Still curious? Call 1900-xxxx or drop us a Zalo — an engineer replies within 15 minutes.

For Vietnamese homes, typical payback is 4–6 years. Daytime-heavy businesses can hit 3–4 years. Panels last 25 years — after payback it's pure savings.
Grid-tied systems automatically pull from EVN when solar dips. Add a battery and you can run on solar at night and during outages.
Systems under 1MW don't need a permit — just grid registration with your local utility. We handle all paperwork for free.
Yes. We partner with VPBank, Techcombank, and MB Bank for 0% interest in the first 6 months, up to 36-month terms.
Both work. We have dedicated mounting for each roof type — no through-roof drilling, fully waterproofed.
