BIPV and facade-mounted solar power systems

BIPV systems (Building-integrated photovoltaics) are solar power plants that are integrated into buildings and structures. Such systems, in addition to their direct purpose – the generation of electricity, also perform the functions of structural elements of the building, complementing or completely replacing traditional building materials (facade and roof structures). In the coming years, BIPV solutions will be most actively developed in comparison with other types of solar power plants.

Avenston is engaged in the design and construction of solar power plants that are built directly into the structure of a building or structure. Integrated into buildings BIPV systems are usually installed on flat and pitched roofs, embedded in facades or glazing elements. Also, this technology is used in the construction of solar canopies and other auxiliary structures and elements of urban infrastructure.

According to the location and features of the mount, there are the following four main types of BIPV systems:

  • Crystalline silicon solar modules;
  • Thin-film solar modules made of amorphous-crystalline silicon;
  • Thin-film solar modules based on CIGS (copper, indium, gallium, selenide) on flexible modules;
  • Double glass solar modules “glass-glass” with square silicon elements inside.

Today, among BIPV-systems, the most efficient are «glass-glass» crystalline and thin-film solar PV modules.

The main goal of BIPV is the ratio of clean electricity efficiency of the building with the architecture of the city as a whole. That is why much attention is paid to aesthetic solutions of new building materials. Of course, if you compare standard solar modules with BIPV, the efficiency is lower. However, if we take into account the architectural component, the BIPV system remains in a winning position.

Thin-film solar modules made of amorphous and crystalline silicon cope well with a variety of shapes and shades. Variants of their shades can be seen in the image.

When designing BIPV systems, it is necessary to find a balance between optimal conditions for generating solar power and the structural features of the building, complying with the requirements of state building codes and regulations. Thanks to their properties, solar BIPV modules are able to effectively replace traditional building materials, providing additional value in the form of clean and cheap electricity generation. The constructive variety of BIPV systems allows them to be used as an element of architectural design, complementing the positive image of the building, and also to create a comfortable environment inside buildings due to excellent thermal control, soundproofing and protective properties.

Benefits of BIPV systems

Modern solar energy technologies have a number of indisputable advantages that make it possible to increasingly implement engineering solutions based on them in new projects. Solar power plants, which are deeply integrated into the design of buildings and structures, have the following advantages:

  • reduced losses of electricity due to the maximum proximity of the generation source to the consumer;
  • savings on capital costs during construction by replacing traditional building materials with BIPV panels;
  • excellent thermal insulation properties, which can significantly reduce the cost of ventilation and air conditioning;
  • aesthetic characteristics and visual appeal of BIPV solutions and many others.

Avenston’s key services for BIPV solar power plants

Our company is a general contractor in the construction of facade solar power plants and photovoltaic systems integrated into buildings (BIPV). Installation of BIPV systems is relatively new direction, therefore it will demand builders’ training to level up their skills. Avenston company is ready to provide professional education, consultations and services both on planning stage of a residential house or an office building, as well as directly during building and installation works. Our specialists will provide correct from architectural point of view installation of BIPV systems and their specialized connection both to electrical system of a house and to general electric system.

Despite the higher initial cost of facade-mounted PV system and BIPV systems, the introduction of such solutions can reduce the total cost of civil works and materials at building construction. Thus, when implementing BIPV systems, it is necessary to pay attention not only to the unit cost of installed kW of solar modules, but also to economic feasibility of the whole project. The cost of both the equipment and the work itself, and the cost of the generated electricity, as well as the amount of money saved during construction, for example, on roofing materials or facade cladding, must be taken into account. That is why projects for the implementation of facade PV and BIPV systems require not only high technical qualifications of the contractor, but also deep economic knowledge.

Avenston offers its customers full support for projects for the construction of solar power plants integrated into buildings. We will help you calculate the economic feasibility of such a project, select the most optimal technical solution, develop design documentation and install your solar PV power station. General contracting services include the full comprehensive support of your project for the installation of facade photovoltaic systems or BIPV systems.
