In the solar industry, it is a common practise for solar components supplier to provider warranty on the products they designed and offered, little people pay attention on what is into the fine print of the terms and condition. In the context of solar structure, there are UL2703
The Standard for Mounting Systems, Mounting Devices, Clamping/Retention Devices, and Ground Lugs for Use with Flat-Plate Photovoltaic Modules and Panels covers mounting systems, including mounting devices, clamping devices and ground lugs for use with photovoltaic modules and panels and contains requirements for ground-mounted and roof systems as part of a nonstructural building component.

In addition, UL 2703 is used to determine the fire classification of a rooftop-mounted PV system (which includes both a specific PV module and the racking system) as required for compliance with the building code requirements, which is to maintain the fire performance integrity of the roof. It is looking at the overall installation resistance to external fire exposure.
Further, while UL 3703, the Standard for Solar Trackers, involves rigorous inspection and evaluation of a tracker platform it also references UL 2703 for electrical requirements related to the mounting, bonding and grounding system.
Therefore, it is important to note that if a solar structure provider offers a warranty, the coverage should entail a lump sum eg, EUR5’000’000 for a certain duration such as maximum limit of identity combined for bodily injury and property damages specific to where the solar structure is installed.
This also remove an additional risk that Solar Engineering Construction Company (EPCC) faced, if the solar structure is badly design not to international codes and with no testing and proper building codes.
However, we have to take note that this insurance typically covers the design factor and not the workmanship factor. Thus, in the event of dispute, 3rd party auditor or the court will decide the judgement result.
