1. What is a Solar Panel?
A solar panel is a device that absorbs sunlight and converts it into electricity through the photovoltaic effect. Each panel is composed of dozens or hundreds of solar cells, usually made from monocrystalline or polycrystalline silicon, linked into a standardized module for installation on rooftops, ground surfaces, or mobile structures.
As electricity prices rise and the greenhouse effect worsens, solar panels emerge as a cost-effective and eco-friendly energy solution. Rather than relying entirely on the national power grid, users can generate clean electricity from sunlight – no smoke, no noise, no CO₂ emissions.
Importantly, investing in a solar power system is no longer “a thing of the future” – it’s a rising trend today, from small households to large corporations and industrial zones.

2. Solar Panel Trends and Potential in Vietnam
Vietnam lies near the equator and receives abundant solar radiation year-round, with an average of 2,000–2,500 sunshine hours per year – an ideal condition for solar energy development.
Since 2019, the Vietnamese government has issued favorable policies to support renewable energy, including FIT (Feed-in Tariff) mechanisms for rooftop and farm-based solar systems. This has led to a surge in solar energy projects and an unprecedented demand for solar panels.
Global brands like JinkoSolar, LONGi Solar, Canadian Solar, AE Solar, and Hanwha Q Cells have entered Vietnam via distributors or assembly plants. Domestic enterprises such as SolarBK and Vu Phong Solar are also gaining recognition.

5. Buying Advice for Solar Panels
-
- Define your purpose: Do you want to cut electricity bills, invest for profit, or go off-grid?
-
- Avoid low-cost, uncertified panels: They degrade faster and often lack international certifications.
- Review technical specs carefully: Look for >18% efficiency, degradation <0.6%, PID resistance, and weather durability.
-
- Choose reputable suppliers: Ensure they offer warranty centers in Vietnam and transparent support policies.
Make sure the solar panel is compatible with your inverter for maximum system performance and lifespan. Contact 0968 68 8081 now for free consultation – from design to installation.
