The four major minefields of residential distributed PV mounts include water leakage, load-bearing, maintenance and recycling issues, which require special attention during actual installation and operation.

Water leakage problems

The installation of distributed PV systems may affect the waterproof performance of the roof, especially if effective waterproofing measures are not taken during the construction process. For example, if the mounting bracket is not properly installed or the original waterproof layer of the roof is damaged, it may lead to roof leakage, and POWERACK's waterproof mounting bracket effectively solves this problem by its non-porous design, ensuring that the roof will not leak. In addition, the roof needs to be inspected in detail before construction to avoid leakage due to improper construction In addition, the roof needs to be inspected in detail before construction to avoid leakage due to improper construction.

Load-bearing issues

Roof loading is an important consideration for distributed PV system installation. The weight of the PV modules and racking needs to be within the roof's load-bearing capacity, otherwise it may cause damage to the structure of the house. For example, a 3KW domestic rooftop PV plant needs to be able to withstand a pressure of about 30KG/m², which is usually met by an ordinary residential roof. However, if the roof is not sufficiently load-bearing, reinforcement measures may be required, such as additional bracing or the use of lightweight materials.

Rights Defense Issues

During the operation of a distributed PV project, a roof owner may have a claim against the project company for roof damage (e.g., leakage, destruction) caused by the PV system. In judicial practice, roof owners need to prove the causal relationship between the roof damage and the PV project. Therefore, it is crucial to choose a reputable developer and sign a clear energy management contract to avoid subsequent disputes.

Recycling Issues

As distributed PV systems approach the end of their useful life, recycling of waste becomes a major challenge. PV modules contain a large amount of glass, steel, aluminum and other materials, which have high recycling value. However, China currently lacks a comprehensive system for recycling PV waste, resulting in some of the waste not being properly handled.
