Solar Power: A Smart Saving Solution for Tet Holiday When Electricity Demand Surges

As Tet (Lunar New Year) approaches, many Vietnamese families begin shopping and equipping their homes with additional electrical appliances such as induction cookers, air conditioners, heaters, air fryers, ovens, washing machines, and decorative lighting systems. Family gatherings and increased cooking frequency cause electricity consumption to surge by 30–60% compared to normal days, resulting in significantly higher electricity bills.

According to energy experts, the use of electrical appliances in Vietnamese households has been rising rapidly in recent years due to the growing trend of smart kitchen appliances, expanded living spaces, air conditioning, and modern home gadgets. Meanwhile, electricity prices face pressure from rising production costs and peak demand, especially during the dry season.

Effective Reduction in Electricity Costs

With a 3–5 kWp solar system — suitable for most Vietnamese households — families can save between 1–2 million VND per month on electricity bills, depending on actual usage. Current payback periods typically range from 3–5 years, after which electricity becomes virtually free for the remaining system lifespan of 20–25 years (up to 30 years with high-quality equipment).

Rising Installation Trend Before Tet

Year-end and early-year periods are ideal times for home upgrades and long-term savings investments. From December to May, solar radiation levels are at their highest in many southern provinces, allowing systems to generate maximum output and deliver clear financial benefits from the very first year.

Not only households, but many shops, cafés, restaurants, and service businesses are also switching to solar power to ease the burden of operating costs during the Tet high season.

Sustainable Impact and Long-Term Benefits

Beyond economic advantages, solar power delivers important additional values:

• Reduces greenhouse gas emissions and supports environmental protection
• Cools the roof and lowers indoor temperatures
• Helps relieve pressure on the national grid during dry-season shortages

Energy organizations forecast that the proportion of Vietnamese households installing rooftop solar will continue to rise sharply in 2026, driven by three key factors:

1. Higher electricity demand, especially during peak seasons
2. More affordable equipment and installation costs
3. Improved public awareness of financial and environmental benefits

Clear Benefits Seen in Real Life

Many households that have installed solar systems report that the benefits go beyond just lower bills — they also gain greater independence and peace of mind, especially during prolonged heatwaves or when the national grid is under heavy load.
