Theintegrated photovoltaicit seems to represent a sector in itself as its needs differ from those of the classicphotovoltaic. If to create a solar park you aim for maximum cell efficiency, to develop a model ofintegrated photovoltaicit is necessary to take care of the aesthetic aspect, the choice of materials, the architectural context of insertion and many other parameters that cannot be separated from the same efficiency.
Forintegrated photovoltaicwe mean the architectural implementation of solar cells as roofing of buildings thanks to particular technologies. The photo above shows an example of integrated photovoltaic, in particular it is the largest plant architecturally integrated photovoltaic of the world.
The integration occupies the entire facade of the company buildingsSuntech Power, a leader - by chance! - in the production of photovoltaic modules. There photovoltaic facade it covers an area of 6,900 m2 and produces a total of 1 MWp.
We Italians are certainly not poor in language but also this time the English language prevails: theintegrated photovoltaic takes the name ofBIPV, acronym forBuilding Integrated PhotoVoltaics, orArchitecturally photovoltaic systems integrated.
L'architectural integrationit is obtained by placing the photovoltaic field of the system within the profile of a building that houses it.
Given the complexity of the industry, the costs associated with theintegrated photovoltaicthey are far superior to what has been seen for setting up a typical solar roof.
As well as the costs, the results also differ greatly starting from the aesthetics which are much more valuable.
Implants withintegrated photovoltaicthey often manage to resolve by bypassing the request for photovoltaic clearance necessary to continue with the installation of systems in particularly prestigious locations.
The techniques to obtain thephotovoltaic integrationthere are mainly three:
- Local replacement of the roof covering with a suitable coating on which the photovoltaic module is superimposed. In this context we mention products such as iphotovoltaic coatings,walkable solar tiles or the same ones photovoltaic tiles,latest generation building materials, able to incorporate photovoltaic technology directly into the roof covering.
- Use of detailsphotovoltaic technologiesthat allow integration. This is the case ofthin filmsthat allow the production of solar energy with a very thin photovoltaic field.
- Use of structural photovoltaic modules, or materials that in addition to carrying out the function of energy production are also able to perform a structural function. In this context, we mention particular fixtures and materials such as the very Italian photovoltaic glass brick.
For theintegrated photovoltaic, the oldEnergy billprovided for a higher incentive rate for those who decided to adopt this technology. To learn more, the article dedicated toDO, Italian acronym forArchitecturally integrated photovoltaic.
