Rooftop solar power: Development trend towards green, smart, sustainable urban areas

DNVN - In the context of the ever-increasing demand for electricity, finding solutions for efficient and sustainable energy use is a major concern for many households and businesses. Therefore, rooftop solar power is considered an effective direction, both helping to save costs and contributing to building green, smart and sustainable cities.

Rooftop solar power is a solar power system installed on the roofs of buildings such as houses, factories, office buildings, schools, etc. to exploit solar energy and convert it into electricity for direct use. With the advantages of not taking up land area, easy to install, and a system life of up to 20 - 25 years, this is a solution that is increasingly attracting the attention of many households and organizations in the capital.

In Hanoi, although the average number of sunshine hours is not as high as in the Central or Southern provinces, with more than 1,500 - 1,700 sunshine hours per year, the city still has the potential to develop rooftop solar power, especially in new urban areas, industrial factories and areas with favorable installation conditions. Taking advantage of existing roofs to invest in renewable energy systems not only reduces electricity bills but also helps reduce pressure on the grid, especially during peak hours on hot days.

According to calculations by many specialized installation and research units, with each 1 kWp of solar power system installed on the roof, customers can generate an average of 3.5 - 4.5 kWh/day. A system with a capacity of 5 kWp can generate over 150 kWh/month, equivalent to the electricity consumption of an average household in Hanoi.

 

Not only saving monthly electricity costs, rooftop solar power also contributes to reducing CO₂ emissions into the environment. It is estimated that 1 kWh of solar power generated will help reduce emissions of about 0.7 kg of CO₂ compared to electricity from fossil fuels. If this model is replicated, the potential to contribute to Hanoi's carbon emission reduction target is enormous.

Developing rooftop solar power is not only a personal electricity saving trend but also part of the green urban development orientation of Hanoi city. According to the National Strategy on Green Growth, solar power is one of the key solutions to reduce primary energy consumption, limit emissions and improve energy efficiency.

Many businesses and commercial buildings in Hanoi have pioneered the installation of rooftop solar power to demonstrate social responsibility, while increasing brand value towards sustainable development. Some schools, hospitals, and administrative agencies are also researching or putting into use solar power systems to serve the needs of lighting, air conditioning, water pumping, etc., contributing to reducing the operating costs of the State budget.

As one of the pioneering large-scale projects in energy saving practices, Corner Stone Building, located at 16 Phan Chu Trinh, has proactively installed a rooftop solar power system right on the roof of the building. Exploiting this clean energy source not only helps to significantly reduce monthly electricity costs but also demonstrates the unit's strong commitment to a green, environmentally friendly building model right in the heart of the capital.

 

In order to support customers in the process of accessing and deploying rooftop solar power, Hanoi Electricity Corporation (EVNHANOI) has been providing full information from technical consultation, legal support to operation and payment procedures. With modern infrastructure, a strong digital technology system and a team of experienced engineers, EVNHANOI is ready to play the role of a reliable intermediary between renewable energy generators and large electricity users in Hanoi.

In the coming time, EVNHANOI will continue to promote communication and popularize the benefits of rooftop solar power, encourage organizations and individuals to invest in solar power systems as a practical action with the community to respond to climate change and build Hanoi into a green, smart, modern city.
