Distributed PV Power Station Systems

0 Browse

Distributed Solar/Photovoltaic Power Stations are grid-connected solar/power generation systems designed based on the actual conditions of household or commercial users’ roof loads and electricity consumption. This system converts solar energy into direct current (DC) electricity through solar modules, without storing the electricity in batteries. The DC electricity is then directly converted into alternating current (AC) electricity via a grid-connected inverter and fed into the standard grid, relying on the grid for operation.

The system can be remotely monitored through various methods. The monitoring includes the following: system operating status, real-time power, daily electricity generation, total electricity generation, warning messages, revenue calculation, energy-saving and emission reduction data, environmental benefits, and more.

The system operates on a self-consumption model with surplus electricity fed back into the grid. It allows for nearby consumption of electricity, effectively utilizing idle rooftop space. With a one-time investment, users can benefit for 25 years. Any unused electricity generated by the system can be sold back to the grid and users can enjoy government subsidies. It is a stylish, eco-friendly, and energy-saving solution.

Solar modules

The solar module is composed of high-efficiency crystalline silicon solar cells, ultra-white textured tempered glass, EVA, transparent TPT backsheet, and an aluminum alloy frame. It features a long service life and strong mechanical resistance to external pressure.
The solar module is the core component of a solar power generation system and also the most expensive part of the system. Its function is to convert solar radiation energy into direct current (DC) electricity.

Junction Box

To reduce the connections between the solar modules and the grid-connected inverter, and in cases where the inverter input terminal is insufficient, a junction box is used for centralized connection and integration.

Grid-connected Inverter

The grid-connected inverter converts the DC electricity provided by the solar modules into AC electricity that is in phase and frequency with the utility grid. It is the core conversion component of a photovoltaic grid-connected power generation system. Grid-connected inverters are mainly divided into two types: string inverters and central inverters.

AC Distribution Cabinet

The AC distribution cabinet centralizes the AC output terminals of multiple grid-connected inverters for unified output, facilitating the cable connection between the inverters and the grid metering cabinet. It also features functions such as lightning protection, distribution, and monitoring.

Step-up Transformer

The step-up transformer increases the voltage from 400V to 10kV or higher, facilitating long-distance transmission and power delivery.

Principle of Solar Photovoltaic Power Generation Technology

Based on the photovoltaic effect, the system is primarily composed of three main components: solar panels, grid-connected inverters, and a control system.
Stable and reliable, with a long lifespan and easy installation and maintenance, as shown in the diagram.

Comparison of Different Types of Solar Panels

Solar/Photovoltaic on Color Steel Roofing

Also known as color-coated profiled roofing, the coated steel plate is cold-rolled and bent into various wave profiles. It is now widely used in industrial construction. The components can be laid parallel to the roof slope, or designed for installation at a fixed tilt angle. Common installation methods include: standing seam type, angle ridge type, clip-on type, and exposed fastener type.

Solar/Photovoltaic on Concrete Roofing

Utilizing the density of reinforced concrete roof panels, the roof is waterproofed by treating the panel surface and seams. The mounting brackets are connected to the existing roof. There are four common installation methods: concrete pedestal ballast method, prefabricated concrete block method, post-anchor chemical bonding method, and structural adhesive method.

Solar/Photovoltaic Carport

A power generation system that directly converts solar energy into electricity using solar cells. Its features include high reliability, long lifespan, no environmental pollution, and the ability to operate independently or connect to the grid. Compared to adding components on top of the carport roof, it also saves costs.

Elevated (BIPV Waterproof Type)

The concept of generating energy for buildings integrates solar/photovoltaic technology fully with the structure, offering the advantages of aesthetics, practicality, and cost-effectiveness. It has become a mainstream technology for low-carbon buildings and energy-saving solutions. It is mainly applied to the renovation of old building roofs, new buildings, agricultural and livestock facilities, carports, and municipal transportation facilities that require insulation and waterproofing.

Customized

We provide one-stop services across all stages, including initial consultation, solution design, engineering installation, grid connection support, monitoring and maintenance, system upgrades, and loan application, making solar power generation simpler.

Service Model

EPC Model

Entrusted by the client, the contractor undertakes the design, procurement, construction, and trial operation of the project, either for the entire process or certain stages, according to the contract. Under a lump-sum contract, the contractor is responsible for the quality, safety, cost, and construction progress of the contracted work.

BT Model

Construction Transfer is an investment construction model adopted in the development of basic infrastructure projects. According to the contract signed between the project initiator and the investors, the project is financed and constructed, and upon completion, the project is transferred to the initiator within the stipulated timeframe. The initiator then repays the project investment and agreed-upon returns to the investors in installments, as per the pre-established repurchase agreement.

EMC Model

Energy Contract Management Model: The client provides the factory roof, while we invest, construct, and operate the system. The energy savings benefits are shared, and the client enjoys a discount on the electricity generated by the power station. After the sharing period ends, the constructed power station is transferred to the client free of charge, and the ownership of the power station is fully transferred to the client.

Engineering Installation

Based on the actual conditions of the client’s roof, we provide tailor-made, efficient installation solutions. With rigorous control and high-quality hardware, we build a high-performance power generation system.

Grid Connection

We handle the grid connection application on behalf of the client, confirm the connection plan, and conduct acceptance and commissioning after the project approval and installation are completed.

Custodian Operations and Maintenance (O&M)

The customer service team will respond to every client need and rigorously manage the system, ensuring that all project-specific information and original records are always accessible.

  • With a dedicated and experienced team, we provide reliable and expert solutions.
  • We provide scientific surveying and design to ensure optimal sunlight coverage for maximum efficiency.
