Theoretical analysis of the blinds integrated photovoltaic modules

The ventilation's affect on the temperature decrease of photovoltaic modules in a double-layer window façade was analyzed using a heat exchange network analysis between layers of the photovoltaic module integrated blind (PV-blind). The temperature of the components in a PV-blind and the amounts of harvested energy are calculated with an hourly time step during one sunny day. The maximum temperature of a photovoltaic module without ventilation is almost 78 °C, which means a daily electric energy production rate decrease from 14.1% to 10.4% compared to temperature independent case studies. Blinds with a ventilated façade for buoyancy driven airflow provide a maximum photovoltaic temperature of 58.4 °C and have a greater efficiency at 11.7%.
