What are PV installers most concerned about? A Case Study with Sanchez

In recent years, France’s solar market has grown rapidly, driven by government renewable energy policies and rising environmental awareness. Both residential and commercial installations are booming, making reliable suppliers critical for installers like Sanchez. Today, we’d like to share a solar story with you. Let us check out more!

Background

Customer: Sanchez, a professional solar installer in France.​

Purchase Quantity and Types: 15 sets of home solar systems, which are the popular models in France, such as 10kW, 15kW, 20kW and 22.4kW hybrid solar systems.​

Installation Type: ground installations and glazed tile roof installations.​

Customer's Focus: As an installer, in addition to product quality, Sanchez focuses on the supplier's technical support capabilities, after-sales service and problem-solving capabilities.

UE Services

Customized Technical Support:

Our technical team designed electrical connection diagrams and detailed installation layouts based on the specific parameters of each solar system and the installation environment, providing strong technical support for Sanchez's smooth installation.

Breaking down language barriers

Though this language barrier posed a unique challenge, our sales managers and technical team did not falter—instead, we adapted proactively. All interactions, whether technical datasheets, design documents, or quotes, were conducted in French. Even with the extra time and effort required, we ensured no single detail of Sanchez’s needs was overlooked. When Sanchez expressed uncertainty about wiring configurations or the functionality of protective devices, our technical team and sales managers collaborated to break down complex concepts into clear, step-by-step explanations, ensuring his full understanding.

To address Sanchez's focus on system safety, we equipped each system with additional protective devices, such as PV combiner boxes and battery combiner boxes (including circuit breakers and copper busbars). These protective devices effectively ensure the stable and safe operation of the solar system.

We also helped the customer calculate the most cost-effective packaging and logistics methods to ensure the safe delivery of the products while minimizing shipping costs.

This professionalism and patience not only streamlined his procurement process but also enabled us to receive Sanchez's trust and become his preferred solar supplier.

To meet Sanchez’s needs, our systems are equipped with high-performance products, with the 15kW PV system as a representative example:

After-sales service and problem-solving capabilities

After Sanchez received the goods, our team provided detailed user manuals and installation guidance to assist with on-site technical issues (e.g., wiring matching, inverter parameter configuration).

While installing one of the systems, Sanchez found that the inverter and lithium-ion battery were not communicating. Upon receiving this feedback, we quickly established a technical support team to promptly confirm the specific situation with Sanchez. By remotely upgrading the inverter, the issue was identified, and a replacement part was promptly shipped via air to him.

No delays, no excuses. Within no time, the system was up and running smoothly.

In China's solar industry, different suppliers adopt different approaches to cooperation. Some focus primarily on product sales, lacking technical guidance. This can sometimes lead customers to make choices that don't fully align with their needs.

Even after the purchase, the entire process can encounter obstacles. After-sales service often lapses after the goods are shipped, and when after-sales or logistics issues arise, getting timely assistance can be difficult. Imagine investing significant time and resources in building a solar system, only to be left stranded when you need guidance most. This isn't just a hassle; it gradually erodes the trust that should be built into every partnership. We hear stories like this all the time from many customers. This is very frustrating.

This is what sets us apart. For us, "Quality First, Service Foremost" isn't just a slogan; it's a commitment we uphold. We provide one-stop solar service, from pre-sales technical support to rigorous production oversight to ensure smooth delivery.

When (not if) a problem arises? We don't just respond; we're there. Our team is committed to helping you resolve any issue, no matter the time.

Because service isn't a one-time service for us. It's a commitment that goes beyond the sale, one that evolves with your needs and proves how important to choose a good supplier.

Conclusion

In the booming French solar market, we are committed to providing every customer with high-quality solar products and professional services. Our successful partnership with Sanchez fully demonstrates our strength, and we look forward to establishing long-term, stable partnerships with more customers.
