5 kW solar bundle: 8 × Mono 630W panels, needing about 29 – 34 m² of roof. Output 540 – 640 kWh a month.
The 5 kW bundle is a complete system: panels, inverter, mounting frame and wiring materials costed as one set, rather than buying each part separately and matching them yourself.
The system uses 8 Mono 630W panels and needs roughly 29 – 34 m² of sun-facing roof.
Estimated output is 540 – 640 kWh a month, worth around 1.460.000 VND off the electricity bill, paying back in 4 – 6 years. The figure shifts with roof orientation, tilt and how sunny your region is, so only an on-site survey gives the number for your own roof.
Asia Energy quotes three ways: OEM manufacturing under your own brand, a distribution franchise, or retail with full installation. Free roof survey within 48 hours, warehouses in Hanoi and Ho Chi Minh City, nationwide delivery.

FAQ
8 Mono 630W panels, the inverter, the aluminium mounting frame, DC and AC distribution boards, the dedicated cabling and all ancillary materials — the full list is in the table above. The package price covers the roof survey, installation by Asia Energy's own crew rather than a subcontractor, and the handover documentation.
About 29 – 34 m² of clear roof. That covers the 8 panels plus gaps and a maintenance walkway. If no single area is big enough the array can be split into two or three groups, as long as they face the same way — different orientations call for an inverter with several MPPT trackers. The free 48-hour survey produces an actual layout drawing.
Roughly 540 – 640 kWh a month, worth about 1.460.000 VND off the electricity bill. The figure swings with the season: sunny months beat the upper end, a long rainy spell falls below the lower. What you save also depends on your tariff band — a household already in a high band saves more per self-generated kWh.
About 4 – 6 năm, working from the 1.460.000 VND monthly saving above and the all-in cost of 40 triệu – 45 triệu. After payback the power is free for the rest of the system's life — the panels carry a 25-year performance warranty. If electricity prices rise, the payback period shortens.
Not compulsory. Without a battery you run on solar by day and draw from the grid at night as usual — cheaper, and it pays back sooner. Adding storage brings the all-in cost to 60 triệu – 65 triệu, and in return you keep power during an outage and can use the daytime surplus. Where cuts are frequent, that difference earns its keep.
A household of 4 – 5. The size that suits most four- to five-person townhouses. The surest check is your last few electricity bills: compare your average monthly kWh against the 540 – 640 kWh this package produces. The system should cover most of what you use during daylight hours; it does not need to cover the whole month.
