Green living with solar energy

Rooftop solar power is becoming increasingly popular in residential and urban areas because it saves costs and protects the environment. In addition, support policies such as preferential electricity prices and tax exemptions have encouraged people to seek clean energy solutions.

In Son La , the province has actively promoted and encouraged households to use clean, renewable energy. To date, the province has 701 rooftop solar power systems in operation, with a total capacity of 61,479 kWp. Many households have proactively invested in integrated power storage systems to optimize the use of renewable energy, significantly reduce electricity costs and contribute to environmental protection. Businesses specializing in supplying and installing solar power systems in the province are also developing to meet this demand.

With 5 years of experience in supplying and installing solar power systems in Son La, Mr. Le Thanh Trung, Technical Director of Thanh Dong SOLAR Co., Ltd., said: Since the end of 2024, the price of solar power equipment and materials has decreased, so the number of customers choosing to install has increased sharply. To date, the Company has served more than 50 individual and corporate customers, installing solar power for both living and business. The Company carefully consults customers to choose an installation package suitable to their needs and consumption levels, ensuring the fastest investment recovery time.

Having paid an average electricity bill of 4 million VND/month for business purposes, Mr. Nguyen Manh Cuong, Group 4, To Hieu Ward, shared: In 2020, I invested 238 million VND to install 40 solar panels, producing an average of 61 kWh/day, enough for daytime use and selling excess electricity to the national grid. After 4 years, I have recovered enough capital. In March 2025, I continued to invest an additional 140 million VND to install storage batteries, ensuring stable electricity for daily life both at night and during power outages. Although the initial investment cost is high, in return the battery maintenance cost is very low (2 times/year). With an electricity consumption of 1.5 million VND/month or more, families should install solar power combined with storage batteries.

Investing in solar power is an essential solution to reduce the burden of increasing electricity costs, especially for businesses with high consumption. Mr. Vu Ba Chu, Group 3, To Hieu Ward, shared: Previously, my family's electricity bill for living and business was about 3 million VND/month, sometimes up to 5.5 - 6 million VND during peak periods. A month ago, I invested 178 million VND to install 18 solar panels and a maximum 12kW power storage system for continuous use day and night, the electricity bill has decreased by more than 70%. It is estimated that my family will recover the investment capital after only 5 years of use. Moreover, the advantage of a solar power system with storage is the ability to maintain a continuous power source, ensuring that the motel's business operations are not interrupted.

Currently, the market has many types of solar panels and storage devices. When deciding to invest in solar power, consumers need to pay attention to the quality and origin of the equipment to ensure safety and long-term efficiency. Buying separate components and manually installing them poses many risks of fire and explosion. Moreover, these systems are often not warranted in case of problems, forcing users to bear all the risks and repair costs.

In addition, households need to choose reputable, experienced suppliers, with products that have full quality certification and clear origin. At the same time, the installation must be performed by a team of professional technicians to ensure the system operates according to standards and is safe. Although the initial investment may be higher, in return, you will be assured of quality, stable performance and long-term warranty.

Rooftop solar power is a comprehensive solution, bringing dual economic and environmental benefits, not only helping households and businesses save significant costs and become self-sufficient in electricity, reducing the burden on the national grid, but also a practical action contributing to environmental protection, in line with the orientation of sustainable renewable energy development.
