The most important thing I want to talk to you about today is how to find reliable construction partners. Look out for the "photovoltaic scam" oh!
The first step of how to find reliable construction units, what qualifications do we need to see?
For household photovoltaic projects connected to the public power grid of 380V and below, units with corresponding qualifications can be selected for construction. For example, mechanical and electrical installation and debugging personnel should have the corresponding qualification.
The selected construction unit and solar dc cable manufacturers must have the corresponding unit qualification, so as to carry out the construction, installation and commissioning of household photovoltaic project and other follow-up work.
It is also necessary to know whether the construction unit provides quality assurance and after-sales services such as follow-up operation and maintenance.
Whether the construction unit provides safety insurance and property insurance and other security guarantees.
really do not understand the friends, choose the domestic mainstream brand photovoltaic system manufacturers construction enterprises must be right.
The second step: how to judge the pros and cons of their photovoltaic system?
First of all, the appearance of the photovoltaic system is checked, including key products such as components, supports, inverters and meter boxes, and whether it has obtained the nationally recognized inspection certification. Here we suggest that you choose high-quality brand products, do not choose cheap products for the sake of temporary interests, and even go around to put together a set of photovoltaic systems. Although it seems that you do spend the least money to build a photovoltaic system, the later generation, maintenance stability and so on, will let you pay more manpower, material resources and financial resources oh!
During installation, you can compare the safety and aesthetics of the power station with the local household owner who has already installed household PV, and then negotiate with the installation provider to adjust the overall construction situation.
In terms of system performance, power generation can be compared with users without household photovoltaic installation; and compared with the stability of users who installed household PV.
In terms of after-sales operation and maintenance, it can be judged according to the timely rate of receiving orders and the timely rate of failure response. This point needs to remind you that we should pay special attention to after-sales service, which is why we are advised to choose big brands. Good after-sales is the guarantee of stable power generation income!
Know whether the power station provides insurance and other services, so as to avoid the loss of the power station caused by force majeure.
