Rooftop solar power – An inevitable trend in the green era

Điện mặt trời áp mái - Xu hướng tất yếu trong kỷ nguyên xanh

A roof is not only for shading, but can also generate energy for life. Rooftop solar power opens a new era, where every family and business can proactively source clean, economical and environmentally friendly electricity. With rooftop solar power systems, people are gradually moving closer to a green future - where energy comes from the nature around us.

What is solar rooftop? Structure and operating principle

Concept

Rooftop solar power is a system of installing solar panels on the roof, metal roof or concrete roof, helping to convert sunlight into electricity for use in daily life or production. This is one of the most popular rooftop solar power solutions today, highly appreciated for its ability to take advantage of empty space on the roof, save costs and be environmentally friendly.

This system is suitable for households, businesses, factories or commercial buildings, bringing significant energy savings without changing the existing structure.

Structure and operating principle

A complete rooftop solar power system usually includes the following main components:

Working principle:
When sunlight hits the solar panel, the energy is converted into direct current (DC). The inverter then converts it into alternating current (AC) – the type of electricity that your home or business uses. Solar power will be prioritized for the load, and any excess electricity (if any) will be fed into the national grid through a two-way meter.

Outstanding benefits of installing rooftop solar power

Installing rooftop solar power not only saves costs but also brings many long-term economic and environmental benefits.
Save electricity costs:
Rooftop solar power systems can reduce monthly electricity bills by 60–80%, depending on the scale of installation and usage needs. With an average lifespan of 25–30 years, this is a stable and sustainable investment.Tiết kiệm điện năng từ việc lắp điện mặt trời áp mái

Make effective use of roof space:
Installing solar panels on the roof helps optimize the building area, both generating electricity and reducing roof heat, making the interior space cooler and saving air conditioning electricity.

Environmentally friendly:
Rooftop solar energy helps reduce CO₂ emissions, contributing to the fight against climate change and moving towards Vietnam's green development goals.

Increase the value of the project:
Buildings with rooftop solar power systems are often more highly valued for their utility and aesthetic value, especially in the trend of "smart homes - green buildings".

Quick return on investment – ​​long term use:
The average payback period is only 2-3 years, after which users enjoy virtually free electricity for the next 20 years.

Common configurations of rooftop solar power systems

Depending on usage needs and roof type, rooftop solar power systems are divided into many different configurations:

• Grid-connected rooftop solar power system:
  Most popular, suitable for households and businesses with stable grid electricity. Surplus electricity can be connected to the EVN grid.

• Hybrid solar power system (grid-connected with storage):
  Combining battery storage and grid connection, helping to maintain operation even during power outages.

• Independent solar power system:
  Using energy entirely from solar panels and storage batteries, suitable for areas without grid electricity.

In addition, users can choose to install rooftop solar power on many different types of roofs such as corrugated iron roofs, tile roofs, concrete roofs or factory roofs, depending on the design of the project.

Practical application: Installing rooftop solar power in households and businesses

For households:
Rooftop solar power systems help reduce electricity costs significantly, especially during peak hours. In addition, roofs with solar panels also reduce heat absorption, making the house cooler and more comfortable in the summer.

For businesses and factories:
Because production activities mainly take place during the day - coinciding with the sunny season, installing a rooftop solar power system helps optimize electricity usage efficiency, reduce grid load and save operating costs.
At the same time, this is also an important step to help businesses achieve ESG certification, enhance brand image and meet international partners' requirements for sustainable development.
