The integration of Building Applied Photovoltaics (BAPV) and Building Integrated Photovoltaics (BIPV) in new and refurbished buildings are gaining more and more traction, but how much is needed to offset your buildings energy consumption. We have developed a PV calculator, which allows you to estimate the possible energy generation from your roofs and facades by area.
SIMPLE DAYLIGHT FACTOR CALCULATOR
Kuala Lumpur has imposed a mandatory requirement for all new and future residential & commercial developments to implement at least 30% of renewable energy (RE) produced on-site. Documents show that system design and calculations shall be submitted at Development Order (DO). The below calculator can be used to give an initial estimate of the roof and/or facade areas needed for your project to achieve the 30% requirement.
Please note that the above simplified PV calculator is based on fixed values for solar panel density (8m2/kWp) and annual solar electricity yield of Kuala Lumpur (1,200kWh/kWp). For custom calculations for other locations please use the detailed PV calculator below or contact us at email@example.com for an in-depth PV study of your project.

Detailed PV CALCULATOR
Use the calculator below to estimate the required PV area at different locations in order to meet your renewable energy production target. Investigate how your building roof and facade areas can contribute.
SOLAR IRRADIATION STUDY
The solar irradiation for different sites can be found in databases as shown below from the Global Colar Atlas. However, it becomes slightly more complex when taking into account the actual location of the PV panels and how these might be shaded from the surroundings.
We can help you to determine how your building or development will be shaded throughout the year and how this will affect the annual yield for PV panels and different roof and facade locations. Information, which is valuable for deciding the optimal location and size of the PV installation. We use 3D models reflecting the actual architectural design and annual hourly radiation data for a more precise and realistic result, as exemplified in the video below.
