In Dominica, sky-high electricity bills ate into households' budgets, while frequent power outages and an unreliable grid disrupted daily lives—derailing cooking, work, and even critical emergency communication.
Our client Mr. Craig recognized the urgent need for a stable, dependable power supply—and he wasn't alone. Residents across his community shared the same frustration, desperate to escape the economic strain and daily hassles of unreliable energy. To address these issues, Mr. Craig sought customized, reliable solar solutions among Chinese PV enterprises and ultimately selected UE from many suppliers.
UE’s End-to-End Comprehensive Service
Customized System Design: Precision & Safety
A: The engineering team customized the configuration of UE inverters and wall-mounted lithium batteries based on the unique electricity consumption of each household, selecting the optimal capacity. Ultimately, four configuration options were determined: 5kW, 10kW, 15kW, and 20kW, corresponding to daily power generation of 20kWh, 40kWh, 60kWh, and 80kWh, respectively.
During the day, solar system generates electricity to power loads such as refrigerators and TVs, with the extra power stored in the batteries. At night, when the solar system stops operating, the lithium batteries supply power to the loads.
B: Additionally, the type of mounting brackets varies across different installation locations (e.g., zinc/concrete roofs, ground-mounted setups). Coupled with Dominica’s unique island topography—characterized by variations in building heights—the UE engineering team utilized professional measurement software to determine the optimal orientation and tilt angle for each set of brackets. This ensures structural stability while maximizing solar energy output.
During this phase, we also provided the working principle diagram (electrical connection diagram) and 3D rendering for each system. The client was highly interested upon receiving these documents, commenting:
“While I'm not familiar with the PV industry, your designs let me get a clear idea of how the system will look installed on my house.”
Cost-Optimized Logistics
To optimize shipping costs, we performed rigorous load calculations for a 40ft full container, maximizing packing volume while ensuring safe transportation. This planning ensured the client achieved 100% cost-effectiveness in freight.
Post-delivery technical support: empowering seamless deployment
Within one week of the client receiving the goods, we provided comprehensive technical parameter sheets for all products. UE engineers organized targeted online training sessions for the client's installation engineers, covering core operational and maintenance skills:
- MPPT connection and configuration
- Wiring guidance for inverters and batteries
- Troubleshooting common system malfunctions, etc
This hands-on training equipped the on-site team with the expertise to deploy and maintain the systems smoothly, while ensuring long-term reliable performance.
Winning Trust Through Professionalism
A critical milestone in the collaboration came when the client hesitated between UE and other renowned inverter brands. To help customers better understand inverters, our sales managers created a detailed, data-driven comparison list that clearly explains the core functions and safety features of UE inverters. It includes IGBT specifications (number of single/parallel tubes), number of relays, and electrolytic capacitors, etc.
Through this technological transparency, customized configuration, and unwavering patience, the customer ultimately chose UE's products.
Results & Impact
Mr. Craig and other local households now enjoy stable, clean power. Their electricity bills have dropped by 70-90%, and they’ve gained enhanced energy independence from the unstable grid.
Conclusion
This PV project provides a replicable model for other communities in Dominica. UE's customized design, end-to-end support, and transparency demonstrate that user-centric solutions effectively address local energy challenges while advancing renewable energy development.
