Overall evaluation for R and D of PV modules integrated with construction materials

To encourage the use of photovoltaic power generation, the power generation costs must be reduced to the same level as those of power purchased from electricity utilities. This can be done by significantly reducing the initial costs of the PV systems. In such systems, excluding the PV modules, the support frames and the installation work account for the majority of the costs. Therefore, PV modules integrated with roofing or wall materials is expected to be one of the most effective ways to reduce the costs of the systems.
