Technology of installing photovoltaic panels

How does a photovoltaic system work?

The heart of a photovoltaic system is the solar module. Many photovoltaic cells are wired together by the manufacturer to produce a solar module. When installed at a site, solar modules are wired together in series to form strings. Strings of modules are connected in parallel to form an array.

What is building integrated photovoltaic (BIPV)?

One application starting to become widely popular worldwide is the Building-Integrated Photovoltaic (BIPV) highly dependent on thin-film solar technology. There are two main branches of this technology, solar shingles or solar roof tiles, and solar windows or solar glass.

What is the IEA photovoltaic power systems technology collaboration programme?

The IEA Photovoltaic Power Systems Technology Collaboration Programme, which advocates for solar PV energy as a cornerstone of the transition to sustainable energy systems. It conducts various collaborative projects relevant to solar PV technologies and systems to reduce costs, analyse barriers and raise awareness of PV electricity’s potential.

Where do solar PV modules come from?

In 2017 the Asia-Pacific region dominated the market for solar modules, accounting for the majority of the solar PV modules installed globally (76%). This is followed by the Americas and Europe with a share of 14% and 9.5%, respectively.

Should a general contractor install a solar PV system?

A general contractor may face a choice between using an electrical subcontractor or a solar subcontractor to install the PV system. A good solar contractor will have the expertise in solar PV systems plus qualified electricians on staff.

How do photovoltaic modules work?

Photovoltaic modules consist of a large number of solar cells and use light energy (photons) from the Sun to generate electricity through the photovoltaic effect. Most modules use wafer -based crystalline silicon cells or thin-film cells.
