📋 Tender Overview
Rapidly increasing electricity demand, pressure to ensure electricity supply during hot weather and requirements to use green energy in the global supply chain are creating new impetus for rooftop solar power development. From the newly completed policies to the participation of all parties, a new market is being formed.

To promote this field, in recent times the Government and the Prime Minister have continuously issued many important mechanisms and policies. Decree No. 58/2025/ND-CP of the Government has created a legal corridor for the development of self-produced and self-consumed rooftop solar power. Next, Directive No. 09/CT-TTg and Directive No. 10/CT-TTg dated March 30, 2026 of the Prime Minister require ministries, branches and localities to promote economical and efficient use of electricity; Encourage the development of rooftop solar power at offices, businesses and households. Notably, on June 26, 2026, the Government continued to issue Decree No. 243/2026/ND-CP amending and supplementing a number of regulations in Decree No. 58/2025/ND-CP and Decree No. 57/2025/ND-CP. The new adjustments are expected to remove more obstacles during the implementation process, and at the same time create incentives for households, production establishments, businesses and businesses to invest in rooftop solar power. One of the notable changes is to increase the proportion of surplus electricity allowed to be sold to the national grid. According to the new mechanism, households, production establishments, businesses and businesses can sell up to 50% of excess electricity output, instead of the maximum 20% under previous regulations. Expanding the ratio of electricity sold is expected to help investors more effectively exploit generated output, improve financial efficiency and shorten capital recovery time. Decree No. 243/2026/ND-CP also expands the agreement mechanism in purchasing and selling surplus electricity. Accordingly, the electricity purchase price is negotiated by the electricity generator and electricity buyer on the basis of the price framework issued by the competent authority, instead of just applying a fixed price. This mechanism creates more room for electricity purchase prices to more closely reflect market conditions and the value of clean electricity sources. Download Energy expert Ha Dang Son: Rooftop solar power brings many benefits to both the power system and users. - Photo: VGP According to energy expert Ha Dang Son, in the current context, the need to develop clean electricity in general and rooftop solar power in particular is very urgent. From the perspective of good for the country, good for the family, rooftop solar power brings many benefits to both the electricity system and users. For the electricity system, the development of rooftop solar power helps reduce the need for electricity transmission, while also supporting meeting the electricity consumption needs of businesses at peak times of the day. More importantly, rooftop solar power contributes to reducing pressure on the electricity supply system in each area. If businesses in the Central and Southern regions promote the installation of rooftop solar power, these localities will have more room for power sources, thereby reducing pressure on the transmission system and creating conditions to support electricity supply to the North when necessary. From a user perspective, rooftop solar power also brings very clear benefits. The time of day when the temperature is highest is also often the time when the solar power system generates electricity most effectively. This creates synchronization between the production power source and the demand for electricity for cooling, thereby directly reducing the pressure on electricity consumption from the national grid. In addition, installing panels on the roof also helps reduce the roof surface temperature by about 2-3 degrees Celsius, thereby reducing the need to use air conditioning and saving more electricity. In terms of cost, the benefits for households and businesses are very clear. In case the incentive mechanisms of the Ministry of Industry and Trade are promoted towards self-production and self-consumption, users can also significantly reduce electricity costs by limiting electricity use at high price levels. For businesses, rooftop solar power also has strategic significance when many export markets, especially Europe, increasingly require the use of green energy in the production chain. Further, the development of rooftop solar power combined with energy storage solutions will contribute to improving the countrys ability to ensure electricity supply. It can be said that this is a solution that is very suitable for the current context, both helping to enhance energy security and bringing practical benefits to people and businesses, said Mr. Ha Dang Son.
