A good home PV power plant has two major characteristics: high power generation and stable operation.
And such a good home photovoltaic power plant has two foundations:
1. Quality product quality;
2. High-quality installation and operation and maintenance services;
Today, I would like to introduce to you the factors of the exclusion of equipment, how to use the simplest and most intuitive method to identify the quality of distributed PV installation at a glance, we mainly judge from four aspects:
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.
The components between a PV array are linked in series, and 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 and cause damage to the components.
3, installation inclination
The solar brackets mounting angle of the assembly 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 angle. However, if the tilt of the components of your system is too large, you should be careful, and the wind resistance of this system is worrying.
4. Certificate of conformity
Qualified products are a prerequisite for ensuring system power generation. 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.
