Solar Cells and Modules

The modules are made with various mixtures of cells, that leads to different looks, power outputs per module, and busbar arrangement on the modules that carry the generated solar current.

Each module piece will carry the capacity details obtained under standard testing conditions The shape, size, wattage class may vary according to the raw material availability

Panel

Cables

The cross-sectional view below shows the various layers of the cable outer covering and the inner cores. On the DC side generally 4 sq. mm thick cables are used and on the AC side, it depends on the inverter distribution, distance to the LT panel, etc.

Cable Tray & Accessories

Cable Tray accessories guide the cables in an ordered and safe manner. They give mechanical support for support to cables and protect them from various conditions such as mechanical stress, moisture, fire, UV exposure etc. Cable trays will be fabricated using high quality Hot Dip Galvanized iron material or FRP as per the design decision of Becquer with suitable thickness and sizes.

Standard Features:

• High quality HDG trays with minimum of 80 Microns thick | Fibre Glass Reinforced Plastic substrate.
• All standard sizes were available.
• Most ergonomic design for ease of installation.
• Direct plug-in type approach.
• Effective Heat transfer process.
• All fitting accessories are of SS 304 rust free material.
• Channels available in 2.5 – 3 meter long for better transportation and handling.
• Channels can be mounted on galvalume sheets, RCC ceilings, Side walls etc.
• Standard thickness available in 1.6 mm, 2 mm, 2.5 mm, 3 mm.

Cable conduits

In addition to Cable trays, cable conduits were used to route the cable where cable tray laying is not possible such as on top of RCC roofs, narrow underground tunnels etc. The cable conduits are available in both rigid & flexible units as demanded by the application.

Standard Features:

• Heavy duty PVC conduits for internal applications.
• HDPE conduits for external applications due provide protection against UV rays from exposure to direct sunlight.
• End cap sealing arrangement to avoid water clogging.
• Threaded mouth design for quick & efficient installation.
• Suitable “L” & “T” Bends for required turns without additional mechanical stress on cables.

Cable Lugs – Terminating Accessories

Lugs are constructed from high-quality materials made with electrolytic copper for high conductivity and tin-plated for corrosion resistance. The Lugs are designed, manufactured, tested and comply with International Standards like BS, DIN, UL and IEC.

Inverter

Power Conditioning Unit – Fuse Less Inverters

Inverters are power electronic converters which convert DC power generated from Solar Arrays into standard 3 Phase or 1 phase AC power to synchronize with Power grid for safe operation. All inverters are up to date upgraded with latest technology for increased conversion efficiency & other salient features.

The diagram below shows the internal architecture of the inverter:

The following 4 features are a must for all inverters or power conditioning units

Based on the roof specific factors, the stringing of the DC cables, that is designing the current flow from the solar modules to the inverter in the most optimized way is done using the below 3 architectures. The overall objective is to reduce the current losses, minimize the heat loss due to current and maintain balancing amongst the current flows between inverters.

Architectural Options:

Accessories

To attach the components together in a seamless and secure way multiple accessories are needed as listed below. During the assembly work, the Becquer team may add more components at its discretion.

RMU

The entire solar plant would be digitalized for its power flow and all key geographical and electrical parameters would be tracked on a continuous basis for 25 years in the following architecture. The night light would be installed for safe and emergency access.

All the data would be accessible to the end customer for all the days, with an easy toggling on the online platform that would allow for any historical data to be accessed at the click of a button.

Others

Metering architecture – Energy recording & monitoring

The Energy generation from the Solar Power plant must be monitored accurately to quantify & assess performance of plant on timely basis. Becquer chooses state of Art metering infrastructure in terms of smart meters with high accuracy class as per requirements. Various meters for energy include ETV based uni directional , Bi-directional meters, Dual source meters, ABT based meters, Digital multifunctional meters etc. All meters are equipped with RS485 communication module for remote monitoring using SCADA systems.
