Prefabrication of roof integrated PV systems

Objective



One of the main barriers that impede large scale application of PV in buildings is that the realisation of high-tech building integrated PV (BIPV) systems is poorly tuned to the regular on-site low-tech building process and therefore too time consuming and expensive.
PRIDE aims at the improved integration of PV in the regular building process through joint industrial prefab PV roof development by building industry, PV industry and utility sector, being the logical next step, now that the advantages of building integration have been proved and have appointed a key role to the, building sector. PRIDE will lead to cost reduction, quality improvement and enhanced market acceptance of BIPV, by builders and utilities. First experiments in the Netherlands, show that industrial prefabrication is technically feasible and has a good cost and time reduction potential. In addition the concept is very promising as a result of the fact that there is a general trend towards industrial prefabrication in the building industry. The following innovative aspects can be mentioned:
. Strong collaboration between PV industry and building industry; . Precabling and premounting of PV systems prior to installation on the building site;
. Use of industrial prefabrication technology for BIPV;
The activities of PRIDE will start withthe definition of a program of requirements based on the knowledge and experience of the project partners and additional information on state-of-the-art and future developments in industrial prefabrication.
With the programme of requirements, a number designs will be developed both for southern and northern European climates and optimised with respect to price/performance ratio.
The selected designs will be prototyped and tested on constructional, building physical and electrotechnical properties. During the last phase the development of the prefab PV roof element will be evaluated and strategic R,D&D priorities will be described.
Expected achievements are:
1. 50 % reduction of BOS costs, mainly by cutting down on-site installation;
2. Full integration of PV in the building process, leading to better applicability and improved market acceptance of PV technology by the building sector throughout Europe;
3. Improved quality of BIPV through the transfer of the high-tech PV installation activities from the low-tech building site to industrial production sites;
4. Improved architectural and aesthetic quality of BIPV through the integrated design.
It is foreseen that the project will be followed by the realisation of pilot projects and subsequent marketing of the PV roof concept as designed by the PRIDE consortium
PRIDE partners are Ecofys, VELUX, RWE, UNIDEK, Institut fur
Industrialisierung des Bauens, R&S Renewable Energy Systems and ENEL.
