Most LenX Energy customers save between 2.5–4 million VND/month, depending on their usage. Over time, your system typically pays for itself in 3–5 years, and continues generating savings for 20+ years.

Not at all. Many of our customers choose to cover 60–80% of their total usage — especially daytime hours when solar production is highest. This gives great savings without overbuilding the system.

It depends on your usage. For example:

• To offset 30 kWh/day (daytime use only), a 7 kW system is ideal.

We’ll help you size the system perfectly during your free consultation.

Typical system costs:

• 7 kW without battery: 120M–160M VND
• 7 kW with 10–15 kWh battery: 260M–380M VND

Larger systems for resorts, hotels, and factories are priced by custom quote.
