Glass-glass PV modules are a more sophisticated production process, and therefore more expensive than a standard glass-tedlar PV modules (see chapter 4). These are not suitable for the replacing alternative construction products and extra costs apply for the support structure. These costs are already included if the PV module are being fixed within curtain wall units. The installation cost between a BIPV (calculated according chapter 11) and a conventional roof panel PV system will therefore not be greatly different. As indicated previously in chapter 11, the real value of a BIPV installation is not always easy to quantify (aesthetics, image,…). The comparison between BIPV and conventional installations or modules is not really valid.
