What is Solar Panel?

A solar panel is a device that converts sunlight into electrical energy.
Solar panels are also commonly referred to as panel surya, solar modules, PV, etc.

Basic Structure of Solar Panel

Solar Panel
1

Solar Glass

The glass used for solar panels has the ability to block sunlight from being reflected and can be processed to generate electricity.

The glass also functions as tempered glass, capable of withstanding >5400N/m² from a cross-sectional direction, and of course, protects the module from water, dirt, etc.
2

Cell

Cells are semiconductors that convert solar energy into electrical energy.

Due to their susceptible corrosion, we always maintain stable air temperatures during material storage and adhere to specific standards during the production process.
3

Eva

This is the part of the solar panel that serves to bond the glass, cell, and backsheet during the laminating process.

We store this material at a stable temperature of 25°C and 40% humidity. It should not be exposed to sweat or alcohol, and it should not be left in open spaces for extended periods.
4

Back Sheet

The part of the solar panel that functions as a protector from the rear, and prevents water from entering the module.
5

Aluminium Frame

The part that protects the solar panel from impacts coming from the side/edge of the solar module.

Junction Box

A junction box is a protective enclosure designed to contain electrical connections from solar panel to external cable, while shielding them from dust, moisture, and mechanical damage. It provides a secure space for wiring, preventing accidental contact with live wires, reducing the risk of short circuits, fire hazards, and electrical shocks. Junction boxes also help organize wiring, making maintenance, and inspection.

Kinds

Monocrystalline Sim-50

Monocrystalline

Monocrystalline cells are produced from a single silicon crystal, resulting in a uniform structure. This uniformity gives the cells a consistent appearance, typically black or dark in color. The black surface absorbs nearly the entire light spectrum, thereby maximizing photon capture and leading to higher conversion efficiency.
Polycrystalline

Polycrystalline

The Cells produced from multiple silicon crystals are fused together, which is why they are called polycrystalline. Because of the multiple crystals, the resulting color varies, often appearing metallic blue or patterned. Compared to monocrystalline, this type has nearly the same efficiency


The efficiency of solar panels, whether monocrystalline or polycrystalline, is influenced not only by the cell type but also by several external factors. These include the application of anti‑reflective coatings, the precision of the production process, the geographical location, and the installation method. Together, these variables determine the overall performance and energy conversion capability of the panels.

System

Photovoltaic System
Solar power generation systems can be broadly divided into two types: On Grid System and Off Grid System.
Monocrystalline Sim-50

OFF GRID SYSTEM

It is a system that consumes the generated electricity within the system. Because it is not connected to commercial electricity, it is called an "independent power supply system" or called commonly " Off grid system". However, the electricity generated from solar panels depends on the intensity of sunlight. For this reason, many independent power supply systems store the generated power in a battery (storage battery) and discharge it from the battery as needed.
Polycrystalline

ON GRID SYSTEM

The power generation system is connected to commercial electricity, and the electricity generated by solar panels is consumed by itself, and if there is a shortage of electricity, electricity is purchased from the power company. On the other hand, if there is a surplus of electricity, the electricity will be sold to electric power companies.

Application

Solar panels are presently employed in a diverse range of applications. The following example, drawn from their implementation at PT Sky Indonesia, may serve as a valuable reference.
