Abstract

Photovoltaic (PV) installation potential on residential building envelope in equatorial region was analysed by 3D insolation colour rendering employing BIM Revit solar analysis tool. Monthly global solar radiation calculation was employed to investigate solar potential in study case area. Actual energy consumption of residential sector was used as a base to predict energy demand for next 10 years. Predicted energy demand was then used to calculate the area needed for photovoltaic installation to balance future energy demand. The energy consumption by residential building was divided into five different installed electrical power capacities namely 450 Watt, 900 Watt, 1300 Watt, 2200 Watt and 3500-6600 Watt. Study results suggest that the potential location of photovoltaic panel installation on detached houses is on the roof, East, and West walls. Abundant solar energy in equatorial region was proved by high potential of PV energy generation 7 – 9 kW/m² for amorphous silicon, 17 – 18 kW/m² for polycrystalline silicon, and 19 – 23 kW/m² for monocrystalline silicon. The roof element alone can provide sufficient electrical energy generated by installed photovoltaic panels for the next 10 years. The area needed to supply 450W – 6600W installed power capacity were 13 – 75 m² for monocrystalline silicon, 23 – 120 m² for polycrystalline silicon, and 50 – 259 m² for amorphous silicon. To conclude, implementation of photovoltaic installations on residential buildings have a huge potential to secure not only recent energy consumption, but also future energy demand.
