The Ocean Villas Story: Achieving Energy Independence by the Sea in Da Nang
In September 2025, a homeowner at The Ocean Villas, one of Da Nang’s most prestigious residential communities, took a major step toward energy independence. With support from LenX Energy, they installed a 10.32 kWp hybrid solar and battery system, designed to minimize grid reliance and maximize self-consumption. The result: a sustainable, reliable, and future-proof home powered by the sun.
Key statistics
- Location: The Ocean Villas, Da Nang, Vietnam
- Set up: 16 × LONGi Hi-MO 10X 645W panels, 10 kW hybrid inverter, 10.2 kWh lithium-ion battery
- System capacity 10.32 kWp
- Grid reliance reduction: Over 98%
- Environmental benefit: Offsetting 170+ tons of CO₂ over 25 years — equivalent to planting 7,000+ trees
Why LenX Energy?
With rising electricity costs and increasing demand for energy resilience, the homeowner sought a trusted partner to deliver a premium renewable solution that would match The Ocean Villas’ high standards. LenX Energy’s proven track record in hybrid system design, precision engineering, and local expertise made it the natural choice.
Designing for energy independence
The project was built around four core goals:
-
Maximize self-consumption of solar generation
-
Reduce electricity bills by over 90%
-
Provide reliable backup power during outages
-
Integrate seamlessly with the local grid
Site-Specific Challenges
Designing for The Ocean Villas’ coastal location required attention to detail:
-
Optimizing roof tilt and orientation for all-day solar capture
-
Performing shading analysis to prevent energy loss
-
Matching inverter and battery capacity with real-world usage
-
Ensuring system durability under tropical heat, humidity, and salt exposure
Want to make your home a powerhouse?
A smooth installation
Following a detailed site audit and energy analysis, LenX Energy’s engineering team designed a configuration that met 98% of the home’s annual energy demand.
System Layout
-
16 LONGi Hi-MO 10X panels were strategically placed for maximum sunlight and minimal shading.
-
The hybrid inverter acts as the system’s brain, managing energy flow between the solar array, battery, and grid.
-
Surplus solar power charges the battery during the day.
-
At night, the stored energy powers household loads, ensuring near-total grid independence.
Installation & Commissioning
-
Structural mounts were built using marine-grade, corrosion-resistant hardware, engineered to withstand coastal wind loads.
-
All electrical systems were installed to local and international safety standards.
-
The commissioning process included inverter-battery calibration, performance verification, and safety inspections to ensure reliable long-term operation.
Performance & Results
Since completion, the system has exceeded expectations:
-
98% reduction in monthly electricity bills
-
High self-consumption rate, optimizing every kilowatt of solar production
-
Reliable power for essential circuits during grid outages
-
Fast return on investment, thanks to significant energy cost savings
Through remote monitoring, both the homeowner and LenX Energy can:
-
Track solar generation in real time
-
Monitor battery charge/discharge cycles
-
Receive instant alerts for maintenance or optimization
Conclusion
The 10.32 kWp Ocean Villas hybrid system demonstrates how renewable technology can deliver near-total energy independence without compromising on design or performance.
With a 98% reduction in electricity bills, robust backup capability, and a strong environmental impact, this project stands as a benchmark for residential solar innovation in Vietnam — and a shining example of how LenX Energy continues to power a sustainable future.
