Abstract: A method, apparatus and user interface for component placement for components of a system including a solar energy generation system, an energy storage system or both. The method receives indicium of a location for installation of the system, receives indicium of energy requirements for the facility at the location, and retrieves at least one image comprising one or more of a roof view of the facility, a digital surface map containing the facility or an irradiance map of the facility. Based, at least in part, on one or more of the digital surface map or the irradiance map, determining locations for placement of components of the system, and rendering an image of the facility including the components positioned at the determined locations.
