                          10.2.1 Module mounting approaches
                          For household systems, modules can be mounted on array frames next to the house, in
                          a position where no shading from buildings or trees would occur. However, in many
                          cases, rooftop mounting offers the best aspect and the safest and most economical
                          option. Various approaches to rooftop mounted PV arrays are illustrated in Fig. 10.3.
                          Typically, the integral mount shown would be used with new construction, replacing
                          the conventional roofing material. The use of frameless laminates can reduce costs
