Overview

The 12 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 20 Mono 630W panels and needs roughly 72 – 84 m² of sun-facing roof.

Estimated output is 1360 – 1590 kWh a month, worth around 3.670.000 VND off the electricity bill, paying back in 4 – 5 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

Questions buyers ask about the 12 kW package

What is included in the 12 kW package?

20 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.

How much roof does the 12 kW package need?

About 72 – 84 m² of clear roof. That covers the 20 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.

How much power does the 12 kW package produce each month?

Roughly 1.360 – 1.590 kWh a month, worth about 3.670.000 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.

How long until it pays for itself?

About 4 – 5 năm, working from the 3.670.000 VND monthly saving above and the all-in cost of 96 triệu – 108 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.

Do I need to add a storage battery?

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 144 triệu – 156 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.

What kind of household is the 12 kW package for?

Most chosen. The most frequently chosen size. Multi-MPPT keeps it working well even when the roof faces several directions. The surest check is your last few electricity bills: compare your average monthly kWh against the 1.360 – 1.590 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.
