5 FAQs about [What to do if there are welds on the photovoltaic bracket]

What accessories do you need for PV installation?

Content Marketing Specialist for the Photovoltaic Industry Dedicated to providing thought-provoking articles on the PV industry Brackets are one of the most important accessories for installing PV, and there are many types to choose from in the form of connection, mounting structure, and installation location.

Why should you choose a PV bracket?

The choice of bracket directly affects the operational safety, breakage rate and construction investment of PV modules. Choosing the right PV bracket will not only reduce the project cost, but also reduce the post maintenance cost.

What are the different types of PV brackets?

At present, there are 3 types of brackets used in most PV power plants: fixed conventional bracket, adjustable tracking bracket and flexible PV bracket. This refers to the mounting system where the orientation, angle, etc. remain unchanged after installation.

Why should you choose a PV support system?

A safe and economical PV support system is the focus of attention. As an important component of a PV power plant, PV supports carry the main body of the PV power plant for power generation. The choice of bracket directly affects the operational safety, breakage rate and construction investment of PV modules.

What is the installation angle of PV modules?

The installation angle of PV modules in flexible mounts is generally small, usually 10°-15°. Flexible bracket is mainly applicable to scenarios such as mountainous projects with large slope (e.g. above 35°), fishery-photovoltaic and agricultural-photovoltaic projects with high headroom requirements.
