Harvesting of Photon Energy through PV on Building Envelope and Windows Canopy

It often does not occur to us that there is a space or point in the construction of a house or residence that has the potential to develop new and renewable energy sources (EBT) that produce additional electrical energy. The position of the window canopies and building walls has the potential to place solar panels (PV) according to the canopy design without requiring additional installation costs. This position is known as passive energy. The advantage is that it is easier to maintain compared to PV panels installed on the roof of the house. Although this position is not optimal to get sunlight, at least there will be photon energy captured by placing PV in the path of the sun’s shadow. This means that the solar thermal value that PV does not like will decrease, while what is needed for PV semiconductors is photon light. Therefore, this study aims to increase profits in terms of construction management of exterior walls and building canopies, especially window roofs. The observation results show that The position of placing the PV panels in one direction of the sun’s shadow, which is on the west side of the building gives better advantages to PV on the building envelope compare with window canopy. The PV output power generated on the building envelope is about 6 Watt, while the window canopies are only around 4 Watt. Need further investigation on different site of the building.
