Residential solar installation team selection

When choosing a residential solar installation team, the following key aspects can be considered:

Qualifications and Experience

Legal qualifications: Check the company's business license, qualification certificates, and whether it holds relevant certifications (such as ISO quality management certification). It also needs to have legal qualifications such as the general contracting qualification for power engineering construction, the license for installation (repair, testing) of power facilities, and the professional contracting qualification for building mechanical and electrical installation engineering. These qualifications are important proofs that the installation team has professional capabilities and operates legally.

Rich experience: Understand the company's establishment time, the number of completed projects, and its reputation in the industry. An experienced team has a better understanding of various installation details and potential risks, and is capable of providing high-quality installation services. For instance, they might have dealt with various complex roof structures and lighting conditions and be able to provide more reasonable installation plans based on the actual situation.

Professional ability

Project consultation and customized solutions: A professional installation team should be capable of providing professional project consultation. Based on the roof structure of the residence, power demand, and regional sunlight exposure conditions, a reasonable and efficient photovoltaic power generation solution should be customized. In the initial consultation, the technical team should be able to clearly answer questions regarding equipment selection, installation location, budget and payback period, etc.

Equipment quality assurance: Reliable installation teams usually collaborate with renowned equipment manufacturers to provide high-quality photovoltaic panels, inverters, and other infrastructure. It is necessary to inquire clearly about the brand, warranty period and technical parameters of the equipment, and pay attention to the warranty period and after-sales service of key technical components such as inverters.

Service quality

Clear contract terms: Take the time to carefully review the contract to ensure that it includes all details such as the equipment list, construction plan, payment method, warranty scope and after-sales service. A reliable installation company should provide detailed and clear quotations and clearly list all charges to avoid "hidden" costs. For instance, the contract should clearly stipulate the responsibilities and compensation methods that the installation company should bear if it fails to connect to the grid.

Perfect after-sales service: The company's technical support team should have the ability to respond quickly and solve problems, providing long-term guarantees for photovoltaic systems. At the same time, find out whether the company provides regular inspection and maintenance services after construction to ensure the long-term stable operation of the photovoltaic power generation system.

Customer feedback

Refer to real reviews: By checking online customer reviews, forum discussions, and user experiences on social media, understand the actual service levels of different companies. Users' genuine feedback is often the most intuitive reference material, which can help judge the service quality and reputation of the installation team.
