furthermore, prices and availability can change. Therefore, confirm the current offer and required quantity with Hajvery Solar Energy before ordering.

Installers, commercial buyers and dealers can contact Hajvery Solar Energy in Johar Town, Lahore, for product enquiries and quantity-based pricing.

Astronergy Solar Panel Grade and Authenticity Verification

When evaluating Astronergy solar panels, buyers should distinguish brand reputation from the verified condition and authenticity of the actual module being purchased. A brand-level classification does not independently establish the grade, condition or warranty eligibility of every individual panel.

For astronergy solar panels verification online, confirm the exact model and serial information through the manufacturer’s available verification channel, where provided. In addition, keep the purchase documentation and applicable warranty information for future reference.

Hajvery Solar Product Verification

Before purchasing the Astronergy 635W Bifacial Solar Panel, confirm the exact model, module condition, serial information and applicable warranty coverage. Also, ask the installer to check the panel’s electrical specifications against the selected inverter and proposed string configuration.

Hajvery Solar Energy can assist buyers with product enquiries and installation-compatibility considerations. However, physical stock and availability should be confirmed before placing an order.
