The panel contains a number of items including:

  • The inverter(s) which convert from (DC) direct current to grid synchronised AC(alternate current)
  • Safety fuses and isolator switches, for the input from the PV panels, and output to the grid
  • Various meter’s for measuring the energy generated by the system, the voltage and current coming from the PV system

Types Of Solar Panels And PV

PV Cel Type for Solar

 

  1. Crystalline Silicon (C-Si) For PV Technology

 The crystalline silicon is a widely used crystalline form of silicon to manufacture solar panels made from crystalline (mono and polycrystalline PV) in the photovoltaic technology. Silicon used in solar panels made from crystalline are mostly used almost 90 percent. The primary factor that makes it most used is its purity which gives more ability to the solar panels for conversion of sunlight into electricity.Here is more info on it.

  1. String Ribbon Solar Cells

 In this process, crystalline silicon foils and strips are manufactured for PV or photovoltaic technology. Wires that are resistant to high temperature are used to form thin ribbon crystalline silicon crystals by pulling them through molten silicon. These thin ribbons are then cut in various lengths to form solar and PV cells. These string ribbon solar cells are also made from polycrystalline silicon. Check educational resource here.

  1. Amorphous Silicon Solar And PV Cells

It is a subcategory of thin silicon film solar cells and is recently becoming very popular everywhere. These amorphous silicon PV modules use very less silicon around 1 percent in the crystalline solar cells. These are also very efficient than mono or polycrystalline solar panels or PV modules.Read more here.

  1. Thin Film Solar Cells (TFPV) Or (TFSC)

These are also called TFPV or thin film photovoltaic cells and too amorphous PV modules. The necessary process to make them is integrating thin layers of PV materials may be one or even more on a substrate like metal, plastic, glass, etc. It is a second generation PV cell. The thickness of these thin films can vary from nanometers to micrometers.

  1. Cadmium Telluride Solar Cells (Cdte)

This type of solar cell is based on the element Cadmium Telluride. These are the only solar or photovoltaic technology that is very cost effective in comparison to crystalline silicon solar panels especially in the multi-kilowatt system of the market.

CDTE Cell

The efficiency ranges of these PV modules are between 9 percent to 11 percent.

  1. Building Integrated Solar Panels Or Photovoltaic Panels (BIPV)

They are not something very new but same as silicon crystalline or thin film solar panels. They are just made in the shape and design of the roof tiles. BIPV or building integrated photovoltaic panels are designed in a way to let them be part of the building like roofs, walls, windows, facades and other things which can fit solar cell materials. The best example of building integrated photovoltaic panels is solar shingles which look very beautiful and charming but are a little expensive.
