How to identify the installation quality of the PV system

How to identify the installation quality of the PV system?

First,check whether the photovoltaic components are blocked

The components between a PV array are linked in series, and component occlusion affects the amount of power generated by the entire array. For example, if a PV array is 6 components, if part of one of the components is shaded due to occlusion, the power generation of the six components will be affected. In addition, occlusion can cause hot spots on the components, resulting in damage to the components.c profile steel suppliers

Second,check the connection cable routing

To install a distributed PV system, you need to connect cables. For high-quality construction, the wiring must be neat and regular. In addition, the cable will be installed outside the cable, which is both beautiful and protects the cable. The route is a standard for inspection and construction, but it is not a hard indicator. The route will basically not affect the power generation, but it can test the strength of the construction party. A quality construction team must pay attention to every detail.

Third,check whether the product has a warranty and a certificate of conformity

Qualified products are a prerequisite for ensuring the power generation of photovoltaic systems. The products of regular manufacturers have the factory certificate of conformity and the quality assurance documents. In addition, whether the component has a serial number or whether the inverter has a nameplate is also a message to check whether the product is from a regular manufacturer. Matters needing attention: Finally, final inspection is required according to the construction drawings z profile steel. If there is any problem, it is necessary to communicate with the construction party and the material staff in time; if there is any problem with the above, it is necessary to communicate with the construction party and the material staff in time.

Fourth,view the installation tilt of the component

The mounting angle of the component is a very complicated problem, and it is impossible to judge by the naked eye whether the inclination of the component is the optimum inclination. However, if the PV system’s component tilt angle is too large, then be careful, the wind resistance of this system will be worrying.
