How efficient is a photovoltaic system?

Today, the efficiency of a photovoltaic system is about 24%: that means that the technology allows a quarter of the solar energy received by the modules to be transformed into electricity. Find out how a solar park is built, from the construction phase to energy production, and how a photovoltaic system operates.

What is the construction and installation phase of a solar project?

With permits and financing secured, the construction and installation phase of a solar project can commence. This phase is where the physical solar panels and equipment are installed on-site and connected to the power grid. It includes several key steps that require careful planning and execution.

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 a photovoltaic module?

Photovoltaic modules: devices made up of a mosaic of interconnected photovoltaic cells. These cells are the most basic element of a photovoltaic system: they directly convert solar energy into electrical current thanks to a phenomenon called the photovoltaic effect;

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 are solar panels installed?

Solar panel installation requires careful planning and execution to ensure they are installed safely and effectively. The numerous mounting systems will be installed on the ground or on a roof, depending on the design of the solar project.
