To host a solar PV system, a roof must be able to support the weight of PV equipment—generally between three and six pounds per square foot. At the time of building construction, minimizing the amount of non-solar rooftop equipment will maximize the available area for installing a solar PV system in the future.
By selecting the right racking and attachment systems, you can ensure the stability and longevity of your solar installation. To increase the roof capacity for solar installations to be successful, you need to consider load redistribution as a way to shift the load from weak elements to stronger ones.
Both new and existing roof frames should have enough capacity to safely accommodate the additional load imposed from the installation of the solar system. The additional PV system weight can be incorporated in the design during early stage of the project life. The process is more complicated for existing building.
Roof mounted PV Solar Panels are typically supported by racking systems which come in two basic forms. The first is a mechanically fastened system and the second, the more common of the two, is a ballast restrained system. The mechanically fastened system penetrates through the roofing membrane and can be used in pitched roofs and flat roofs.
The larger the surface area required to support the PV system, the greater the potential impact on the building structure. The use of rooftop solar panels increases the superimposed dead load (SDL) of the roofing system and can have varying impact on a building depending on what material is being used for the structural system.
For a steel or wood low rise building, the relative additional weight from rooftop solar panels can add approximately 10% to the total factored design load of the roof structure. However, when considered in light of the total building costs, this additional costs may prove to be minimal.

Roof strengthening for Solar Panels
I question if this is really possible with a normal roof structure. For non horizontal roofs, a wind at 80MPH (say) against the roof surface is going to cause _enormously_ more downforce than the weight of the panel. For horizontal roofs, they need to be designed for quite hefty snow-loads anyway.
