6.3.2 PV Module

Appearance

Figure 6-12 shows a PV module.

Figure 6-12 PV module

Functions

A PV module, as an important component for light-to-electricity conversion in the Solar

Power System, supplies power to loads. It is resistant to corrosion, wind, and rain. PV

modules are connected in series or parallel to meet load voltage and current requirements.

Features

A PV module has the following features:

Good light transmission.

Double-layer solar cell, with high circuit reliability.

Long service life (25 years).

Multi-layer polyolefin compressed circuit, which is moisture-proof, well-insulated

and works stably under undervoltage conditions.

Certified by the TUV, Underwriters Laboratory (UL), International Organization for

Standardization (ISO), CE, and International Electrotechnical Commission (IEC).

6.3.3 PV Module Support

Appearance

A PV module holds one or more PV modules in position. PV module supports are classified

into standard supports, scalable low supports, and scalable high supports. Their appearance is

shown in Table 6-7.

Table 6-7 PV module support appearance and features

Support Type

Appearance Feature

PV module

support

It supports Huawei PV modules and

SJBs.

Three PV modules form one basic

unit.

The PV modules installed on the

support all have a 25-degree

angle with the floor. The angle

cannot be adjusted.

Customer equipment can be installed

under the PV modules. The upper

edge of the PV modules is 3300 mm

above the floor, and the lower edge is

2000 m above the floor.

6.3.4 SJB

Appearance

Figure 6-13 shows an SJB.

26

Functions

An SJB allows outdoor PV arrays to be connected in parallel and provides surge protection

for PV modules. It consists of input and output wiring terminals, a protection device for PV

module inputs and outputs, an SPD, and a ground bar. To decrease cable voltage drop and

facilitate installation, multiple SJBs can be used based on site requirements.

6.4 ESS

Appearance

Figure 6-14 shows a storage unit.

Figure 6-14 Storage unit

Features
