Roof strengthening for Solar Panels
There doesn''t seem to be much on this in the forum. An increase in weight up to a certain proportion of the original roof weight shouldn''t be a problem, but obviously there''s a lot more to it than that, because the space underneath the solar panel means that there is a much bigger risk of wind blowing a solar panel off than a section of roof.

How to Test Insulation Resistance on Solar Panels
When measuring the insulation resistance of a solar panel that is actively generating electricity, it is essential to avoid using conventional methods designed for standard circuits. The voltage generated by photovoltaic cells can influence the test voltage, and if the array is grounded, there is a risk of damaging connected equipment.
Impact of wind on strength and deformation of solar photovoltaic
Studies of the effect of wind on solar panels have been carried out using CFD or wind tunneling (American Society of Civil Engineers, 2006; Hangan, & Vickery, 1999).
