The placement, orientation, and inclination of the surfaces are tested in Ladybug in order to get the best performance and still keep the desired design proposal. Considering the extreme climate of the site and with plenty diffused light with few direct sun exposure, it was important to choose high efficient PVs that could be most effective for the given conditions. The chosen type for the PV installation is X-Series solar panels from manufacturer Sun Power with average panel efficiency of 21% and nominal power 335 W. The chosen module has a system that is proven to hold efficiency much better in low-light conditions with high-quality anti-reflective glass that traps incoming light from all angles. (Sunpower.com, 2017) The PVs are mounted on the inclined (60°) wall surfaces on the Sun facing facades.
The total designed area of PV cells on the building A is around 100 m2 which is twice as much the need for covering both building related and user related energy use. Since the other buildings have smaller PV capacity, the excess energy from the building A would be distributed according to needs. The production is sufficient for 44 kWh/ m2 (Appendix A), and the calculation for the required area of the PVs is listed in Appendix D. Total electricity production from the PVs of the building A is 9.347kW per year.
