Chua Residence
- Urban Grid-Tied Solar Installation with 90% bill reduction
- System Size: 29.26 kWp
- Completion: 5-Jan-2022
- Quezon City, Philippines
Project Summary
The Chua Residence, located in a quiet subdivision in Quezon City, is a premium residential installation designed around substantial daily energy demand. The property supports both household living and multiple business operations, resulting in continuous daytime usage from office equipment, computing systems, and significant air conditioning loads.
Solaren engineered a system of appropriate scale to reflect this elevated consumption profile. Generation is structured to maximize daytime self-use while allowing surplus energy to be exported and credited against evening demand. The broader economic logic behind this approach aligns with Solar Energy Philippines: Smart Solution to Rising Power Costs, where solar becomes a strategic hedge against rising utility tariffs.
The system is fully compliant with approved net metering protocols and operates reliably across seasonal demand changes. Since commissioning, it has delivered consistent savings while maintaining performance standards expected of a premium residential installation. The result is a stable energy platform that supports both lifestyle and business activity under one roof.
