Why choose EPCVINA Solar
EPCVINA Solar EPCVINA Solar
Unlike ordinary installers, EPCVINA comes from an MEP contractor background with 10+ years in electrical, plumbing, fire protection, and HVAC work. We do not just install solar systems; we engineer, execute safely, and support them long-term.
Every solar project is surveyed in person by licensed engineers, with technical drawings, roof-load calculations, waterproofing, grounding, lightning protection, and overvoltage protection for 25–30 years of stable operation.
MEP-grade design
Every system is engineered to MEP standards by licensed engineers for technical and legal compliance.
Electrical safety, lightning and grounding
Grounding, surge protection, and overvoltage safety are built to IEC standards to protect equipment and people.
Load, inverter, and battery control
Smart energy management prioritizes battery use at night and solar use during the day to minimize bills.
Roof waterproofing protection
Our crews protect roof waterproofing before and after installation so the roof structure is not affected.
Long-term maintenance
Scheduled O&M, remote monitoring, and fast issue handling within 24 hours throughout the system lifecycle.
Full MEP contractor foundation
EPCVINA brings electrical, HVAC, fire protection, and plumbing expertise into a complete solar delivery model.

Delivery process
6 Steps From Consultation to Operation
A professional, transparent, and MEP-standard workflow from the first contact until stable operation.
Average implementation time is 3-7 days depending on system size. We commit to schedule, site cleanliness, and full roof waterproofing before handover.
Initial intake
Customers reach us via hotline, Zalo, or the website form. Our team responds within 2 business hours and collects usage needs, monthly electricity bills, and usable roof area.
On-site survey
Certified engineers visit the site to measure the roof, assess sunlight, analyze electrical load, and inspect roof structure and existing wiring. We recommend the right capacity and system type (On-Grid or Hybrid).
Solution design
Our MEP engineers design the system to electrical-mechanical standards, including array layout, wiring diagrams, frame calculations, waterproofing, grounding, and surge protection. The draft is sent for review and approval.
Quotation
We provide a transparent itemized quotation: equipment (modules, inverter, mounting, cabling, distribution boards), installation labor, accessories, and delivery. Financing or installment support is available on request.
Installation & handover
Our experienced crew completes the work in about 3-7 days. We keep the site clean, fully address roof waterproofing before and after installation, and hand over with operating guidance and app monitoring instructions.
Maintenance & monitoring
EPCVINA monitors system output remotely through our monitoring platform. Scheduled maintenance every 6 months includes panel cleaning, connection checks, and frame tightening. Issues are handled within 24 hours.

FAQ
Common questions about solar power
Yes. For rooftop systems under 1 MWp, local utility notification is typically required. EPCVINA supports permitting, grid connection, and surplus power registration so customers do not need to manage the process alone.
Yes. A solar system can reduce monthly electricity costs by 70-90%. As electricity prices rise over time, the savings become even more significant. A typical 5 kWp system can save about 1.5-2.5 million VND per month.
The average payback period is 3-5 years for On-Grid systems and 5-7 years for Hybrid systems. After payback, you continue using electricity with very low operating cost for the remaining system lifespan of 20-25 years.
High-quality solar panels last over 25 years with performance degradation of around 0.5% per year. EPCVINA provides a 25-year panel warranty, 5-10 years for inverters, and 2 years for installation workmanship, plus ongoing support.
Yes, the system still generates power under low-sun conditions, though output may drop 50-80% compared to sunny days. The design already factors in annual average production, including rainy periods.
Maintenance costs are very low: mainly panel cleaning 2-4 times per year, which can often be done with clean water. There is no fuel cost or regular replacement of consumables. Professional maintenance is modest and long-term O&M packages are available.
